Covers choosing the source directory, writing frontmatter, placing the entry in src/docs.json navigation, adding redirects, and verifying with the lint and broken-link gates. Use when asked to add a new doc or page, move or rename a page, put something in the nav, or add a redirect.\nlicense: MIT\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# Add or move a docs page\n\nA page is not finished when the MDX file exists. It also needs a navigation\nentry, and a move or deletion needs a redirect. CI enforces both.\n\nRead `AGENTS.md` for the navigation map, the style guide, and the frontmatter\nrules. This skill covers the procedure around them and does not repeat them.\n\n## Step 1. Choose the source directory\n\nUse the \"Source directory summary\" table in `AGENTS.md` to go from subject to\ndirectory. Two traps:\n\n- Directory names do not match navigation names. `src/langsmith/fleet/` appears\n as \"No-code agents\"; `src/langsmith/managed-deep-agents*.mdx` appears under\n Build, not under a LangSmith menu.\n- Lifecycle menus mix products. Build draws from both `src/oss/` and\n `src/langsmith/`; Test, Deploy, and Monitor all draw from `src/langsmith/`.\n\nNever write to `build/`. It is Mintlify output, regenerated by `make build`.\n\n## Step 2. Write the page\n\nRequired frontmatter:\n\n```yaml\n---\ntitle: Clear, concise page title\ndescription: SEO summary with no markdown, no links, and no backticks\n---\n```\n\nFor OSS pages that differ by language, use `:::python` and `:::js` fences in one\nfile rather than writing two files. The build pipeline emits both versions.\n\nTake every fact on the page from the product source, not from memory, a sibling\ndocs page, or the request that asked for the page. This covers behavior,\ndefaults, field names, version minimums, and examples. Use the\n`verify-against-source` skill to find the repository that owns each claim. Never\nfabricate a value to fill a gap. Leave the claim out, and list what you could\nnot confirm in the pull request body and in your reply to the requester.\n\n## Step 3. Add the navigation entry\n\nNavigation lives in `src/docs.json` under `navigation.products`. There are two\nproducts: `products[0]` is AGENT DEVELOPMENT LIFECYCLE (Home, Build, Test,\nDeploy, Monitor) and `products[1]` is PRODUCTS AND SETUP (LangSmith setup, LLM\nGateway, No-code agents, Engine, Deep Agents Code).\n\nEach menu item is addressed by its `item` key, then nests one of two ways:\n\n- `menu[].tabs[].pages[]` for most menu items.\n- `menu[].dropdowns[].tabs[].pages[]` for Build, which has Python and\n TypeScript dropdowns.\n\nA `pages` array holds page-path strings and `{\"group\": ..., \"pages\": [...]}`\nobjects, nested to any depth.\n\nThree rules:\n\n1. **A language-versioned OSS page needs two entries.** Build page paths carry\n the language segment (`oss/python/deepagents/overview` and\n `oss/javascript/deepagents/overview`), so one new page means one entry in the\n Python dropdown and one in the TypeScript dropdown. Omitting the TypeScript\n entry is the most common miss.\n2. **Page paths omit the `src/` prefix and the file extension.**\n `src/langsmith/sandboxes.mdx` is `\"langsmith/sandboxes\"`.\n3. **A new group leads with an index page:**\n `\"pages\": [\"group/index\", \"group/page\"]`.\n\nIntegration pages are the exception. Add them to the component's `index.mdx`\ninstead, and touch `docs.json` only when creating a brand-new component group.\n\n## Step 4. Add redirects for a move, rename, or deletion\n\nFor a move or rename of a file that was already on `main`, run the repo's mover first. It rewrites cross-references\nacross the corpus, which hand-editing misses: every link to the page in every\nform (`/oss/langchain/x`, `/oss/python/langchain/x`, `href=\"...\"`), plus the\n`src/docs.json` nav entries and redirect destinations that name it:\n\n```bash\nuv run docs mv src/langsmith/old-name.mdx src/langsmith/new-name.mdx --dry-run\n```\n\nRead any `Left ... links unchanged` warning in the output. It marks links the\nmover could not rewrite safely, such as an unversioned `/oss/integrations/...`\nlink that also reaches the other language's page. Fix those by hand.\n\nDrop `--dry-run` once the preview looks right. The mover does not add a\nredirect, so add one to the `redirects` array in `src/docs.json`:\n\n```json\n{ \"source\": \"/langsmith/old-name\", \"destination\": \"/langsmith/new-name\" }\n```\n\nRedirect paths are site paths and start with `/`. A language-versioned page\nneeds a redirect per language, plus one for the unversioned path if the old URL\nhad one.\n\n`scripts/check_removed_pages_redirects.py` runs in CI and fails the PR when a\npage leaves the navigation and its source file is gone with no redirect. The\nsame script fails when `docs.json` names a page whose file does not exist, so a\ntypo in a page path is caught there rather than at build time.\n\n## Step 4b. Two traps that fail silently\n\n### Extract a snippet once a block appears on three pages\n\n`AGENTS.md` covers how to add a snippet. The rule for **when**: the same block\nrepeated on three or more pages becomes one file under `src/snippets/`. A status\ncallout duplicated across a page family means the wording change that retires it\nis an edit to every page in the family, and one will be missed.\n\nVerify a new snippet reaches the build. The pipeline rewrites snippet imports to\nlanguage-specific paths, so `/snippets/langsmith/x.mdx` becomes\n`/snippets/python/langsmith/x.mdx` in the output, and a missing target renders as\nnothing at all rather than as an error:\n\n```bash\nls build/snippets/python/langsmith/.mdx build/snippets/javascript/langsmith/.mdx\n```\n\n### Editing a heading moves its anchor\n\nA heading's slug is derived from its text, so rewording one silently breaks every\n`#anchor` link pointing at it, including links from other pages and entries in\n`src/docs.json`. Grep before editing:\n\n```bash\ngrep -rn 'use-with-the-langsmith-gateway' src/ --include=*.mdx --include=*.json\n```\n\nChanging only capitalization is safe, because slugs are lowercased. Changing a\nword is not, and needs either a reworded inbound link or a redirect.\n`` and `` accept an explicit `id`, which is how to keep a\nlanding spot that is no longer a heading.\n\n## Step 5. Verify\n\nRun all three, in this order:\n\n```bash\nmake lint_prose FILES=\"src/path/to/page.mdx\"\nmake build\nmake broken-links-with-anchors\n```\n\nWhen `make build` fails with `Required uv version >=0.9.26 does not match the\nrunning version`, the local `uv` has drifted from the one `pyproject.toml`\nexpects. Run the pipeline directly rather than working around the build:\n\n```bash\nPYTHONPATH=\"$(pwd)\" .venv/bin/python -m pipeline build\n```\n\nA fresh git worktree has no `.venv`, and the same version check blocks\n`uv sync` from creating one. Point at the main checkout's interpreter instead;\n`PYTHONPATH` still loads the pipeline code from the worktree:\n\n```bash\nPYTHONPATH=\"$(pwd)\" /.venv/bin/python -m pipeline build\n```\n\nA fresh worktree's `.mise.toml` is also untrusted, so the first commit fails\nat the Vale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix.\n\n`make broken-links-with-anchors` depends on `build`, so it fails the same way.\nIts link-check half runs on its own once the build output exists:\n\n```bash\ncd build && mint broken-links --check-anchors | tee /tmp/bl.txt\ncd .. && python3 scripts/filter_mint_broken_links.py --check-anchors --input /tmp/bl.txt\n```\n\nRead `make broken-links-with-anchors` output by skipping to the `⎿` lines. Those are the only\nreal failures. A bare filename with no indented lines beneath it is an\nOpenAPI-generated page that exists at deploy time but not locally.\n\nFix every Vale finding. CI blocks on `lint_prose`, and its most common failure is\na spaced em dash (`word — word` must be `word—word`).\n\n## Step 6. Review the prose\n\nOnce the edit is complete and before committing, invoke the `docs-review` skill\non the files this pass changed. It runs in working-tree mode, so it needs no\ncheckout, and it covers the style-guide rules Vale cannot see: passive voice,\nfiller, product versus common noun capitalization, structure conventions, and\nlink text.\n\nRun it on finished edits only. A review of a half-written section produces\nfindings that go stale as soon as writing resumes.\n\nSkip this step for a change too small to have prose in it, such as a pure\n`docs.json` reorder or a redirect-only fix.\n\n## Step 7. Open the pull request\n\nFollow the `open-docs-pr` skill to commit, write the PR description, push, and\nwatch the checks. If the change belongs on an existing PR, use `docs-edit`\ninstead.\n\n## Checklist\n\n- [ ] File in the directory the source-directory table names, not `build/`.\n- [ ] Frontmatter present, `description` free of markdown.\n- [ ] Every claim checked against product source; unconfirmed claims cut and\n listed in the PR body.\n- [ ] `src/docs.json` entry in the right product, menu item, tab, and group.\n- [ ] Both language entries added if the page is language-versioned.\n- [ ] Index page first if a new group was created.\n- [ ] Redirect added for every moved, renamed, or deleted path.\n- [ ] Inbound `#anchor` links checked before any heading was reworded.\n- [ ] A block now on three or more pages extracted to `src/snippets/`, and its\n built `python/` and `javascript/` targets confirmed to exist.\n- [ ] `make lint_prose` clean, `make broken-links-with-anchors` shows no new `⎿` lines.\n- [ ] `docs-review` run on the changed files, findings addressed.\n- [ ] PR opened with `open-docs-pr`, checks green.\n",".agents/skills/docs-restructure/SKILL.md":"---\nname: docs-restructure\ndescription: Restructure documentation that spans several pages. Covers splitting a page that has grown too long, moving sections between pages, retiring a page, and fixing a topic documented in two places at once. Use when asked to streamline, simplify, consolidate, or reorganize docs, or when a page review keeps producing edits without the page getting shorter.\n---\n\n# Restructure docs across pages\n\nThe failure this skill prevents: an agent asked to \"streamline this page\" reorders\nits sections, collapses them into accordions, retitles them, and tabulates them,\nthirty times over, while the page gets longer. The page was never the problem.\nThree of its sections already existed on sibling pages.\n\nSingle-page skills cannot see that. `add-docs-page` owns one page's lifecycle and\n`docs-edit` owns one page's diff. This skill owns the question they cannot ask:\n**is this content on the right page at all?**\n\n`AGENTS.md` holds the navigation map, the style guide, and the frontmatter rules.\nThis skill covers the procedure around them and does not repeat them.\n\n## Step 1. Establish the page family\n\nA page almost never lives alone. Find its siblings before reading it closely:\n\n```bash\nls src/langsmith/llm-gateway*.mdx # a flat-file family\nls src/oss/deepagents/ # a directory family\ngrep -n '\"langsmith/llm-gateway' src/docs.json # what the nav groups together\n```\n\nThe nav grouping is the better signal when the two disagree: pages a reader\nmoves between are the pages whose content can be confused.\n\nThen list every heading in the family, so you are working from the whole shape\nrather than one file:\n\n```bash\ngrep -n '^## ' src/langsmith/llm-gateway*.mdx\n```\n\n## Step 2. Build a duplication map before writing anything\n\nThis is the step that does the work. For each H2 in the page you were asked to\nfix, search the rest of the family for the same content:\n\n```bash\ngrep -rn 'LANGSMITH_GATEWAY' src/langsmith/ --include=*.mdx\ngrep -rn 'Use a regional gateway' src/ --include=*.mdx\n```\n\nSearch for the distinctive noun, env var, or endpoint in the section, not for\nits heading. Duplicated content is usually retitled, which is why heading\nsearches miss it.\n\nRecord for each section: **does this topic already live somewhere else, and\nwhere?** Two copies that have drifted apart are the strongest finding available.\nIt means no page owns the topic, so both copies are edited independently and\nreaders get contradictions. In one real case the quickstart claimed TypeScript\nsupport for three providers while the sibling page said \"Python only.\"\n\nReport the map before editing anything. \"Three of these six sections duplicate\n`llm-gateway-api-formats`\" is the finding. The restructure is downstream of it.\n\n## Step 3. Assign one home per topic\n\nFor each topic in the map, pick the single page that should own it:\n\n- **Prefer a page that already exists.** A new page is warranted when the topic\n has no home and does not fit an existing one, not when it merely needs\n somewhere to go.\n- **Prefer the page a reader would search for**, not the page the content\n happens to sit on.\n- **Keep the most-linked URL.** Check before choosing, because inbound links\n decide which file survives a merge of two pages:\n\n ```bash\n grep -rn '(/langsmith/llm-gateway)' src/ --include=*.mdx | wc -l\n ```\n\n Folding content *into* the well-linked page and retiring the other one is\n usually cheaper than the reverse.\n\n## Step 4. Cut, do not relocate\n\nA section that duplicates a sibling gets **deleted** and replaced with one\nsentence pointing at the owner. It does not get moved, collapsed into an\naccordion, or shortened in place. An accordion still costs the reader the\ndecision of whether to open it.\n\nContent that has no home yet moves. Content that has one is already written.\n\nWhen you delete a section whose facts differ from the sibling's, the difference\nis a bug in one of them. Resolve it against the source before deleting, or you\nsilently pick a winner. See `docs-edit` for the verification procedure.\n\n## Step 5. Mechanics\n\nRetiring, renaming, or creating a page means navigation entries, redirects, and\ninbound links. `add-docs-page` covers all of it, including the anchor-stability\nand snippet traps. Follow it rather than improvising here.\n\nTwo additional things a restructure breaks that a single-page edit does not:\n\n- **Section anchors other pages link to.** Moving a section moves its anchor.\n Grep for `#the-anchor` across `src/` before the move and repoint every hit. A\n `` or `` can carry an explicit `id` to preserve a landing\n spot that is no longer a heading.\n- **Cross-page pointers that now point at the wrong page.** After moving a\n topic, the sibling pages that used to reference its old location need\n repointing, not just the page you edited.\n\n## Step 6. Verify\n\n```bash\nmake lint_prose FILES=\"\"\nmake build\nmake broken-links-with-anchors\npython3 scripts/check_removed_pages_redirects.py --base-ref origin/main src/docs.json\n```\n\nRead `broken-links-with-anchors` by skipping to the `⎿` lines; those are the\nonly real failures. Compare the count against the same command on `origin/main`\nso a pre-existing baseline is not read as a regression.\n\nThen review the prose with the `docs-review` skill, scoped to the files this\npass changed.\n\n## Step 7. Report what moved\n\nState, per page, what was **deleted**, what **moved**, and what was **added**,\nwith before and after line counts. A restructure that cannot show a page getting\nshorter has not restructured anything, and the line counts are what show the\nreviewer whether it did.\n\nName what you deleted rather than only what you wrote. A reviewer who asked for\na shorter page needs to see the cuts to agree with them.\n\n## Scope\n\nStay inside the page family named in the request. A restructure surfaces\nadjacent problems: stale model IDs, legacy version numbers, and the same\nduplication one directory over. Report them, and **ask before widening the\nsweep.** Fixing sixteen instances across a page family is a reasonable follow-on\ninside one pull request. Fixing six hundred across the corpus is a separate pull\nrequest and probably a tracked issue, because some instances are deliberate and\nsome live in generated files.\n\n## Checklist\n\n- [ ] Page family established from `src/docs.json`, not guessed from filenames.\n- [ ] Duplication map built and reported before any edit.\n- [ ] One owner chosen per topic; most-linked URL identified before merging pages.\n- [ ] Duplicated sections deleted and replaced with a pointer, not relocated.\n- [ ] Conflicting facts between copies resolved against source, not by picking one.\n- [ ] Redirects, nav entries, inbound links, and section anchors all updated.\n- [ ] Verification commands run, `⎿` count compared against `origin/main`.\n- [ ] Report gives per-page before and after line counts.\n- [ ] Anything outside the page family reported, not swept, unless asked.\n",".agents/skills/docs-code-samples/SKILL.md":"---\nname: docs-code-samples\ndescription: Use this skill when migrating inline code samples from LangChain docs (MDX files) into external, testable code files that are extracted by this repo’s snippet scripts and used as Mintlify snippets. Applies when extracting code blocks from documentation, creating runnable code samples, using snippet delineators, or wiring snippet output into MDX includes.\nlicense: MIT\ncompatibility: LangChain docs monorepo with Mintlify. Requires Python and Make (Node.js is also required for TypeScript samples).\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# docs-code-samples\n\n## Overview\n\nThis skill documents the workflow for moving inline code samples from LangChain documentation into standalone, testable files that this repo extracts into snippets for use in MDX using Mintlify.\n\n## When to use\n\n- Migrating inline Python, TypeScript/JavaScript, or Java code blocks from MDX to external files\n- Creating runnable, testable code samples for documentation\n- Setting up snippet extraction and Mintlify snippet includes\n\n## Directory structure\n\nCode samples live under `src/code-samples/` in folders that match the product:\n\n- `langchain/` — LangChain docs\n- `langgraph/` — LangGraph docs\n- `deepagents/` — Deep Agents docs\n- `langsmith/` — LangSmith docs\n\nExample:\n\n```\nsrc/\n├── code-samples/ # Source: testable code with snippet tags\n│ ├── langchain/\n│ │ ├── return-a-string.py\n│ │ └── return-a-string.ts\n│ ├── langgraph/\n│ │ ├── langgraph-sql-agent.py\n│ │ └── langgraph-sql-agent.ts\n│ ├── deepagents/\n│ │ └── example-skill.py\n│ └── langsmith/\n│ ├── trace-example.py\n│ └── trace-example.java\n├── code-samples-generated/ # Snippet output (gitignored)\n│ ├── return-a-string.snippet.tool-return-values.py\n│ ├── return-a-string.snippet.tool-return-values.ts\n│ └── ...\n└── snippets/\n └── code-samples/ # MDX snippets for docs (all products)\n ├── tool-return-values-py.mdx\n ├── tool-return-values-js.mdx\n └── ...\n```\n\n**Prefer one file per doc page or topic**: Collocate related snippets in a single code sample file whenever they belong to the same MDX page, tutorial flow, or feature (for example, setup plus invocation, or a do/don't pair). Use multiple `:snippet-start:` / `:snippet-end:` pairs in that file rather than splitting into several `.py` or `.ts` files. Reserve separate files for unrelated samples or when a page genuinely needs independent test entry points.\n\n**More than one snippet in one file**: A single code sample file can contain more than one named snippet using different `:snippet-start: snippet-name` and `:snippet-end:` pairs. Each snippet must have a unique name. Shared imports, helpers, and `:remove-start:` test harness code live once in the file; only the fenced regions between snippet tags appear in the generated MDX snippets.\n\n**When to split TypeScript samples into separate files**: Python samples can usually keep multiple snippets in one file because later definitions overwrite earlier ones at module scope. TypeScript and JavaScript cannot: `make test-code-samples` runs the entire `.ts` file, and every snippet's code executes in the same module scope. Split into separate `.ts` files when snippets would collide, for example:\n\n- Duplicate `import` bindings (for example two snippets both `import { interrupt } from \"@langchain/langgraph\"`)\n- Duplicate `const` / `let` / `class` / `function` declarations with the same name (for example two snippets both declare `const State = ...`)\n- Two self-contained snippets that each need their own imports and top-level setup\n\nKeep related snippets in one Python file when possible. For TypeScript, use one file per independently runnable snippet when imports or top-level bindings would conflict. Name sibling files clearly, for example `langgraph-interrupts-validate-conditional-edge-pattern.ts` and `langgraph-interrupts-validate-conditional-edge.ts`. Put shared test-only setup in `:remove-start:` blocks inside each file rather than importing between sample files.\n\nWithin a single TypeScript file, `:remove-start:` blocks and snippet regions share the same module scope when `make test-code-samples` runs the file. Do not import the same binding in both places. Keep imports that appear in the docs snippet inside the snippet; limit `:remove-start:` imports to symbols used only by the test harness (for example `Command`, `MemorySaver`) that the snippet does not import.\n\n## Step-by-step instructions\n\n### 1. Create the code sample file\n\nPlace the file under `src/code-samples/` in the folder for the product: `langchain/`, `langgraph/`, `deepagents/`, or `langsmith/` (for example, `src/code-samples/langgraph/langgraph-sql-agent.py` for LangGraph docs).\n\nUse a descriptive filename, for example, `return-a-string.py`, `return-a-string.ts`, or `traceable-pipeline.java`. When a doc page needs several code blocks for the same feature, add them as multiple snippets in one Python file (for example, `rubric-configure.py` with `rubric-configure-py` and `rubric-invoke-py`) instead of creating `rubric-configure.py` and `rubric-invoke.py`. For TypeScript, use one file per snippet when module-scope imports or bindings would conflict (see **When to split TypeScript samples into separate files** above).\n\n### 2. Add snippet delineators\n\nWrap the code that should appear in the docs with snippet tags:\n\n**Python:**\n```python\n# :snippet-start: snippet-name-py\nfrom langchain.tools import tool\n\n@tool\ndef get_weather(city: str) -> str:\n \"\"\"Get weather for a city.\"\"\"\n return f\"It is currently sunny in {city}.\"\n\n# :snippet-end:\n```\n\n**TypeScript/JavaScript:**\n```ts\n// :snippet-start: snippet-name-js\nimport { tool } from \"langchain\";\n// ... tool definition ...\n// :snippet-end:\n```\n\n**Java:**\n```java\n// :snippet-start: snippet-name-java\npublic class Example {\n public static void main(String[] args) {\n System.out.println(\"hello\");\n }\n}\n// :snippet-end:\n```\n\n**Go:**\n```go\n// :snippet-start: snippet-name-go\npackage main\n\nimport \"fmt\"\n\nfunc main() {\n\tfmt.Println(\"hello\")\n}\n// :snippet-end:\n```\n\n**Bash (cURL):**\n```bash\n# :snippet-start: snippet-name-sh\ncurl \"https://api.smith.langchain.com/api/v1/runs\" \\\n -H \"x-api-key: $LANGSMITH_API_KEY\"\n# :snippet-end:\n```\n\nChoose a unique `snippet-name` in kebab-case. All snippet names must include a language suffix: `-py` for Python files, `-js` for TypeScript/JavaScript files, `-java` for Java files, `-kt` for Kotlin files, `-go` for Go files, and `-sh` for bash/cURL files (for example, `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh`). This becomes the base of the output filename.\n\n### 3. Add runnable test code in remove blocks\n\nWrap any code that makes the sample executable but should not appear in docs.\n\n**Run snippet code before exiting.** `make test-code-samples` must execute the snippet body, not skip it. Do not put `raise SystemExit(0)`, `process.exit(0)`, or `exit 0` at the top of a file (or before `:snippet-start:`) so the test passes without running imports, constructors, or API calls. That only checks that the file parses; it does not validate function signatures, option shapes, or import paths.\n\nPlace `:remove-start:` blocks **after** the snippet when you can, so the harness runs assertions on values the snippet created:\n\n**Python (preferred):**\n```python\n# :snippet-start: example-py\nfrom deepagents import create_deep_agent\n\nagent = create_deep_agent(model=\"google_genai:gemini-3.6-flash\")\n# :snippet-end:\n\n# :remove-start:\nassert agent is not None\nprint(\"✓ example validated\")\n# :remove-end:\n```\n\n**TypeScript (preferred):**\n```ts\n// :snippet-start: example-js\nimport { DeepAgentsServer } from \"deepagents-acp\";\n\nconst server = new DeepAgentsServer({\n agents: { name: \"careful-agent\", interruptOn: { write_file: true } },\n});\n// :snippet-end:\n\n// :remove-start:\nif (!server) throw new Error(\"server not created\");\nconsole.log(\"✓ example validated\");\n// :remove-end:\n```\n\nFor samples whose docs show a blocking tail (for example `await server.start()`, `asyncio.run(main())`, or `agent.invoke()` with a live model), keep setup and construction in the snippet so types and signatures are checked, then move **only** the blocking call into a trailing `:remove-start:` block—or omit it when construction alone is enough:\n\n```python\n# :snippet-start: server-example-py\nserver = AgentServerACP(agent)\n# :snippet-end:\n\n# :remove-start:\n# Do not call await run_agent(server) here — it blocks on stdio.\nassert server is not None\nprint(\"✓ server-example validated\")\n# :remove-end:\n```\n\n**Do not** short-circuit before the snippet:\n\n```python\n# :remove-start:\nraise SystemExit(0) # BAD: snippet below never runs\n# :remove-end:\n\n# :snippet-start: example-py\n...\n```\n\nThe examples below show harness code that invokes behavior when the snippet defines callable helpers:\n\n**Python:**\n```python\n# :remove-start:\nif __name__ == \"__main__\":\n result = get_weather.invoke({\"city\": \"San Francisco\"})\n assert result == \"It is currently sunny in San Francisco.\"\n print(\"✓ Tool works as expected\")\n# :remove-end:\n```\n\n**TypeScript:**\n```ts\n// :remove-start:\nasync function main() {\n const result = await getWeather.invoke({ city: \"San Francisco\" });\n if (result !== \"It is currently sunny in San Francisco.\") {\n throw new Error(`Expected \"...\", got \"${result}\"`);\n }\n console.log(\"✓ Tool works as expected\");\n}\nmain();\n// :remove-end:\n```\n\nThe extraction script strips `:remove-start:` / `:remove-end:` content when extracting snippets.\n\n### 4. Test the code sample\n\nBefore extracting snippets, verify the code sample runs correctly:\n\n```bash\n# Test the file(s) you added (faster)\nmake test-code-samples FILES=\"src/code-samples/langchain/return-a-string.py\"\n\n# Or run all code samples\nmake test-code-samples\n```\n\nFor multiple files: `FILES=\"path1 path2\"`. Fix any failures before proceeding—do not extract snippets until the samples pass.\n\nTo run one product's samples, set `CODE_SAMPLE_PATHS` to space-separated directories under `src/code-samples/`, for example `CODE_SAMPLE_PATHS=\"src/code-samples/langsmith\" make test-code-samples`. It also narrows an explicit `FILES` list. CI runs one matrix leg per product this way (`oss` covers `langchain/`, `langgraph/`, and `deepagents/`; `langsmith` covers `langsmith/`), so a failure in one product never turns the other product's check red. A new top-level directory under `src/code-samples/` must be added to a leg in `.github/workflows/test-code-samples.yml`, or the workflow fails its coverage check.\n\nJava files (`.java`) under `src/code-samples/` are run using `jbang`. To keep CI green, Java samples must:\n\n- Print at least one line of output so it's obvious the sample ran\n- Exit successfully (code 0) when optional API keys are not set, for example:\n - `OPENAI_API_KEY` for LLM calls\n- Fail fast (non-zero exit) when a key is required for the sample to run, for example `manage-prompts-0-push.java` without `LANGSMITH_API_KEY`\n\n`make test-code-samples` runs every `.java` file under `src/code-samples/` in **lexical path order** (after all Python and TypeScript samples). That order is unrelated to section order in the docs. If one sample must run before another (for example creating a hub prompt before pulling it), name the source files so they sort correctly. For example, `manage-prompts-pull.java` runs before `manage-prompts-push.java` because `pull` sorts before `push`; use prefixes such as `manage-prompts-0-push.java` and `manage-prompts-1-pull.java` when you need push to run first.\n\nGo files (`.go`) under `src/code-samples/` are run with `go run` from `src/code-samples/`, which shares a single `go.mod`/`go.sum` at that directory (add new dependencies there with `go get`, then `go mod tidy`, similar to how `.ts` samples share `src/code-samples/package.json`). `go run .go` only compiles that one file, not its sibling files in the same directory, so — like Kotlin — put each snippet variant in its own file (`topic-before.go`, `topic-after.go`) rather than multiple snippets sharing one file: two files in the same package cannot both declare `func main()`. Go samples do not guard on missing keys — let the SDK call fail fast (matching Python's behavior) rather than skipping with a printed message. `make test-code-samples` runs `.go` files last, after Kotlin, in lexical path order.\n\nBash/cURL files (`.sh`) under `src/code-samples/` are run with `bash .sh` from `src/code-samples/`. Like Go, put each snippet variant in its own file (`topic-before.sh`, `topic-after.sh`) rather than sharing one file. Hide test-only setup (`#!/usr/bin/env bash`, `set -euo pipefail`, resolving a real ID/value for a `` shown in the docs) in `# :remove-start:`/`# :remove-end:` blocks so the visible snippet is exactly the illustrative curl command a reader would copy — including no shebang or `set -e` line. `curl` does not exit non-zero on an HTTP error status by itself, so when a script pipes a response into `jq` to extract a value used by a later request (for example resolving a project ID), add a hidden check that the resolved value is non-empty and not the literal string `null` before continuing, so a bad API response fails the test loudly instead of silently propagating into later requests. `make test-code-samples` runs `.sh` files last, after Go, in lexical path order.\n\nCheck formatting with:\n\n```bash\nmake lint\n```\n\nFix any ruff or mypy issues before proceeding. Run `make format` to auto-fix formatting.\n\n### 5. Run snippet extraction\n\nFrom the repo root:\n\n```bash\nmake code-snippets\n```\n\nTo limit extraction to specific samples (faster while iterating), set `CODE_SNIPPET_SOURCES` to space-separated repo-relative paths under `src/code-samples/`:\n\n```bash\nCODE_SNIPPET_SOURCES=\"src/code-samples/langsmith/trace.java\" make code-snippets\n```\n\nThis command:\n\n1. Runs `python scripts/extract_code_snippets.py` (line-based, Bluehawk-compatible; handles `/**` in TS strings). Optional env `CODE_SNIPPET_SOURCES` limits extraction to specific paths under `src/code-samples/`; other stems already in `src/code-samples-generated/` are left alone.\n2. Runs `scripts/generate_code_snippet_mdx.py` to produce MDX snippets in `src/snippets/code-samples/` (always regenerates MDX from everything under `src/code-samples-generated/`)\n\nOutput files:\n\n- `return-a-string.snippet.tool-return-values.py` → `tool-return-values-py.mdx`\n- `return-a-string.snippet.tool-return-values.ts` → `tool-return-values-js.mdx`\n\n### 6. Update the MDX file to use the snippet\n\nAdd an import at the top of the MDX file (after frontmatter):\n\n```mdx\nimport ToolReturnValuesPy from '/snippets/code-samples/tool-return-values-py.mdx';\nimport ToolReturnValuesJs from '/snippets/code-samples/tool-return-values-js.mdx';\n```\n\nReplace the inline code blocks with the snippet components:\n\n```mdx\n:::python\n\n\n\n:::\n\n:::js\n\n\n\n:::\n```\n\n## Naming conventions\n\n| Element | Convention | Example |\n|--------|-------------|---------|\n| Code file | Descriptive, kebab-case | `return-a-string.py`, `return-a-string.ts`, `traceable-pipeline.java`, `traceable-pipeline.kt`, `traceable-pipeline.go`, `traceable-pipeline.sh` |\n| Snippet name | Kebab-case with language suffix: `-py` for Python, `-js` for JS/TS, `-java` for Java, `-kt` for Kotlin, `-go` for Go, `-sh` for bash/cURL | `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh` |\n| MDX snippet (Python) | `{snippet-name}.mdx` (snippet name ends in `-py`) | `tool-return-values-py.mdx` |\n| MDX snippet (JS) | `{snippet-name}.mdx` (snippet name ends in `-js`) | `tool-return-values-js.mdx` |\n| Component name | PascalCase | `ToolReturnValuesPy`, `ToolReturnValuesJs` |\n\n## Script behavior\n\n`scripts/generate_code_snippet_mdx.py`:\n\n- Reads `*.snippet.*.py` and `*.snippet.*.ts` from `src/code-samples-generated/`\n- Wraps content in fenced code blocks (`` ```python `` or `` ```ts ``)\n- When a snippet contains a model string, expands it into a Mintlify `` with the seven quickstart provider tabs (Google, OpenAI, Anthropic, OpenRouter, Fireworks, Baseten, Ollama):\n - Python: `model=\"…\"` or `model = \"…\"`\n - TypeScript: `model: \"…\"` or `model = \"…\"` (including `let model = \"…\"`)\n - Only the quoted model ID is swapped per tab, so assignment vs property syntax is preserved\n - Put `# KEEP MODEL` / `// KEEP MODEL` on the line before a model string to leave that occurrence unchanged\n- Writes to `src/snippets/code-samples/{snippet-name}-py.mdx` or `-js.mdx`\n\nTo support additional languages, add config entries in that script.\n\n## Guidelines\n\n- **Prefer the plainest thing that runs.** Keep the snippet verbatim from the page, add hidden harness code only where CI differs from a reader's machine (a missing env var, a dataset name that must be cleared first), and do not add options, inputs, or indirection nobody asked for. The same applies to the runner and workflow around the samples: one job per product, re-run a job from the GitHub UI rather than adding an input for it, read what GitHub already knows (job names, conclusions) rather than passing artifacts around. If a change needs a diagram to explain, it is too much.\n- **Run snippet code in tests** — `:remove-start:` harnesses must not exit before the snippet runs. Let imports, constructors, and configuration execute so `make test-code-samples` catches wrong signatures, renamed options, and broken import paths. Put `SystemExit` / `process.exit` only after the snippet (or use them to skip a trailing blocking call such as `server.start()`, not the whole sample).\n- **Collocate related snippets** in one code sample file per doc page or feature when possible (Python and Java). Import each generated MDX snippet separately in the MDX file (for example, `` then `` from the same source file). For TypeScript, split into separate `.ts` files when snippets duplicate imports or top-level bindings; still import each generated MDX snippet in the MDX file the same way.\n- Do not mock LangChain internals (for example `unittest.mock.patch` on `init_chat_model` helpers) so that imports resolve real chat model instances. Do not use fake chat models in docs code samples (for example `GenericFakeChatModel`, `FakeListChatModel`, or other `langchain_core` testing fakes). Wire a real chat model (for example `ChatOpenAI`) so snippets match what readers run; `make test-code-samples` requires a valid API key when the sample calls the model.\n- Do not change `pyproject.toml` when making code sample changes.\n- Always run `make test-code-samples FILES=\"path/to/your/file.py\"` before `make code-snippets` to ensure new samples pass.\n- Run `make lint` once the code sample is written; fix any issues (or run `make format` to auto-fix).\n- Do not add code samples to linting ignore rules when making lint-related changes—fix the code instead.\n- `src/code-samples-generated/` is gitignored; regenerate with `make code-snippets`, narrowing to specific files with `CODE_SNIPPET_SOURCES` while iterating.\n- Reference `AGENTS.md` for docs style and rules.\n- Use `:::python` and `:::js` fences for language-specific content; the build produces separate Python and JavaScript doc versions.\n- For python tests, try to correct the type rather than adding `# type: ignore[arg-type]`\n",".agents/skills/docs-team-voice/SKILL.md":"---\nname: docs-team-voice\ndescription: Write or revise documentation prose so it reads like the rest of this site, in the docs team's shared voice. Covers sentence length, cross-link density, how to state defaults and conditions, naming exact identifiers, and what to cut in a revision pass. Use when drafting or rewriting a page, a section, a concept overview, a how-to, a callout, or landing copy.\n---\n\n# Write in the house voice\n\n`AGENTS.md` holds the rules a linter can check: no contractions, no first\nperson, no future tense, sentence-case headings, Oxford commas, spacing around\ndashes. Vale enforces most of them and `make lint_prose` is the gate, though\nVale does not scan inside JSX components such as `` and ``, so a\nclean run there proves nothing. This skill covers what a linter cannot check:\nrhythm, density, and the shape of a sentence that carries information.\n\nThe targets below are measured from this repository's own pages, not invented.\n\n## Keep sentences short\n\nMedian sentence length on this site is **13 to 15 words**. Roughly one sentence\nin twelve runs past 25 words, one in forty past 30. Treat 25 as the point where\nyou look for a split and 35 as a defect.\n\nOne idea per sentence. When a sentence carries two, split it and let the second\nstand alone.\n\n> The agent definition selects the model and core capabilities of a managed deep\n> agent.\n\n> Set the `compression` field to control how exported Parquet files are\n> compressed. When omitted, LangSmith uses `zstandard`.\n\nThe second example is two sentences where one long one would have hidden the\ndefault inside a subordinate clause.\n\nThe target is a floor as well as a ceiling. Keep the condition, the actor, and\nthe exact value even when they push a sentence long, and split it rather than\ndropping one of them to get under 15 words.\n\n## Link about half the time\n\nClose to half of all prose sentences here carry a link. Cross-linking is not\ndecoration: it is how a reader escapes a page that does not answer the question\nthey arrived with.\n\nLink a term on first mention only. Pointing forward at the end of a section is\nstandard, and **two pointer forms are both established**:\n\n> Refer to [Spend policies](/langsmith/llm-gateway-spend-policies).\n\n> For the full project layout, see [Project\n> structure](/langsmith/managed-deep-agents-project-structure).\n\nNeither is canonical. Different authors favor different ones, so match the form\nthe page already uses and do not mass-convert one into the other.\n\n## State defaults and conditions as bare facts\n\nPut the trigger first, then the behavior. No hedging, no \"please note\".\n\n> When omitted, LangSmith uses `zstandard`.\n\n> Defaults to the last 7 days, newest first.\n\n> Task planning is opt-in.\n\n> Non-zero exits and timeouts from `--startup-cmd` warn but do not abort the\n> session.\n\nConstraints read the same way, as plain statements of fact rather than warnings\nabout them.\n\n## Name the exact identifier\n\nBacktick every field, flag, value, environment variable, and status. Between a\nquarter and a half of prose sentences on this site contain one. Name the actual\nvalue rather than gesturing at it: `zstandard`, not \"the appropriate\ncompression\"; `CREATED`, `RUNNING`, `COMPLETED`, not \"the various statuses\".\n\n> If your API key is linked to multiple workspaces, specify the workspace in the\n> header with `\"x-tenant-id\"`.\n\n## Reach for a concrete example early\n\n\"For example\" appears in roughly one sentence in thirty, almost always followed\nby a real value rather than a shape.\n\n> For example, in SCIM, the resolved `sub` claim and SCIM `externalId` must\n> match in order for login to succeed.\n\nIf you cannot supply a real example, say less rather than inventing one. Never\nfabricate a field name, a response body, or a policy detail to fill a slot.\n\n## Address the reader, and prefer the active voice\n\nSecond person carries a quarter to a half of sentences, most heavily in\nprocedures and UI steps. Passive voice appears in only about one sentence in\neight, and usually where the actor genuinely does not matter.\n\n> When viewing a trace that was generated by a run in LangSmith, you can access\n> the associated server logs directly from the Details view.\n\nUse the product name as the subject when the reader is not the actor: \"LangSmith\nuses `zstandard`\", not \"we use `zstandard`\".\n\n## Revision pass\n\nRead the draft once looking only for these:\n\n- **Sentences over 25 words.** Split, or cut a clause.\n- **Hedges and filler.** \"simply\", \"just\", \"very\", \"basically\", \"note that\",\n \"be sure to\", \"in order to\", \"has the ability to\". These are near-absent from\n this site's prose, well under one percent of sentences. Delete or replace.\n- **A spaced em dash.** `word — word` fails `LangChain.DashesSpaces` and blocks\n CI. Prefer a comma, a colon, or two sentences, and reach for `word—word` only\n when nothing else reads. A bold label opening a paragraph takes a colon:\n `**Tier assignment**:`, measured at 177 uses in `src/` against 1 for the dash.\n- **A vague identifier** where the exact one belongs.\n- **A cut that took a fact with it.** A tightened sentence that lost its\n condition, its actor, or its exact value reads cleanly and says something\n else. Restore the fact and split the sentence.\n- **A first mention with no link**, and repeat mentions that are linked again.\n- **A claim you did not verify.** Check it against the product source with the\n `verify-against-source` skill, or cut it. Another docs page is not a source.\n Name every claim you could not confirm in the PR body.\n- **A fact that disagrees with a related page.** Grep `src/` for the feature and\n read the pages that cover it from another angle, such as a CLI reference or a\n permissions table. The `docs-edit` skill covers what to look for.\n- **An added \"key features\" list, or a horizontal rule** used to separate\n sections. Neither belongs here.\n\nThen run the gate:\n\n```bash\nmake lint_prose FILES=\"\"\n```\n\nFor a full review against the style guide, with the rule each finding breaks,\nuse the `docs-review` skill.\n",".agents/skills/docs-edit/SKILL.md":"---\nname: docs-edit\ndescription: Edit a docs page that already has an open pull request, or revise a page in place. Covers checking out the PR's own branch instead of cutting a new one, forked cross-repository PRs, reading the real diff, checking the edit against related pages, and the verification to run before handing off. Use when asked to edit, revise, fix, or review changes on a named PR, branch, or existing page.\n---\n\n# Edit an existing docs page or PR\n\nThe failure this skill prevents: an agent asked to \"fix the wording on PR 1234\"\ncuts a fresh branch, commits there, and opens a second pull request against a\nteammate's work. Land edits on the branch that already exists.\n\n## Step 1. Check out the PR's own branch\n\nWhen the request names a PR, by number or URL, work on that PR's head branch.\n\n```bash\ngh pr view --json number,title,headRefName,baseRefName,author,isCrossRepository,files\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse plain `git checkout `. Do not use `git checkout -b` or `--no-track`:\neach produces a net-new branch, and committing there opens a second PR against\nsomeone else's work.\n\nA worktree on the PR's own branch is fine, and safer when other sessions share\nthe main checkout. Pass the existing branch name, never `-b`:\n\n```bash\ngit fetch origin \ngit worktree add # tracks origin/\n```\n\nThis fails if the branch is already checked out in another worktree. Use that\nworktree instead of forcing a second one.\n\nmise trusts config files by path, so each new worktree's `.mise.toml` starts\nout untrusted. The Vale pre-commit hook runs through `mise exec`, and the first\ncommit fails with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree, then commit again. To stop this\nfor good, add the main checkout to `trusted_config_paths` in\n`~/.config/mise/config.toml`. It trusts every worktree created inside the\ncheckout, such as `.claude/worktrees/*`, but not sibling directories.\n\nA local branch whose name merely mentions the PR is not the same branch. Confirm\nthat `git rev-parse HEAD` matches the `headRefOid` from `gh pr view` before\nediting, and that the branch has an upstream:\n\n```bash\ngit rev-parse --abbrev-ref @{upstream} # fails when the branch tracks nothing\n```\n\nCut a new branch only when the edits are your own and no open PR exists to land\nthem on, or when the user asks for one. Branch from the latest `origin/main`,\nnever from a stale local `main`.\n\n### Cross-repository PRs\n\nWhen `isCrossRepository` is `true`, the branch lives on a fork. Use `gh pr\ncheckout `, which configures the fork remote, and confirm push access before\ncommitting. Without it, the edits are stranded locally.\n\n## Step 2. Read the real diff\n\n```bash\ngh pr diff \n```\n\nPrefer this over `git diff main...HEAD`. A stale local `main` silently inflates\nthat diff with unrelated commits, and a branch that already merged `main` once\ninflates it further. To compare against the live base instead, fetch first and\nuse `git diff origin/main...HEAD`.\n\n## Step 3. Edit\n\n`AGENTS.md` holds the rules that apply to every edit: the style guide,\nfrontmatter, syntax, and the navigation map. Two that matter most here:\n\n- Match the conventions of the file you are editing. Do not restructure,\n combine, or split pages unless asked.\n- Never fabricate examples, field names, UI labels, or policy details. Verify\n each factual claim against the source it describes, and state plainly what you\n could not verify.\n\nFor voice and sentence rhythm while drafting, use the `docs-team-voice` skill. For\nadding, moving, renaming, or deleting a page, including navigation and\nredirects, use `add-docs-page`. When the edit is really a question of which page\nthe content belongs on, use `docs-restructure`.\n\n### Verify claims against source, not against other docs\n\nA sibling docs page is not a source. It is another claim, written by someone who\nmay have been guessing too, and two docs pages that agree can both be wrong.\nCheck the implementation:\n\n```bash\ngh api -X GET search/code -f q='LANGSMITH_GATEWAY repo:langchain-ai/langchain' \\\n --jq '.total_count, (.items[]?|.path)'\ngh api repos/langchain-ai/langchain/contents/ --jq .content | base64 -d\n```\n\nPython and TypeScript live in separate repositories and drift apart, so a table\nwith a Python column and a TypeScript column needs both checked:\n`langchain-ai/langchain`, `langchain-ai/langchainjs`, and for some providers a\ndedicated repository such as `langchain-ai/langchain-google`. A package's\n`CHANGELOG.md` gives the version a feature landed in, which is what a minimum\nversion column needs.\n\nState plainly what you could not verify. \"I could not confirm the Baseten row;\nno gateway references in either candidate repository\" is a useful review note.\nSilently keeping an unverified claim is not.\n\n### Read the pages around the one you are editing\n\nA page is one of several that cover the same feature. Others reach it from\nanother angle: a CLI reference, a permissions table, a list of Chat surfaces, a\nsetup guide, the pages that link to it. An edit made to one page in isolation\nleaves the set contradicting itself.\n\nBefore editing, find the related pages:\n\n```bash\ngrep -rliE \"|\" src --include='*.mdx'\ngrep -n \"\" src/docs.json\n```\n\nRead each one, then check for:\n\n- **Contradictions.** The edited page and a related one give different setup\n steps, defaults, or requirements. For example, a feature page that sets\n `LANGSMITH_API_KEY` while the CLI page recommends `langsmith auth login`.\n Settle it against source, then fix whichever page is wrong.\n- **Duplication.** A procedure the edited page restates from the page that owns\n it. Link to the owner instead. When choosing the owner is the real question,\n use `docs-restructure`.\n- **Missing entry points.** A page that lists every surface, command group, or\n permission area of a product should mention the feature and link to it.\n- **Navigation placement.** A page filed in a group that does not match its\n subject. Report it; do not move the page unless asked.\n\nA related page tells you what to check, not what is true. When two pages\ndisagree, the source decides, as described in the section above.\n\nKeep edits to related pages small: a cross-link, a corrected fact, or a short\nentry that points at the owner page. Anything larger is a restructure, so ask\nfirst.\n\n### Never hand-edit generated files\n\nThese are written by a generator. Editing them looks like it works, then a\nscheduled run reverts it, and for the changelogs the edit has already gone out\nover RSS:\n\n| File | Generated by |\n|------|--------------|\n| `src/langsmith/changelog.mdx` and `src/snippets/langsmith/fleet-changelog.mdx` | the `changelog-weekly.yml` workflow (`scripts/changelog_pipeline.py weekly`), from merged langchainplus PRs |\n| `src/langsmith/self-hosted-changelog.mdx` | the helm changelog bot |\n| `src/langsmith/langsmith-platform-openapi.json` | `.github/workflows/refresh-langsmith-openapi.yml` |\n| `src/langsmith/agent-server-openapi.json` | PRs from the `langgraph-api` repository |\n| `src/snippets/deepagents-eval-category-matrix.mdx` | `scripts/refresh_deepagents_category_matrix.py` |\n| `src/snippets/langsmith/mda-oauth-catalog.mdx` | `scripts/refresh_mda_oauth_catalog.py` |\n| `build/` | `make build` |\n\nWhen one of these carries the problem you were asked to fix, fix the generator\nor the upstream source and say so. Do not edit the output.\n\n### When an instruction reverses an earlier one\n\nReviewers change their minds, and on a long thread they will ask for a format\nthey previously rejected. Converting a table to a list and then back wastes a\nround and loses the reasoning both times.\n\nWhen an instruction contradicts one you already applied, say so before applying\nit: name the earlier instruction, the change you made for it, and ask which to\nkeep. Two reversals on the same element mean the requirement is unclear, not\nthat the format is wrong.\n\n## Step 4. Verify before handing off\n\n```bash\nmake lint_prose FILES=\"\"\n```\n\nRun `make broken-links-with-anchors` as well when links, page names, or navigation entries\nchanged. For a prose review against the style guide, use the `docs-review`\nskill.\n\n## Step 5. Report\n\nSay which branch the edits are on and whether it is the PR's own branch. Name\nthe related pages you changed, and the ones you read and left alone. If\nanything could not be verified, list it. Do not push or force-push unless the\nuser asks. When the user asks you to push, the merge-state check and the check\nwatching in `open-docs-pr` apply here too.

Get the branch with\n `gh pr view --json headRefName`.\n2. **A branch name** is used directly.\n3. **Empty, with uncommitted changes present** means the working tree. Take the\n files from `git status --porcelain` plus\n `git diff --name-only --diff-filter=d origin/main...HEAD`. No checkout, no\n worktree: the files are already in front of you. This is the mode that runs\n after an authoring skill.\n4. **Empty, with a clean tree** means the current `HEAD` against `main`:\n `git diff --name-only --diff-filter=d origin/main...HEAD`.\n\nNarrow to `src/**/*.mdx` and `src/**/*.md`. If nothing changed, say so and stop.\nNever review anything under `build/`.\n\n**For modes 1 and 2, check out the target before inspecting anything.** Your\nworking tree is almost certainly on a different branch, and linting it silently\nreports on the wrong content.\n\nFor a PR, check the branch out in the main working tree so any edit that follows\nlands on the open branch:\n\n```bash\ngit stash list # confirm nothing is about to be lost\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse `git checkout `, not `git checkout -b` or a `--no-track` branch. A\nnew branch is only correct when the review is of `main`, or when the user asks\nfor a separate branch of their own edits. Confirm the checkout by grepping for a\nstring the diff added.\n\nFor a review with no edits to follow, a detached worktree is also fine:\n\n```bash\ngit worktree add --detach /review-wt origin/\n```\n\nDo all reading and linting inside it, and `git worktree remove --force` it when\nthe review is done.\n\nState the target, the resolved SHA or \"working tree\", and the file count before\ngoing further.\n\n## Step 2. Run Vale\n\nRun `make lint_prose FILES=\"\"`, in the main checkout or a worktree alike.\nThe target installs the Vale version pinned in `.mise.toml` into `.bin/vale` when\nit is missing, so a fresh worktree needs no setup beyond network access.\n\nVale is deterministic and CI blocks on it, so its output is not a judgment call.\nReport every violation with its file and line. If invoked with `--fix`, correct\nthem; otherwise list them.\n\nLint the merge-base version of each changed file as well, and report the\ndifference rather than the raw count:\n\n```bash\ngit show origin/main: > /base-\nmake lint_prose FILES=\"/base-\"\n```\n\nA file that already failed on `main` carries pre-existing debt the author did\nnot introduce. A file that was clean on `main` and fails now is this diff's CI\nblocker. Say which one it is, because attribution is the difference between a\nfinding the author has to fix and one they can reasonably decline.\n\nReading the diff text is not a substitute for either run. A patch shows added\nlines without their column offsets or their surrounding component, which is\nexactly what these rules turn on.\n\nVale covers terminology, contractions, first person, future tense, Oxford\ncommas, spaced em dashes, navigation-path arrows, and heading case. **Do not\nspend model judgment re-checking what Vale already checks**, with one exception:\nVale does not scan every part of an MDX file, so a clean run is not proof of\ncompliance. It misses content inside JSX components (``, ``, ``,\n``, ``) and inside table cells. A page can pass Vale with four\nspaced em dashes in it.\n\nGrep the mechanical rules yourself over any file whose diff touches those\nplaces:\n\n```bash\ngrep -nE ' — | – ' # spaced em dashes\ngrep -nEi \"\\b(don't|can't|won't|isn't|it's|you'll)\\b\" # contractions\ngrep -nE '\\b(we|our|us|I)\\b|\\bwill [a-z]+\\b' # first person, future tense\ngrep -n '→' # navigation arrows\n```\n\nReport a hit inside a component the same way you would report a Vale error: it\nwould be one if Vale could see it. A `—` used as an empty table-cell marker is\nfine and is not a finding.\n\n## Step 3. Check structure against the style guide\n\nRead the \"Structure conventions\" section of `AGENTS.md` in the repository root,\nthen check the changed hunks against it. For each finding, quote the rule you are\napplying.\n\nLook for these, and nothing else:\n\n- **A new section or page that does not open with a one-sentence definition** of\n what the thing is or does, followed by the benefit, then the task. Skip when\n the section continues directly from the one above it.\n- **Steps introduced without a colon lead-in**, or steps that are not imperative.\n Skip for a list that is not a procedure.\n- **Three or more options, parameters, or permissions written as prose** where\n `- **Term**: Explanation.` would carry them. Skip for fewer than three.\n- **A feature or class linked on repeat mentions**, or a first mention that is\n not linked. Skip when the repeat is far enough down the page to be a genuine\n re-entry.\n- **A permission, plan tier, or preview requirement stated after the steps it\n governs** rather than before them.\n- **A hard constraint hedged** (\"it is generally not possible to change this\")\n where the guide calls for a flat fact (\"Once set, it cannot be changed.\").\n\nPointer phrasing is deliberately absent from that list. Both the long form (\"For\nmore information, see [Page]\") and the short form (\"See [Page]\") are\nestablished. Do not convert between them in either direction.\n\n## Step 4. Check the style guide items Vale cannot see\n\nRead the \"Style guide\" section of `AGENTS.md`. Vale enforces the mechanical half.\nThese are the rules that need reading:\n\n- **Passive voice** where the actor is known. \"Feedback is treated as a signal\"\n hides who treats it. Skip when the actor is genuinely irrelevant or unknown.\n- **Filler and hedging**: \"Note that\", \"Specifically\", \"simply\", \"easily\",\n \"just\", \"very\", \"basically\", \"obviously\". Cut the word, keep the sentence.\n- **A pronoun, \"this\", or \"the above\" whose antecedent the diff removed.**\n Compression is the usual cause: the noun the sentence refers back to sat in a\n clause the edit cut. Name the thing again.\n- **A condition, default, or requirement the diff shortened away.** Compare the\n hunk against its base rather than reading the new text alone. A sentence that\n got shorter by dropping when the behavior applies, or what value it applies\n to, is a regression, and it lints clean. Quote \"Be concise: cut filler words\n and wordy phrases\" and name the fact the cut removed.\n- **Product versus common noun capitalization.** A capitalized feature name that\n appears nowhere else in the file, or that disagrees with the UI label used\n elsewhere on the same page, is the tell. Grep the file for the term's other\n casings before reporting.\n- **Bold in body text** beyond UI labels. Match what the rest of the page does\n rather than an abstract standard.\n- **Repetition inside the diff.** The same list of items enumerated twice in one\n short section, or a sentence restating the one above it.\n- **Link text** that does not describe its destination, and two different labels\n pointing at the same anchor.\n- **Version minimums written with `>=` in prose.** The convention is \"v0.153.4 or\n later\"; `>=` belongs only in package specifiers such as `langsmith>=0.3.13`.\n\nMeasure before reporting a convention violation. If you are about to say a\nheading form or phrasing is wrong, grep the repository for how often it already\nappears. A form used widely is established practice, not a defect, however much\nthe guide seems to prohibit it. Report the count either way.\n\nA diff can also **leave** a convention rather than break a new one. Lowercasing\nthe explanation in `- **Term**: Explanation.`, dropping a trailing period, or\nswapping a colon lead-in for a dash each reads as a harmless copy edit on its\nown. Compare the before and after of that exact form, then count both spellings\nacross `src/`. When the base was following the majority, the change is the\nfinding.\n\nMeasure the same way when the diff **adopts** a convention rather than breaks\none, because a repeated block has three parts and matching two of them still\nlands wrong:\n\n- **Component.** `` or `` or plain prose.\n- **Wording.** Byte-identical to the siblings, or subtly reworded.\n- **Placement.** Before or after the intro paragraph, relative to imports and\n the first heading.\n\nA status callout copied word for word from the one page in thirteen that puts it\nbelow the intro is a finding, and only a placement count surfaces it. Report the\ncount for each of the three.\n\nWhen the same block appears on three or more pages, say so: it belongs in\n`src/snippets/` rather than duplicated. See `add-docs-page`.\n\n## Step 5. Check the mechanics the diff implies\n\nOnly when the diff triggers them:\n\n- A new page: is it in `src/docs.json`, in the right product, tab, and group?\n- A renamed or deleted page: are inbound links and the `docs.json` entry both\n updated?\n- New internal links: root-relative, and free of `/python/` or `/javascript/`?\n- A new code block: does it carry a real language tag, and are imports sorted?\n- A page or heading that changed URL: is there a redirect?\n\nThe `add-docs-page` skill covers all five in detail. Point at it rather than\nrestating the procedure in a finding.\n\n## Step 6. Report\n\nGroup by file. For each finding:\n\n```txt\nsrc/langsmith/example.mdx:42\nRule: \"State requirements and constraints up front\"\nThe admin permission requirement appears after step 3, but governs all of them.\nSuggested: move it above the numbered list.\n```\n\nEnd with a one-line verdict: what blocks merge (Vale violations, missing nav\nentry, broken link) versus what is a suggestion.\n\nIf nothing turns up, say that plainly. \"No findings\" is a valid and useful\nresult, and is more useful than a manufactured one.\n\n## Running after an authoring skill\n\n`add-docs-page` invokes this skill at its verification step, in working-tree\nmode, on the files it just changed. Two constraints keep that useful:\n\n- **Review finished edits, not drafts.** Findings on a half-written section go\n stale as soon as writing resumes, and reporting them trains the reader to\n ignore the report. Run after the edit is complete and before the commit.\n- **Scope to the files the authoring pass touched.** Do not widen to the rest of\n the branch. If other files changed earlier and also want review, say so and\n let the user ask.\n",".agents/skills/docs-tooling-notion/SKILL.md":"---\nname: docs-tooling-notion\ndescription: Document new or changed docs-team tooling on the Notion tooling pages.

Duplicates drift, and drift is worse than\na long page. Before writing anything, search the other four pages for the topic.\nIf it already appears somewhere, update it there instead of adding a second\ncopy.\n\n## Step 1. Route the topic\n\n| Page | ID | Owns |\n|------|----|------|\n| [Docs tooling and agents](https://app.notion.com/p/3ca808527b178153839bff0f2831914c) | `3ca808527b178153839bff0f2831914c` | Parent directory. Page table, \"Owned elsewhere\" list, quick-answers FAQ. |\n| [Docs tech stack](https://app.notion.com/p/30c808527b178073876af57f7d87d8ca) | `30c808527b178073876af57f7d87d8ca` | The production site only: fencing, `src` versus `build`, build pipeline, navigation, integration docs. |\n| [Local setup and quality gates](https://app.notion.com/p/3c8808527b1781dcbaf5d04834a843bf) | `3c8808527b1781dcbaf5d04834a843bf` | mise and prek setup, the `docs` and `mint` CLIs, Vale, git hooks, broken-link triage, the CI matrix, preview deployments, publishing. |\n| [Docs automation and agents](https://app.notion.com/p/3c8808527b17815b81cbf92896b5c3ee) | `3c8808527b17815b81cbf92896b5c3ee` | Scheduled workflows and their cron times, the changelog agents, the #ask-docs intake agent, tracked skills, agent-instruction files, MCP servers. |\n| [Reference docs](https://app.notion.com/p/3c9808527b1781858ebbe92914b02970) | `3c9808527b1781858ebbe92914b02970` | The three LangSmith OpenAPI sources, reference.langchain.com, the `@[ClassName]` link map. |\n\nMost new tooling lands on **Docs automation and agents** (a workflow, script,\nagent, skill, or MCP server) or **Local setup and quality gates** (anything a\ncontributor runs on their own machine or that gates a PR).\n\nThe changelog **system** is not owned by these pages. [LangSmith release\nnotes](https://app.notion.com/p/31b808527b178026943ac2b1ae244021) owns fragments,\nthe fragment schema, and both pipelines. Link to it; do not re-explain it. These\npages keep only the runbook: deployment IDs, HTTP routes, required environment\nvariables, and recovery paths.\n\n## Step 2. Check whether it belongs in Notion at all\n\nDo not write a Notion page for something the repo already documents where people\nfind it. Deliberately excluded: `IDE_SETUP.md`, `.github/brand-guidelines.md`,\n`.github/pull_request_template.md`, `.github/CONTRIBUTING.md`, the issue\ntemplates, and the navigation map, which lives only in `AGENTS.md` because the Notion copy went stale once already.\n\nSkills are the same: a skill is its own authoritative reference. Name it on the\nNotion page, say what it covers and the one or two facts a reader needs in order\nto decide whether to open it, and stop there.\n\nUntracked tooling is not team infrastructure. Anything under a gitignored path\nis personal tooling and does not go on these pages.\n\n## Step 3. Write it\n\nFollow the `docs-team-voice` skill. Do not restate its rules here. The three that\nget missed most often on Notion pages: no first person, no spaced em dashes, and\ndefinition lists written as `- **Term**: Explanation.` with the colon outside the\nbold and a period at the end.\n\nOpen a section with a one-sentence statement of what the thing is, then what it\nenables, then the procedure. Close a substantial page with `## See also`.\n\n## Step 4. Edit safely\n\nFetch the page with `notion-fetch` before every edit. Then use\n`notion-update-page` with `command: \"update_content\"` and narrow\n`content_updates` pairs rather than rewriting the page.\n\nFive failure modes, each of which has already cost a debugging cycle:\n\n- **`old_str` must match the stored indentation exactly.** Tables are stored\n with no leading tabs; callouts do use tabs. A mismatch fails with an\n indentation hint.\n- **Never use `replace_content` on a page holding an uploaded image.** The\n fetched image URL is a short-lived signed S3 link, and rewriting the page body\n can break the image.\n- **A timed-out or async update may already have applied.** Updates default to\n `allow_async: true`. Fetch the page and verify before retrying anything that\n appeared to fail, otherwise the retry duplicates the block.\n- **Bold that contains inline code mid-sentence renders as stray asterisks.**\n Bold wrapping code entirely is fine. Reword so the two do not collide.\n- **In-page anchor links do not resolve.** Notion addresses blocks by ID, not by\n heading slug. Reference sections by name in prose.\n\n## Step 5. Add a row to the Detailed list\n\nThe parent page embeds a **Detailed list** database\n(`collection://3ce80852-7b17-8004-8735-000bc758a8cd`) holding one row per piece\nof tooling. Prose on a page is where someone reads about a thing; this database\nis where they find that it exists at all. It is easy to miss, because the parent\npage renders it as a single inline block.\n\nEvery new workflow, script, skill, agent, MCP server, or git hook gets a row.\nThe schema is Title, Description, Docs page (the URL of the page that explains\nit), Source (the repo paths it lives at), and Type, a select over `GH Actions\n(scheduled)`, `GH Actions (PR/CI)`, `Fleet agent`, `Deep agent`, `External bot`,\n`Skill`, `MCP server`, `Manual script`, and `Git hook`.\n\nQuery it with `notion-query-data-sources` before adding, so a rename becomes an\nupdate rather than a duplicate row. Renaming or moving a file means updating\n`Source` here too, not only in the prose: four rows still pointed at a skills\ndirectory that had been renamed months earlier, and every one of them read as\nplausible.\n\n## Step 6. Close the loop\n\nUpdate the parent page's page table when a page's scope changes, and repoint any\n`## See also` entry that is now wrong. Report which page was edited and what was\ndeliberately left out, so the routing decision is reviewable.\n",".agents/skills/open-docs-pr/SKILL.md":"---\nname: open-docs-pr\ndescription: Open a pull request for finished docs changes. Covers cutting the branch from the latest origin/main, the lint and link gates, the commit, writing the PR description in the repo's short format with the AI disclosure line, pushing safely, and watching the PR checks until they pass. Use when asked to open, create, put up, or submit a docs PR, or after add-docs-page or docs-edit finishes an edit that has no PR yet.\n---\n\n# Open a docs pull request\n\nThis skill starts when the edit is finished and ends when the PR is open and\nits checks are green. Editing a PR that already exists is `docs-edit`, not this\nskill: pushing a second PR against a teammate's work is the failure that skill\nprevents.\n\nThe rules every task follows live in `AGENTS.md`. This skill is the order to\napply them in.\n\n## Step 1. Branch from the latest main\n\nNever commit to `main`. Cut a new branch from a freshly fetched `origin/main`,\nnot from a local `main` that may be days old:\n\n```bash\ngit fetch origin main\ngit switch -c / --no-track origin/main\n```\n\n`--no-track` stops the branch from tracking `origin/main`, so a bare push\ncannot land on `main`.\n\nThe main checkout may be shared with other agent sessions that switch branches\nunder you. Prefer a worktree inside the checkout:\n\n```bash\ngit worktree add -b / --no-track .claude/worktrees/ origin/main\n```\n\nA new worktree's `.mise.toml` is untrusted, so the first commit fails at the\nVale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix. Run `make skills` in the worktree too if you use Claude Code.\n\n## Step 2. Run the gates\n\nRun each gate that applies to the change before committing. CI runs the same\nones, so a skipped gate becomes a red check later.\n\n- **Prose review**: Run the `docs-review` skill on the changed pages. It covers\n the style-guide rules Vale cannot see. Skip it for a change with no prose.\n- **Vale**: `make lint_prose FILES=\"\"`. Fix every error.\n- **Links**: `make broken-links-with-anchors` when links, page names, anchors,\n or `src/docs.json` changed. Read only the indented `⎿` lines.\n- **Code samples**: `make test-code-samples FILES=\"\"` when a\n file under `src/code-samples/` changed.\n- **Pipeline**: `make test` and `make lint` when `pipeline/`, `scripts/`, or\n `tests/` changed.\n\nNote which gates you ran. The PR checklist asks for them.\n\n## Step 3. Commit\n\nStage only the files the change touched, then check that nothing secret is\nstaged:\n\n```bash\ngit diff --cached --name-only\n```\n\nWrite the subject line in the form recent merged PRs use: `docs: ...` for\ncontent, `docs(): ...` when one product is involved, and `chore: ...`\nfor tooling. The body explains why, not what.\n\nDo not add a `Co-Authored-By` trailer for an AI agent. A ruleset on `main`\nrejects the Claude trailer at merge time, and squash merges carry branch commit\ntrailers into `main`.\n\n## Step 4. Write the PR description\n\nUse the sections in `.github/pull_request_template.md`: **Why**, **Changes**,\n**Review notes**, **Related**, and the checklist. Fill each one in, and delete\nany section that would be empty rather than leaving placeholder comments.\n\n- **Why**: The problem the change solves, in two or three sentences.\n- **Changes**: One bullet per meaningful change, naming the file or page.\n- **Review notes**: Where to look hardest, decisions the reviewer may disagree\n with, and every claim you could not verify against source. A preview link\n goes here once the preview deploys.\n- **Related**: Issues, PRs, Linear tickets, and Slack threads. Write\n `Closes [DOC-N]()` to let `sync-linear-issue-from-pr.yml` move\n the Linear issue with the PR.\n- **Checklist**: Tick only what you actually did in Step 2. Leave the rest\n unticked rather than claiming it.\n\nEnd with one plain sentence that discloses AI involvement, for example\n`Prepared with Claude Code.` Do not add the `🤖 Generated with [Claude Code](...)`\nbadge or any similar badge. The `check-pr-ai-attribution` check fails a PR\nwhose description carries one, because the squash merge would copy it into the\ncommit on `main`.\n\nWrite the description to a file and pass it with `--body-file`. A shell\nheredoc inside `--body \"$(...)\"` breaks on apostrophes in some shells.\n\n## Step 5. Push and open the PR\n\nConfirm the remote is a `langchain-ai` repository, then push with an explicit\nremote and branch. Never run a bare `git push`.\n\n```bash\ngit remote get-url origin # must be github.com/langchain-ai/docs\ngit push -u origin \ngh pr create --base main --head --title \"\" --body-file \n```\n\nOpen it as a draft (`--draft`) if it is not ready for review.\n`pr-welcome-comment.yml` requests reviewers from `.github/OWNERS` when the PR\nleaves draft, so do not request reviewers by hand unless asked.\n\nIf you later push more commits, first check that the PR has not merged. A push\nto a merged PR's branch lands nowhere:\n\n```bash\ngh pr view --json state,mergedAt\n```\n\n## Step 6. Watch the checks\n\n```bash\ngh pr checks --watch\n```\n\nFor a failure, read the log with `gh run view --log-failed`, fix the\ncause on the same branch, and push again. Editing the PR description reruns the\ndescription checks without a new commit.\n\nFor same-repo PRs, `create-preview-branch.yml` comments a preview URL. Forks do\nnot get one.\n\n## Step 7. Record tooling changes\n\nWhen the PR adds or changes a script, workflow, Makefile target, check,\nscheduled job, or skill, invoke `docs-tooling-notion` before handing off.\n\n## Report\n\nGive the PR URL, the branch, the gates you ran and their results, the state of\nthe checks, and anything you could not verify.\n","docs-release-watch/skills/deepagents-code/SKILL.md":"---\nname: deepagents-code\ndescription: Analyze Deep Agents Code releases against LangChain Deep Agents Code docs and prepare one-feature documentation updates.\n---\n\n# Deep Agents Code docs release skill\n\nUse this skill when the product is Deep Agents Code (Products and setup → Deep Agents Code).

Small judgment calls belong in the PR diff, not in an issue Q&A thread.\n- **Only** emit `integration-submission-error.md` for hard blockers where no reasonable listing is possible (for example, package missing from the registry, or language/package fields that cannot map to any component). Soft uncertainty is not a blocker.\n\n## Policy\n\n| Case | Action |\n|------|--------|\n| **≥50K monthly downloads** (PyPI or npm) **or** explicit maintainer feature override in the issue | Hosted MDX from the matching `TEMPLATE.mdx`. Correct `integration:` frontmatter. Do **not** set `featured: true` unless a maintainer asked. Remove any duplicate external YAML row for the same package. |\n| **Under 50K**, not featured | **External listing only.** No new hosted MDX. |\n\n## External listing checklist\n\n1. Measure downloads (do not invent counts):\n\n ```bash\n curl -s \"https://pypistats.org/api/packages//overall?mirrors=false\"\n curl -s \"https://api.npmjs.org/downloads/point/last-month/\"\n ```\n\n2. Add YAML under the correct language + component in `scripts/data/integration_external_docs.yaml`:\n\n ```yaml\n - name: ClassOrDisplayName\n pypi: langchain-example # or npm: \"@org/pkg\" under javascript:\n docs_url: https://partner.example/docs\n ```\n\n Prefer the issue `docs_url` when it is an http(s) URL. Verify it returns a successful response when practical.\n\n3. Add a downloads-table row in the matching `src/snippets/oss/*-*-downloads.mdx` with a real `data-sort-value` (not `N/A` when a count is known). Match existing badge markup. For vectorstores/chat, map capability notes to the same ✅/❌ spans neighboring rows use.\n\n4. Add an alphabetical `all_providers` card in `src/oss/python/integrations/providers/all_providers.mdx` and/or the JS providers page when applicable. Use `icon=\"link\"` unless a provider icon already exists. For the card body, use issue `provider_description` after trimming whitespace. If that text is longer than **160 characters** (`PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`), rewrite it to one factual sentence of at most 160 characters before writing the card. Keep product and component names; drop marketing, feature lists, and second sentences. Do not invent capabilities that are not in the original text.\n\n5. Append `packages.yml` when there is a public LangChain-related package and public `owner/repo`. Ensure a trailing newline before appending. Omit `path: .`. Quote `js: \"n/a\"` when there is no JS package.\n\n6. Do **not** add `docs.json` nav entries or redirects for never-shipped pages.\n\n7. Do **not** hand-edit generated overview tables.\n\n8. Run `make lint_prose FILES=\"...\"` on changed MDX when prose changed.\n\n## Hosted guide checklist (≥50K)\n\n1. Copy the matching template under `src/oss/{python,javascript}/integrations//TEMPLATE.mdx`.\n2. Fill only with facts from the package README / partner docs / issue fields. Do not fabricate examples.\n3. Update component index / `docs.json` as other hosted pages do.\n4. Remove a duplicate external YAML row for the same package if present.\n\n## CI / handoff rules\n\n- Leave all changes **uncommitted** in the working tree unless the prompt explicitly says to commit.\n- Do **not** `git push` and do **not** open the PR yourself when running under GitHub Actions; the workflow opens the PR.\n- Do **not** comment on the GitHub issue or PR.\n- Write `integration-submission-error.md` only for hard blockers (see Decision style). Prefer completing a best-effort listing over failing.\n\n## Reference\n\n- External YAML: `scripts/data/integration_external_docs.yaml`\n- Downloads snippets: `src/snippets/oss/*-downloads.mdx`\n- Package registry: `packages.yml`\n- Related skill for converting existing PRs: `update-integrations-prs`\n",".agents/skills/verify-against-source/SKILL.md":"---\nname: verify-against-source\ndescription: Check that a code sample, API signature, default, or behavior claim in the docs is actually true, by running it or reading the product source. Covers which repository owns each product, how to reach the private ones, running the part of a sample that needs no API key, and what to say about a claim you could not verify. Use when writing or reviewing a page that asserts how LangChain, LangGraph, Deep Agents, or LangSmith behaves, and when a PR describes behavior without citing where it was checked.\n---\n\n# Verify a claim against the source\n\nThe failure this skill prevents: a page states a default, a precedence order, or\na field name that reads plausibly, passes Vale and the link checker, and is\nwrong. Nothing in CI checks whether a sentence about product behavior is true.\nA reviewer who knows the product catches some of it; the rest reaches readers.\n\nPublished docs, a README, and a model's recollection are all secondary sources.\nPrefer evidence you produced in this session.\n\n## Step 1. Pick the strongest evidence available\n\nWork down this list and stop at the first rung you can actually reach. Each rung\nis weaker than the one above it.\n\n- **Run the sample.** `make test-code-samples`, or scope it with\n `FILES=\"src/code-samples/langchain/foo.py\"`. This is the only method that\n proves a sample works end to end. It needs provider API keys in the\n environment, so it often fails locally and runs in CI instead.\n- **Run the half that needs no model.** Most claims are about a library's\n behavior, not the model's. Stand up the real object in a scratch script and\n print what it returns. A local MCP server, an adapter, a parser, or a store\n needs no API key, and the answer it gives is exact rather than inferred.\n- **Read the library source.** `gh api repos/langchain-ai//contents/\n --jq '.content' | base64 -d`, or `gh api \"search/code?q=+repo:langchain-ai/\"`\n to locate the file first. Settles what a type is, what a default is, and which\n branch actually runs.\n- **Check the installed package.** `uv run python -c \"from x import Y\"` confirms\n an import path resolves at the version this repo pins, which source on `main`\n cannot tell you.\n- **Look up the signature.** The `reference-langchain` MCP server exposes\n `search_api` and `get_symbol` over reference.langchain.com. Right for \"what\n are the parameters of X\", not for \"what does X do at runtime\".\n\n## Step 2. Know which repository owns the claim\n\n| Product | Repository | Where to look |\n|---------|------------|---------------|\n| LangChain | [langchain-ai/langchain](https://github.com/langchain-ai/langchain) | `libs/langchain_v1/langchain/` for v1, `libs/core/` for core, `libs/partners/` for provider packages |\n| LangGraph | [langchain-ai/langgraph](https://github.com/langchain-ai/langgraph) | `libs/langgraph/`, `libs/prebuilt/`, `libs/checkpoint*/`, `libs/cli/`, `libs/sdk-py/` and `libs/sdk-js/` |\n| Deep Agents | [langchain-ai/deepagents](https://github.com/langchain-ai/deepagents) | Also the source of the eval matrix the docs publish |\n| LangSmith SDK | [langchain-ai/langsmith-python](https://github.com/langchain-ai/langsmith-python) and [langchain-ai/langsmith-javascript](https://github.com/langchain-ai/langsmith-javascript) | The Python and JavaScript client libraries |\n| LangSmith platform | langchain-ai/langchainplus (private) | `smith-backend/` (Python API), `smith-go/` (Go services), `smith-frontend/` (UI labels and flows), `host-backend/`, `lc_config/` for settings and their defaults |\n| Agent Server | langchain-ai/langgraph-api (private) | Not in the OSS langgraph repo. Also the source of the Agent Server OpenAPI spec PRs |\n| Helm charts | [langchain-ai/helm](https://github.com/langchain-ai/helm) | `charts/langsmith/values.yaml` for defaults, `templates/_helpers.tpl` for the value-to-environment-variable mapping |\n| OpenEvals | [langchain-ai/openevals](https://github.com/langchain-ai/openevals) | Prebuilt evaluators |\n\nTwo traps worth naming:\n\n- **A private repo is still readable through `gh`.** `gh api` works on\n langchainplus and langgraph-api with the usual credentials. GitHub code search\n is unreliable on the larger ones, so fall back to the git trees API and fetch\n a path directly.\n- **langchain-ai/deployments is archived.** Its GitOps content moved into\n langchainplus. A skill, script, or note that still points at it is stale.\n\nA self-hosted LangSmith claim usually spans two repositories: the chart sets a\nvalue, and the backend decides what to do with it. Check both before describing\nprecedence, because the chart alone does not tell you which setting wins.\n\n## Step 3. Verify the claim, not the sentence\n\nRead the code path that produces the behavior, rather than a name that sounds\nlike it. Three failures that recur:\n\n- **A resolution order inferred from a settings table.** Find the query or the\n conditional that picks a value. An `ORDER BY`, a `COALESCE`, or an `or`\n expression is the precedence; a list of configurable fields is not.\n- **A defensive pattern copied from another sample.** Check whether the guarded\n case can occur. If the constructor only builds an object when a field is\n present, a `.get` with a default is documenting a state that never exists.\n- **A version or model identifier from memory.** Fetch it. The repository's own\n internal consensus is evidence about the repository, not about the provider.\n For model IDs specifically, see the Model references section of `AGENTS.md`.\n\n## Step 4. Record what you checked, and what you could not\n\nName the file and symbol in the pull request body, not just the conclusion. A\nreviewer can then disagree with the evidence rather than with an assertion.\n\nState the gaps in the same place. Common ones that no amount of source reading\ncloses:\n\n- **A UI string.** Source gives you a field and a component; only the running\n product gives you the rendered label. Describe the behavior rather than\n quoting a label you have not seen.\n- **The model-dependent half of a sample.** Say that CI has yet to run it.\n- **A beta surface.** `langchain.mcp` and similar namespaces can move under a\n page that was accurate when written.\n\nWriting \"not verified: the visible label of this control\" is a better outcome\nthan a confident sentence a reader discovers is wrong.\n\n## Related\n\n`AGENTS.md` holds the rules that apply to every edit, including never\nfabricating an example and testing code before publishing it. Use\n`docs-code-samples` when the claim belongs in a runnable sample rather than in\nprose, and `docs-review` for the style pass once the facts are settled.\n",".agents/skills/update-integrations-prs/SKILL.md":"---\nname: update-integrations-prs\ndescription: >-\n Process open LangChain docs integration PRs against the hosted-guide featuring\n policy (50K monthly downloads or maintainer feature override).

Inspect the current branch\n\n```bash\ngit branch --show-current\ngh pr view --json number,title,url,author,maintainerCanModify,files,body\ngit diff --stat upstream/main...HEAD\n```\n\nFind the LangChain-related package name(s) from `packages.yml`, MDX install snippets, or registry metadata. Ignore unrelated packages with similar names.\n\n### 2. Measure downloads\n\n**PyPI** (last ~30 days, no mirrors):\n\n```bash\ncurl -s \"https://pypistats.org/api/packages//overall?mirrors=false\" \\\n | python3 -c \"import sys,json; d=json.load(sys.stdin); data=d.get('data',[]); last30=data[-30:] if len(data)>=30 else data; print(sum(x.get('downloads',0) for x in last30))\"\ncurl -s \"https://pypistats.org/api/packages//recent\"\n```\n\n**npm** (last month):\n\n```bash\ncurl -s \"https://api.npmjs.org/downloads/point/last-month/\"\n```\n\nReport the number to the user before converting when they asked for downloads only.\n\n### 3. Rebase\n\n```bash\ngit fetch upstream main\ngit rebase upstream/main\n```\n\n- Keep contributor commits; put the conversion in a **new** commit after rebase.\n- On heavy merge history, cherry-pick content commits onto `upstream/main`, then convert.\n- Drop obsolete Card grids that main replaced with `IntegrationDownloads`.\n- Drop redirects for pages that were never on `main`.\n- Drop unrelated `packages.yml` download-count churn from bot commits.\n\n### 4a. External conversion (under 50K)\n\n1. **Delete** hosted MDX (component page and provider page if present).\n2. **Add YAML** under the correct language + component in `scripts/data/integration_external_docs.yaml`:\n\n ```yaml\n - name: ClassOrDisplayName\n pypi: langchain-example # or npm: \"@org/pkg\" under javascript:\n docs_url: https://partner.example/docs\n ```\n\n Prefer partner docs, then public GitHub/GitLab README, then PyPI/npm.\n3. **Downloads snippet** (sort by `data-sort-value`): add a row to the matching `src/snippets/oss/*-*-downloads.mdx` (for example `python-sandboxes-downloads.mdx`). Match existing badge markup.\n4. **`all_providers`**: card with external `href` (alphabetical). Use `icon=\"link\"` or an existing provider icon. Card body max **160 characters**. If a draft description is longer, shorten it to one factual sentence ≤160 characters; do not invent claims. Limit: `PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`.\n5. **`packages.yml`**: append only for a public LangChain-related package. Ensure a trailing newline before appending. Omit `path: .`. Skip if the source repo is private or not a normal public VCS listing.\n6. **Nav / redirects**: remove `docs.json` entries and redirects for deleted never-on-main pages. Do not add redirects for pages that never shipped.\n7. **Deep Agents / indexes**: if the PR added provider cards that main no longer uses, prefer downloads tables and index grids; keep brief mentions only when main already lists providers that way.\n\nAlign listings with **partner docs**, not stale PR page counts.\n\n### 4b. Hosted / featured path (≥50K or override)\n\n1. Keep (or fix) hosted MDX; test code examples when touching them.\n2. Frontmatter: follow templates under `src/oss/*/integrations/**/TEMPLATE.mdx`. Do not set `featured: true` unless a maintainer asked.\n3. Prefer `langchain` imports over `langchain_core` when editing kept pages.\n4. For featuring: set `highlight: true` in `packages.yml` only when asked; regenerate overview with the partner package table tool, do not hand-edit `overview.mdx`.\n5. Update `src/docs.json` if adding a page that should stay.\n\n### 5. Commit and handoff\n\n- Conversion commit message focuses on why (threshold / external listing / feature).\n- Show `git diff --stat upstream/main...HEAD` and downloads in the summary.\n- Note `maintainerCanModify` for push later.\n- **Do not push** unless the user asks. Use force-with-lease after rebase when pushing to the PR head.\n- If `maintainerCanModify: false`, say so and ask whether to open a replacement PR.\n\n## Hard rules\n\n- Ask for clarification rather than assuming package identity or feature overrides.\n- Never fabricate download counts, docs URLs, or package names.\n- Never edit `build/`.\n- Never hand-edit generated overview tables.\n- When appending to `packages.yml`, ensure a trailing newline first.\n- Run `make lint_prose FILES=\"...\"` on changed MDX before handoff when prose changed.\n- Follow repo git safety: no bare `git push`; no force to main; no commit unless asked (except when the user said \"go\" / \"next branch\" for this workflow, commit the conversion).\n\n## Common pitfalls\n\n| Pitfall | Fix |\n|---------|-----|\n| Wrong package (similar name on PyPI) | Confirm against install snippets and partner repo |\n| Re-adding Card grids removed on main | Use `IntegrationDownloads` / YAML only |\n| Redirects for never-shipped pages | Delete them |\n| Duplicate table rows | Remove YAML if keeping hosted page |\n| Private source repo | Skip incomplete `packages.yml` entry |\n| JS + Python packages | Add both

add-docs-page\ndescription: Add, move, rename, or delete a page on the LangChain docs site. Covers choosing the source directory, writing frontmatter, placing the entry in src/docs.json navigation, adding redirects, and verifying with the lint and broken-link gates. Use when asked to add a new doc or page, move or rename a page, put something in the nav, or add a redirect.\nlicense: MIT\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# Add or move a docs page\n\nA page is not finished when the MDX file exists. It also needs a navigation\nentry, and a move or deletion needs a redirect. CI enforces both.\n\nRead `AGENTS.md` for the navigation map, the style guide, and the frontmatter\nrules. This skill covers the procedure around them and does not repeat them.\n\n## Step 1. Choose the source directory\n\nUse the \"Source directory summary\" table in `AGENTS.md` to go from subject to\ndirectory. Two traps:\n\n- Directory names do not match navigation names. `src/langsmith/fleet/` appears\n as \"No-code agents\"; `src/langsmith/managed-deep-agents*.mdx` appears under\n Build, not under a LangSmith menu.\n- Lifecycle menus mix products. Build draws from both `src/oss/` and\n `src/langsmith/`; Test, Deploy, and Monitor all draw from `src/langsmith/`.\n\nNever write to `build/`. It is Mintlify output, regenerated by `make build`.\n\n## Step 2. Write the page\n\nRequired frontmatter:\n\n```yaml\n---\ntitle: Clear, concise page title\ndescription: SEO summary with no markdown, no links, and no backticks\n---\n```\n\nFor OSS pages that differ by language, use `:::python` and `:::js` fences in one\nfile rather than writing two files. The build pipeline emits both versions.\n\nTake every fact on the page from the product source, not from memory, a sibling\ndocs page, or the request that asked for the page. This covers behavior,\ndefaults, field names, version minimums, and examples. Use the\n`verify-against-source` skill to find the repository that owns each claim. Never\nfabricate a value to fill a gap. Leave the claim out, and list what you could\nnot confirm in the pull request body and in your reply to the requester.\n\n## Step 3. Add the navigation entry\n\nNavigation lives in `src/docs.json` under `navigation.products`. There are two\nproducts: `products[0]` is AGENT DEVELOPMENT LIFECYCLE (Home, Build, Test,\nDeploy, Monitor) and `products[1]` is PRODUCTS AND SETUP (LangSmith setup, LLM\nGateway, No-code agents, Engine, Deep Agents Code).\n\nEach menu item is addressed by its `item` key, then nests one of two ways:\n\n- `menu[].tabs[].pages[]` for most menu items.\n- `menu[].dropdowns[].tabs[].pages[]` for Build, which has Python and\n TypeScript dropdowns.\n\nA `pages` array holds page-path strings and `{\"group\": ..., \"pages\": [...]}`\nobjects, nested to any depth.\n\nThree rules:\n\n1. **A language-versioned OSS page needs two entries.** Build page paths carry\n the language segment (`oss/python/deepagents/overview` and\n `oss/javascript/deepagents/overview`), so one new page means one entry in the\n Python dropdown and one in the TypeScript dropdown. Omitting the TypeScript\n entry is the most common miss.\n2. **Page paths omit the `src/` prefix and the file extension.**\n `src/langsmith/sandboxes.mdx` is `\"langsmith/sandboxes\"`.\n3. **A new group leads with an index page:**\n `\"pages\": [\"group/index\", \"group/page\"]`.\n\nIntegration pages are the exception. Add them to the component's `index.mdx`\ninstead, and touch `docs.json` only when creating a brand-new component group.\n\n## Step 4. Add redirects for a move, rename, or deletion\n\nFor a move or rename of a file that was already on `main`, run the repo's mover first. It rewrites cross-references\nacross the corpus, which hand-editing misses: every link to the page in every\nform (`/oss/langchain/x`, `/oss/python/langchain/x`, `href=\"...\"`), plus the\n`src/docs.json` nav entries and redirect destinations that name it:\n\n```bash\nuv run docs mv src/langsmith/old-name.mdx src/langsmith/new-name.mdx --dry-run\n```\n\nRead any `Left ... links unchanged` warning in the output. It marks links the\nmover could not rewrite safely, such as an unversioned `/oss/integrations/...`\nlink that also reaches the other language's page. Fix those by hand.\n\nDrop `--dry-run` once the preview looks right. The mover does not add a\nredirect, so add one to the `redirects` array in `src/docs.json`:\n\n```json\n{ \"source\": \"/langsmith/old-name\", \"destination\": \"/langsmith/new-name\" }\n```\n\nRedirect paths are site paths and start with `/`. A language-versioned page\nneeds a redirect per language, plus one for the unversioned path if the old URL\nhad one.\n\n`scripts/check_removed_pages_redirects.py` runs in CI and fails the PR when a\npage leaves the navigation and its source file is gone with no redirect. The\nsame script fails when `docs.json` names a page whose file does not exist, so a\ntypo in a page path is caught there rather than at build time.\n\n## Step 4b. Two traps that fail silently\n\n### Extract a snippet once a block appears on three pages\n\n`AGENTS.md` covers how to add a snippet. The rule for **when**: the same block\nrepeated on three or more pages becomes one file under `src/snippets/`. A status\ncallout duplicated across a page family means the wording change that retires it\nis an edit to every page in the family, and one will be missed.\n\nVerify a new snippet reaches the build. The pipeline rewrites snippet imports to\nlanguage-specific paths, so `/snippets/langsmith/x.mdx` becomes\n`/snippets/python/langsmith/x.mdx` in the output, and a missing target renders as\nnothing at all rather than as an error:\n\n```bash\nls build/snippets/python/langsmith/.mdx build/snippets/javascript/langsmith/.mdx\n```\n\n### Editing a heading moves its anchor\n\nA heading's slug is derived from its text, so rewording one silently breaks every\n`#anchor` link pointing at it, including links from other pages and entries in\n`src/docs.json`. Grep before editing:\n\n```bash\ngrep -rn 'use-with-the-langsmith-gateway' src/ --include=*.mdx --include=*.json\n```\n\nChanging only capitalization is safe, because slugs are lowercased. Changing a\nword is not, and needs either a reworded inbound link or a redirect.\n`` and `` accept an explicit `id`, which is how to keep a\nlanding spot that is no longer a heading.\n\n## Step 5. Verify\n\nRun all three, in this order:\n\n```bash\nmake lint_prose FILES=\"src/path/to/page.mdx\"\nmake build\nmake broken-links-with-anchors\n```\n\nWhen `make build` fails with `Required uv version >=0.9.26 does not match the\nrunning version`, the local `uv` has drifted from the one `pyproject.toml`\nexpects. Run the pipeline directly rather than working around the build:\n\n```bash\nPYTHONPATH=\"$(pwd)\" .venv/bin/python -m pipeline build\n```\n\nA fresh git worktree has no `.venv`, and the same version check blocks\n`uv sync` from creating one. Point at the main checkout's interpreter instead;\n`PYTHONPATH` still loads the pipeline code from the worktree:\n\n```bash\nPYTHONPATH=\"$(pwd)\" /.venv/bin/python -m pipeline build\n```\n\nA fresh worktree's `.mise.toml` is also untrusted, so the first commit fails\nat the Vale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix.\n\n`make broken-links-with-anchors` depends on `build`, so it fails the same way.\nIts link-check half runs on its own once the build output exists:\n\n```bash\ncd build && mint broken-links --check-anchors | tee /tmp/bl.txt\ncd .. && python3 scripts/filter_mint_broken_links.py --check-anchors --input /tmp/bl.txt\n```\n\nRead `make broken-links-with-anchors` output by skipping to the `⎿` lines. Those are the only\nreal failures. A bare filename with no indented lines beneath it is an\nOpenAPI-generated page that exists at deploy time but not locally.\n\nFix every Vale finding. CI blocks on `lint_prose`, and its most common failure is\na spaced em dash (`word — word` must be `word—word`).\n\n## Step 6. Review the prose\n\nOnce the edit is complete and before committing, invoke the `docs-review` skill\non the files this pass changed. It runs in working-tree mode, so it needs no\ncheckout, and it covers the style-guide rules Vale cannot see: passive voice,\nfiller, product versus common noun capitalization, structure conventions, and\nlink text.\n\nRun it on finished edits only. A review of a half-written section produces\nfindings that go stale as soon as writing resumes.\n\nSkip this step for a change too small to have prose in it, such as a pure\n`docs.json` reorder or a redirect-only fix.\n\n## Step 7. Open the pull request\n\nFollow the `open-docs-pr` skill to commit, write the PR description, push, and\nwatch the checks. If the change belongs on an existing PR, use `docs-edit`\ninstead.\n\n## Checklist\n\n- [ ] File in the directory the source-directory table names, not `build/`.\n- [ ] Frontmatter present, `description` free of markdown.\n- [ ] Every claim checked against product source; unconfirmed claims cut and\n listed in the PR body.\n- [ ] `src/docs.json` entry in the right product, menu item, tab, and group.\n- [ ] Both language entries added if the page is language-versioned.\n- [ ] Index page first if a new group was created.\n- [ ] Redirect added for every moved, renamed, or deleted path.\n- [ ] Inbound `#anchor` links checked before any heading was reworded.\n- [ ] A block now on three or more pages extracted to `src/snippets/`, and its\n built `python/` and `javascript/` targets confirmed to exist.\n- [ ] `make lint_prose` clean, `make broken-links-with-anchors` shows no new `⎿` lines.\n- [ ] `docs-review` run on the changed files, findings addressed.\n- [ ] PR opened with `open-docs-pr`, checks green.\n",".agents/skills/docs-restructure/SKILL.md":"---\nname: docs-restructure\ndescription: Restructure documentation that spans several pages. Covers splitting a page that has grown too long, moving sections between pages, retiring a page, and fixing a topic documented in two places at once. Use when asked to streamline, simplify, consolidate, or reorganize docs, or when a page review keeps producing edits without the page getting shorter.\n---\n\n# Restructure docs across pages\n\nThe failure this skill prevents: an agent asked to \"streamline this page\" reorders\nits sections, collapses them into accordions, retitles them, and tabulates them,\nthirty times over, while the page gets longer. The page was never the problem.\nThree of its sections already existed on sibling pages.\n\nSingle-page skills cannot see that. `add-docs-page` owns one page's lifecycle and\n`docs-edit` owns one page's diff. This skill owns the question they cannot ask:\n**is this content on the right page at all?**\n\n`AGENTS.md` holds the navigation map, the style guide, and the frontmatter rules.\nThis skill covers the procedure around them and does not repeat them.\n\n## Step 1. Establish the page family\n\nA page almost never lives alone. Find its siblings before reading it closely:\n\n```bash\nls src/langsmith/llm-gateway*.mdx # a flat-file family\nls src/oss/deepagents/ # a directory family\ngrep -n '\"langsmith/llm-gateway' src/docs.json # what the nav groups together\n```\n\nThe nav grouping is the better signal when the two disagree: pages a reader\nmoves between are the pages whose content can be confused.\n\nThen list every heading in the family, so you are working from the whole shape\nrather than one file:\n\n```bash\ngrep -n '^## ' src/langsmith/llm-gateway*.mdx\n```\n\n## Step 2. Build a duplication map before writing anything\n\nThis is the step that does the work. For each H2 in the page you were asked to\nfix, search the rest of the family for the same content:\n\n```bash\ngrep -rn 'LANGSMITH_GATEWAY' src/langsmith/ --include=*.mdx\ngrep -rn 'Use a regional gateway' src/ --include=*.mdx\n```\n\nSearch for the distinctive noun, env var, or endpoint in the section, not for\nits heading. Duplicated content is usually retitled, which is why heading\nsearches miss it.\n\nRecord for each section: **does this topic already live somewhere else, and\nwhere?** Two copies that have drifted apart are the strongest finding available.\nIt means no page owns the topic, so both copies are edited independently and\nreaders get contradictions. In one real case the quickstart claimed TypeScript\nsupport for three providers while the sibling page said \"Python only.\"\n\nReport the map before editing anything. \"Three of these six sections duplicate\n`llm-gateway-api-formats`\" is the finding. The restructure is downstream of it.\n\n## Step 3. Assign one home per topic\n\nFor each topic in the map, pick the single page that should own it:\n\n- **Prefer a page that already exists.** A new page is warranted when the topic\n has no home and does not fit an existing one, not when it merely needs\n somewhere to go.\n- **Prefer the page a reader would search for**, not the page the content\n happens to sit on.\n- **Keep the most-linked URL.** Check before choosing, because inbound links\n decide which file survives a merge of two pages:\n\n ```bash\n grep -rn '(/langsmith/llm-gateway)' src/ --include=*.mdx | wc -l\n ```\n\n Folding content *into* the well-linked page and retiring the other one is\n usually cheaper than the reverse.\n\n## Step 4. Cut, do not relocate\n\nA section that duplicates a sibling gets **deleted** and replaced with one\nsentence pointing at the owner. It does not get moved, collapsed into an\naccordion, or shortened in place. An accordion still costs the reader the\ndecision of whether to open it.\n\nContent that has no home yet moves. Content that has one is already written.\n\nWhen you delete a section whose facts differ from the sibling's, the difference\nis a bug in one of them. Resolve it against the source before deleting, or you\nsilently pick a winner. See `docs-edit` for the verification procedure.\n\n## Step 5. Mechanics\n\nRetiring, renaming, or creating a page means navigation entries, redirects, and\ninbound links. `add-docs-page` covers all of it, including the anchor-stability\nand snippet traps. Follow it rather than improvising here.\n\nTwo additional things a restructure breaks that a single-page edit does not:\n\n- **Section anchors other pages link to.** Moving a section moves its anchor.\n Grep for `#the-anchor` across `src/` before the move and repoint every hit. A\n `` or `` can carry an explicit `id` to preserve a landing\n spot that is no longer a heading.\n- **Cross-page pointers that now point at the wrong page.** After moving a\n topic, the sibling pages that used to reference its old location need\n repointing, not just the page you edited.\n\n## Step 6. Verify\n\n```bash\nmake lint_prose FILES=\"\"\nmake build\nmake broken-links-with-anchors\npython3 scripts/check_removed_pages_redirects.py --base-ref origin/main src/docs.json\n```\n\nRead `broken-links-with-anchors` by skipping to the `⎿` lines; those are the\nonly real failures. Compare the count against the same command on `origin/main`\nso a pre-existing baseline is not read as a regression.\n\nThen review the prose with the `docs-review` skill, scoped to the files this\npass changed.\n\n## Step 7. Report what moved\n\nState, per page, what was **deleted**, what **moved**, and what was **added**,\nwith before and after line counts. A restructure that cannot show a page getting\nshorter has not restructured anything, and the line counts are what show the\nreviewer whether it did.\n\nName what you deleted rather than only what you wrote. A reviewer who asked for\na shorter page needs to see the cuts to agree with them.\n\n## Scope\n\nStay inside the page family named in the request. A restructure surfaces\nadjacent problems: stale model IDs, legacy version numbers, and the same\nduplication one directory over. Report them, and **ask before widening the\nsweep.** Fixing sixteen instances across a page family is a reasonable follow-on\ninside one pull request. Fixing six hundred across the corpus is a separate pull\nrequest and probably a tracked issue, because some instances are deliberate and\nsome live in generated files.\n\n## Checklist\n\n- [ ] Page family established from `src/docs.json`, not guessed from filenames.\n- [ ] Duplication map built and reported before any edit.\n- [ ] One owner chosen per topic; most-linked URL identified before merging pages.\n- [ ] Duplicated sections deleted and replaced with a pointer, not relocated.\n- [ ] Conflicting facts between copies resolved against source, not by picking one.\n- [ ] Redirects, nav entries, inbound links, and section anchors all updated.\n- [ ] Verification commands run, `⎿` count compared against `origin/main`.\n- [ ] Report gives per-page before and after line counts.\n- [ ] Anything outside the page family reported, not swept, unless asked.\n",".agents/skills/docs-code-samples/SKILL.md":"---\nname: docs-code-samples\ndescription: Use this skill when migrating inline code samples from LangChain docs (MDX files) into external, testable code files that are extracted by this repo’s snippet scripts and used as Mintlify snippets. Applies when extracting code blocks from documentation, creating runnable code samples, using snippet delineators, or wiring snippet output into MDX includes.\nlicense: MIT\ncompatibility: LangChain docs monorepo with Mintlify. Requires Python and Make (Node.js is also required for TypeScript samples).\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# docs-code-samples\n\n## Overview\n\nThis skill documents the workflow for moving inline code samples from LangChain documentation into standalone, testable files that this repo extracts into snippets for use in MDX using Mintlify.\n\n## When to use\n\n- Migrating inline Python, TypeScript/JavaScript, or Java code blocks from MDX to external files\n- Creating runnable, testable code samples for documentation\n- Setting up snippet extraction and Mintlify snippet includes\n\n## Directory structure\n\nCode samples live under `src/code-samples/` in folders that match the product:\n\n- `langchain/` — LangChain docs\n- `langgraph/` — LangGraph docs\n- `deepagents/` — Deep Agents docs\n- `langsmith/` — LangSmith docs\n\nExample:\n\n```\nsrc/\n├── code-samples/ # Source: testable code with snippet tags\n│ ├── langchain/\n│ │ ├── return-a-string.py\n│ │ └── return-a-string.ts\n│ ├── langgraph/\n│ │ ├── langgraph-sql-agent.py\n│ │ └── langgraph-sql-agent.ts\n│ ├── deepagents/\n│ │ └── example-skill.py\n│ └── langsmith/\n│ ├── trace-example.py\n│ └── trace-example.java\n├── code-samples-generated/ # Snippet output (gitignored)\n│ ├── return-a-string.snippet.tool-return-values.py\n│ ├── return-a-string.snippet.tool-return-values.ts\n│ └── ...\n└── snippets/\n └── code-samples/ # MDX snippets for docs (all products)\n ├── tool-return-values-py.mdx\n ├── tool-return-values-js.mdx\n └── ...\n```\n\n**Prefer one file per doc page or topic**: Collocate related snippets in a single code sample file whenever they belong to the same MDX page, tutorial flow, or feature (for example, setup plus invocation, or a do/don't pair). Use multiple `:snippet-start:` / `:snippet-end:` pairs in that file rather than splitting into several `.py` or `.ts` files. Reserve separate files for unrelated samples or when a page genuinely needs independent test entry points.\n\n**More than one snippet in one file**: A single code sample file can contain more than one named snippet using different `:snippet-start: snippet-name` and `:snippet-end:` pairs. Each snippet must have a unique name. Shared imports, helpers, and `:remove-start:` test harness code live once in the file; only the fenced regions between snippet tags appear in the generated MDX snippets.\n\n**When to split TypeScript samples into separate files**: Python samples can usually keep multiple snippets in one file because later definitions overwrite earlier ones at module scope. TypeScript and JavaScript cannot: `make test-code-samples` runs the entire `.ts` file, and every snippet's code executes in the same module scope. Split into separate `.ts` files when snippets would collide, for example:\n\n- Duplicate `import` bindings (for example two snippets both `import { interrupt } from \"@langchain/langgraph\"`)\n- Duplicate `const` / `let` / `class` / `function` declarations with the same name (for example two snippets both declare `const State = ...`)\n- Two self-contained snippets that each need their own imports and top-level setup\n\nKeep related snippets in one Python file when possible. For TypeScript, use one file per independently runnable snippet when imports or top-level bindings would conflict. Name sibling files clearly, for example `langgraph-interrupts-validate-conditional-edge-pattern.ts` and `langgraph-interrupts-validate-conditional-edge.ts`. Put shared test-only setup in `:remove-start:` blocks inside each file rather than importing between sample files.\n\nWithin a single TypeScript file, `:remove-start:` blocks and snippet regions share the same module scope when `make test-code-samples` runs the file. Do not import the same binding in both places. Keep imports that appear in the docs snippet inside the snippet; limit `:remove-start:` imports to symbols used only by the test harness (for example `Command`, `MemorySaver`) that the snippet does not import.\n\n## Step-by-step instructions\n\n### 1. Create the code sample file\n\nPlace the file under `src/code-samples/` in the folder for the product: `langchain/`, `langgraph/`, `deepagents/`, or `langsmith/` (for example, `src/code-samples/langgraph/langgraph-sql-agent.py` for LangGraph docs).\n\nUse a descriptive filename, for example, `return-a-string.py`, `return-a-string.ts`, or `traceable-pipeline.java`. When a doc page needs several code blocks for the same feature, add them as multiple snippets in one Python file (for example, `rubric-configure.py` with `rubric-configure-py` and `rubric-invoke-py`) instead of creating `rubric-configure.py` and `rubric-invoke.py`. For TypeScript, use one file per snippet when module-scope imports or bindings would conflict (see **When to split TypeScript samples into separate files** above).\n\n### 2. Add snippet delineators\n\nWrap the code that should appear in the docs with snippet tags:\n\n**Python:**\n```python\n# :snippet-start: snippet-name-py\nfrom langchain.tools import tool\n\n@tool\ndef get_weather(city: str) -> str:\n \"\"\"Get weather for a city.\"\"\"\n return f\"It is currently sunny in {city}.\"\n\n# :snippet-end:\n```\n\n**TypeScript/JavaScript:**\n```ts\n// :snippet-start: snippet-name-js\nimport { tool } from \"langchain\";\n// ... tool definition ...\n// :snippet-end:\n```\n\n**Java:**\n```java\n// :snippet-start: snippet-name-java\npublic class Example {\n public static void main(String[] args) {\n System.out.println(\"hello\");\n }\n}\n// :snippet-end:\n```\n\n**Go:**\n```go\n// :snippet-start: snippet-name-go\npackage main\n\nimport \"fmt\"\n\nfunc main() {\n\tfmt.Println(\"hello\")\n}\n// :snippet-end:\n```\n\n**Bash (cURL):**\n```bash\n# :snippet-start: snippet-name-sh\ncurl \"https://api.smith.langchain.com/api/v1/runs\" \\\n -H \"x-api-key: $LANGSMITH_API_KEY\"\n# :snippet-end:\n```\n\nChoose a unique `snippet-name` in kebab-case. All snippet names must include a language suffix: `-py` for Python files, `-js` for TypeScript/JavaScript files, `-java` for Java files, `-kt` for Kotlin files, `-go` for Go files, and `-sh` for bash/cURL files (for example, `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh`). This becomes the base of the output filename.\n\n### 3. Add runnable test code in remove blocks\n\nWrap any code that makes the sample executable but should not appear in docs.\n\n**Run snippet code before exiting.** `make test-code-samples` must execute the snippet body, not skip it. Do not put `raise SystemExit(0)`, `process.exit(0)`, or `exit 0` at the top of a file (or before `:snippet-start:`) so the test passes without running imports, constructors, or API calls. That only checks that the file parses; it does not validate function signatures, option shapes, or import paths.\n\nPlace `:remove-start:` blocks **after** the snippet when you can, so the harness runs assertions on values the snippet created:\n\n**Python (preferred):**\n```python\n# :snippet-start: example-py\nfrom deepagents import create_deep_agent\n\nagent = create_deep_agent(model=\"google_genai:gemini-3.6-flash\")\n# :snippet-end:\n\n# :remove-start:\nassert agent is not None\nprint(\"✓ example validated\")\n# :remove-end:\n```\n\n**TypeScript (preferred):**\n```ts\n// :snippet-start: example-js\nimport { DeepAgentsServer } from \"deepagents-acp\";\n\nconst server = new DeepAgentsServer({\n agents: { name: \"careful-agent\", interruptOn: { write_file: true } },\n});\n// :snippet-end:\n\n// :remove-start:\nif (!server) throw new Error(\"server not created\");\nconsole.log(\"✓ example validated\");\n// :remove-end:\n```\n\nFor samples whose docs show a blocking tail (for example `await server.start()`, `asyncio.run(main())`, or `agent.invoke()` with a live model), keep setup and construction in the snippet so types and signatures are checked, then move **only** the blocking call into a trailing `:remove-start:` block—or omit it when construction alone is enough:\n\n```python\n# :snippet-start: server-example-py\nserver = AgentServerACP(agent)\n# :snippet-end:\n\n# :remove-start:\n# Do not call await run_agent(server) here — it blocks on stdio.\nassert server is not None\nprint(\"✓ server-example validated\")\n# :remove-end:\n```\n\n**Do not** short-circuit before the snippet:\n\n```python\n# :remove-start:\nraise SystemExit(0) # BAD: snippet below never runs\n# :remove-end:\n\n# :snippet-start: example-py\n...\n```\n\nThe examples below show harness code that invokes behavior when the snippet defines callable helpers:\n\n**Python:**\n```python\n# :remove-start:\nif __name__ == \"__main__\":\n result = get_weather.invoke({\"city\": \"San Francisco\"})\n assert result == \"It is currently sunny in San Francisco.\"\n print(\"✓ Tool works as expected\")\n# :remove-end:\n```\n\n**TypeScript:**\n```ts\n// :remove-start:\nasync function main() {\n const result = await getWeather.invoke({ city: \"San Francisco\" });\n if (result !== \"It is currently sunny in San Francisco.\") {\n throw new Error(`Expected \"...\", got \"${result}\"`);\n }\n console.log(\"✓ Tool works as expected\");\n}\nmain();\n// :remove-end:\n```\n\nThe extraction script strips `:remove-start:` / `:remove-end:` content when extracting snippets.\n\n### 4. Test the code sample\n\nBefore extracting snippets, verify the code sample runs correctly:\n\n```bash\n# Test the file(s) you added (faster)\nmake test-code-samples FILES=\"src/code-samples/langchain/return-a-string.py\"\n\n# Or run all code samples\nmake test-code-samples\n```\n\nFor multiple files: `FILES=\"path1 path2\"`. Fix any failures before proceeding—do not extract snippets until the samples pass.\n\nTo run one product's samples, set `CODE_SAMPLE_PATHS` to space-separated directories under `src/code-samples/`, for example `CODE_SAMPLE_PATHS=\"src/code-samples/langsmith\" make test-code-samples`. It also narrows an explicit `FILES` list. CI runs one matrix leg per product this way (`oss` covers `langchain/`, `langgraph/`, and `deepagents/`; `langsmith` covers `langsmith/`), so a failure in one product never turns the other product's check red. A new top-level directory under `src/code-samples/` must be added to a leg in `.github/workflows/test-code-samples.yml`, or the workflow fails its coverage check.\n\nJava files (`.java`) under `src/code-samples/` are run using `jbang`. To keep CI green, Java samples must:\n\n- Print at least one line of output so it's obvious the sample ran\n- Exit successfully (code 0) when optional API keys are not set, for example:\n - `OPENAI_API_KEY` for LLM calls\n- Fail fast (non-zero exit) when a key is required for the sample to run, for example `manage-prompts-0-push.java` without `LANGSMITH_API_KEY`\n\n`make test-code-samples` runs every `.java` file under `src/code-samples/` in **lexical path order** (after all Python and TypeScript samples). That order is unrelated to section order in the docs. If one sample must run before another (for example creating a hub prompt before pulling it), name the source files so they sort correctly. For example, `manage-prompts-pull.java` runs before `manage-prompts-push.java` because `pull` sorts before `push`; use prefixes such as `manage-prompts-0-push.java` and `manage-prompts-1-pull.java` when you need push to run first.\n\nGo files (`.go`) under `src/code-samples/` are run with `go run` from `src/code-samples/`, which shares a single `go.mod`/`go.sum` at that directory (add new dependencies there with `go get`, then `go mod tidy`, similar to how `.ts` samples share `src/code-samples/package.json`). `go run .go` only compiles that one file, not its sibling files in the same directory, so — like Kotlin — put each snippet variant in its own file (`topic-before.go`, `topic-after.go`) rather than multiple snippets sharing one file: two files in the same package cannot both declare `func main()`. Go samples do not guard on missing keys — let the SDK call fail fast (matching Python's behavior) rather than skipping with a printed message. `make test-code-samples` runs `.go` files last, after Kotlin, in lexical path order.\n\nBash/cURL files (`.sh`) under `src/code-samples/` are run with `bash .sh` from `src/code-samples/`. Like Go, put each snippet variant in its own file (`topic-before.sh`, `topic-after.sh`) rather than sharing one file. Hide test-only setup (`#!/usr/bin/env bash`, `set -euo pipefail`, resolving a real ID/value for a `` shown in the docs) in `# :remove-start:`/`# :remove-end:` blocks so the visible snippet is exactly the illustrative curl command a reader would copy — including no shebang or `set -e` line. `curl` does not exit non-zero on an HTTP error status by itself, so when a script pipes a response into `jq` to extract a value used by a later request (for example resolving a project ID), add a hidden check that the resolved value is non-empty and not the literal string `null` before continuing, so a bad API response fails the test loudly instead of silently propagating into later requests. `make test-code-samples` runs `.sh` files last, after Go, in lexical path order.\n\nCheck formatting with:\n\n```bash\nmake lint\n```\n\nFix any ruff or mypy issues before proceeding. Run `make format` to auto-fix formatting.\n\n### 5. Run snippet extraction\n\nFrom the repo root:\n\n```bash\nmake code-snippets\n```\n\nTo limit extraction to specific samples (faster while iterating), set `CODE_SNIPPET_SOURCES` to space-separated repo-relative paths under `src/code-samples/`:\n\n```bash\nCODE_SNIPPET_SOURCES=\"src/code-samples/langsmith/trace.java\" make code-snippets\n```\n\nThis command:\n\n1. Runs `python scripts/extract_code_snippets.py` (line-based, Bluehawk-compatible; handles `/**` in TS strings). Optional env `CODE_SNIPPET_SOURCES` limits extraction to specific paths under `src/code-samples/`; other stems already in `src/code-samples-generated/` are left alone.\n2. Runs `scripts/generate_code_snippet_mdx.py` to produce MDX snippets in `src/snippets/code-samples/` (always regenerates MDX from everything under `src/code-samples-generated/`)\n\nOutput files:\n\n- `return-a-string.snippet.tool-return-values.py` → `tool-return-values-py.mdx`\n- `return-a-string.snippet.tool-return-values.ts` → `tool-return-values-js.mdx`\n\n### 6. Update the MDX file to use the snippet\n\nAdd an import at the top of the MDX file (after frontmatter):\n\n```mdx\nimport ToolReturnValuesPy from '/snippets/code-samples/tool-return-values-py.mdx';\nimport ToolReturnValuesJs from '/snippets/code-samples/tool-return-values-js.mdx';\n```\n\nReplace the inline code blocks with the snippet components:\n\n```mdx\n:::python\n\n\n\n:::\n\n:::js\n\n\n\n:::\n```\n\n## Naming conventions\n\n| Element | Convention | Example |\n|--------|-------------|---------|\n| Code file | Descriptive, kebab-case | `return-a-string.py`, `return-a-string.ts`, `traceable-pipeline.java`, `traceable-pipeline.kt`, `traceable-pipeline.go`, `traceable-pipeline.sh` |\n| Snippet name | Kebab-case with language suffix: `-py` for Python, `-js` for JS/TS, `-java` for Java, `-kt` for Kotlin, `-go` for Go, `-sh` for bash/cURL | `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh` |\n| MDX snippet (Python) | `{snippet-name}.mdx` (snippet name ends in `-py`) | `tool-return-values-py.mdx` |\n| MDX snippet (JS) | `{snippet-name}.mdx` (snippet name ends in `-js`) | `tool-return-values-js.mdx` |\n| Component name | PascalCase | `ToolReturnValuesPy`, `ToolReturnValuesJs` |\n\n## Script behavior\n\n`scripts/generate_code_snippet_mdx.py`:\n\n- Reads `*.snippet.*.py` and `*.snippet.*.ts` from `src/code-samples-generated/`\n- Wraps content in fenced code blocks (`` ```python `` or `` ```ts ``)\n- When a snippet contains a model string, expands it into a Mintlify `` with the seven quickstart provider tabs (Google, OpenAI, Anthropic, OpenRouter, Fireworks, Baseten, Ollama):\n - Python: `model=\"…\"` or `model = \"…\"`\n - TypeScript: `model: \"…\"` or `model = \"…\"` (including `let model = \"…\"`)\n - Only the quoted model ID is swapped per tab, so assignment vs property syntax is preserved\n - Put `# KEEP MODEL` / `// KEEP MODEL` on the line before a model string to leave that occurrence unchanged\n- Writes to `src/snippets/code-samples/{snippet-name}-py.mdx` or `-js.mdx`\n\nTo support additional languages, add config entries in that script.\n\n## Guidelines\n\n- **Prefer the plainest thing that runs.** Keep the snippet verbatim from the page, add hidden harness code only where CI differs from a reader's machine (a missing env var, a dataset name that must be cleared first), and do not add options, inputs, or indirection nobody asked for. The same applies to the runner and workflow around the samples: one job per product, re-run a job from the GitHub UI rather than adding an input for it, read what GitHub already knows (job names, conclusions) rather than passing artifacts around. If a change needs a diagram to explain, it is too much.\n- **Run snippet code in tests** — `:remove-start:` harnesses must not exit before the snippet runs. Let imports, constructors, and configuration execute so `make test-code-samples` catches wrong signatures, renamed options, and broken import paths. Put `SystemExit` / `process.exit` only after the snippet (or use them to skip a trailing blocking call such as `server.start()`, not the whole sample).\n- **Collocate related snippets** in one code sample file per doc page or feature when possible (Python and Java). Import each generated MDX snippet separately in the MDX file (for example, `` then `` from the same source file). For TypeScript, split into separate `.ts` files when snippets duplicate imports or top-level bindings; still import each generated MDX snippet in the MDX file the same way.\n- Do not mock LangChain internals (for example `unittest.mock.patch` on `init_chat_model` helpers) so that imports resolve real chat model instances. Do not use fake chat models in docs code samples (for example `GenericFakeChatModel`, `FakeListChatModel`, or other `langchain_core` testing fakes). Wire a real chat model (for example `ChatOpenAI`) so snippets match what readers run; `make test-code-samples` requires a valid API key when the sample calls the model.\n- Do not change `pyproject.toml` when making code sample changes.\n- Always run `make test-code-samples FILES=\"path/to/your/file.py\"` before `make code-snippets` to ensure new samples pass.\n- Run `make lint` once the code sample is written; fix any issues (or run `make format` to auto-fix).\n- Do not add code samples to linting ignore rules when making lint-related changes—fix the code instead.\n- `src/code-samples-generated/` is gitignored; regenerate with `make code-snippets`, narrowing to specific files with `CODE_SNIPPET_SOURCES` while iterating.\n- Reference `AGENTS.md` for docs style and rules.\n- Use `:::python` and `:::js` fences for language-specific content; the build produces separate Python and JavaScript doc versions.\n- For python tests, try to correct the type rather than adding `# type: ignore[arg-type]`\n",".agents/skills/docs-team-voice/SKILL.md":"---\nname: docs-team-voice\ndescription: Write or revise documentation prose so it reads like the rest of this site, in the docs team's shared voice. Covers sentence length, cross-link density, how to state defaults and conditions, naming exact identifiers, and what to cut in a revision pass. Use when drafting or rewriting a page, a section, a concept overview, a how-to, a callout, or landing copy.\n---\n\n# Write in the house voice\n\n`AGENTS.md` holds the rules a linter can check: no contractions, no first\nperson, no future tense, sentence-case headings, Oxford commas, spacing around\ndashes. Vale enforces most of them and `make lint_prose` is the gate, though\nVale does not scan inside JSX components such as `` and ``, so a\nclean run there proves nothing. This skill covers what a linter cannot check:\nrhythm, density, and the shape of a sentence that carries information.\n\nThe targets below are measured from this repository's own pages, not invented.\n\n## Keep sentences short\n\nMedian sentence length on this site is **13 to 15 words**. Roughly one sentence\nin twelve runs past 25 words, one in forty past 30. Treat 25 as the point where\nyou look for a split and 35 as a defect.\n\nOne idea per sentence. When a sentence carries two, split it and let the second\nstand alone.\n\n> The agent definition selects the model and core capabilities of a managed deep\n> agent.\n\n> Set the `compression` field to control how exported Parquet files are\n> compressed. When omitted, LangSmith uses `zstandard`.\n\nThe second example is two sentences where one long one would have hidden the\ndefault inside a subordinate clause.\n\nThe target is a floor as well as a ceiling. Keep the condition, the actor, and\nthe exact value even when they push a sentence long, and split it rather than\ndropping one of them to get under 15 words.\n\n## Link about half the time\n\nClose to half of all prose sentences here carry a link. Cross-linking is not\ndecoration: it is how a reader escapes a page that does not answer the question\nthey arrived with.\n\nLink a term on first mention only. Pointing forward at the end of a section is\nstandard, and **two pointer forms are both established**:\n\n> Refer to [Spend policies](/langsmith/llm-gateway-spend-policies).\n\n> For the full project layout, see [Project\n> structure](/langsmith/managed-deep-agents-project-structure).\n\nNeither is canonical. Different authors favor different ones, so match the form\nthe page already uses and do not mass-convert one into the other.\n\n## State defaults and conditions as bare facts\n\nPut the trigger first, then the behavior. No hedging, no \"please note\".\n\n> When omitted, LangSmith uses `zstandard`.\n\n> Defaults to the last 7 days, newest first.\n\n> Task planning is opt-in.\n\n> Non-zero exits and timeouts from `--startup-cmd` warn but do not abort the\n> session.\n\nConstraints read the same way, as plain statements of fact rather than warnings\nabout them.\n\n## Name the exact identifier\n\nBacktick every field, flag, value, environment variable, and status. Between a\nquarter and a half of prose sentences on this site contain one. Name the actual\nvalue rather than gesturing at it: `zstandard`, not \"the appropriate\ncompression\"; `CREATED`, `RUNNING`, `COMPLETED`, not \"the various statuses\".\n\n> If your API key is linked to multiple workspaces, specify the workspace in the\n> header with `\"x-tenant-id\"`.\n\n## Reach for a concrete example early\n\n\"For example\" appears in roughly one sentence in thirty, almost always followed\nby a real value rather than a shape.\n\n> For example, in SCIM, the resolved `sub` claim and SCIM `externalId` must\n> match in order for login to succeed.\n\nIf you cannot supply a real example, say less rather than inventing one. Never\nfabricate a field name, a response body, or a policy detail to fill a slot.\n\n## Address the reader, and prefer the active voice\n\nSecond person carries a quarter to a half of sentences, most heavily in\nprocedures and UI steps. Passive voice appears in only about one sentence in\neight, and usually where the actor genuinely does not matter.\n\n> When viewing a trace that was generated by a run in LangSmith, you can access\n> the associated server logs directly from the Details view.\n\nUse the product name as the subject when the reader is not the actor: \"LangSmith\nuses `zstandard`\", not \"we use `zstandard`\".\n\n## Revision pass\n\nRead the draft once looking only for these:\n\n- **Sentences over 25 words.** Split, or cut a clause.\n- **Hedges and filler.** \"simply\", \"just\", \"very\", \"basically\", \"note that\",\n \"be sure to\", \"in order to\", \"has the ability to\". These are near-absent from\n this site's prose, well under one percent of sentences. Delete or replace.\n- **A spaced em dash.** `word — word` fails `LangChain.DashesSpaces` and blocks\n CI. Prefer a comma, a colon, or two sentences, and reach for `word—word` only\n when nothing else reads. A bold label opening a paragraph takes a colon:\n `**Tier assignment**:`, measured at 177 uses in `src/` against 1 for the dash.\n- **A vague identifier** where the exact one belongs.\n- **A cut that took a fact with it.** A tightened sentence that lost its\n condition, its actor, or its exact value reads cleanly and says something\n else. Restore the fact and split the sentence.\n- **A first mention with no link**, and repeat mentions that are linked again.\n- **A claim you did not verify.** Check it against the product source with the\n `verify-against-source` skill, or cut it. Another docs page is not a source.\n Name every claim you could not confirm in the PR body.\n- **A fact that disagrees with a related page.** Grep `src/` for the feature and\n read the pages that cover it from another angle, such as a CLI reference or a\n permissions table. The `docs-edit` skill covers what to look for.\n- **An added \"key features\" list, or a horizontal rule** used to separate\n sections. Neither belongs here.\n\nThen run the gate:\n\n```bash\nmake lint_prose FILES=\"\"\n```\n\nFor a full review against the style guide, with the rule each finding breaks,\nuse the `docs-review` skill.\n",".agents/skills/docs-edit/SKILL.md":"---\nname: docs-edit\ndescription: Edit a docs page that already has an open pull request, or revise a page in place. Covers checking out the PR's own branch instead of cutting a new one, forked cross-repository PRs, reading the real diff, checking the edit against related pages, and the verification to run before handing off. Use when asked to edit, revise, fix, or review changes on a named PR, branch, or existing page.\n---\n\n# Edit an existing docs page or PR\n\nThe failure this skill prevents: an agent asked to \"fix the wording on PR 1234\"\ncuts a fresh branch, commits there, and opens a second pull request against a\nteammate's work. Land edits on the branch that already exists.\n\n## Step 1. Check out the PR's own branch\n\nWhen the request names a PR, by number or URL, work on that PR's head branch.\n\n```bash\ngh pr view --json number,title,headRefName,baseRefName,author,isCrossRepository,files\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse plain `git checkout `. Do not use `git checkout -b` or `--no-track`:\neach produces a net-new branch, and committing there opens a second PR against\nsomeone else's work.\n\nA worktree on the PR's own branch is fine, and safer when other sessions share\nthe main checkout. Pass the existing branch name, never `-b`:\n\n```bash\ngit fetch origin \ngit worktree add # tracks origin/\n```\n\nThis fails if the branch is already checked out in another worktree. Use that\nworktree instead of forcing a second one.\n\nmise trusts config files by path, so each new worktree's `.mise.toml` starts\nout untrusted. The Vale pre-commit hook runs through `mise exec`, and the first\ncommit fails with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree, then commit again. To stop this\nfor good, add the main checkout to `trusted_config_paths` in\n`~/.config/mise/config.toml`. It trusts every worktree created inside the\ncheckout, such as `.claude/worktrees/*`, but not sibling directories.\n\nA local branch whose name merely mentions the PR is not the same branch. Confirm\nthat `git rev-parse HEAD` matches the `headRefOid` from `gh pr view` before\nediting, and that the branch has an upstream:\n\n```bash\ngit rev-parse --abbrev-ref @{upstream} # fails when the branch tracks nothing\n```\n\nCut a new branch only when the edits are your own and no open PR exists to land\nthem on, or when the user asks for one. Branch from the latest `origin/main`,\nnever from a stale local `main`.\n\n### Cross-repository PRs\n\nWhen `isCrossRepository` is `true`, the branch lives on a fork. Use `gh pr\ncheckout `, which configures the fork remote, and confirm push access before\ncommitting. Without it, the edits are stranded locally.\n\n## Step 2. Read the real diff\n\n```bash\ngh pr diff \n```\n\nPrefer this over `git diff main...HEAD`. A stale local `main` silently inflates\nthat diff with unrelated commits, and a branch that already merged `main` once\ninflates it further. To compare against the live base instead, fetch first and\nuse `git diff origin/main...HEAD`.\n\n## Step 3. Edit\n\n`AGENTS.md` holds the rules that apply to every edit: the style guide,\nfrontmatter, syntax, and the navigation map. Two that matter most here:\n\n- Match the conventions of the file you are editing. Do not restructure,\n combine, or split pages unless asked.\n- Never fabricate examples, field names, UI labels, or policy details. Verify\n each factual claim against the source it describes, and state plainly what you\n could not verify.\n\nFor voice and sentence rhythm while drafting, use the `docs-team-voice` skill. For\nadding, moving, renaming, or deleting a page, including navigation and\nredirects, use `add-docs-page`. When the edit is really a question of which page\nthe content belongs on, use `docs-restructure`.\n\n### Verify claims against source, not against other docs\n\nA sibling docs page is not a source. It is another claim, written by someone who\nmay have been guessing too, and two docs pages that agree can both be wrong.\nCheck the implementation:\n\n```bash\ngh api -X GET search/code -f q='LANGSMITH_GATEWAY repo:langchain-ai/langchain' \\\n --jq '.total_count, (.items[]?|.path)'\ngh api repos/langchain-ai/langchain/contents/ --jq .content | base64 -d\n```\n\nPython and TypeScript live in separate repositories and drift apart, so a table\nwith a Python column and a TypeScript column needs both checked:\n`langchain-ai/langchain`, `langchain-ai/langchainjs`, and for some providers a\ndedicated repository such as `langchain-ai/langchain-google`. A package's\n`CHANGELOG.md` gives the version a feature landed in, which is what a minimum\nversion column needs.\n\nState plainly what you could not verify. \"I could not confirm the Baseten row;\nno gateway references in either candidate repository\" is a useful review note.\nSilently keeping an unverified claim is not.\n\n### Read the pages around the one you are editing\n\nA page is one of several that cover the same feature. Others reach it from\nanother angle: a CLI reference, a permissions table, a list of Chat surfaces, a\nsetup guide, the pages that link to it. An edit made to one page in isolation\nleaves the set contradicting itself.\n\nBefore editing, find the related pages:\n\n```bash\ngrep -rliE \"|\" src --include='*.mdx'\ngrep -n \"\" src/docs.json\n```\n\nRead each one, then check for:\n\n- **Contradictions.** The edited page and a related one give different setup\n steps, defaults, or requirements. For example, a feature page that sets\n `LANGSMITH_API_KEY` while the CLI page recommends `langsmith auth login`.\n Settle it against source, then fix whichever page is wrong.\n- **Duplication.** A procedure the edited page restates from the page that owns\n it. Link to the owner instead. When choosing the owner is the real question,\n use `docs-restructure`.\n- **Missing entry points.** A page that lists every surface, command group, or\n permission area of a product should mention the feature and link to it.\n- **Navigation placement.** A page filed in a group that does not match its\n subject. Report it; do not move the page unless asked.\n\nA related page tells you what to check, not what is true. When two pages\ndisagree, the source decides, as described in the section above.\n\nKeep edits to related pages small: a cross-link, a corrected fact, or a short\nentry that points at the owner page. Anything larger is a restructure, so ask\nfirst.\n\n### Never hand-edit generated files\n\nThese are written by a generator. Editing them looks like it works, then a\nscheduled run reverts it, and for the changelogs the edit has already gone out\nover RSS:\n\n| File | Generated by |\n|------|--------------|\n| `src/langsmith/changelog.mdx` and `src/snippets/langsmith/fleet-changelog.mdx` | the `changelog-weekly.yml` workflow (`scripts/changelog_pipeline.py weekly`), from merged langchainplus PRs |\n| `src/langsmith/self-hosted-changelog.mdx` | the helm changelog bot |\n| `src/langsmith/langsmith-platform-openapi.json` | `.github/workflows/refresh-langsmith-openapi.yml` |\n| `src/langsmith/agent-server-openapi.json` | PRs from the `langgraph-api` repository |\n| `src/snippets/deepagents-eval-category-matrix.mdx` | `scripts/refresh_deepagents_category_matrix.py` |\n| `src/snippets/langsmith/mda-oauth-catalog.mdx` | `scripts/refresh_mda_oauth_catalog.py` |\n| `build/` | `make build` |\n\nWhen one of these carries the problem you were asked to fix, fix the generator\nor the upstream source and say so. Do not edit the output.\n\n### When an instruction reverses an earlier one\n\nReviewers change their minds, and on a long thread they will ask for a format\nthey previously rejected. Converting a table to a list and then back wastes a\nround and loses the reasoning both times.\n\nWhen an instruction contradicts one you already applied, say so before applying\nit: name the earlier instruction, the change you made for it, and ask which to\nkeep. Two reversals on the same element mean the requirement is unclear, not\nthat the format is wrong.\n\n## Step 4. Verify before handing off\n\n```bash\nmake lint_prose FILES=\"\"\n```\n\nRun `make broken-links-with-anchors` as well when links, page names, or navigation entries\nchanged. For a prose review against the style guide, use the `docs-review`\nskill.\n\n## Step 5. Report\n\nSay which branch the edits are on and whether it is the PR's own branch. Name\nthe related pages you changed, and the ones you read and left alone. If\nanything could not be verified, list it. Do not push or force-push unless the\nuser asks. When the user asks you to push, the merge-state check and the check\nwatching in `open-docs-pr` apply here too. When the edits have no PR to land\non, open one with `open-docs-pr`.\n",".agents/skills/docs-review/SKILL.md":"---\nname: docs-review\ndescription: Review changed docs prose against Vale and the AGENTS.md style guide, reporting findings with the rule each one breaks.

Do not stretch a rule to reach a finding, and do not restructure\n prose that is already fine.\n\n## Step 1. Resolve the target\n\nRun `git fetch origin` first so `main` is current. Resolve in this order:\n\n1. **A number or GitHub PR URL** means a PR. Get the branch with\n `gh pr view --json headRefName`.\n2. **A branch name** is used directly.\n3. **Empty, with uncommitted changes present** means the working tree. Take the\n files from `git status --porcelain` plus\n `git diff --name-only --diff-filter=d origin/main...HEAD`. No checkout, no\n worktree: the files are already in front of you. This is the mode that runs\n after an authoring skill.\n4. **Empty, with a clean tree** means the current `HEAD` against `main`:\n `git diff --name-only --diff-filter=d origin/main...HEAD`.\n\nNarrow to `src/**/*.mdx` and `src/**/*.md`. If nothing changed, say so and stop.\nNever review anything under `build/`.\n\n**For modes 1 and 2, check out the target before inspecting anything.** Your\nworking tree is almost certainly on a different branch, and linting it silently\nreports on the wrong content.\n\nFor a PR, check the branch out in the main working tree so any edit that follows\nlands on the open branch:\n\n```bash\ngit stash list # confirm nothing is about to be lost\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse `git checkout `, not `git checkout -b` or a `--no-track` branch. A\nnew branch is only correct when the review is of `main`, or when the user asks\nfor a separate branch of their own edits. Confirm the checkout by grepping for a\nstring the diff added.\n\nFor a review with no edits to follow, a detached worktree is also fine:\n\n```bash\ngit worktree add --detach /review-wt origin/\n```\n\nDo all reading and linting inside it, and `git worktree remove --force` it when\nthe review is done.\n\nState the target, the resolved SHA or \"working tree\", and the file count before\ngoing further.\n\n## Step 2. Run Vale\n\nRun `make lint_prose FILES=\"\"`, in the main checkout or a worktree alike.\nThe target installs the Vale version pinned in `.mise.toml` into `.bin/vale` when\nit is missing, so a fresh worktree needs no setup beyond network access.\n\nVale is deterministic and CI blocks on it, so its output is not a judgment call.\nReport every violation with its file and line. If invoked with `--fix`, correct\nthem; otherwise list them.\n\nLint the merge-base version of each changed file as well, and report the\ndifference rather than the raw count:\n\n```bash\ngit show origin/main: > /base-\nmake lint_prose FILES=\"/base-\"\n```\n\nA file that already failed on `main` carries pre-existing debt the author did\nnot introduce. A file that was clean on `main` and fails now is this diff's CI\nblocker. Say which one it is, because attribution is the difference between a\nfinding the author has to fix and one they can reasonably decline.\n\nReading the diff text is not a substitute for either run. A patch shows added\nlines without their column offsets or their surrounding component, which is\nexactly what these rules turn on.\n\nVale covers terminology, contractions, first person, future tense, Oxford\ncommas, spaced em dashes, navigation-path arrows, and heading case. **Do not\nspend model judgment re-checking what Vale already checks**, with one exception:\nVale does not scan every part of an MDX file, so a clean run is not proof of\ncompliance. It misses content inside JSX components (``, ``, ``,\n``, ``) and inside table cells. A page can pass Vale with four\nspaced em dashes in it.\n\nGrep the mechanical rules yourself over any file whose diff touches those\nplaces:\n\n```bash\ngrep -nE ' — | – ' # spaced em dashes\ngrep -nEi \"\\b(don't|can't|won't|isn't|it's|you'll)\\b\" # contractions\ngrep -nE '\\b(we|our|us|I)\\b|\\bwill [a-z]+\\b' # first person, future tense\ngrep -n '→' # navigation arrows\n```\n\nReport a hit inside a component the same way you would report a Vale error: it\nwould be one if Vale could see it. A `—` used as an empty table-cell marker is\nfine and is not a finding.\n\n## Step 3. Check structure against the style guide\n\nRead the \"Structure conventions\" section of `AGENTS.md` in the repository root,\nthen check the changed hunks against it. For each finding, quote the rule you are\napplying.\n\nLook for these, and nothing else:\n\n- **A new section or page that does not open with a one-sentence definition** of\n what the thing is or does, followed by the benefit, then the task. Skip when\n the section continues directly from the one above it.\n- **Steps introduced without a colon lead-in**, or steps that are not imperative.\n Skip for a list that is not a procedure.\n- **Three or more options, parameters, or permissions written as prose** where\n `- **Term**: Explanation.` would carry them. Skip for fewer than three.\n- **A feature or class linked on repeat mentions**, or a first mention that is\n not linked. Skip when the repeat is far enough down the page to be a genuine\n re-entry.\n- **A permission, plan tier, or preview requirement stated after the steps it\n governs** rather than before them.\n- **A hard constraint hedged** (\"it is generally not possible to change this\")\n where the guide calls for a flat fact (\"Once set, it cannot be changed.\").\n\nPointer phrasing is deliberately absent from that list. Both the long form (\"For\nmore information, see [Page]\") and the short form (\"See [Page]\") are\nestablished. Do not convert between them in either direction.\n\n## Step 4. Check the style guide items Vale cannot see\n\nRead the \"Style guide\" section of `AGENTS.md`. Vale enforces the mechanical half.\nThese are the rules that need reading:\n\n- **Passive voice** where the actor is known. \"Feedback is treated as a signal\"\n hides who treats it. Skip when the actor is genuinely irrelevant or unknown.\n- **Filler and hedging**: \"Note that\", \"Specifically\", \"simply\", \"easily\",\n \"just\", \"very\", \"basically\", \"obviously\". Cut the word, keep the sentence.\n- **A pronoun, \"this\", or \"the above\" whose antecedent the diff removed.**\n Compression is the usual cause: the noun the sentence refers back to sat in a\n clause the edit cut. Name the thing again.\n- **A condition, default, or requirement the diff shortened away.** Compare the\n hunk against its base rather than reading the new text alone. A sentence that\n got shorter by dropping when the behavior applies, or what value it applies\n to, is a regression, and it lints clean. Quote \"Be concise: cut filler words\n and wordy phrases\" and name the fact the cut removed.\n- **Product versus common noun capitalization.** A capitalized feature name that\n appears nowhere else in the file, or that disagrees with the UI label used\n elsewhere on the same page, is the tell. Grep the file for the term's other\n casings before reporting.\n- **Bold in body text** beyond UI labels. Match what the rest of the page does\n rather than an abstract standard.\n- **Repetition inside the diff.** The same list of items enumerated twice in one\n short section, or a sentence restating the one above it.\n- **Link text** that does not describe its destination, and two different labels\n pointing at the same anchor.\n- **Version minimums written with `>=` in prose.** The convention is \"v0.153.4 or\n later\"; `>=` belongs only in package specifiers such as `langsmith>=0.3.13`.\n\nMeasure before reporting a convention violation. If you are about to say a\nheading form or phrasing is wrong, grep the repository for how often it already\nappears. A form used widely is established practice, not a defect, however much\nthe guide seems to prohibit it. Report the count either way.\n\nA diff can also **leave** a convention rather than break a new one. Lowercasing\nthe explanation in `- **Term**: Explanation.`, dropping a trailing period, or\nswapping a colon lead-in for a dash each reads as a harmless copy edit on its\nown. Compare the before and after of that exact form, then count both spellings\nacross `src/`. When the base was following the majority, the change is the\nfinding.\n\nMeasure the same way when the diff **adopts** a convention rather than breaks\none, because a repeated block has three parts and matching two of them still\nlands wrong:\n\n- **Component.** `` or `` or plain prose.\n- **Wording.** Byte-identical to the siblings, or subtly reworded.\n- **Placement.** Before or after the intro paragraph, relative to imports and\n the first heading.\n\nA status callout copied word for word from the one page in thirteen that puts it\nbelow the intro is a finding, and only a placement count surfaces it. Report the\ncount for each of the three.\n\nWhen the same block appears on three or more pages, say so: it belongs in\n`src/snippets/` rather than duplicated. See `add-docs-page`.\n\n## Step 5. Check the mechanics the diff implies\n\nOnly when the diff triggers them:\n\n- A new page: is it in `src/docs.json`, in the right product, tab, and group?\n- A renamed or deleted page: are inbound links and the `docs.json` entry both\n updated?\n- New internal links: root-relative, and free of `/python/` or `/javascript/`?\n- A new code block: does it carry a real language tag, and are imports sorted?\n- A page or heading that changed URL: is there a redirect?\n\nThe `add-docs-page` skill covers all five in detail. Point at it rather than\nrestating the procedure in a finding.\n\n## Step 6. Report\n\nGroup by file. For each finding:\n\n```txt\nsrc/langsmith/example.mdx:42\nRule: \"State requirements and constraints up front\"\nThe admin permission requirement appears after step 3, but governs all of them.\nSuggested: move it above the numbered list.\n```\n\nEnd with a one-line verdict: what blocks merge (Vale violations, missing nav\nentry, broken link) versus what is a suggestion.\n\nIf nothing turns up, say that plainly. \"No findings\" is a valid and useful\nresult, and is more useful than a manufactured one.\n\n## Running after an authoring skill\n\n`add-docs-page` invokes this skill at its verification step, in working-tree\nmode, on the files it just changed. Two constraints keep that useful:\n\n- **Review finished edits, not drafts.** Findings on a half-written section go\n stale as soon as writing resumes, and reporting them trains the reader to\n ignore the report. Run after the edit is complete and before the commit.\n- **Scope to the files the authoring pass touched.** Do not widen to the rest of\n the branch. If other files changed earlier and also want review, say so and\n let the user ask.\n",".agents/skills/docs-tooling-notion/SKILL.md":"---\nname: docs-tooling-notion\ndescription: Document new or changed docs-team tooling on the Notion tooling pages.

This skill routes a change to the one page that owns it, then edits that\npage without tripping the known Notion failure modes.\n\nRequires the Notion MCP server (`notion-fetch`, `notion-update-page`).\n\n## Rule one: one home per topic\n\nEvery topic lives on exactly one page. Duplicates drift, and drift is worse than\na long page. Before writing anything, search the other four pages for the topic.\nIf it already appears somewhere, update it there instead of adding a second\ncopy.\n\n## Step 1. Route the topic\n\n| Page | ID | Owns |\n|------|----|------|\n| [Docs tooling and agents](https://app.notion.com/p/3ca808527b178153839bff0f2831914c) | `3ca808527b178153839bff0f2831914c` | Parent directory. Page table, \"Owned elsewhere\" list, quick-answers FAQ. |\n| [Docs tech stack](https://app.notion.com/p/30c808527b178073876af57f7d87d8ca) | `30c808527b178073876af57f7d87d8ca` | The production site only: fencing, `src` versus `build`, build pipeline, navigation, integration docs. |\n| [Local setup and quality gates](https://app.notion.com/p/3c8808527b1781dcbaf5d04834a843bf) | `3c8808527b1781dcbaf5d04834a843bf` | mise and prek setup, the `docs` and `mint` CLIs, Vale, git hooks, broken-link triage, the CI matrix, preview deployments, publishing. |\n| [Docs automation and agents](https://app.notion.com/p/3c8808527b17815b81cbf92896b5c3ee) | `3c8808527b17815b81cbf92896b5c3ee` | Scheduled workflows and their cron times, the changelog agents, the #ask-docs intake agent, tracked skills, agent-instruction files, MCP servers. |\n| [Reference docs](https://app.notion.com/p/3c9808527b1781858ebbe92914b02970) | `3c9808527b1781858ebbe92914b02970` | The three LangSmith OpenAPI sources, reference.langchain.com, the `@[ClassName]` link map. |\n\nMost new tooling lands on **Docs automation and agents** (a workflow, script,\nagent, skill, or MCP server) or **Local setup and quality gates** (anything a\ncontributor runs on their own machine or that gates a PR).\n\nThe changelog **system** is not owned by these pages. [LangSmith release\nnotes](https://app.notion.com/p/31b808527b178026943ac2b1ae244021) owns fragments,\nthe fragment schema, and both pipelines. Link to it; do not re-explain it. These\npages keep only the runbook: deployment IDs, HTTP routes, required environment\nvariables, and recovery paths.\n\n## Step 2. Check whether it belongs in Notion at all\n\nDo not write a Notion page for something the repo already documents where people\nfind it. Deliberately excluded: `IDE_SETUP.md`, `.github/brand-guidelines.md`,\n`.github/pull_request_template.md`, `.github/CONTRIBUTING.md`, the issue\ntemplates, and the navigation map, which lives only in `AGENTS.md` because the Notion copy went stale once already.\n\nSkills are the same: a skill is its own authoritative reference. Name it on the\nNotion page, say what it covers and the one or two facts a reader needs in order\nto decide whether to open it, and stop there.\n\nUntracked tooling is not team infrastructure. Anything under a gitignored path\nis personal tooling and does not go on these pages.\n\n## Step 3. Write it\n\nFollow the `docs-team-voice` skill. Do not restate its rules here. The three that\nget missed most often on Notion pages: no first person, no spaced em dashes, and\ndefinition lists written as `- **Term**: Explanation.` with the colon outside the\nbold and a period at the end.\n\nOpen a section with a one-sentence statement of what the thing is, then what it\nenables, then the procedure. Close a substantial page with `## See also`.\n\n## Step 4. Edit safely\n\nFetch the page with `notion-fetch` before every edit. Then use\n`notion-update-page` with `command: \"update_content\"` and narrow\n`content_updates` pairs rather than rewriting the page.\n\nFive failure modes, each of which has already cost a debugging cycle:\n\n- **`old_str` must match the stored indentation exactly.** Tables are stored\n with no leading tabs; callouts do use tabs. A mismatch fails with an\n indentation hint.\n- **Never use `replace_content` on a page holding an uploaded image.** The\n fetched image URL is a short-lived signed S3 link, and rewriting the page body\n can break the image.\n- **A timed-out or async update may already have applied.** Updates default to\n `allow_async: true`. Fetch the page and verify before retrying anything that\n appeared to fail, otherwise the retry duplicates the block.\n- **Bold that contains inline code mid-sentence renders as stray asterisks.**\n Bold wrapping code entirely is fine. Reword so the two do not collide.\n- **In-page anchor links do not resolve.** Notion addresses blocks by ID, not by\n heading slug. Reference sections by name in prose.\n\n## Step 5. Add a row to the Detailed list\n\nThe parent page embeds a **Detailed list** database\n(`collection://3ce80852-7b17-8004-8735-000bc758a8cd`) holding one row per piece\nof tooling. Prose on a page is where someone reads about a thing; this database\nis where they find that it exists at all. It is easy to miss, because the parent\npage renders it as a single inline block.\n\nEvery new workflow, script, skill, agent, MCP server, or git hook gets a row.\nThe schema is Title, Description, Docs page (the URL of the page that explains\nit), Source (the repo paths it lives at), and Type, a select over `GH Actions\n(scheduled)`, `GH Actions (PR/CI)`, `Fleet agent`, `Deep agent`, `External bot`,\n`Skill`, `MCP server`, `Manual script`, and `Git hook`.\n\nQuery it with `notion-query-data-sources` before adding, so a rename becomes an\nupdate rather than a duplicate row. Renaming or moving a file means updating\n`Source` here too, not only in the prose: four rows still pointed at a skills\ndirectory that had been renamed months earlier, and every one of them read as\nplausible.\n\n## Step 6. Close the loop\n\nUpdate the parent page's page table when a page's scope changes, and repoint any\n`## See also` entry that is now wrong. Report which page was edited and what was\ndeliberately left out, so the routing decision is reviewable.\n",".agents/skills/open-docs-pr/SKILL.md":"---\nname: open-docs-pr\ndescription: Open a pull request for finished docs changes. Covers cutting the branch from the latest origin/main, the lint and link gates, the commit, writing the PR description in the repo's short format with the AI disclosure line, pushing safely, and watching the PR checks until they pass. Use when asked to open, create, put up, or submit a docs PR, or after add-docs-page or docs-edit finishes an edit that has no PR yet.\n---\n\n# Open a docs pull request\n\nThis skill starts when the edit is finished and ends when the PR is open and\nits checks are green. Editing a PR that already exists is `docs-edit`, not this\nskill: pushing a second PR against a teammate's work is the failure that skill\nprevents.\n\nThe rules every task follows live in `AGENTS.md`. This skill is the order to\napply them in.\n\n## Step 1. Branch from the latest main\n\nNever commit to `main`. Cut a new branch from a freshly fetched `origin/main`,\nnot from a local `main` that may be days old:\n\n```bash\ngit fetch origin main\ngit switch -c / --no-track origin/main\n```\n\n`--no-track` stops the branch from tracking `origin/main`, so a bare push\ncannot land on `main`.\n\nThe main checkout may be shared with other agent sessions that switch branches\nunder you. Prefer a worktree inside the checkout:\n\n```bash\ngit worktree add -b / --no-track .claude/worktrees/ origin/main\n```\n\nA new worktree's `.mise.toml` is untrusted, so the first commit fails at the\nVale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix. Run `make skills` in the worktree too if you use Claude Code.\n\n## Step 2. Run the gates\n\nRun each gate that applies to the change before committing. CI runs the same\nones, so a skipped gate becomes a red check later.\n\n- **Prose review**: Run the `docs-review` skill on the changed pages. It covers\n the style-guide rules Vale cannot see. Skip it for a change with no prose.\n- **Vale**: `make lint_prose FILES=\"\"`. Fix every error.\n- **Links**: `make broken-links-with-anchors` when links, page names, anchors,\n or `src/docs.json` changed. Read only the indented `⎿` lines.\n- **Code samples**: `make test-code-samples FILES=\"\"` when a\n file under `src/code-samples/` changed.\n- **Pipeline**: `make test` and `make lint` when `pipeline/`, `scripts/`, or\n `tests/` changed.\n\nNote which gates you ran. The PR checklist asks for them.\n\n## Step 3. Commit\n\nStage only the files the change touched, then check that nothing secret is\nstaged:\n\n```bash\ngit diff --cached --name-only\n```\n\nWrite the subject line in the form recent merged PRs use: `docs: ...` for\ncontent, `docs(): ...` when one product is involved, and `chore: ...`\nfor tooling. The body explains why, not what.\n\nDo not add a `Co-Authored-By` trailer for an AI agent. A ruleset on `main`\nrejects the Claude trailer at merge time, and squash merges carry branch commit\ntrailers into `main`.\n\n## Step 4. Write the PR description\n\nUse the sections in `.github/pull_request_template.md`: **Why**, **Changes**,\n**Review notes**, **Related**, and the checklist. Fill each one in, and delete\nany section that would be empty rather than leaving placeholder comments.\n\n- **Why**: The problem the change solves, in two or three sentences.\n- **Changes**: One bullet per meaningful change, naming the file or page.\n- **Review notes**: Where to look hardest, decisions the reviewer may disagree\n with, and every claim you could not verify against source. A preview link\n goes here once the preview deploys.\n- **Related**: Issues, PRs, Linear tickets, and Slack threads. Write\n `Closes [DOC-N]()` to let `sync-linear-issue-from-pr.yml` move\n the Linear issue with the PR.\n- **Checklist**: Tick only what you actually did in Step 2. Leave the rest\n unticked rather than claiming it.\n\nEnd with one plain sentence that discloses AI involvement, for example\n`Prepared with Claude Code.` Do not add the `🤖 Generated with [Claude Code](...)`\nbadge or any similar badge. The `check-pr-ai-attribution` check fails a PR\nwhose description carries one, because the squash merge would copy it into the\ncommit on `main`.\n\nWrite the description to a file and pass it with `--body-file`. A shell\nheredoc inside `--body \"$(...)\"` breaks on apostrophes in some shells.\n\n## Step 5. Push and open the PR\n\nConfirm the remote is a `langchain-ai` repository, then push with an explicit\nremote and branch. Never run a bare `git push`.\n\n```bash\ngit remote get-url origin # must be github.com/langchain-ai/docs\ngit push -u origin \ngh pr create --base main --head --title \"\" --body-file \n```\n\nOpen it as a draft (`--draft`) if it is not ready for review.\n`pr-welcome-comment.yml` requests reviewers from `.github/OWNERS` when the PR\nleaves draft, so do not request reviewers by hand unless asked.\n\nIf you later push more commits, first check that the PR has not merged. A push\nto a merged PR's branch lands nowhere:\n\n```bash\ngh pr view --json state,mergedAt\n```\n\n## Step 6. Watch the checks\n\n```bash\ngh pr checks --watch\n```\n\nFor a failure, read the log with `gh run view --log-failed`, fix the\ncause on the same branch, and push again. Editing the PR description reruns the\ndescription checks without a new commit.\n\nFor same-repo PRs, `create-preview-branch.yml` comments a preview URL. Forks do\nnot get one.\n\n## Step 7. Record tooling changes\n\nWhen the PR adds or changes a script, workflow, Makefile target, check,\nscheduled job, or skill, invoke `docs-tooling-notion` before handing off.\n\n## Report\n\nGive the PR URL, the branch, the gates you ran and their results, the state of\nthe checks, and anything you could not verify.\n","docs-release-watch/skills/deepagents-code/SKILL.md":"---\nname: deepagents-code\ndescription: Analyze Deep Agents Code releases against LangChain Deep Agents Code docs and prepare one-feature documentation updates.\n---\n\n# Deep Agents Code docs release skill\n\nUse this skill when the product is Deep Agents Code (Products and setup → Deep Agents Code).

Also the source of the Agent Server OpenAPI spec PRs |\n| Helm charts | [langchain-ai/helm](https://github.com/langchain-ai/helm) | `charts/langsmith/values.yaml` for defaults, `templates/_helpers.tpl` for the value-to-environment-variable mapping |\n| OpenEvals | [langchain-ai/openevals](https://github.com/langchain-ai/openevals) | Prebuilt evaluators |\n\nTwo traps worth naming:\n\n- **A private repo is still readable through `gh`.** `gh api` works on\n langchainplus and langgraph-api with the usual credentials. GitHub code search\n is unreliable on the larger ones, so fall back to the git trees API and fetch\n a path directly.\n- **langchain-ai/deployments is archived.** Its GitOps content moved into\n langchainplus. A skill, script, or note that still points at it is stale.\n\nA self-hosted LangSmith claim usually spans two repositories: the chart sets a\nvalue, and the backend decides what to do with it. Check both before describing\nprecedence, because the chart alone does not tell you which setting wins.\n\n## Step 3. Verify the claim, not the sentence\n\nRead the code path that produces the behavior, rather than a name that sounds\nlike it. Three failures that recur:\n\n- **A resolution order inferred from a settings table.** Find the query or the\n conditional that picks a value. An `ORDER BY`, a `COALESCE`, or an `or`\n expression is the precedence; a list of configurable fields is not.\n- **A defensive pattern copied from another sample.** Check whether the guarded\n case can occur. If the constructor only builds an object when a field is\n present, a `.get` with a default is documenting a state that never exists.\n- **A version or model identifier from memory.** Fetch it. The repository's own\n internal consensus is evidence about the repository, not about the provider.\n For model IDs specifically, see the Model references section of `AGENTS.md`.\n\n## Step 4. Record what you checked, and what you could not\n\nName the file and symbol in the pull request body, not just the conclusion. A\nreviewer can then disagree with the evidence rather than with an assertion.\n\nState the gaps in the same place. Common ones that no amount of source reading\ncloses:\n\n- **A UI string.** Source gives you a field and a component; only the running\n product gives you the rendered label. Describe the behavior rather than\n quoting a label you have not seen.\n- **The model-dependent half of a sample.** Say that CI has yet to run it.\n- **A beta surface.** `langchain.mcp` and similar namespaces can move under a\n page that was accurate when written.\n\nWriting \"not verified: the visible label of this control\" is a better outcome\nthan a confident sentence a reader discovers is wrong.\n\n## Related\n\n`AGENTS.md` holds the rules that apply to every edit, including never\nfabricating an example and testing code before publishing it. Use\n`docs-code-samples` when the claim belongs in a runnable sample rather than in\nprose, and `docs-review` for the style pass once the facts are settled.\n",".agents/skills/update-integrations-prs/SKILL.md":"---\nname: update-integrations-prs\ndescription: >-\n Process open LangChain docs integration PRs against the hosted-guide featuring\n policy (50K monthly downloads or maintainer feature override).

Inspect the current branch\n\n```bash\ngit branch --show-current\ngh pr view --json number,title,url,author,maintainerCanModify,files,body\ngit diff --stat upstream/main...HEAD\n```\n\nFind the LangChain-related package name(s) from `packages.yml`, MDX install snippets, or registry metadata. Ignore unrelated packages with similar names.\n\n### 2. Measure downloads\n\n**PyPI** (last ~30 days, no mirrors):\n\n```bash\ncurl -s \"https://pypistats.org/api/packages//overall?mirrors=false\" \\\n | python3 -c \"import sys,json; d=json.load(sys.stdin); data=d.get('data',[]); last30=data[-30:] if len(data)>=30 else data; print(sum(x.get('downloads',0) for x in last30))\"\ncurl -s \"https://pypistats.org/api/packages//recent\"\n```\n\n**npm** (last month):\n\n```bash\ncurl -s \"https://api.npmjs.org/downloads/point/last-month/\"\n```\n\nReport the number to the user before converting when they asked for downloads only.\n\n### 3. Rebase\n\n```bash\ngit fetch upstream main\ngit rebase upstream/main\n```\n\n- Keep contributor commits; put the conversion in a **new** commit after rebase.\n- On heavy merge history, cherry-pick content commits onto `upstream/main`, then convert.\n- Drop obsolete Card grids that main replaced with `IntegrationDownloads`.\n- Drop redirects for pages that were never on `main`.\n- Drop unrelated `packages.yml` download-count churn from bot commits.\n\n### 4a. External conversion (under 50K)\n\n1. **Delete** hosted MDX (component page and provider page if present).\n2. **Add YAML** under the correct language + component in `scripts/data/integration_external_docs.yaml`:\n\n ```yaml\n - name: ClassOrDisplayName\n pypi: langchain-example # or npm: \"@org/pkg\" under javascript:\n docs_url: https://partner.example/docs\n ```\n\n Prefer partner docs, then public GitHub/GitLab README, then PyPI/npm.\n3. **Downloads snippet** (sort by `data-sort-value`): add a row to the matching `src/snippets/oss/*-*-downloads.mdx` (for example `python-sandboxes-downloads.mdx`). Match existing badge markup.\n4. **`all_providers`**: card with external `href` (alphabetical). Use `icon=\"link\"` or an existing provider icon. Card body max **160 characters**. If a draft description is longer, shorten it to one factual sentence ≤160 characters; do not invent claims. Limit: `PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`.\n5. **`packages.yml`**: append only for a public LangChain-related package. Ensure a trailing newline before appending. Omit `path: .`. Skip if the source repo is private or not a normal public VCS listing.\n6. **Nav / redirects**: remove `docs.json` entries and redirects for deleted never-on-main pages. Do not add redirects for pages that never shipped.\n7. **Deep Agents / indexes**: if the PR added provider cards that main no longer uses, prefer downloads tables and index grids; keep brief mentions only when main already lists providers that way.\n\nAlign listings with **partner docs**, not stale PR page counts.\n\n### 4b. Hosted / featured path (≥50K or override)\n\n1. Keep (or fix) hosted MDX; test code examples when touching them.\n2. Frontmatter: follow templates under `src/oss/*/integrations/**/TEMPLATE.mdx`. Do not set `featured: true` unless a maintainer asked.\n3. Prefer `langchain` imports over `langchain_core` when editing kept pages.\n4. For featuring: set `highlight: true` in `packages.yml` only when asked; regenerate overview with the partner package table tool, do not hand-edit `overview.mdx`.\n5. Update `src/docs.json` if adding a page that should stay.\n\n### 5. Commit and handoff\n\n- Conversion commit message focuses on why (threshold / external listing / feature).\n- Show `git diff --stat upstream/main...HEAD` and downloads in the summary.\n- Note `maintainerCanModify` for push later.\n- **Do not push** unless the user asks. Use force-with-lease after rebase when pushing to the PR head.\n- If `maintainerCanModify: false`, say so and ask whether to open a replacement PR.\n\n## Hard rules\n\n- Ask for clarification rather than assuming package identity or feature overrides.\n- Never fabricate download counts, docs URLs, or package names.\n- Never edit `build/`.\n- Never hand-edit generated overview tables.\n- When appending to `packages.yml`, ensure a trailing newline first.\n- Run `make lint_prose FILES=\"...\"` on changed MDX before handoff when prose changed.\n- Follow repo git safety: no bare `git push`; no force to main; no commit unless asked (except when the user said \"go\" / \"next branch\" for this workflow, commit the conversion).\n\n## Common pitfalls\n\n| Pitfall | Fix |\n|---------|-----|\n| Wrong package (similar name on PyPI) | Confirm against install snippets and partner repo |\n| Re-adding Card grids removed on main | Use `IntegrationDownloads` / YAML only |\n| Redirects for never-shipped pages | Delete them |\n| Duplicate table rows | Remove YAML if keeping hosted page |\n| Private source repo | Skip incomplete `packages.yml` entry |\n| JS + Python packages | Add both YAML sections / download rows when both exist |\n\n## Reference\n\n- Eligibility docs: `/oss/contributing/publish-langchain#eligibility-for-hosted-guides`\n- YAML data:

add-docs-page\ndescription: Add, move, rename, or delete a page on the LangChain docs site. Covers choosing the source directory, writing frontmatter, placing the entry in src/docs.json navigation, adding redirects, and verifying with the lint and broken-link gates. Use when asked to add a new doc or page, move or rename a page, put something in the nav, or add a redirect.\nlicense: MIT\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# Add or move a docs page\n\nA page is not finished when the MDX file exists. It also needs a navigation\nentry, and a move or deletion needs a redirect. CI enforces both.\n\nRead `AGENTS.md` for the navigation map, the style guide, and the frontmatter\nrules. This skill covers the procedure around them and does not repeat them.\n\n## Step 1. Choose the source directory\n\nUse the \"Source directory summary\" table in `AGENTS.md` to go from subject to\ndirectory. Two traps:\n\n- Directory names do not match navigation names. `src/langsmith/fleet/` appears\n as \"No-code agents\"; `src/langsmith/managed-deep-agents*.mdx` appears under\n Build, not under a LangSmith menu.\n- Lifecycle menus mix products. Build draws from both `src/oss/` and\n `src/langsmith/`; Test, Deploy, and Monitor all draw from `src/langsmith/`.\n\nNever write to `build/`. It is Mintlify output, regenerated by `make build`.\n\n## Step 2. Write the page\n\nRequired frontmatter:\n\n```yaml\n---\ntitle: Clear, concise page title\ndescription: SEO summary with no markdown, no links, and no backticks\n---\n```\n\nFor OSS pages that differ by language, use `:::python` and `:::js` fences in one\nfile rather than writing two files. The build pipeline emits both versions.\n\nTake every fact on the page from the product source, not from memory, a sibling\ndocs page, or the request that asked for the page. This covers behavior,\ndefaults, field names, version minimums, and examples. Use the\n`verify-against-source` skill to find the repository that owns each claim. Never\nfabricate a value to fill a gap. Leave the claim out, and list what you could\nnot confirm in the pull request body and in your reply to the requester.\n\n## Step 3. Add the navigation entry\n\nNavigation lives in `src/docs.json` under `navigation.products`. There are two\nproducts: `products[0]` is AGENT DEVELOPMENT LIFECYCLE (Home, Build, Test,\nDeploy, Monitor) and `products[1]` is PRODUCTS AND SETUP (LangSmith setup, LLM\nGateway, No-code agents, Engine, Deep Agents Code).\n\nEach menu item is addressed by its `item` key, then nests one of two ways:\n\n- `menu[].tabs[].pages[]` for most menu items.\n- `menu[].dropdowns[].tabs[].pages[]` for Build, which has Python and\n TypeScript dropdowns.\n\nA `pages` array holds page-path strings and `{\"group\": ..., \"pages\": [...]}`\nobjects, nested to any depth.\n\nThree rules:\n\n1. **A language-versioned OSS page needs two entries.** Build page paths carry\n the language segment (`oss/python/deepagents/overview` and\n `oss/javascript/deepagents/overview`), so one new page means one entry in the\n Python dropdown and one in the TypeScript dropdown. Omitting the TypeScript\n entry is the most common miss.\n2. **Page paths omit the `src/` prefix and the file extension.**\n `src/langsmith/sandboxes.mdx` is `\"langsmith/sandboxes\"`.\n3. **A new group leads with an index page:**\n `\"pages\": [\"group/index\", \"group/page\"]`.\n\nIntegration pages are the exception. Add them to the component's `index.mdx`\ninstead, and touch `docs.json` only when creating a brand-new component group.\n\n## Step 4. Add redirects for a move, rename, or deletion\n\nFor a move or rename of a file that was already on `main`, run the repo's mover first. It rewrites cross-references\nacross the corpus, which hand-editing misses: every link to the page in every\nform (`/oss/langchain/x`, `/oss/python/langchain/x`, `href=\"...\"`), plus the\n`src/docs.json` nav entries and redirect destinations that name it:\n\n```bash\nuv run docs mv src/langsmith/old-name.mdx src/langsmith/new-name.mdx --dry-run\n```\n\nRead any `Left ... links unchanged` warning in the output. It marks links the\nmover could not rewrite safely, such as an unversioned `/oss/integrations/...`\nlink that also reaches the other language's page. Fix those by hand.\n\nDrop `--dry-run` once the preview looks right. The mover does not add a\nredirect, so add one to the `redirects` array in `src/docs.json`:\n\n```json\n{ \"source\": \"/langsmith/old-name\", \"destination\": \"/langsmith/new-name\" }\n```\n\nRedirect paths are site paths and start with `/`. A language-versioned page\nneeds a redirect per language, plus one for the unversioned path if the old URL\nhad one.\n\n`scripts/check_removed_pages_redirects.py` runs in CI and fails the PR when a\npage leaves the navigation and its source file is gone with no redirect. The\nsame script fails when `docs.json` names a page whose file does not exist, so a\ntypo in a page path is caught there rather than at build time.\n\n## Step 4b. Two traps that fail silently\n\n### Extract a snippet once a block appears on three pages\n\n`AGENTS.md` covers how to add a snippet. The rule for **when**: the same block\nrepeated on three or more pages becomes one file under `src/snippets/`. A status\ncallout duplicated across a page family means the wording change that retires it\nis an edit to every page in the family, and one will be missed.\n\nVerify a new snippet reaches the build. The pipeline rewrites snippet imports to\nlanguage-specific paths, so `/snippets/langsmith/x.mdx` becomes\n`/snippets/python/langsmith/x.mdx` in the output, and a missing target renders as\nnothing at all rather than as an error:\n\n```bash\nls build/snippets/python/langsmith/.mdx build/snippets/javascript/langsmith/.mdx\n```\n\n### Editing a heading moves its anchor\n\nA heading's slug is derived from its text, so rewording one silently breaks every\n`#anchor` link pointing at it, including links from other pages and entries in\n`src/docs.json`. Grep before editing:\n\n```bash\ngrep -rn 'use-with-the-langsmith-gateway' src/ --include=*.mdx --include=*.json\n```\n\nChanging only capitalization is safe, because slugs are lowercased. Changing a\nword is not, and needs either a reworded inbound link or a redirect.\n`` and `` accept an explicit `id`, which is how to keep a\nlanding spot that is no longer a heading.\n\n## Step 5. Verify\n\nRun all three, in this order:\n\n```bash\nmake lint_prose FILES=\"src/path/to/page.mdx\"\nmake build\nmake broken-links-with-anchors\n```\n\nWhen `make build` fails with `Required uv version >=0.9.26 does not match the\nrunning version`, the local `uv` has drifted from the one `pyproject.toml`\nexpects. Run the pipeline directly rather than working around the build:\n\n```bash\nPYTHONPATH=\"$(pwd)\" .venv/bin/python -m pipeline build\n```\n\nA fresh git worktree has no `.venv`, and the same version check blocks\n`uv sync` from creating one. Point at the main checkout's interpreter instead;\n`PYTHONPATH` still loads the pipeline code from the worktree:\n\n```bash\nPYTHONPATH=\"$(pwd)\" /.venv/bin/python -m pipeline build\n```\n\nA fresh worktree's `.mise.toml` is also untrusted, so the first commit fails\nat the Vale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix.\n\n`make broken-links-with-anchors` depends on `build`, so it fails the same way.\nIts link-check half runs on its own once the build output exists:\n\n```bash\ncd build && mint broken-links --check-anchors | tee /tmp/bl.txt\ncd .. && python3 scripts/filter_mint_broken_links.py --check-anchors --input /tmp/bl.txt\n```\n\nRead `make broken-links-with-anchors` output by skipping to the `⎿` lines. Those are the only\nreal failures. A bare filename with no indented lines beneath it is an\nOpenAPI-generated page that exists at deploy time but not locally.\n\nFix every Vale finding. CI blocks on `lint_prose`, and its most common failure is\na spaced em dash (`word — word` must be `word—word`).\n\n## Step 6. Review the prose\n\nOnce the edit is complete and before committing, invoke the `docs-review` skill\non the files this pass changed. It runs in working-tree mode, so it needs no\ncheckout, and it covers the style-guide rules Vale cannot see: passive voice,\nfiller, product versus common noun capitalization, structure conventions, and\nlink text.\n\nRun it on finished edits only.

Use multiple `:snippet-start:` / `:snippet-end:` pairs in that file rather than splitting into several `.py` or `.ts` files. Reserve separate files for unrelated samples or when a page genuinely needs independent test entry points.\n\n**More than one snippet in one file**: A single code sample file can contain more than one named snippet using different `:snippet-start: snippet-name` and `:snippet-end:` pairs. Each snippet must have a unique name. Shared imports, helpers, and `:remove-start:` test harness code live once in the file; only the fenced regions between snippet tags appear in the generated MDX snippets.\n\n**When to split TypeScript samples into separate files**: Python samples can usually keep multiple snippets in one file because later definitions overwrite earlier ones at module scope. TypeScript and JavaScript cannot: `make test-code-samples` runs the entire `.ts` file, and every snippet's code executes in the same module scope. Split into separate `.ts` files when snippets would collide, for example:\n\n- Duplicate `import` bindings (for example two snippets both `import { interrupt } from \"@langchain/langgraph\"`)\n- Duplicate `const` / `let` / `class` / `function` declarations with the same name (for example two snippets both declare `const State = ...`)\n- Two self-contained snippets that each need their own imports and top-level setup\n\nKeep related snippets in one Python file when possible. For TypeScript, use one file per independently runnable snippet when imports or top-level bindings would conflict. Name sibling files clearly, for example `langgraph-interrupts-validate-conditional-edge-pattern.ts` and `langgraph-interrupts-validate-conditional-edge.ts`. Put shared test-only setup in `:remove-start:` blocks inside each file rather than importing between sample files.\n\nWithin a single TypeScript file, `:remove-start:` blocks and snippet regions share the same module scope when `make test-code-samples` runs the file. Do not import the same binding in both places. Keep imports that appear in the docs snippet inside the snippet; limit `:remove-start:` imports to symbols used only by the test harness (for example `Command`, `MemorySaver`) that the snippet does not import.\n\n## Step-by-step instructions\n\n### 1. Create the code sample file\n\nPlace the file under `src/code-samples/` in the folder for the product: `langchain/`, `langgraph/`, `deepagents/`, or `langsmith/` (for example, `src/code-samples/langgraph/langgraph-sql-agent.py` for LangGraph docs).\n\nUse a descriptive filename, for example, `return-a-string.py`, `return-a-string.ts`, or `traceable-pipeline.java`. When a doc page needs several code blocks for the same feature, add them as multiple snippets in one Python file (for example, `rubric-configure.py` with `rubric-configure-py` and `rubric-invoke-py`) instead of creating `rubric-configure.py` and `rubric-invoke.py`. For TypeScript, use one file per snippet when module-scope imports or bindings would conflict (see **When to split TypeScript samples into separate files** above).\n\n### 2. Add snippet delineators\n\nWrap the code that should appear in the docs with snippet tags:\n\n**Python:**\n```python\n# :snippet-start: snippet-name-py\nfrom langchain.tools import tool\n\n@tool\ndef get_weather(city: str) -> str:\n \"\"\"Get weather for a city.\"\"\"\n return f\"It is currently sunny in {city}.\"\n\n# :snippet-end:\n```\n\n**TypeScript/JavaScript:**\n```ts\n// :snippet-start: snippet-name-js\nimport { tool } from \"langchain\";\n// ... tool definition ...\n// :snippet-end:\n```\n\n**Java:**\n```java\n// :snippet-start: snippet-name-java\npublic class Example {\n public static void main(String[] args) {\n System.out.println(\"hello\");\n }\n}\n// :snippet-end:\n```\n\n**Go:**\n```go\n// :snippet-start: snippet-name-go\npackage main\n\nimport \"fmt\"\n\nfunc main() {\n\tfmt.Println(\"hello\")\n}\n// :snippet-end:\n```\n\n**Bash (cURL):**\n```bash\n# :snippet-start: snippet-name-sh\ncurl \"https://api.smith.langchain.com/api/v1/runs\" \\\n -H \"x-api-key: $LANGSMITH_API_KEY\"\n# :snippet-end:\n```\n\nChoose a unique `snippet-name` in kebab-case. All snippet names must include a language suffix: `-py` for Python files, `-js` for TypeScript/JavaScript files, `-java` for Java files, `-kt` for Kotlin files, `-go` for Go files, and `-sh` for bash/cURL files (for example, `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh`). This becomes the base of the output filename.\n\n### 3. Add runnable test code in remove blocks\n\nWrap any code that makes the sample executable but should not appear in docs.\n\n**Run snippet code before exiting.** `make test-code-samples` must execute the snippet body, not skip it. Do not put `raise SystemExit(0)`, `process.exit(0)`, or `exit 0` at the top of a file (or before `:snippet-start:`) so the test passes without running imports, constructors, or API calls. That only checks that the file parses; it does not validate function signatures, option shapes, or import paths.\n\nPlace `:remove-start:` blocks **after** the snippet when you can, so the harness runs assertions on values the snippet created:\n\n**Python (preferred):**\n```python\n# :snippet-start: example-py\nfrom deepagents import create_deep_agent\n\nagent = create_deep_agent(model=\"google_genai:gemini-3.6-flash\")\n# :snippet-end:\n\n# :remove-start:\nassert agent is not None\nprint(\"✓ example validated\")\n# :remove-end:\n```\n\n**TypeScript (preferred):**\n```ts\n// :snippet-start: example-js\nimport { DeepAgentsServer } from \"deepagents-acp\";\n\nconst server = new DeepAgentsServer({\n agents: { name: \"careful-agent\", interruptOn: { write_file: true } },\n});\n// :snippet-end:\n\n// :remove-start:\nif (!server) throw new Error(\"server not created\");\nconsole.log(\"✓ example validated\");\n// :remove-end:\n```\n\nFor samples whose docs show a blocking tail (for example `await server.start()`, `asyncio.run(main())`, or `agent.invoke()` with a live model), keep setup and construction in the snippet so types and signatures are checked, then move **only** the blocking call into a trailing `:remove-start:` block—or omit it when construction alone is enough:\n\n```python\n# :snippet-start: server-example-py\nserver = AgentServerACP(agent)\n# :snippet-end:\n\n# :remove-start:\n# Do not call await run_agent(server) here — it blocks on stdio.\nassert server is not None\nprint(\"✓ server-example validated\")\n# :remove-end:\n```\n\n**Do not** short-circuit before the snippet:\n\n```python\n# :remove-start:\nraise SystemExit(0) # BAD: snippet below never runs\n# :remove-end:\n\n# :snippet-start: example-py\n...\n```\n\nThe examples below show harness code that invokes behavior when the snippet defines callable helpers:\n\n**Python:**\n```python\n# :remove-start:\nif __name__ == \"__main__\":\n result = get_weather.invoke({\"city\": \"San Francisco\"})\n assert result == \"It is currently sunny in San Francisco.\"\n print(\"✓ Tool works as expected\")\n# :remove-end:\n```\n\n**TypeScript:**\n```ts\n// :remove-start:\nasync function main() {\n const result = await getWeather.invoke({ city: \"San Francisco\" });\n if (result !== \"It is currently sunny in San Francisco.\") {\n throw new Error(`Expected \"...\", got \"${result}\"`);\n }\n console.log(\"✓ Tool works as expected\");\n}\nmain();\n// :remove-end:\n```\n\nThe extraction script strips `:remove-start:` / `:remove-end:` content when extracting snippets.\n\n### 4. Test the code sample\n\nBefore extracting snippets, verify the code sample runs correctly:\n\n```bash\n# Test the file(s) you added (faster)\nmake test-code-samples FILES=\"src/code-samples/langchain/return-a-string.py\"\n\n# Or run all code samples\nmake test-code-samples\n```\n\nFor multiple files: `FILES=\"path1 path2\"`. Fix any failures before proceeding—do not extract snippets until the samples pass.\n\nTo run one product's samples, set `CODE_SAMPLE_PATHS` to space-separated directories under `src/code-samples/`, for example `CODE_SAMPLE_PATHS=\"src/code-samples/langsmith\" make test-code-samples`. It also narrows an explicit `FILES` list. CI runs one matrix leg per product this way (`oss` covers `langchain/`, `langgraph/`, and `deepagents/`; `langsmith` covers `langsmith/`), so a failure in one product never turns the other product's check red. A new top-level directory under `src/code-samples/` must be added to a leg in `.github/workflows/test-code-samples.yml`, or the workflow fails its coverage check.\n\nJava files (`.java`) under `src/code-samples/` are run using `jbang`. To keep CI green, Java samples must:\n\n- Print at least one line of output so it's obvious the sample ran\n- Exit successfully (code 0) when optional API keys are not set, for example:\n - `OPENAI_API_KEY` for LLM calls\n- Fail fast (non-zero exit) when a key is required for the sample to run, for example `manage-prompts-0-push.java` without `LANGSMITH_API_KEY`\n\n`make test-code-samples` runs every `.java` file under `src/code-samples/` in **lexical path order** (after all Python and TypeScript samples). That order is unrelated to section order in the docs. If one sample must run before another (for example creating a hub prompt before pulling it), name the source files so they sort correctly. For example, `manage-prompts-pull.java` runs before `manage-prompts-push.java` because `pull` sorts before `push`; use prefixes such as `manage-prompts-0-push.java` and `manage-prompts-1-pull.java` when you need push to run first.\n\nGo files (`.go`) under `src/code-samples/` are run with `go run` from `src/code-samples/`, which shares a single `go.mod`/`go.sum` at that directory (add new dependencies there with `go get`, then `go mod tidy`, similar to how `.ts` samples share `src/code-samples/package.json`). `go run .go` only compiles that one file, not its sibling files in the same directory, so — like Kotlin — put each snippet variant in its own file (`topic-before.go`, `topic-after.go`) rather than multiple snippets sharing one file: two files in the same package cannot both declare `func main()`. Go samples do not guard on missing keys — let the SDK call fail fast (matching Python's behavior) rather than skipping with a printed message. `make test-code-samples` runs `.go` files last, after Kotlin, in lexical path order.\n\nBash/cURL files (`.sh`) under `src/code-samples/` are run with `bash .sh` from `src/code-samples/`. Like Go, put each snippet variant in its own file (`topic-before.sh`, `topic-after.sh`) rather than sharing one file. Hide test-only setup (`#!/usr/bin/env bash`, `set -euo pipefail`, resolving a real ID/value for a `` shown in the docs) in `# :remove-start:`/`# :remove-end:` blocks so the visible snippet is exactly the illustrative curl command a reader would copy — including no shebang or `set -e` line. `curl` does not exit non-zero on an HTTP error status by itself, so when a script pipes a response into `jq` to extract a value used by a later request (for example resolving a project ID), add a hidden check that the resolved value is non-empty and not the literal string `null` before continuing, so a bad API response fails the test loudly instead of silently propagating into later requests. `make test-code-samples` runs `.sh` files last, after Go, in lexical path order.\n\nCheck formatting with:\n\n```bash\nmake lint\n```\n\nFix any ruff or mypy issues before proceeding. Run `make format` to auto-fix formatting.\n\n### 5. Run snippet extraction\n\nFrom the repo root:\n\n```bash\nmake code-snippets\n```\n\nTo limit extraction to specific samples (faster while iterating), set `CODE_SNIPPET_SOURCES` to space-separated repo-relative paths under `src/code-samples/`:\n\n```bash\nCODE_SNIPPET_SOURCES=\"src/code-samples/langsmith/trace.java\" make code-snippets\n```\n\nThis command:\n\n1. Runs `python scripts/extract_code_snippets.py` (line-based, Bluehawk-compatible; handles `/**` in TS strings). Optional env `CODE_SNIPPET_SOURCES` limits extraction to specific paths under `src/code-samples/`; other stems already in `src/code-samples-generated/` are left alone.\n2. Runs `scripts/generate_code_snippet_mdx.py` to produce MDX snippets in `src/snippets/code-samples/` (always regenerates MDX from everything under `src/code-samples-generated/`)\n\nOutput files:\n\n- `return-a-string.snippet.tool-return-values.py` → `tool-return-values-py.mdx`\n- `return-a-string.snippet.tool-return-values.ts` → `tool-return-values-js.mdx`\n\n### 6. Update the MDX file to use the snippet\n\nAdd an import at the top of the MDX file (after frontmatter):\n\n```mdx\nimport ToolReturnValuesPy from '/snippets/code-samples/tool-return-values-py.mdx';\nimport ToolReturnValuesJs from '/snippets/code-samples/tool-return-values-js.mdx';\n```\n\nReplace the inline code blocks with the snippet components:\n\n```mdx\n:::python\n\n\n\n:::\n\n:::js\n\n\n\n:::\n```\n\n## Naming conventions\n\n| Element | Convention | Example |\n|--------|-------------|---------|\n| Code file | Descriptive, kebab-case | `return-a-string.py`, `return-a-string.ts`, `traceable-pipeline.java`, `traceable-pipeline.kt`, `traceable-pipeline.go`, `traceable-pipeline.sh` |\n| Snippet name | Kebab-case with language suffix: `-py` for Python, `-js` for JS/TS, `-java` for Java, `-kt` for Kotlin, `-go` for Go, `-sh` for bash/cURL | `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh` |\n| MDX snippet (Python) | `{snippet-name}.mdx` (snippet name ends in `-py`) | `tool-return-values-py.mdx` |\n| MDX snippet (JS) | `{snippet-name}.mdx` (snippet name ends in `-js`) | `tool-return-values-js.mdx` |\n| Component name | PascalCase | `ToolReturnValuesPy`, `ToolReturnValuesJs` |\n\n## Script behavior\n\n`scripts/generate_code_snippet_mdx.py`:\n\n- Reads `*.snippet.*.py` and `*.snippet.*.ts` from `src/code-samples-generated/`\n- Wraps content in fenced code blocks (`` ```python `` or `` ```ts ``)\n- When a snippet contains a model string, expands it into a Mintlify `` with the seven quickstart provider tabs (Google, OpenAI, Anthropic, OpenRouter, Fireworks, Baseten, Ollama):\n - Python: `model=\"…\"` or `model = \"…\"`\n - TypeScript: `model: \"…\"` or `model = \"…\"` (including `let model = \"…\"`)\n - Only the quoted model ID is swapped per tab, so assignment vs property syntax is preserved\n - Put `# KEEP MODEL` / `// KEEP MODEL` on the line before a model string to leave that occurrence unchanged\n- Writes to `src/snippets/code-samples/{snippet-name}-py.mdx` or `-js.mdx`\n\nTo support additional languages, add config entries in that script.\n\n## Guidelines\n\n- **Prefer the plainest thing that runs.** Keep the snippet verbatim from the page, add hidden harness code only where CI differs from a reader's machine (a missing env var, a dataset name that must be cleared first), and do not add options, inputs, or indirection nobody asked for. The same applies to the runner and workflow around the samples: one job per product, re-run a job from the GitHub UI rather than adding an input for it, read what GitHub already knows (job names, conclusions) rather than passing artifacts around. If a change needs a diagram to explain, it is too much.\n- **Run snippet code in tests** — `:remove-start:` harnesses must not exit before the snippet runs. Let imports, constructors, and configuration execute so `make test-code-samples` catches wrong signatures, renamed options, and broken import paths. Put `SystemExit` / `process.exit` only after the snippet (or use them to skip a trailing blocking call such as `server.start()`, not the whole sample).\n- **Collocate related snippets** in one code sample file per doc page or feature when possible (Python and Java). Import each generated MDX snippet separately in the MDX file (for example, `` then `` from the same source file). For TypeScript, split into separate `.ts` files when snippets duplicate imports or top-level bindings; still import each generated MDX snippet in the MDX file the same way.\n- Do not mock LangChain internals (for example `unittest.mock.patch` on `init_chat_model` helpers) so that imports resolve real chat model instances. Do not use fake chat models in docs code samples (for example `GenericFakeChatModel`, `FakeListChatModel`, or other `langchain_core` testing fakes). Wire a real chat model (for example `ChatOpenAI`) so snippets match what readers run; `make test-code-samples` requires a valid API key when the sample calls the model.\n- Do not change `pyproject.toml` when making code sample changes.\n- Always run `make test-code-samples FILES=\"path/to/your/file.py\"` before `make code-snippets` to ensure new samples pass.\n- Run `make lint` once the code sample is written; fix any issues (or run `make format` to auto-fix).\n- Do not add code samples to linting ignore rules when making lint-related changes—fix the code instead.\n- `src/code-samples-generated/` is gitignored; regenerate with `make code-snippets`, narrowing to specific files with `CODE_SNIPPET_SOURCES` while iterating.\n- Reference `AGENTS.md` for docs style and rules.\n- Use `:::python` and `:::js` fences for language-specific content; the build produces separate Python and JavaScript doc versions.\n- For python tests, try to correct the type rather than adding `# type: ignore[arg-type]`\n","frontmatter":{"name":"docs-code-samples","description":"Use this skill when migrating inline code samples from LangChain docs (MDX files) into external, testable code files that are extracted by this repo’s snippet scripts and used as Mintlify snippets.

Covers checking out the PR's own branch instead of cutting a new one, forked cross-repository PRs, reading the real diff, checking the edit against related pages, and the verification to run before handing off. Use when asked to edit, revise, fix, or review changes on a named PR, branch, or existing page.\n---\n\n# Edit an existing docs page or PR\n\nThe failure this skill prevents: an agent asked to \"fix the wording on PR 1234\"\ncuts a fresh branch, commits there, and opens a second pull request against a\nteammate's work. Land edits on the branch that already exists.\n\n## Step 1. Check out the PR's own branch\n\nWhen the request names a PR, by number or URL, work on that PR's head branch.\n\n```bash\ngh pr view --json number,title,headRefName,baseRefName,author,isCrossRepository,files\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse plain `git checkout `. Do not use `git checkout -b` or `--no-track`:\neach produces a net-new branch, and committing there opens a second PR against\nsomeone else's work.\n\nA worktree on the PR's own branch is fine, and safer when other sessions share\nthe main checkout. Pass the existing branch name, never `-b`:\n\n```bash\ngit fetch origin \ngit worktree add # tracks origin/\n```\n\nThis fails if the branch is already checked out in another worktree. Use that\nworktree instead of forcing a second one.\n\nmise trusts config files by path, so each new worktree's `.mise.toml` starts\nout untrusted. The Vale pre-commit hook runs through `mise exec`, and the first\ncommit fails with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree, then commit again. To stop this\nfor good, add the main checkout to `trusted_config_paths` in\n`~/.config/mise/config.toml`. It trusts every worktree created inside the\ncheckout, such as `.claude/worktrees/*`, but not sibling directories.\n\nA local branch whose name merely mentions the PR is not the same branch. Confirm\nthat `git rev-parse HEAD` matches the `headRefOid` from `gh pr view` before\nediting, and that the branch has an upstream:\n\n```bash\ngit rev-parse --abbrev-ref @{upstream} # fails when the branch tracks nothing\n```\n\nCut a new branch only when the edits are your own and no open PR exists to land\nthem on, or when the user asks for one. Branch from the latest `origin/main`,\nnever from a stale local `main`.\n\n### Cross-repository PRs\n\nWhen `isCrossRepository` is `true`, the branch lives on a fork. Use `gh pr\ncheckout `, which configures the fork remote, and confirm push access before\ncommitting. Without it, the edits are stranded locally.\n\n## Step 2. Read the real diff\n\n```bash\ngh pr diff \n```\n\nPrefer this over `git diff main...HEAD`. A stale local `main` silently inflates\nthat diff with unrelated commits, and a branch that already merged `main` once\ninflates it further. To compare against the live base instead, fetch first and\nuse `git diff origin/main...HEAD`.\n\n## Step 3. Edit\n\n`AGENTS.md` holds the rules that apply to every edit: the style guide,\nfrontmatter, syntax, and the navigation map. Two that matter most here:\n\n- Match the conventions of the file you are editing. Do not restructure,\n combine, or split pages unless asked.\n- Never fabricate examples, field names, UI labels, or policy details. Verify\n each factual claim against the source it describes, and state plainly what you\n could not verify.\n\nFor voice and sentence rhythm while drafting, use the `docs-team-voice` skill. For\nadding, moving, renaming, or deleting a page, including navigation and\nredirects, use `add-docs-page`. When the edit is really a question of which page\nthe content belongs on, use `docs-restructure`.\n\n### Verify claims against source, not against other docs\n\nA sibling docs page is not a source. It is another claim, written by someone who\nmay have been guessing too, and two docs pages that agree can both be wrong.\nCheck the implementation:\n\n```bash\ngh api -X GET search/code -f q='LANGSMITH_GATEWAY repo:langchain-ai/langchain' \\\n --jq '.total_count, (.items[]?|.path)'\ngh api repos/langchain-ai/langchain/contents/ --jq .content | base64 -d\n```\n\nPython and TypeScript live in separate repositories and drift apart, so a table\nwith a Python column and a TypeScript column needs both checked:\n`langchain-ai/langchain`, `langchain-ai/langchainjs`, and for some providers a\ndedicated repository such as `langchain-ai/langchain-google`. A package's\n`CHANGELOG.md` gives the version a feature landed in, which is what a minimum\nversion column needs.\n\nState plainly what you could not verify. \"I could not confirm the Baseten row;\nno gateway references in either candidate repository\" is a useful review note.\nSilently keeping an unverified claim is not.\n\n### Read the pages around the one you are editing\n\nA page is one of several that cover the same feature. Others reach it from\nanother angle: a CLI reference, a permissions table, a list of Chat surfaces, a\nsetup guide, the pages that link to it. An edit made to one page in isolation\nleaves the set contradicting itself.\n\nBefore editing, find the related pages:\n\n```bash\ngrep -rliE \"|\" src --include='*.mdx'\ngrep -n \"\" src/docs.json\n```\n\nRead each one, then check for:\n\n- **Contradictions.** The edited page and a related one give different setup\n steps, defaults, or requirements. For example, a feature page that sets\n `LANGSMITH_API_KEY` while the CLI page recommends `langsmith auth login`.\n Settle it against source, then fix whichever page is wrong.\n- **Duplication.** A procedure the edited page restates from the page that owns\n it.

When two pages\ndisagree, the source decides, as described in the section above.\n\nKeep edits to related pages small: a cross-link, a corrected fact, or a short\nentry that points at the owner page.

Covers splitting a page that has grown too long, moving sections between pages, retiring a page, and fixing a topic documented in two places at once. Use when asked to streamline, simplify, consolidate, or reorganize docs, or when a page review keeps producing edits without the page getting shorter.\n---\n\n# Restructure docs across pages\n\nThe failure this skill prevents: an agent asked to \"streamline this page\" reorders\nits sections, collapses them into accordions, retitles them, and tabulates them,\nthirty times over, while the page gets longer. The page was never the problem.\nThree of its sections already existed on sibling pages.\n\nSingle-page skills cannot see that. `add-docs-page` owns one page's lifecycle and\n`docs-edit` owns one page's diff. This skill owns the question they cannot ask:\n**is this content on the right page at all?**\n\n`AGENTS.md` holds the navigation map, the style guide, and the frontmatter rules.\nThis skill covers the procedure around them and does not repeat them.\n\n## Step 1. Establish the page family\n\nA page almost never lives alone. Find its siblings before reading it closely:\n\n```bash\nls src/langsmith/llm-gateway*.mdx # a flat-file family\nls src/oss/deepagents/ # a directory family\ngrep -n '\"langsmith/llm-gateway' src/docs.json # what the nav groups together\n```\n\nThe nav grouping is the better signal when the two disagree: pages a reader\nmoves between are the pages whose content can be confused.\n\nThen list every heading in the family, so you are working from the whole shape\nrather than one file:\n\n```bash\ngrep -n '^## ' src/langsmith/llm-gateway*.mdx\n```\n\n## Step 2. Build a duplication map before writing anything\n\nThis is the step that does the work. For each H2 in the page you were asked to\nfix, search the rest of the family for the same content:\n\n```bash\ngrep -rn 'LANGSMITH_GATEWAY' src/langsmith/ --include=*.mdx\ngrep -rn 'Use a regional gateway' src/ --include=*.mdx\n```\n\nSearch for the distinctive noun, env var, or endpoint in the section, not for\nits heading. Duplicated content is usually retitled, which is why heading\nsearches miss it.\n\nRecord for each section: **does this topic already live somewhere else, and\nwhere?** Two copies that have drifted apart are the strongest finding available.\nIt means no page owns the topic, so both copies are edited independently and\nreaders get contradictions. In one real case the quickstart claimed TypeScript\nsupport for three providers while the sibling page said \"Python only.\"\n\nReport the map before editing anything. \"Three of these six sections duplicate\n`llm-gateway-api-formats`\" is the finding. The restructure is downstream of it.\n\n## Step 3. Assign one home per topic\n\nFor each topic in the map, pick the single page that should own it:\n\n- **Prefer a page that already exists.** A new page is warranted when the topic\n has no home and does not fit an existing one, not when it merely needs\n somewhere to go.\n- **Prefer the page a reader would search for**, not the page the content\n happens to sit on.\n- **Keep the most-linked URL.** Check before choosing, because inbound links\n decide which file survives a merge of two pages:\n\n ```bash\n grep -rn '(/langsmith/llm-gateway)' src/ --include=*.mdx | wc -l\n ```\n\n Folding content *into* the well-linked page and retiring the other one is\n usually cheaper than the reverse.\n\n## Step 4. Cut, do not relocate\n\nA section that duplicates a sibling gets **deleted** and replaced with one\nsentence pointing at the owner. It does not get moved, collapsed into an\naccordion, or shortened in place. An accordion still costs the reader the\ndecision of whether to open it.\n\nContent that has no home yet moves. Content that has one is already written.\n\nWhen you delete a section whose facts differ from the sibling's, the difference\nis a bug in one of them. Resolve it against the source before deleting, or you\nsilently pick a winner. See `docs-edit` for the verification procedure.\n\n## Step 5. Mechanics\n\nRetiring, renaming, or creating a page means navigation entries, redirects, and\ninbound links. `add-docs-page` covers all of it, including the anchor-stability\nand snippet traps. Follow it rather than improvising here.\n\nTwo additional things a restructure breaks that a single-page edit does not:\n\n- **Section anchors other pages link to.** Moving a section moves its anchor.\n Grep for `#the-anchor` across `src/` before the move and repoint every hit. A\n `` or `` can carry an explicit `id` to preserve a landing\n spot that is no longer a heading.\n- **Cross-page pointers that now point at the wrong page.** After moving a\n topic, the sibling pages that used to reference its old location need\n repointing, not just the page you edited.\n\n## Step 6. Verify\n\n```bash\nmake lint_prose FILES=\"\"\nmake build\nmake broken-links-with-anchors\npython3 scripts/check_removed_pages_redirects.py --base-ref origin/main src/docs.json\n```\n\nRead `broken-links-with-anchors` by skipping to the `⎿` lines; those are the\nonly real failures. Compare the count against the same command on `origin/main`\nso a pre-existing baseline is not read as a regression.\n\nThen review the prose with the `docs-review` skill, scoped to the files this\npass changed.\n\n## Step 7. Report what moved\n\nState, per page, what was **deleted**, what **moved**, and what was **added**,\nwith before and after line counts. A restructure that cannot show a page getting\nshorter has not restructured anything, and the line counts are what show the\nreviewer whether it did.\n\nName what you deleted rather than only what you wrote. A reviewer who asked for\na shorter page needs to see the cuts to agree with them.\n\n## Scope\n\nStay inside the page family named in the request. A restructure surfaces\nadjacent problems: stale model IDs, legacy version numbers, and the same\nduplication one directory over. Report them, and **ask before widening the\nsweep.** Fixing sixteen instances across a page family is a reasonable follow-on\ninside one pull request. Fixing six hundred across the corpus is a separate pull\nrequest and probably a tracked issue, because some instances are deliberate and\nsome live in generated files.\n\n## Checklist\n\n- [ ] Page family established from `src/docs.json`, not guessed from filenames.\n- [ ] Duplication map built and reported before any edit.\n- [ ] One owner chosen per topic; most-linked URL identified before merging pages.\n- [ ] Duplicated sections deleted and replaced with a pointer, not relocated.\n- [ ] Conflicting facts between copies resolved against source, not by picking one.\n- [ ] Redirects, nav entries, inbound links, and section anchors all updated.\n- [ ] Verification commands run, `⎿` count compared against `origin/main`.\n- [ ] Report gives per-page before and after line counts.\n- [ ] Anything outside the page family reported, not swept, unless asked.\n","frontmatter":{"name":"docs-restructure","description":"Restructure documentation that spans several pages.

Do not stretch a rule to reach a finding, and do not restructure\n prose that is already fine.\n\n## Step 1. Resolve the target\n\nRun `git fetch origin` first so `main` is current. Resolve in this order:\n\n1. **A number or GitHub PR URL** means a PR. Get the branch with\n `gh pr view --json headRefName`.\n2. **A branch name** is used directly.\n3. **Empty, with uncommitted changes present** means the working tree. Take the\n files from `git status --porcelain` plus\n `git diff --name-only --diff-filter=d origin/main...HEAD`. No checkout, no\n worktree: the files are already in front of you. This is the mode that runs\n after an authoring skill.\n4. **Empty, with a clean tree** means the current `HEAD` against `main`:\n `git diff --name-only --diff-filter=d origin/main...HEAD`.\n\nNarrow to `src/**/*.mdx` and `src/**/*.md`. If nothing changed, say so and stop.\nNever review anything under `build/`.\n\n**For modes 1 and 2, check out the target before inspecting anything.** Your\nworking tree is almost certainly on a different branch, and linting it silently\nreports on the wrong content.\n\nFor a PR, check the branch out in the main working tree so any edit that follows\nlands on the open branch:\n\n```bash\ngit stash list # confirm nothing is about to be lost\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse `git checkout `, not `git checkout -b` or a `--no-track` branch. A\nnew branch is only correct when the review is of `main`, or when the user asks\nfor a separate branch of their own edits. Confirm the checkout by grepping for a\nstring the diff added.\n\nFor a review with no edits to follow, a detached worktree is also fine:\n\n```bash\ngit worktree add --detach /review-wt origin/\n```\n\nDo all reading and linting inside it, and `git worktree remove --force` it when\nthe review is done.\n\nState the target, the resolved SHA or \"working tree\", and the file count before\ngoing further.\n\n## Step 2. Run Vale\n\nRun `make lint_prose FILES=\"\"`, in the main checkout or a worktree alike.\nThe target installs the Vale version pinned in `.mise.toml` into `.bin/vale` when\nit is missing, so a fresh worktree needs no setup beyond network access.\n\nVale is deterministic and CI blocks on it, so its output is not a judgment call.\nReport every violation with its file and line. If invoked with `--fix`, correct\nthem; otherwise list them.\n\nLint the merge-base version of each changed file as well, and report the\ndifference rather than the raw count:\n\n```bash\ngit show origin/main: > /base-\nmake lint_prose FILES=\"/base-\"\n```\n\nA file that already failed on `main` carries pre-existing debt the author did\nnot introduce. A file that was clean on `main` and fails now is this diff's CI\nblocker. Say which one it is, because attribution is the difference between a\nfinding the author has to fix and one they can reasonably decline.\n\nReading the diff text is not a substitute for either run. A patch shows added\nlines without their column offsets or their surrounding component, which is\nexactly what these rules turn on.\n\nVale covers terminology, contractions, first person, future tense, Oxford\ncommas, spaced em dashes, navigation-path arrows, and heading case. **Do not\nspend model judgment re-checking what Vale already checks**, with one exception:\nVale does not scan every part of an MDX file, so a clean run is not proof of\ncompliance. It misses content inside JSX components (``, ``, ``,\n``, ``) and inside table cells. A page can pass Vale with four\nspaced em dashes in it.\n\nGrep the mechanical rules yourself over any file whose diff touches those\nplaces:\n\n```bash\ngrep -nE ' — | – ' # spaced em dashes\ngrep -nEi \"\\b(don't|can't|won't|isn't|it's|you'll)\\b\" # contractions\ngrep -nE '\\b(we|our|us|I)\\b|\\bwill [a-z]+\\b' # first person, future tense\ngrep -n '→' # navigation arrows\n```\n\nReport a hit inside a component the same way you would report a Vale error: it\nwould be one if Vale could see it. A `—` used as an empty table-cell marker is\nfine and is not a finding.\n\n## Step 3. Check structure against the style guide\n\nRead the \"Structure conventions\" section of `AGENTS.md` in the repository root,\nthen check the changed hunks against it. For each finding, quote the rule you are\napplying.\n\nLook for these, and nothing else:\n\n- **A new section or page that does not open with a one-sentence definition** of\n what the thing is or does, followed by the benefit, then the task. Skip when\n the section continues directly from the one above it.\n- **Steps introduced without a colon lead-in**, or steps that are not imperative.\n Skip for a list that is not a procedure.\n- **Three or more options, parameters, or permissions written as prose** where\n `- **Term**: Explanation.` would carry them. Skip for fewer than three.\n- **A feature or class linked on repeat mentions**, or a first mention that is\n not linked. Skip when the repeat is far enough down the page to be a genuine\n re-entry.\n- **A permission, plan tier, or preview requirement stated after the steps it\n governs** rather than before them.\n- **A hard constraint hedged** (\"it is generally not possible to change this\")\n where the guide calls for a flat fact (\"Once set, it cannot be changed.\").\n\nPointer phrasing is deliberately absent from that list. Both the long form (\"For\nmore information, see [Page]\") and the short form (\"See [Page]\") are\nestablished. Do not convert between them in either direction.\n\n## Step 4. Check the style guide items Vale cannot see\n\nRead the \"Style guide\" section of `AGENTS.md`. Vale enforces the mechanical half.\nThese are the rules that need reading:\n\n- **Passive voice** where the actor is known. \"Feedback is treated as a signal\"\n hides who treats it. Skip when the actor is genuinely irrelevant or unknown.\n- **Filler and hedging**: \"Note that\", \"Specifically\", \"simply\", \"easily\",\n \"just\", \"very\", \"basically\", \"obviously\". Cut the word, keep the sentence.\n- **A pronoun, \"this\", or \"the above\" whose antecedent the diff removed.**\n Compression is the usual cause: the noun the sentence refers back to sat in a\n clause the edit cut. Name the thing again.\n- **A condition, default, or requirement the diff shortened away.** Compare the\n hunk against its base rather than reading the new text alone. A sentence that\n got shorter by dropping when the behavior applies, or what value it applies\n to, is a regression, and it lints clean. Quote \"Be concise: cut filler words\n and wordy phrases\" and name the fact the cut removed.\n- **Product versus common noun capitalization.** A capitalized feature name that\n appears nowhere else in the file, or that disagrees with the UI label used\n elsewhere on the same page, is the tell. Grep the file for the term's other\n casings before reporting.\n- **Bold in body text** beyond UI labels. Match what the rest of the page does\n rather than an abstract standard.\n- **Repetition inside the diff.** The same list of items enumerated twice in one\n short section, or a sentence restating the one above it.\n- **Link text** that does not describe its destination, and two different labels\n pointing at the same anchor.\n- **Version minimums written with `>=` in prose.** The convention is \"v0.153.4 or\n later\"; `>=` belongs only in package specifiers such as `langsmith>=0.3.13`.\n\nMeasure before reporting a convention violation. If you are about to say a\nheading form or phrasing is wrong, grep the repository for how often it already\nappears. A form used widely is established practice, not a defect, however much\nthe guide seems to prohibit it. Report the count either way.\n\nA diff can also **leave** a convention rather than break a new one. Lowercasing\nthe explanation in `- **Term**: Explanation.`, dropping a trailing period, or\nswapping a colon lead-in for a dash each reads as a harmless copy edit on its\nown. Compare the before and after of that exact form, then count both spellings\nacross `src/`. When the base was following the majority, the change is the\nfinding.\n\nMeasure the same way when the diff **adopts** a convention rather than breaks\none, because a repeated block has three parts and matching two of them still\nlands wrong:\n\n- **Component.** `` or `` or plain prose.\n- **Wording.** Byte-identical to the siblings, or subtly reworded.\n- **Placement.** Before or after the intro paragraph, relative to imports and\n the first heading.\n\nA status callout copied word for word from the one page in thirteen that puts it\nbelow the intro is a finding, and only a placement count surfaces it. Report the\ncount for each of the three.\n\nWhen the same block appears on three or more pages, say so: it belongs in\n`src/snippets/` rather than duplicated. See `add-docs-page`.\n\n## Step 5. Check the mechanics the diff implies\n\nOnly when the diff triggers them:\n\n- A new page: is it in `src/docs.json`, in the right product, tab, and group?\n- A renamed or deleted page: are inbound links and the `docs.json` entry both\n updated?\n- New internal links: root-relative, and free of `/python/` or `/javascript/`?\n- A new code block: does it carry a real language tag, and are imports sorted?\n- A page or heading that changed URL: is there a redirect?\n\nThe `add-docs-page` skill covers all five in detail. Point at it rather than\nrestating the procedure in a finding.\n\n## Step 6. Report\n\nGroup by file. For each finding:\n\n```txt\nsrc/langsmith/example.mdx:42\nRule: \"State requirements and constraints up front\"\nThe admin permission requirement appears after step 3, but governs all of them.\nSuggested: move it above the numbered list.\n```\n\nEnd with a one-line verdict: what blocks merge (Vale violations, missing nav\nentry, broken link) versus what is a suggestion.\n\nIf nothing turns up, say that plainly. \"No findings\" is a valid and useful\nresult, and is more useful than a manufactured one.\n\n## Running after an authoring skill\n\n`add-docs-page` invokes this skill at its verification step, in working-tree\nmode, on the files it just changed. Two constraints keep that useful:\n\n- **Review finished edits, not drafts.** Findings on a half-written section go\n stale as soon as writing resumes, and reporting them trains the reader to\n ignore the report. Run after the edit is complete and before the commit.\n- **Scope to the files the authoring pass touched.** Do not widen to the rest of\n the branch. If other files changed earlier and also want review, say so and\n let the user ask.\n","frontmatter":{"name":"docs-review","description":"Review changed docs prose against Vale and the AGENTS.md style guide, reporting findings with the rule each one breaks.

Covers sentence length, cross-link density, how to state defaults and conditions, naming exact identifiers, and what to cut in a revision pass. Use when drafting or rewriting a page, a section, a concept overview, a how-to, a callout, or landing copy.\n---\n\n# Write in the house voice\n\n`AGENTS.md` holds the rules a linter can check: no contractions, no first\nperson, no future tense, sentence-case headings, Oxford commas, spacing around\ndashes. Vale enforces most of them and `make lint_prose` is the gate, though\nVale does not scan inside JSX components such as `` and ``, so a\nclean run there proves nothing. This skill covers what a linter cannot check:\nrhythm, density, and the shape of a sentence that carries information.\n\nThe targets below are measured from this repository's own pages, not invented.\n\n## Keep sentences short\n\nMedian sentence length on this site is **13 to 15 words**. Roughly one sentence\nin twelve runs past 25 words, one in forty past 30. Treat 25 as the point where\nyou look for a split and 35 as a defect.\n\nOne idea per sentence. When a sentence carries two, split it and let the second\nstand alone.\n\n> The agent definition selects the model and core capabilities of a managed deep\n> agent.\n\n> Set the `compression` field to control how exported Parquet files are\n> compressed. When omitted, LangSmith uses `zstandard`.\n\nThe second example is two sentences where one long one would have hidden the\ndefault inside a subordinate clause.\n\nThe target is a floor as well as a ceiling. Keep the condition, the actor, and\nthe exact value even when they push a sentence long, and split it rather than\ndropping one of them to get under 15 words.\n\n## Link about half the time\n\nClose to half of all prose sentences here carry a link. Cross-linking is not\ndecoration: it is how a reader escapes a page that does not answer the question\nthey arrived with.\n\nLink a term on first mention only. Pointing forward at the end of a section is\nstandard, and **two pointer forms are both established**:\n\n> Refer to [Spend policies](/langsmith/llm-gateway-spend-policies).\n\n> For the full project layout, see [Project\n> structure](/langsmith/managed-deep-agents-project-structure).\n\nNeither is canonical. Different authors favor different ones, so match the form\nthe page already uses and do not mass-convert one into the other.\n\n## State defaults and conditions as bare facts\n\nPut the trigger first, then the behavior. No hedging, no \"please note\".\n\n> When omitted, LangSmith uses `zstandard`.\n\n> Defaults to the last 7 days, newest first.\n\n> Task planning is opt-in.\n\n> Non-zero exits and timeouts from `--startup-cmd` warn but do not abort the\n> session.\n\nConstraints read the same way, as plain statements of fact rather than warnings\nabout them.\n\n## Name the exact identifier\n\nBacktick every field, flag, value, environment variable, and status. Between a\nquarter and a half of prose sentences on this site contain one. Name the actual\nvalue rather than gesturing at it: `zstandard`, not \"the appropriate\ncompression\"; `CREATED`, `RUNNING`, `COMPLETED`, not \"the various statuses\".\n\n> If your API key is linked to multiple workspaces, specify the workspace in the\n> header with `\"x-tenant-id\"`.\n\n## Reach for a concrete example early\n\n\"For example\" appears in roughly one sentence in thirty, almost always followed\nby a real value rather than a shape.\n\n> For example, in SCIM, the resolved `sub` claim and SCIM `externalId` must\n> match in order for login to succeed.\n\nIf you cannot supply a real example, say less rather than inventing one. Never\nfabricate a field name, a response body, or a policy detail to fill a slot.\n\n## Address the reader, and prefer the active voice\n\nSecond person carries a quarter to a half of sentences, most heavily in\nprocedures and UI steps. Passive voice appears in only about one sentence in\neight, and usually where the actor genuinely does not matter.\n\n> When viewing a trace that was generated by a run in LangSmith, you can access\n> the associated server logs directly from the Details view.\n\nUse the product name as the subject when the reader is not the actor: \"LangSmith\nuses `zstandard`\", not \"we use `zstandard`\".\n\n## Revision pass\n\nRead the draft once looking only for these:\n\n- **Sentences over 25 words.** Split, or cut a clause.\n- **Hedges and filler.** \"simply\", \"just\", \"very\", \"basically\", \"note that\",\n \"be sure to\", \"in order to\", \"has the ability to\". These are near-absent from\n this site's prose, well under one percent of sentences. Delete or replace.\n- **A spaced em dash.** `word — word` fails `LangChain.DashesSpaces` and blocks\n CI. Prefer a comma, a colon, or two sentences, and reach for `word—word` only\n when nothing else reads. A bold label opening a paragraph takes a colon:\n `**Tier assignment**:`, measured at 177 uses in `src/` against 1 for the dash.\n- **A vague identifier** where the exact one belongs.\n- **A cut that took a fact with it.** A tightened sentence that lost its\n condition, its actor, or its exact value reads cleanly and says something\n else. Restore the fact and split the sentence.\n- **A first mention with no link**, and repeat mentions that are linked again.\n- **A claim you did not verify.** Check it against the product source with the\n `verify-against-source` skill, or cut it.

This skill routes a change to the one page that owns it, then edits that\npage without tripping the known Notion failure modes.\n\nRequires the Notion MCP server (`notion-fetch`, `notion-update-page`).\n\n## Rule one: one home per topic\n\nEvery topic lives on exactly one page. Duplicates drift, and drift is worse than\na long page. Before writing anything, search the other four pages for the topic.\nIf it already appears somewhere, update it there instead of adding a second\ncopy.\n\n## Step 1. Route the topic\n\n| Page | ID | Owns |\n|------|----|------|\n| [Docs tooling and agents](https://app.notion.com/p/3ca808527b178153839bff0f2831914c) | `3ca808527b178153839bff0f2831914c` | Parent directory. Page table, \"Owned elsewhere\" list, quick-answers FAQ. |\n| [Docs tech stack](https://app.notion.com/p/30c808527b178073876af57f7d87d8ca) | `30c808527b178073876af57f7d87d8ca` | The production site only: fencing, `src` versus `build`, build pipeline, navigation, integration docs. |\n| [Local setup and quality gates](https://app.notion.com/p/3c8808527b1781dcbaf5d04834a843bf) | `3c8808527b1781dcbaf5d04834a843bf` | mise and prek setup, the `docs` and `mint` CLIs, Vale, git hooks, broken-link triage, the CI matrix, preview deployments, publishing. |\n| [Docs automation and agents](https://app.notion.com/p/3c8808527b17815b81cbf92896b5c3ee) | `3c8808527b17815b81cbf92896b5c3ee` | Scheduled workflows and their cron times, the changelog agents, the #ask-docs intake agent, tracked skills, agent-instruction files, MCP servers. |\n| [Reference docs](https://app.notion.com/p/3c9808527b1781858ebbe92914b02970) | `3c9808527b1781858ebbe92914b02970` | The three LangSmith OpenAPI sources, reference.langchain.com, the `@[ClassName]` link map. |\n\nMost new tooling lands on **Docs automation and agents** (a workflow, script,\nagent, skill, or MCP server) or **Local setup and quality gates** (anything a\ncontributor runs on their own machine or that gates a PR).\n\nThe changelog **system** is not owned by these pages. [LangSmith release\nnotes](https://app.notion.com/p/31b808527b178026943ac2b1ae244021) owns fragments,\nthe fragment schema, and both pipelines. Link to it; do not re-explain it. These\npages keep only the runbook: deployment IDs, HTTP routes, required environment\nvariables, and recovery paths.\n\n## Step 2. Check whether it belongs in Notion at all\n\nDo not write a Notion page for something the repo already documents where people\nfind it. Deliberately excluded: `IDE_SETUP.md`, `.github/brand-guidelines.md`,\n`.github/pull_request_template.md`, `.github/CONTRIBUTING.md`, the issue\ntemplates, and the navigation map, which lives only in `AGENTS.md` because the Notion copy went stale once already.\n\nSkills are the same: a skill is its own authoritative reference. Name it on the\nNotion page, say what it covers and the one or two facts a reader needs in order\nto decide whether to open it, and stop there.\n\nUntracked tooling is not team infrastructure. Anything under a gitignored path\nis personal tooling and does not go on these pages.\n\n## Step 3. Write it\n\nFollow the `docs-team-voice` skill. Do not restate its rules here. The three that\nget missed most often on Notion pages: no first person, no spaced em dashes, and\ndefinition lists written as `- **Term**: Explanation.` with the colon outside the\nbold and a period at the end.\n\nOpen a section with a one-sentence statement of what the thing is, then what it\nenables, then the procedure. Close a substantial page with `## See also`.\n\n## Step 4. Edit safely\n\nFetch the page with `notion-fetch` before every edit. Then use\n`notion-update-page` with `command: \"update_content\"` and narrow\n`content_updates` pairs rather than rewriting the page.\n\nFive failure modes, each of which has already cost a debugging cycle:\n\n- **`old_str` must match the stored indentation exactly.** Tables are stored\n with no leading tabs; callouts do use tabs. A mismatch fails with an\n indentation hint.\n- **Never use `replace_content` on a page holding an uploaded image.** The\n fetched image URL is a short-lived signed S3 link, and rewriting the page body\n can break the image.\n- **A timed-out or async update may already have applied.** Updates default to\n `allow_async: true`. Fetch the page and verify before retrying anything that\n appeared to fail, otherwise the retry duplicates the block.\n- **Bold that contains inline code mid-sentence renders as stray asterisks.**\n Bold wrapping code entirely is fine. Reword so the two do not collide.\n- **In-page anchor links do not resolve.** Notion addresses blocks by ID, not by\n heading slug. Reference sections by name in prose.\n\n## Step 5. Add a row to the Detailed list\n\nThe parent page embeds a **Detailed list** database\n(`collection://3ce80852-7b17-8004-8735-000bc758a8cd`) holding one row per piece\nof tooling. Prose on a page is where someone reads about a thing; this database\nis where they find that it exists at all. It is easy to miss, because the parent\npage renders it as a single inline block.\n\nEvery new workflow, script, skill, agent, MCP server, or git hook gets a row.\nThe schema is Title, Description, Docs page (the URL of the page that explains\nit), Source (the repo paths it lives at), and Type, a select over `GH Actions\n(scheduled)`, `GH Actions (PR/CI)`, `Fleet agent`, `Deep agent`, `External bot`,\n`Skill`, `MCP server`, `Manual script`, and `Git hook`.\n\nQuery it with `notion-query-data-sources` before adding, so a rename becomes an\nupdate rather than a duplicate row. Renaming or moving a file means updating\n`Source` here too, not only in the prose: four rows still pointed at a skills\ndirectory that had been renamed months earlier, and every one of them read as\nplausible.\n\n## Step 6. Close the loop\n\nUpdate the parent page's page table when a page's scope changes, and repoint any\n`## See also` entry that is now wrong. Report which page was edited and what was\ndeliberately left out, so the routing decision is reviewable.\n","frontmatter":{"name":"docs-tooling-notion","description":"Document new or changed docs-team tooling on the Notion tooling pages.

Use when asked to open, create, put up, or submit a docs PR, or after add-docs-page or docs-edit finishes an edit that has no PR yet.\n---\n\n# Open a docs pull request\n\nThis skill starts when the edit is finished and ends when the PR is open and\nits checks are green. Editing a PR that already exists is `docs-edit`, not this\nskill: pushing a second PR against a teammate's work is the failure that skill\nprevents.\n\nThe rules every task follows live in `AGENTS.md`. This skill is the order to\napply them in.\n\n## Step 1. Branch from the latest main\n\nNever commit to `main`. Cut a new branch from a freshly fetched `origin/main`,\nnot from a local `main` that may be days old:\n\n```bash\ngit fetch origin main\ngit switch -c / --no-track origin/main\n```\n\n`--no-track` stops the branch from tracking `origin/main`, so a bare push\ncannot land on `main`.\n\nThe main checkout may be shared with other agent sessions that switch branches\nunder you. Prefer a worktree inside the checkout:\n\n```bash\ngit worktree add -b / --no-track .claude/worktrees/ origin/main\n```\n\nA new worktree's `.mise.toml` is untrusted, so the first commit fails at the\nVale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix. Run `make skills` in the worktree too if you use Claude Code.\n\n## Step 2. Run the gates\n\nRun each gate that applies to the change before committing. CI runs the same\nones, so a skipped gate becomes a red check later.\n\n- **Prose review**: Run the `docs-review` skill on the changed pages. It covers\n the style-guide rules Vale cannot see. Skip it for a change with no prose.\n- **Vale**: `make lint_prose FILES=\"\"`. Fix every error.\n- **Links**: `make broken-links-with-anchors` when links, page names, anchors,\n or `src/docs.json` changed. Read only the indented `⎿` lines.\n- **Code samples**: `make test-code-samples FILES=\"\"` when a\n file under `src/code-samples/` changed.\n- **Pipeline**: `make test` and `make lint` when `pipeline/`, `scripts/`, or\n `tests/` changed.\n\nNote which gates you ran. The PR checklist asks for them.\n\n## Step 3. Commit\n\nStage only the files the change touched, then check that nothing secret is\nstaged:\n\n```bash\ngit diff --cached --name-only\n```\n\nWrite the subject line in the form recent merged PRs use: `docs: ...` for\ncontent, `docs(): ...` when one product is involved, and `chore: ...`\nfor tooling. The body explains why, not what.\n\nDo not add a `Co-Authored-By` trailer for an AI agent. A ruleset on `main`\nrejects the Claude trailer at merge time, and squash merges carry branch commit\ntrailers into `main`.\n\n## Step 4. Write the PR description\n\nUse the sections in `.github/pull_request_template.md`: **Why**, **Changes**,\n**Review notes**, **Related**, and the checklist. Fill each one in, and delete\nany section that would be empty rather than leaving placeholder comments.\n\n- **Why**: The problem the change solves, in two or three sentences.\n- **Changes**: One bullet per meaningful change, naming the file or page.\n- **Review notes**: Where to look hardest, decisions the reviewer may disagree\n with, and every claim you could not verify against source. A preview link\n goes here once the preview deploys.\n- **Related**: Issues, PRs, Linear tickets, and Slack threads. Write\n `Closes [DOC-N]()` to let `sync-linear-issue-from-pr.yml` move\n the Linear issue with the PR.\n- **Checklist**: Tick only what you actually did in Step 2. Leave the rest\n unticked rather than claiming it.\n\nEnd with one plain sentence that discloses AI involvement, for example\n`Prepared with Claude Code.` Do not add the `🤖 Generated with [Claude Code](...)`\nbadge or any similar badge. The `check-pr-ai-attribution` check fails a PR\nwhose description carries one, because the squash merge would copy it into the\ncommit on `main`.\n\nWrite the description to a file and pass it with `--body-file`. A shell\nheredoc inside `--body \"$(...)\"` breaks on apostrophes in some shells.\n\n## Step 5. Push and open the PR\n\nConfirm the remote is a `langchain-ai` repository, then push with an explicit\nremote and branch. Never run a bare `git push`.\n\n```bash\ngit remote get-url origin # must be github.com/langchain-ai/docs\ngit push -u origin \ngh pr create --base main --head --title \"\" --body-file \n```\n\nOpen it as a draft (`--draft`) if it is not ready for review.\n`pr-welcome-comment.yml` requests reviewers from `.github/OWNERS` when the PR\nleaves draft, so do not request reviewers by hand unless asked.\n\nIf you later push more commits, first check that the PR has not merged. A push\nto a merged PR's branch lands nowhere:\n\n```bash\ngh pr view --json state,mergedAt\n```\n\n## Step 6. Watch the checks\n\n```bash\ngh pr checks --watch\n```\n\nFor a failure, read the log with `gh run view --log-failed`, fix the\ncause on the same branch, and push again. Editing the PR description reruns the\ndescription checks without a new commit.\n\nFor same-repo PRs, `create-preview-branch.yml` comments a preview URL. Forks do\nnot get one.\n\n## Step 7. Record tooling changes\n\nWhen the PR adds or changes a script, workflow, Makefile target, check,\nscheduled job, or skill, invoke `docs-tooling-notion` before handing off.\n\n## Report\n\nGive the PR URL, the branch, the gates you ran and their results, the state of\nthe checks, and anything you could not verify.\n","frontmatter":{"name":"open-docs-pr","description":"Open a pull request for finished docs changes.

Small judgment calls belong in the PR diff, not in an issue Q&A thread.\n- **Only** emit `integration-submission-error.md` for hard blockers where no reasonable listing is possible (for example, package missing from the registry, or language/package fields that cannot map to any component).

Correct `integration:` frontmatter. Do **not** set `featured: true` unless a maintainer asked. Remove any duplicate external YAML row for the same package. |\n| **Under 50K**, not featured | **External listing only.** No new hosted MDX. |\n\n## External listing checklist\n\n1. Measure downloads (do not invent counts):\n\n ```bash\n curl -s \"https://pypistats.org/api/packages//overall?mirrors=false\"\n curl -s \"https://api.npmjs.org/downloads/point/last-month/\"\n ```\n\n2. Add YAML under the correct language + component in `scripts/data/integration_external_docs.yaml`:\n\n ```yaml\n - name: ClassOrDisplayName\n pypi: langchain-example # or npm: \"@org/pkg\" under javascript:\n docs_url: https://partner.example/docs\n ```\n\n Prefer the issue `docs_url` when it is an http(s) URL. Verify it returns a successful response when practical.\n\n3. Add a downloads-table row in the matching `src/snippets/oss/*-*-downloads.mdx` with a real `data-sort-value` (not `N/A` when a count is known). Match existing badge markup. For vectorstores/chat, map capability notes to the same ✅/❌ spans neighboring rows use.\n\n4. Add an alphabetical `all_providers` card in `src/oss/python/integrations/providers/all_providers.mdx` and/or the JS providers page when applicable. Use `icon=\"link\"` unless a provider icon already exists. For the card body, use issue `provider_description` after trimming whitespace. If that text is longer than **160 characters** (`PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`), rewrite it to one factual sentence of at most 160 characters before writing the card. Keep product and component names; drop marketing, feature lists, and second sentences. Do not invent capabilities that are not in the original text.\n\n5. Append `packages.yml` when there is a public LangChain-related package and public `owner/repo`. Ensure a trailing newline before appending. Omit `path: .`. Quote `js: \"n/a\"` when there is no JS package.\n\n6. Do **not** add `docs.json` nav entries or redirects for never-shipped pages.\n\n7. Do **not** hand-edit generated overview tables.\n\n8. Run `make lint_prose FILES=\"...\"` on changed MDX when prose changed.\n\n## Hosted guide checklist (≥50K)\n\n1. Copy the matching template under `src/oss/{python,javascript}/integrations//TEMPLATE.mdx`.\n2. Fill only with facts from the package README / partner docs / issue fields. Do not fabricate examples.\n3. Update component index / `docs.json` as other hosted pages do.\n4. Remove a duplicate external YAML row for the same package if present.\n\n## CI / handoff rules\n\n- Leave all changes **uncommitted** in the working tree unless the prompt explicitly says to commit.\n- Do **not** `git push` and do **not** open the PR yourself when running under GitHub Actions; the workflow opens the PR.\n- Do **not** comment on the GitHub issue or PR.\n- Write `integration-submission-error.md` only for hard blockers (see Decision style). Prefer completing a best-effort listing over failing.\n\n## Reference\n\n- External YAML: `scripts/data/integration_external_docs.yaml`\n- Downloads snippets: `src/snippets/oss/*-downloads.mdx`\n- Package registry: `packages.yml`\n- Related skill for converting existing PRs: `update-integrations-prs`\n","frontmatter":{"name":"submit-integration","description":"Create a LangChain docs integration listing from a structured GitHub issue submission (issue form fields as JSON).

Match existing badge markup.\n4. **`all_providers`**: card with external `href` (alphabetical). Use `icon=\"link\"` or an existing provider icon. Card body max **160 characters**. If a draft description is longer, shorten it to one factual sentence ≤160 characters; do not invent claims. Limit: `PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`.\n5. **`packages.yml`**: append only for a public LangChain-related package. Ensure a trailing newline before appending. Omit `path: .`. Skip if the source repo is private or not a normal public VCS listing.\n6. **Nav / redirects**: remove `docs.json` entries and redirects for deleted never-on-main pages.

Do not set `featured: true` unless a maintainer asked.\n3. Prefer `langchain` imports over `langchain_core` when editing kept pages.\n4. For featuring: set `highlight: true` in `packages.yml` only when asked; regenerate overview with the partner package table tool, do not hand-edit `overview.mdx`.\n5. Update `src/docs.json` if adding a page that should stay.\n\n### 5. Commit and handoff\n\n- Conversion commit message focuses on why (threshold / external listing / feature).\n- Show `git diff --stat upstream/main...HEAD` and downloads in the summary.\n- Note `maintainerCanModify` for push later.\n- **Do not push** unless the user asks. Use force-with-lease after rebase when pushing to the PR head.\n- If `maintainerCanModify: false`, say so and ask whether to open a replacement PR.\n\n## Hard rules\n\n- Ask for clarification rather than assuming package identity or feature overrides.\n- Never fabricate download counts, docs URLs, or package names.\n- Never edit `build/`.\n- Never hand-edit generated overview tables.\n- When appending to `packages.yml`, ensure a trailing newline first.\n- Run `make lint_prose FILES=\"...\"` on changed MDX before handoff when prose changed.\n- Follow repo git safety: no bare `git push`; no force to main; no commit unless asked (except when the user said \"go\" / \"next branch\" for this workflow, commit the conversion).\n\n## Common pitfalls\n\n| Pitfall | Fix |\n|---------|-----|\n| Wrong package (similar name on PyPI) | Confirm against install snippets and partner repo |\n| Re-adding Card grids removed on main | Use `IntegrationDownloads` / YAML only |\n| Redirects for never-shipped pages | Delete them |\n| Duplicate table rows | Remove YAML if keeping hosted page |\n| Private source repo | Skip incomplete `packages.yml` entry |\n| JS + Python packages | Add both YAML sections / download rows when both exist |\n\n## Reference\n\n- Eligibility docs: `/oss/contributing/publish-langchain#eligibility-for-hosted-guides`\n- YAML data: `scripts/data/integration_external_docs.yaml`\n- Downloads snippets: `src/snippets/oss/*-downloads.mdx`\n- Package registry: `packages.yml`\n- Policy PR: https://github.com/langchain-ai/docs/pull/4865\n","frontmatter":{"name":"update-integrations-prs","description":"Process open LangChain docs integration PRs against the hosted-guide featuring policy (50K monthly downloads or maintainer feature override).

Covers which repository owns each product, how to reach the private ones, running the part of a sample that needs no API key, and what to say about a claim you could not verify. Use when writing or reviewing a page that asserts how LangChain, LangGraph, Deep Agents, or LangSmith behaves, and when a PR describes behavior without citing where it was checked.\n---\n\n# Verify a claim against the source\n\nThe failure this skill prevents: a page states a default, a precedence order, or\na field name that reads plausibly, passes Vale and the link checker, and is\nwrong. Nothing in CI checks whether a sentence about product behavior is true.\nA reviewer who knows the product catches some of it; the rest reaches readers.\n\nPublished docs, a README, and a model's recollection are all secondary sources.\nPrefer evidence you produced in this session.\n\n## Step 1. Pick the strongest evidence available\n\nWork down this list and stop at the first rung you can actually reach. Each rung\nis weaker than the one above it.\n\n- **Run the sample.** `make test-code-samples`, or scope it with\n `FILES=\"src/code-samples/langchain/foo.py\"`. This is the only method that\n proves a sample works end to end. It needs provider API keys in the\n environment, so it often fails locally and runs in CI instead.\n- **Run the half that needs no model.** Most claims are about a library's\n behavior, not the model's. Stand up the real object in a scratch script and\n print what it returns. A local MCP server, an adapter, a parser, or a store\n needs no API key, and the answer it gives is exact rather than inferred.\n- **Read the library source.** `gh api repos/langchain-ai//contents/\n --jq '.content' | base64 -d`, or `gh api \"search/code?q=+repo:langchain-ai/\"`\n to locate the file first. Settles what a type is, what a default is, and which\n branch actually runs.\n- **Check the installed package.** `uv run python -c \"from x import Y\"` confirms\n an import path resolves at the version this repo pins, which source on `main`\n cannot tell you.\n- **Look up the signature.** The `reference-langchain` MCP server exposes\n `search_api` and `get_symbol` over reference.langchain.com. Right for \"what\n are the parameters of X\", not for \"what does X do at runtime\".\n\n## Step 2. Know which repository owns the claim\n\n| Product | Repository | Where to look |\n|---------|------------|---------------|\n| LangChain | [langchain-ai/langchain](https://github.com/langchain-ai/langchain) | `libs/langchain_v1/langchain/` for v1, `libs/core/` for core, `libs/partners/` for provider packages |\n| LangGraph | [langchain-ai/langgraph](https://github.com/langchain-ai/langgraph) | `libs/langgraph/`, `libs/prebuilt/`, `libs/checkpoint*/`, `libs/cli/`, `libs/sdk-py/` and `libs/sdk-js/` |\n| Deep Agents | [langchain-ai/deepagents](https://github.com/langchain-ai/deepagents) | Also the source of the eval matrix the docs publish |\n| LangSmith SDK | [langchain-ai/langsmith-python](https://github.com/langchain-ai/langsmith-python) and [langchain-ai/langsmith-javascript](https://github.com/langchain-ai/langsmith-javascript) | The Python and JavaScript client libraries |\n| LangSmith platform | langchain-ai/langchainplus (private) | `smith-backend/` (Python API), `smith-go/` (Go services), `smith-frontend/` (UI labels and flows), `host-backend/`, `lc_config/` for settings and their defaults |\n| Agent Server | langchain-ai/langgraph-api (private) | Not in the OSS langgraph repo. Also the source of the Agent Server OpenAPI spec PRs |\n| Helm charts | [langchain-ai/helm](https://github.com/langchain-ai/helm) | `charts/langsmith/values.yaml` for defaults, `templates/_helpers.tpl` for the value-to-environment-variable mapping |\n| OpenEvals | [langchain-ai/openevals](https://github.com/langchain-ai/openevals) | Prebuilt evaluators |\n\nTwo traps worth naming:\n\n- **A private repo is still readable through `gh`.** `gh api` works on\n langchainplus and langgraph-api with the usual credentials. GitHub code search\n is unreliable on the larger ones, so fall back to the git trees API and fetch\n a path directly.\n- **langchain-ai/deployments is archived.** Its GitOps content moved into\n langchainplus. A skill, script, or note that still points at it is stale.\n\nA self-hosted LangSmith claim usually spans two repositories: the chart sets a\nvalue, and the backend decides what to do with it. Check both before describing\nprecedence, because the chart alone does not tell you which setting wins.\n\n## Step 3. Verify the claim, not the sentence\n\nRead the code path that produces the behavior, rather than a name that sounds\nlike it. Three failures that recur:\n\n- **A resolution order inferred from a settings table.** Find the query or the\n conditional that picks a value. An `ORDER BY`, a `COALESCE`, or an `or`\n expression is the precedence; a list of configurable fields is not.\n- **A defensive pattern copied from another sample.** Check whether the guarded\n case can occur. If the constructor only builds an object when a field is\n present, a `.get` with a default is documenting a state that never exists.\n- **A version or model identifier from memory.** Fetch it. The repository's own\n internal consensus is evidence about the repository, not about the provider.\n For model IDs specifically, see the Model references section of `AGENTS.md`.\n\n## Step 4. Record what you checked, and what you could not\n\nName the file and symbol in the pull request body, not just the conclusion. A\nreviewer can then disagree with the evidence rather than with an assertion.\n\nState the gaps in the same place. Common ones that no amount of source reading\ncloses:\n\n- **A UI string.** Source gives you a field and a component; only the running\n product gives you the rendered label. Describe the behavior rather than\n quoting a label you have not seen.\n- **The model-dependent half of a sample.** Say that CI has yet to run it.\n- **A beta surface.** `langchain.mcp` and similar namespaces can move under a\n page that was accurate when written.\n\nWriting \"not verified: the visible label of this control\" is a better outcome\nthan a confident sentence a reader discovers is wrong.\n\n## Related\n\n`AGENTS.md` holds the rules that apply to every edit, including never\nfabricating an example and testing code before publishing it. Use\n`docs-code-samples` when the claim belongs in a runnable sample rather than in\nprose, and `docs-review` for the style pass once the facts are settled.\n","frontmatter":{"name":"verify-against-source","description":"Check that a code sample, API signature, default, or behavior claim in the docs is actually true, by running it or reading the product source.

Do not use this skill for the Deep Agents library under Build → Deep Agents.\n\n## Sources of truth\n\n- Releases: GitHub `langchain-ai/deepagents` via `get_eligible_release` / `get_release_notes`\n- Important: that repo publishes several packages. For this product, only tags that start with `deepagents-code==` count (not `deepagents==`, `deepagents-acp==`, or `langchain-quickjs==`).\n- Docs paths in `langchain-ai/docs`:\n - `src/oss/deepagents/code/` only\n - Navigation for Deep Agents Code in `src/docs.json`\n - Docs style authority: root `AGENTS.md` in `langchain-ai/docs` (read via `get_docs_file` before drafting)\n- Changelog page: `src/oss/deepagents/code/changelog.mdx` (points at the upstream code changelog)\n\nDeep Agents Code pages are unversioned (no Python/TypeScript language split). Conditional fences still resolve against the Python branch.\n\n## What usually needs docs\n\nPrioritize user-facing changes:\n\n- New CLI commands, flags, config keys, or slash commands\n- New providers, plugins, hooks, MCP wiring, or credential flows\n- Approval modes, subagents, sandboxes, or remote sandbox behavior\n- Behavior changes that make existing docs wrong\n- New minimum versions that docs should call out\n\nUsually skip docs for:\n\n- Internal refactors with no user-visible change\n- Dependency bumps with no behavior change\n- Pure bug fixes that do not change documented behavior\n- Changes that belong only to the Deep Agents library (`deepagents==...` releases)\n\nWhen unsure, open a small clarifying ticket/PR only if a reader of the current docs would be misled.\n\n## Workflow for one Deep Agents Code release\n\nThe main agent must run **phase 1** through the `release-research` subagent first (diff + source investigation). This skill guides **phase 2** shipping and judgment details the subagent also uses.\n\n1. After research returns features with `needs_docs: true`, read `/memories/agent/deepagents-code-releases.md` and skip any already recorded for that tag.\n2. Call `get_docs_file` on `AGENTS.md` and read it in full. Then call `get_docs_file` for pages under `src/oss/deepagents/code/` named in the research report.\n3. For each remaining feature:\n - Edit surgically from the page `get_docs_file` content, following the docs repo `AGENTS.md`.\n - Prefer updating the owning page over creating a new page. If a new page is required, also plan the `src/docs.json` navigation update under Deep Agents Code.\n - Load the `ship-docs-update` skill and ship that feature alone with the research report's `evidence` as `evidence_json`.\n4. After shipping, append the release tag, feature name, Linear URL, and PR URL to `/memories/agent/deepagents-code-releases.md`.\n5.

add-docs-page\ndescription: Add, move, rename, or delete a page on the LangChain docs site. Covers choosing the source directory, writing frontmatter, placing the entry in src/docs.json navigation, adding redirects, and verifying with the lint and broken-link gates. Use when asked to add a new doc or page, move or rename a page, put something in the nav, or add a redirect.\nlicense: MIT\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# Add or move a docs page\n\nA page is not finished when the MDX file exists. It also needs a navigation\nentry, and a move or deletion needs a redirect. CI enforces both.\n\nRead `AGENTS.md` for the navigation map, the style guide, and the frontmatter\nrules. This skill covers the procedure around them and does not repeat them.\n\n## Step 1. Choose the source directory\n\nUse the \"Source directory summary\" table in `AGENTS.md` to go from subject to\ndirectory. Two traps:\n\n- Directory names do not match navigation names. `src/langsmith/fleet/` appears\n as \"No-code agents\"; `src/langsmith/managed-deep-agents*.mdx` appears under\n Build, not under a LangSmith menu.\n- Lifecycle menus mix products. Build draws from both `src/oss/` and\n `src/langsmith/`; Test, Deploy, and Monitor all draw from `src/langsmith/`.\n\nNever write to `build/`. It is Mintlify output, regenerated by `make build`.\n\n## Step 2. Write the page\n\nRequired frontmatter:\n\n```yaml\n---\ntitle: Clear, concise page title\ndescription: SEO summary with no markdown, no links, and no backticks\n---\n```\n\nFor OSS pages that differ by language, use `:::python` and `:::js` fences in one\nfile rather than writing two files. The build pipeline emits both versions.\n\nTake every fact on the page from the product source, not from memory, a sibling\ndocs page, or the request that asked for the page. This covers behavior,\ndefaults, field names, version minimums, and examples. Use the\n`verify-against-source` skill to find the repository that owns each claim. Never\nfabricate a value to fill a gap. Leave the claim out, and list what you could\nnot confirm in the pull request body and in your reply to the requester.\n\n## Step 3. Add the navigation entry\n\nNavigation lives in `src/docs.json` under `navigation.products`. There are two\nproducts: `products[0]` is AGENT DEVELOPMENT LIFECYCLE (Home, Build, Test,\nDeploy, Monitor) and `products[1]` is PRODUCTS AND SETUP (LangSmith setup, LLM\nGateway, No-code agents, Engine, Deep Agents Code).\n\nEach menu item is addressed by its `item` key, then nests one of two ways:\n\n- `menu[].tabs[].pages[]` for most menu items.\n- `menu[].dropdowns[].tabs[].pages[]` for Build, which has Python and\n TypeScript dropdowns.\n\nA `pages` array holds page-path strings and `{\"group\": ..., \"pages\": [...]}`\nobjects, nested to any depth.\n\nThree rules:\n\n1. **A language-versioned OSS page needs two entries.** Build page paths carry\n the language segment (`oss/python/deepagents/overview` and\n `oss/javascript/deepagents/overview`), so one new page means one entry in the\n Python dropdown and one in the TypeScript dropdown. Omitting the TypeScript\n entry is the most common miss.\n2. **Page paths omit the `src/` prefix and the file extension.**\n `src/langsmith/sandboxes.mdx` is `\"langsmith/sandboxes\"`.\n3. **A new group leads with an index page:**\n `\"pages\": [\"group/index\", \"group/page\"]`.\n\nIntegration pages are the exception. Add them to the component's `index.mdx`\ninstead, and touch `docs.json` only when creating a brand-new component group.\n\n## Step 4. Add redirects for a move, rename, or deletion\n\nFor a move or rename of a file that was already on `main`, run the repo's mover first. It rewrites cross-references\nacross the corpus, which hand-editing misses: every link to the page in every\nform (`/oss/langchain/x`, `/oss/python/langchain/x`, `href=\"...\"`), plus the\n`src/docs.json` nav entries and redirect destinations that name it:\n\n```bash\nuv run docs mv src/langsmith/old-name.mdx src/langsmith/new-name.mdx --dry-run\n```\n\nRead any `Left ... links unchanged` warning in the output. It marks links the\nmover could not rewrite safely, such as an unversioned `/oss/integrations/...`\nlink that also reaches the other language's page. Fix those by hand.\n\nDrop `--dry-run` once the preview looks right. The mover does not add a\nredirect, so add one to the `redirects` array in `src/docs.json`:\n\n```json\n{ \"source\": \"/langsmith/old-name\", \"destination\": \"/langsmith/new-name\" }\n```\n\nRedirect paths are site paths and start with `/`. A language-versioned page\nneeds a redirect per language, plus one for the unversioned path if the old URL\nhad one.\n\n`scripts/check_removed_pages_redirects.py` runs in CI and fails the PR when a\npage leaves the navigation and its source file is gone with no redirect. The\nsame script fails when `docs.json` names a page whose file does not exist, so a\ntypo in a page path is caught there rather than at build time.\n\n## Step 4b. Two traps that fail silently\n\n### Extract a snippet once a block appears on three pages\n\n`AGENTS.md` covers how to add a snippet. The rule for **when**: the same block\nrepeated on three or more pages becomes one file under `src/snippets/`. A status\ncallout duplicated across a page family means the wording change that retires it\nis an edit to every page in the family, and one will be missed.\n\nVerify a new snippet reaches the build. The pipeline rewrites snippet imports to\nlanguage-specific paths, so `/snippets/langsmith/x.mdx` becomes\n`/snippets/python/langsmith/x.mdx` in the output, and a missing target renders as\nnothing at all rather than as an error:\n\n```bash\nls build/snippets/python/langsmith/.mdx build/snippets/javascript/langsmith/.mdx\n```\n\n### Editing a heading moves its anchor\n\nA heading's slug is derived from its text, so rewording one silently breaks every\n`#anchor` link pointing at it, including links from other pages and entries in\n`src/docs.json`. Grep before editing:\n\n```bash\ngrep -rn 'use-with-the-langsmith-gateway' src/ --include=*.mdx --include=*.json\n```\n\nChanging only capitalization is safe, because slugs are lowercased. Changing a\nword is not, and needs either a reworded inbound link or a redirect.\n`` and `` accept an explicit `id`, which is how to keep a\nlanding spot that is no longer a heading.\n\n## Step 5. Verify\n\nRun all three, in this order:\n\n```bash\nmake lint_prose FILES=\"src/path/to/page.mdx\"\nmake build\nmake broken-links-with-anchors\n```\n\nWhen `make build` fails with `Required uv version >=0.9.26 does not match the\nrunning version`, the local `uv` has drifted from the one `pyproject.toml`\nexpects. Run the pipeline directly rather than working around the build:\n\n```bash\nPYTHONPATH=\"$(pwd)\" .venv/bin/python -m pipeline build\n```\n\nA fresh git worktree has no `.venv`, and the same version check blocks\n`uv sync` from creating one. Point at the main checkout's interpreter instead;\n`PYTHONPATH` still loads the pipeline code from the worktree:\n\n```bash\nPYTHONPATH=\"$(pwd)\" /.venv/bin/python -m pipeline build\n```\n\nA fresh worktree's `.mise.toml` is also untrusted, so the first commit fails\nat the Vale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix.\n\n`make broken-links-with-anchors` depends on `build`, so it fails the same way.\nIts link-check half runs on its own once the build output exists:\n\n```bash\ncd build && mint broken-links --check-anchors | tee /tmp/bl.txt\ncd .. && python3 scripts/filter_mint_broken_links.py --check-anchors --input /tmp/bl.txt\n```\n\nRead `make broken-links-with-anchors` output by skipping to the `⎿` lines. Those are the only\nreal failures. A bare filename with no indented lines beneath it is an\nOpenAPI-generated page that exists at deploy time but not locally.\n\nFix every Vale finding. CI blocks on `lint_prose`, and its most common failure is\na spaced em dash (`word — word` must be `word—word`).\n\n## Step 6. Review the prose\n\nOnce the edit is complete and before committing, invoke the `docs-review` skill\non the files this pass changed. It runs in working-tree mode, so it needs no\ncheckout, and it covers the style-guide rules Vale cannot see: passive voice,\nfiller, product versus common noun capitalization, structure conventions, and\nlink text.\n\nRun it on finished edits only. A review of a half-written section produces\nfindings that go stale as soon as writing resumes.\n\nSkip this step for a change too small to have prose in it, such as a pure\n`docs.json` reorder or a redirect-only fix.\n\n## Step 7. Open the pull request\n\nFollow the `open-docs-pr` skill to commit, write the PR description, push, and\nwatch the checks. If the change belongs on an existing PR, use `docs-edit`\ninstead.\n\n## Checklist\n\n- [ ] File in the directory the source-directory table names, not `build/`.\n- [ ] Frontmatter present, `description` free of markdown.\n- [ ] Every claim checked against product source; unconfirmed claims cut and\n listed in the PR body.\n- [ ] `src/docs.json` entry in the right product, menu item, tab, and group.\n- [ ] Both language entries added if the page is language-versioned.\n- [ ] Index page first if a new group was created.\n- [ ] Redirect added for every moved, renamed, or deleted path.\n- [ ] Inbound `#anchor` links checked before any heading was reworded.\n- [ ] A block now on three or more pages extracted to `src/snippets/`, and its\n built `python/` and `javascript/` targets confirmed to exist.\n- [ ] `make lint_prose` clean, `make broken-links-with-anchors` shows no new `⎿` lines.\n- [ ] `docs-review` run on the changed files, findings addressed.\n- [ ] PR opened with `open-docs-pr`, checks green.\n\n\n---\nname: docs-code-samples\ndescription: Use this skill when migrating inline code samples from LangChain docs (MDX files) into external, testable code files that are extracted by this repo’s snippet scripts and used as Mintlify snippets. Applies when extracting code blocks from documentation, creating runnable code samples, using snippet delineators, or wiring snippet output into MDX includes.\nlicense: MIT\ncompatibility: LangChain docs monorepo with Mintlify. Requires Python and Make (Node.js is also required for TypeScript samples).\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# docs-code-samples\n\n## Overview\n\nThis skill documents the workflow for moving inline code samples from LangChain documentation into standalone, testable files that this repo extracts into snippets for use in MDX using Mintlify.\n\n## When to use\n\n- Migrating inline Python, TypeScript/JavaScript, or Java code blocks from MDX to external files\n- Creating runnable, testable code samples for documentation\n- Setting up snippet extraction and Mintlify snippet includes\n\n## Directory structure\n\nCode samples live under `src/code-samples/` in folders that match the product:\n\n- `langchain/` — LangChain docs\n- `langgraph/` — LangGraph docs\n- `deepagents/` — Deep Agents docs\n- `langsmith/` — LangSmith docs\n\nExample:\n\n```\nsrc/\n├── code-samples/ # Source: testable code with snippet tags\n│ ├── langchain/\n│ │ ├── return-a-string.py\n│ │ └── return-a-string.ts\n│ ├── langgraph/\n│ │ ├── langgraph-sql-agent.py\n│ │ └── langgraph-sql-agent.ts\n│ ├── deepagents/\n│ │ └── example-skill.py\n│ └── langsmith/\n│ ├── trace-example.py\n│ └── trace-example.java\n├── code-samples-generated/ # Snippet output (gitignored)\n│ ├── return-a-string.snippet.tool-return-values.py\n│ ├── return-a-string.snippet.tool-return-values.ts\n│ └── ...\n└── snippets/\n └── code-samples/ # MDX snippets for docs (all products)\n ├── tool-return-values-py.mdx\n ├── tool-return-values-js.mdx\n └── ...\n```\n\n**Prefer one file per doc page or topic**: Collocate related snippets in a single code sample file whenever they belong to the same MDX page, tutorial flow, or feature (for example, setup plus invocation, or a do/don't pair). Use multiple `:snippet-start:` / `:snippet-end:` pairs in that file rather than splitting into several `.py` or `.ts` files. Reserve separate files for unrelated samples or when a page genuinely needs independent test entry points.\n\n**More than one snippet in one file**: A single code sample file can contain more than one named snippet using different `:snippet-start: snippet-name` and `:snippet-end:` pairs. Each snippet must have a unique name. Shared imports, helpers, and `:remove-start:` test harness code live once in the file; only the fenced regions between snippet tags appear in the generated MDX snippets.\n\n**When to split TypeScript samples into separate files**: Python samples can usually keep multiple snippets in one file because later definitions overwrite earlier ones at module scope. TypeScript and JavaScript cannot: `make test-code-samples` runs the entire `.ts` file, and every snippet's code executes in the same module scope. Split into separate `.ts` files when snippets would collide, for example:\n\n- Duplicate `import` bindings (for example two snippets both `import { interrupt } from \"@langchain/langgraph\"`)\n- Duplicate `const` / `let` / `class` / `function` declarations with the same name (for example two snippets both declare `const State = ...`)\n- Two self-contained snippets that each need their own imports and top-level setup\n\nKeep related snippets in one Python file when possible. For TypeScript, use one file per independently runnable snippet when imports or top-level bindings would conflict. Name sibling files clearly, for example `langgraph-interrupts-validate-conditional-edge-pattern.ts` and `langgraph-interrupts-validate-conditional-edge.ts`. Put shared test-only setup in `:remove-start:` blocks inside each file rather than importing between sample files.\n\nWithin a single TypeScript file, `:remove-start:` blocks and snippet regions share the same module scope when `make test-code-samples` runs the file. Do not import the same binding in both places. Keep imports that appear in the docs snippet inside the snippet; limit `:remove-start:` imports to symbols used only by the test harness (for example `Command`, `MemorySaver`) that the snippet does not import.\n\n## Step-by-step instructions\n\n### 1. Create the code sample file\n\nPlace the file under `src/code-samples/` in the folder for the product: `langchain/`, `langgraph/`, `deepagents/`, or `langsmith/` (for example, `src/code-samples/langgraph/langgraph-sql-agent.py` for LangGraph docs).\n\nUse a descriptive filename, for example, `return-a-string.py`, `return-a-string.ts`, or `traceable-pipeline.java`. When a doc page needs several code blocks for the same feature, add them as multiple snippets in one Python file (for example, `rubric-configure.py` with `rubric-configure-py` and `rubric-invoke-py`) instead of creating `rubric-configure.py` and `rubric-invoke.py`. For TypeScript, use one file per snippet when module-scope imports or bindings would conflict (see **When to split TypeScript samples into separate files** above).\n\n### 2. Add snippet delineators\n\nWrap the code that should appear in the docs with snippet tags:\n\n**Python:**\n```python\n# :snippet-start: snippet-name-py\nfrom langchain.tools import tool\n\n@tool\ndef get_weather(city: str) -> str:\n \"\"\"Get weather for a city.\"\"\"\n return f\"It is currently sunny in {city}.\"\n\n# :snippet-end:\n```\n\n**TypeScript/JavaScript:**\n```ts\n// :snippet-start: snippet-name-js\nimport { tool } from \"langchain\";\n// ... tool definition ...\n// :snippet-end:\n```\n\n**Java:**\n```java\n// :snippet-start: snippet-name-java\npublic class Example {\n public static void main(String[] args) {\n System.out.println(\"hello\");\n }\n}\n// :snippet-end:\n```\n\n**Go:**\n```go\n// :snippet-start: snippet-name-go\npackage main\n\nimport \"fmt\"\n\nfunc main() {\n\tfmt.Println(\"hello\")\n}\n// :snippet-end:\n```\n\n**Bash (cURL):**\n```bash\n# :snippet-start: snippet-name-sh\ncurl \"https://api.smith.langchain.com/api/v1/runs\" \\\n -H \"x-api-key: $LANGSMITH_API_KEY\"\n# :snippet-end:\n```\n\nChoose a unique `snippet-name` in kebab-case. All snippet names must include a language suffix: `-py` for Python files, `-js` for TypeScript/JavaScript files, `-java` for Java files, `-kt` for Kotlin files, `-go` for Go files, and `-sh` for bash/cURL files (for example, `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh`). This becomes the base of the output filename.\n\n### 3. Add runnable test code in remove blocks\n\nWrap any code that makes the sample executable but should not appear in docs.\n\n**Run snippet code before exiting.** `make test-code-samples` must execute the snippet body, not skip it. Do not put `raise SystemExit(0)`, `process.exit(0)`, or `exit 0` at the top of a file (or before `:snippet-start:`) so the test passes without running imports, constructors, or API calls. That only checks that the file parses; it does not validate function signatures, option shapes, or import paths.\n\nPlace `:remove-start:` blocks **after** the snippet when you can, so the harness runs assertions on values the snippet created:\n\n**Python (preferred):**\n```python\n# :snippet-start: example-py\nfrom deepagents import create_deep_agent\n\nagent = create_deep_agent(model=\"google_genai:gemini-3.6-flash\")\n# :snippet-end:\n\n# :remove-start:\nassert agent is not None\nprint(\"✓ example validated\")\n# :remove-end:\n```\n\n**TypeScript (preferred):**\n```ts\n// :snippet-start: example-js\nimport { DeepAgentsServer } from \"deepagents-acp\";\n\nconst server = new DeepAgentsServer({\n agents: { name: \"careful-agent\", interruptOn: { write_file: true } },\n});\n// :snippet-end:\n\n// :remove-start:\nif (!server) throw new Error(\"server not created\");\nconsole.log(\"✓ example validated\");\n// :remove-end:\n```\n\nFor samples whose docs show a blocking tail (for example `await server.start()`, `asyncio.run(main())`, or `agent.invoke()` with a live model), keep setup and construction in the snippet so types and signatures are checked, then move **only** the blocking call into a trailing `:remove-start:` block—or omit it when construction alone is enough:\n\n```python\n# :snippet-start: server-example-py\nserver = AgentServerACP(agent)\n# :snippet-end:\n\n# :remove-start:\n# Do not call await run_agent(server) here — it blocks on stdio.\nassert server is not None\nprint(\"✓ server-example validated\")\n# :remove-end:\n```\n\n**Do not** short-circuit before the snippet:\n\n```python\n# :remove-start:\nraise SystemExit(0) # BAD: snippet below never runs\n# :remove-end:\n\n# :snippet-start: example-py\n...\n```\n\nThe examples below show harness code that invokes behavior when the snippet defines callable helpers:\n\n**Python:**\n```python\n# :remove-start:\nif __name__ == \"__main__\":\n result = get_weather.invoke({\"city\": \"San Francisco\"})\n assert result == \"It is currently sunny in San Francisco.\"\n print(\"✓ Tool works as expected\")\n# :remove-end:\n```\n\n**TypeScript:**\n```ts\n// :remove-start:\nasync function main() {\n const result = await getWeather.invoke({ city: \"San Francisco\" });\n if (result !== \"It is currently sunny in San Francisco.\") {\n throw new Error(`Expected \"...\", got \"${result}\"`);\n }\n console.log(\"✓ Tool works as expected\");\n}\nmain();\n// :remove-end:\n```\n\nThe extraction script strips `:remove-start:` / `:remove-end:` content when extracting snippets.\n\n### 4. Test the code sample\n\nBefore extracting snippets, verify the code sample runs correctly:\n\n```bash\n# Test the file(s) you added (faster)\nmake test-code-samples FILES=\"src/code-samples/langchain/return-a-string.py\"\n\n# Or run all code samples\nmake test-code-samples\n```\n\nFor multiple files: `FILES=\"path1 path2\"`. Fix any failures before proceeding—do not extract snippets until the samples pass.\n\nTo run one product's samples, set `CODE_SAMPLE_PATHS` to space-separated directories under `src/code-samples/`, for example `CODE_SAMPLE_PATHS=\"src/code-samples/langsmith\" make test-code-samples`. It also narrows an explicit `FILES` list. CI runs one matrix leg per product this way (`oss` covers `langchain/`, `langgraph/`, and `deepagents/`; `langsmith` covers `langsmith/`), so a failure in one product never turns the other product's check red. A new top-level directory under `src/code-samples/` must be added to a leg in `.github/workflows/test-code-samples.yml`, or the workflow fails its coverage check.\n\nJava files (`.java`) under `src/code-samples/` are run using `jbang`. To keep CI green, Java samples must:\n\n- Print at least one line of output so it's obvious the sample ran\n- Exit successfully (code 0) when optional API keys are not set, for example:\n - `OPENAI_API_KEY` for LLM calls\n- Fail fast (non-zero exit) when a key is required for the sample to run, for example `manage-prompts-0-push.java` without `LANGSMITH_API_KEY`\n\n`make test-code-samples` runs every `.java` file under `src/code-samples/` in **lexical path order** (after all Python and TypeScript samples). That order is unrelated to section order in the docs. If one sample must run before another (for example creating a hub prompt before pulling it), name the source files so they sort correctly. For example, `manage-prompts-pull.java` runs before `manage-prompts-push.java` because `pull` sorts before `push`; use prefixes such as `manage-prompts-0-push.java` and `manage-prompts-1-pull.java` when you need push to run first.\n\nGo files (`.go`) under `src/code-samples/` are run with `go run` from `src/code-samples/`, which shares a single `go.mod`/`go.sum` at that directory (add new dependencies there with `go get`, then `go mod tidy`, similar to how `.ts` samples share `src/code-samples/package.json`). `go run .go` only compiles that one file, not its sibling files in the same directory, so — like Kotlin — put each snippet variant in its own file (`topic-before.go`, `topic-after.go`) rather than multiple snippets sharing one file: two files in the same package cannot both declare `func main()`. Go samples do not guard on missing keys — let the SDK call fail fast (matching Python's behavior) rather than skipping with a printed message. `make test-code-samples` runs `.go` files last, after Kotlin, in lexical path order.\n\nBash/cURL files (`.sh`) under `src/code-samples/` are run with `bash .sh` from `src/code-samples/`. Like Go, put each snippet variant in its own file (`topic-before.sh`, `topic-after.sh`) rather than sharing one file. Hide test-only setup (`#!/usr/bin/env bash`, `set -euo pipefail`, resolving a real ID/value for a `` shown in the docs) in `# :remove-start:`/`# :remove-end:` blocks so the visible snippet is exactly the illustrative curl command a reader would copy — including no shebang or `set -e` line. `curl` does not exit non-zero on an HTTP error status by itself, so when a script pipes a response into `jq` to extract a value used by a later request (for example resolving a project ID), add a hidden check that the resolved value is non-empty and not the literal string `null` before continuing, so a bad API response fails the test loudly instead of silently propagating into later requests. `make test-code-samples` runs `.sh` files last, after Go, in lexical path order.\n\nCheck formatting with:\n\n```bash\nmake lint\n```\n\nFix any ruff or mypy issues before proceeding. Run `make format` to auto-fix formatting.\n\n### 5. Run snippet extraction\n\nFrom the repo root:\n\n```bash\nmake code-snippets\n```\n\nTo limit extraction to specific samples (faster while iterating), set `CODE_SNIPPET_SOURCES` to space-separated repo-relative paths under `src/code-samples/`:\n\n```bash\nCODE_SNIPPET_SOURCES=\"src/code-samples/langsmith/trace.java\" make code-snippets\n```\n\nThis command:\n\n1. Runs `python scripts/extract_code_snippets.py` (line-based, Bluehawk-compatible; handles `/**` in TS strings). Optional env `CODE_SNIPPET_SOURCES` limits extraction to specific paths under `src/code-samples/`; other stems already in `src/code-samples-generated/` are left alone.\n2. Runs `scripts/generate_code_snippet_mdx.py` to produce MDX snippets in `src/snippets/code-samples/` (always regenerates MDX from everything under `src/code-samples-generated/`)\n\nOutput files:\n\n- `return-a-string.snippet.tool-return-values.py` → `tool-return-values-py.mdx`\n- `return-a-string.snippet.tool-return-values.ts` → `tool-return-values-js.mdx`\n\n### 6. Update the MDX file to use the snippet\n\nAdd an import at the top of the MDX file (after frontmatter):\n\n```mdx\nimport ToolReturnValuesPy from '/snippets/code-samples/tool-return-values-py.mdx';\nimport ToolReturnValuesJs from '/snippets/code-samples/tool-return-values-js.mdx';\n```\n\nReplace the inline code blocks with the snippet components:\n\n```mdx\n:::python\n\n\n\n:::\n\n:::js\n\n\n\n:::\n```\n\n## Naming conventions\n\n| Element | Convention | Example |\n|--------|-------------|---------|\n| Code file | Descriptive, kebab-case | `return-a-string.py`, `return-a-string.ts`, `traceable-pipeline.java`, `traceable-pipeline.kt`, `traceable-pipeline.go`, `traceable-pipeline.sh` |\n| Snippet name | Kebab-case with language suffix: `-py` for Python, `-js` for JS/TS, `-java` for Java, `-kt` for Kotlin, `-go` for Go, `-sh` for bash/cURL | `tool-return-values-py`, `tool-return-values-js`, `traceable-pipeline-java`, `traceable-pipeline-kt`, `traceable-pipeline-go`, `traceable-pipeline-sh` |\n| MDX snippet (Python) | `{snippet-name}.mdx` (snippet name ends in `-py`) | `tool-return-values-py.mdx` |\n| MDX snippet (JS) | `{snippet-name}.mdx` (snippet name ends in `-js`) | `tool-return-values-js.mdx` |\n| Component name | PascalCase | `ToolReturnValuesPy`, `ToolReturnValuesJs` |\n\n## Script behavior\n\n`scripts/generate_code_snippet_mdx.py`:\n\n- Reads `*.snippet.*.py` and `*.snippet.*.ts` from `src/code-samples-generated/`\n- Wraps content in fenced code blocks (`` ```python `` or `` ```ts ``)\n- When a snippet contains a model string, expands it into a Mintlify `` with the seven quickstart provider tabs (Google, OpenAI, Anthropic, OpenRouter, Fireworks, Baseten, Ollama):\n - Python: `model=\"…\"` or `model = \"…\"`\n - TypeScript: `model: \"…\"` or `model = \"…\"` (including `let model = \"…\"`)\n - Only the quoted model ID is swapped per tab, so assignment vs property syntax is preserved\n - Put `# KEEP MODEL` / `// KEEP MODEL` on the line before a model string to leave that occurrence unchanged\n- Writes to `src/snippets/code-samples/{snippet-name}-py.mdx` or `-js.mdx`\n\nTo support additional languages, add config entries in that script.\n\n## Guidelines\n\n- **Prefer the plainest thing that runs.** Keep the snippet verbatim from the page, add hidden harness code only where CI differs from a reader's machine (a missing env var, a dataset name that must be cleared first), and do not add options, inputs, or indirection nobody asked for. The same applies to the runner and workflow around the samples: one job per product, re-run a job from the GitHub UI rather than adding an input for it, read what GitHub already knows (job names, conclusions) rather than passing artifacts around. If a change needs a diagram to explain, it is too much.\n- **Run snippet code in tests** — `:remove-start:` harnesses must not exit before the snippet runs. Let imports, constructors, and configuration execute so `make test-code-samples` catches wrong signatures, renamed options, and broken import paths. Put `SystemExit` / `process.exit` only after the snippet (or use them to skip a trailing blocking call such as `server.start()`, not the whole sample).\n- **Collocate related snippets** in one code sample file per doc page or feature when possible (Python and Java). Import each generated MDX snippet separately in the MDX file (for example, `` then `` from the same source file). For TypeScript, split into separate `.ts` files when snippets duplicate imports or top-level bindings; still import each generated MDX snippet in the MDX file the same way.\n- Do not mock LangChain internals (for example `unittest.mock.patch` on `init_chat_model` helpers) so that imports resolve real chat model instances. Do not use fake chat models in docs code samples (for example `GenericFakeChatModel`, `FakeListChatModel`, or other `langchain_core` testing fakes). Wire a real chat model (for example `ChatOpenAI`) so snippets match what readers run; `make test-code-samples` requires a valid API key when the sample calls the model.\n- Do not change `pyproject.toml` when making code sample changes.\n- Always run `make test-code-samples FILES=\"path/to/your/file.py\"` before `make code-snippets` to ensure new samples pass.\n- Run `make lint` once the code sample is written; fix any issues (or run `make format` to auto-fix).\n- Do not add code samples to linting ignore rules when making lint-related changes—fix the code instead.\n- `src/code-samples-generated/` is gitignored; regenerate with `make code-snippets`, narrowing to specific files with `CODE_SNIPPET_SOURCES` while iterating.\n- Reference `AGENTS.md` for docs style and rules.\n- Use `:::python` and `:::js` fences for language-specific content; the build produces separate Python and JavaScript doc versions.\n- For python tests, try to correct the type rather than adding `# type: ignore[arg-type]`\n\n\n---\nname: docs-edit\ndescription: Edit a docs page that already has an open pull request, or revise a page in place. Covers checking out the PR's own branch instead of cutting a new one, forked cross-repository PRs, reading the real diff, checking the edit against related pages, and the verification to run before handing off. Use when asked to edit, revise, fix, or review changes on a named PR, branch, or existing page.\n---\n\n# Edit an existing docs page or PR\n\nThe failure this skill prevents: an agent asked to \"fix the wording on PR 1234\"\ncuts a fresh branch, commits there, and opens a second pull request against a\nteammate's work. Land edits on the branch that already exists.\n\n## Step 1. Check out the PR's own branch\n\nWhen the request names a PR, by number or URL, work on that PR's head branch.\n\n```bash\ngh pr view --json number,title,headRefName,baseRefName,author,isCrossRepository,files\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse plain `git checkout `. Do not use `git checkout -b` or `--no-track`:\neach produces a net-new branch, and committing there opens a second PR against\nsomeone else's work.\n\nA worktree on the PR's own branch is fine, and safer when other sessions share\nthe main checkout. Pass the existing branch name, never `-b`:\n\n```bash\ngit fetch origin \ngit worktree add # tracks origin/\n```\n\nThis fails if the branch is already checked out in another worktree. Use that\nworktree instead of forcing a second one.\n\nmise trusts config files by path, so each new worktree's `.mise.toml` starts\nout untrusted. The Vale pre-commit hook runs through `mise exec`, and the first\ncommit fails with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree, then commit again. To stop this\nfor good, add the main checkout to `trusted_config_paths` in\n`~/.config/mise/config.toml`. It trusts every worktree created inside the\ncheckout, such as `.claude/worktrees/*`, but not sibling directories.\n\nA local branch whose name merely mentions the PR is not the same branch. Confirm\nthat `git rev-parse HEAD` matches the `headRefOid` from `gh pr view` before\nediting, and that the branch has an upstream:\n\n```bash\ngit rev-parse --abbrev-ref @{upstream} # fails when the branch tracks nothing\n```\n\nCut a new branch only when the edits are your own and no open PR exists to land\nthem on, or when the user asks for one. Branch from the latest `origin/main`,\nnever from a stale local `main`.\n\n### Cross-repository PRs\n\nWhen `isCrossRepository` is `true`, the branch lives on a fork. Use `gh pr\ncheckout `, which configures the fork remote, and confirm push access before\ncommitting. Without it, the edits are stranded locally.\n\n## Step 2. Read the real diff\n\n```bash\ngh pr diff \n```\n\nPrefer this over `git diff main...HEAD`. A stale local `main` silently inflates\nthat diff with unrelated commits, and a branch that already merged `main` once\ninflates it further. To compare against the live base instead, fetch first and\nuse `git diff origin/main...HEAD`.\n\n## Step 3. Edit\n\n`AGENTS.md` holds the rules that apply to every edit: the style guide,\nfrontmatter, syntax, and the navigation map. Two that matter most here:\n\n- Match the conventions of the file you are editing. Do not restructure,\n combine, or split pages unless asked.\n- Never fabricate examples, field names, UI labels, or policy details. Verify\n each factual claim against the source it describes, and state plainly what you\n could not verify.\n\nFor voice and sentence rhythm while drafting, use the `docs-team-voice` skill. For\nadding, moving, renaming, or deleting a page, including navigation and\nredirects, use `add-docs-page`. When the edit is really a question of which page\nthe content belongs on, use `docs-restructure`.\n\n### Verify claims against source, not against other docs\n\nA sibling docs page is not a source. It is another claim, written by someone who\nmay have been guessing too, and two docs pages that agree can both be wrong.\nCheck the implementation:\n\n```bash\ngh api -X GET search/code -f q='LANGSMITH_GATEWAY repo:langchain-ai/langchain' \\\n --jq '.total_count, (.items[]?|.path)'\ngh api repos/langchain-ai/langchain/contents/ --jq .content | base64 -d\n```\n\nPython and TypeScript live in separate repositories and drift apart, so a table\nwith a Python column and a TypeScript column needs both checked:\n`langchain-ai/langchain`, `langchain-ai/langchainjs`, and for some providers a\ndedicated repository such as `langchain-ai/langchain-google`. A package's\n`CHANGELOG.md` gives the version a feature landed in, which is what a minimum\nversion column needs.\n\nState plainly what you could not verify. \"I could not confirm the Baseten row;\nno gateway references in either candidate repository\" is a useful review note.\nSilently keeping an unverified claim is not.\n\n### Read the pages around the one you are editing\n\nA page is one of several that cover the same feature. Others reach it from\nanother angle: a CLI reference, a permissions table, a list of Chat surfaces, a\nsetup guide, the pages that link to it. An edit made to one page in isolation\nleaves the set contradicting itself.\n\nBefore editing, find the related pages:\n\n```bash\ngrep -rliE \"|\" src --include='*.mdx'\ngrep -n \"\" src/docs.json\n```\n\nRead each one, then check for:\n\n- **Contradictions.** The edited page and a related one give different setup\n steps, defaults, or requirements. For example, a feature page that sets\n `LANGSMITH_API_KEY` while the CLI page recommends `langsmith auth login`.\n Settle it against source, then fix whichever page is wrong.\n- **Duplication.** A procedure the edited page restates from the page that owns\n it. Link to the owner instead. When choosing the owner is the real question,\n use `docs-restructure`.\n- **Missing entry points.** A page that lists every surface, command group, or\n permission area of a product should mention the feature and link to it.\n- **Navigation placement.** A page filed in a group that does not match its\n subject. Report it; do not move the page unless asked.\n\nA related page tells you what to check, not what is true. When two pages\ndisagree, the source decides, as described in the section above.\n\nKeep edits to related pages small: a cross-link, a corrected fact, or a short\nentry that points at the owner page. Anything larger is a restructure, so ask\nfirst.\n\n### Never hand-edit generated files\n\nThese are written by a generator. Editing them looks like it works, then a\nscheduled run reverts it, and for the changelogs the edit has already gone out\nover RSS:\n\n| File | Generated by |\n|------|--------------|\n| `src/langsmith/changelog.mdx` and `src/snippets/langsmith/fleet-changelog.mdx` | the `changelog-weekly.yml` workflow (`scripts/changelog_pipeline.py weekly`), from merged langchainplus PRs |\n| `src/langsmith/self-hosted-changelog.mdx` | the helm changelog bot |\n| `src/langsmith/langsmith-platform-openapi.json` | `.github/workflows/refresh-langsmith-openapi.yml` |\n| `src/langsmith/agent-server-openapi.json` | PRs from the `langgraph-api` repository |\n| `src/snippets/deepagents-eval-category-matrix.mdx` | `scripts/refresh_deepagents_category_matrix.py` |\n| `src/snippets/langsmith/mda-oauth-catalog.mdx` | `scripts/refresh_mda_oauth_catalog.py` |\n| `build/` | `make build` |\n\nWhen one of these carries the problem you were asked to fix, fix the generator\nor the upstream source and say so. Do not edit the output.\n\n### When an instruction reverses an earlier one\n\nReviewers change their minds, and on a long thread they will ask for a format\nthey previously rejected. Converting a table to a list and then back wastes a\nround and loses the reasoning both times.\n\nWhen an instruction contradicts one you already applied, say so before applying\nit: name the earlier instruction, the change you made for it, and ask which to\nkeep. Two reversals on the same element mean the requirement is unclear, not\nthat the format is wrong.\n\n## Step 4. Verify before handing off\n\n```bash\nmake lint_prose FILES=\"\"\n```\n\nRun `make broken-links-with-anchors` as well when links, page names, or navigation entries\nchanged. For a prose review against the style guide, use the `docs-review`\nskill.\n\n## Step 5. Report\n\nSay which branch the edits are on and whether it is the PR's own branch. Name\nthe related pages you changed, and the ones you read and left alone. If\nanything could not be verified, list it. Do not push or force-push unless the\nuser asks. When the user asks you to push, the merge-state check and the check\nwatching in `open-docs-pr` apply here too. When the edits have no PR to land\non, open one with `open-docs-pr`.\n\n\n---\nname: docs-restructure\ndescription: Restructure documentation that spans several pages. Covers splitting a page that has grown too long, moving sections between pages, retiring a page, and fixing a topic documented in two places at once. Use when asked to streamline, simplify, consolidate, or reorganize docs, or when a page review keeps producing edits without the page getting shorter.\n---\n\n# Restructure docs across pages\n\nThe failure this skill prevents: an agent asked to \"streamline this page\" reorders\nits sections, collapses them into accordions, retitles them, and tabulates them,\nthirty times over, while the page gets longer. The page was never the problem.\nThree of its sections already existed on sibling pages.\n\nSingle-page skills cannot see that. `add-docs-page` owns one page's lifecycle and\n`docs-edit` owns one page's diff. This skill owns the question they cannot ask:\n**is this content on the right page at all?**\n\n`AGENTS.md` holds the navigation map, the style guide, and the frontmatter rules.\nThis skill covers the procedure around them and does not repeat them.\n\n## Step 1. Establish the page family\n\nA page almost never lives alone. Find its siblings before reading it closely:\n\n```bash\nls src/langsmith/llm-gateway*.mdx # a flat-file family\nls src/oss/deepagents/ # a directory family\ngrep -n '\"langsmith/llm-gateway' src/docs.json # what the nav groups together\n```\n\nThe nav grouping is the better signal when the two disagree: pages a reader\nmoves between are the pages whose content can be confused.\n\nThen list every heading in the family, so you are working from the whole shape\nrather than one file:\n\n```bash\ngrep -n '^## ' src/langsmith/llm-gateway*.mdx\n```\n\n## Step 2. Build a duplication map before writing anything\n\nThis is the step that does the work. For each H2 in the page you were asked to\nfix, search the rest of the family for the same content:\n\n```bash\ngrep -rn 'LANGSMITH_GATEWAY' src/langsmith/ --include=*.mdx\ngrep -rn 'Use a regional gateway' src/ --include=*.mdx\n```\n\nSearch for the distinctive noun, env var, or endpoint in the section, not for\nits heading. Duplicated content is usually retitled, which is why heading\nsearches miss it.\n\nRecord for each section: **does this topic already live somewhere else, and\nwhere?** Two copies that have drifted apart are the strongest finding available.\nIt means no page owns the topic, so both copies are edited independently and\nreaders get contradictions. In one real case the quickstart claimed TypeScript\nsupport for three providers while the sibling page said \"Python only.\"\n\nReport the map before editing anything. \"Three of these six sections duplicate\n`llm-gateway-api-formats`\" is the finding. The restructure is downstream of it.\n\n## Step 3. Assign one home per topic\n\nFor each topic in the map, pick the single page that should own it:\n\n- **Prefer a page that already exists.** A new page is warranted when the topic\n has no home and does not fit an existing one, not when it merely needs\n somewhere to go.\n- **Prefer the page a reader would search for**, not the page the content\n happens to sit on.\n- **Keep the most-linked URL.** Check before choosing, because inbound links\n decide which file survives a merge of two pages:\n\n ```bash\n grep -rn '(/langsmith/llm-gateway)' src/ --include=*.mdx | wc -l\n ```\n\n Folding content *into* the well-linked page and retiring the other one is\n usually cheaper than the reverse.\n\n## Step 4. Cut, do not relocate\n\nA section that duplicates a sibling gets **deleted** and replaced with one\nsentence pointing at the owner. It does not get moved, collapsed into an\naccordion, or shortened in place. An accordion still costs the reader the\ndecision of whether to open it.\n\nContent that has no home yet moves. Content that has one is already written.\n\nWhen you delete a section whose facts differ from the sibling's, the difference\nis a bug in one of them. Resolve it against the source before deleting, or you\nsilently pick a winner. See `docs-edit` for the verification procedure.\n\n## Step 5. Mechanics\n\nRetiring, renaming, or creating a page means navigation entries, redirects, and\ninbound links. `add-docs-page` covers all of it, including the anchor-stability\nand snippet traps. Follow it rather than improvising here.\n\nTwo additional things a restructure breaks that a single-page edit does not:\n\n- **Section anchors other pages link to.** Moving a section moves its anchor.\n Grep for `#the-anchor` across `src/` before the move and repoint every hit. A\n `` or `` can carry an explicit `id` to preserve a landing\n spot that is no longer a heading.\n- **Cross-page pointers that now point at the wrong page.** After moving a\n topic, the sibling pages that used to reference its old location need\n repointing, not just the page you edited.\n\n## Step 6. Verify\n\n```bash\nmake lint_prose FILES=\"\"\nmake build\nmake broken-links-with-anchors\npython3 scripts/check_removed_pages_redirects.py --base-ref origin/main src/docs.json\n```\n\nRead `broken-links-with-anchors` by skipping to the `⎿` lines; those are the\nonly real failures. Compare the count against the same command on `origin/main`\nso a pre-existing baseline is not read as a regression.\n\nThen review the prose with the `docs-review` skill, scoped to the files this\npass changed.\n\n## Step 7. Report what moved\n\nState, per page, what was **deleted**, what **moved**, and what was **added**,\nwith before and after line counts. A restructure that cannot show a page getting\nshorter has not restructured anything, and the line counts are what show the\nreviewer whether it did.\n\nName what you deleted rather than only what you wrote. A reviewer who asked for\na shorter page needs to see the cuts to agree with them.\n\n## Scope\n\nStay inside the page family named in the request. A restructure surfaces\nadjacent problems: stale model IDs, legacy version numbers, and the same\nduplication one directory over. Report them, and **ask before widening the\nsweep.** Fixing sixteen instances across a page family is a reasonable follow-on\ninside one pull request. Fixing six hundred across the corpus is a separate pull\nrequest and probably a tracked issue, because some instances are deliberate and\nsome live in generated files.\n\n## Checklist\n\n- [ ] Page family established from `src/docs.json`, not guessed from filenames.\n- [ ] Duplication map built and reported before any edit.\n- [ ] One owner chosen per topic; most-linked URL identified before merging pages.\n- [ ] Duplicated sections deleted and replaced with a pointer, not relocated.\n- [ ] Conflicting facts between copies resolved against source, not by picking one.\n- [ ] Redirects, nav entries, inbound links, and section anchors all updated.\n- [ ] Verification commands run, `⎿` count compared against `origin/main`.\n- [ ] Report gives per-page before and after line counts.\n- [ ] Anything outside the page family reported, not swept, unless asked.\n\n\n---\nname: docs-review\ndescription: Review changed docs prose against Vale and the AGENTS.md style guide, reporting findings with the rule each one breaks. Use after authoring or editing a page and before committing, or to review a PR, a branch, or the current diff.\nargument-hint: \"[PR number or URL | branch | nothing for uncommitted or current-branch changes]\"\nallowed-tools: Bash(git:*), Bash(gh pr:*), Bash(gh api:*), Bash(make lint_prose:*), Read, Grep, Glob\nlicense: MIT\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# Review docs prose\n\nReview documentation prose that changed in `$ARGUMENTS`, or in the working tree\nand current branch if that is empty.\n\nTwo rules govern this whole skill:\n\n- **Review the diff, not the page.** Prose that was already there is not in\n scope, however much you would have written it differently.\n- **Skip rules that do not clearly apply.** A short report of real findings is\n the goal. Do not stretch a rule to reach a finding, and do not restructure\n prose that is already fine.\n\n## Step 1. Resolve the target\n\nRun `git fetch origin` first so `main` is current. Resolve in this order:\n\n1. **A number or GitHub PR URL** means a PR. Get the branch with\n `gh pr view --json headRefName`.\n2. **A branch name** is used directly.\n3. **Empty, with uncommitted changes present** means the working tree. Take the\n files from `git status --porcelain` plus\n `git diff --name-only --diff-filter=d origin/main...HEAD`. No checkout, no\n worktree: the files are already in front of you. This is the mode that runs\n after an authoring skill.\n4. **Empty, with a clean tree** means the current `HEAD` against `main`:\n `git diff --name-only --diff-filter=d origin/main...HEAD`.\n\nNarrow to `src/**/*.mdx` and `src/**/*.md`. If nothing changed, say so and stop.\nNever review anything under `build/`.\n\n**For modes 1 and 2, check out the target before inspecting anything.** Your\nworking tree is almost certainly on a different branch, and linting it silently\nreports on the wrong content.\n\nFor a PR, check the branch out in the main working tree so any edit that follows\nlands on the open branch:\n\n```bash\ngit stash list # confirm nothing is about to be lost\ngit status --porcelain # must be clean; stop and ask if it is not\ngit fetch origin \ngit checkout # tracks origin/\n```\n\nUse `git checkout `, not `git checkout -b` or a `--no-track` branch. A\nnew branch is only correct when the review is of `main`, or when the user asks\nfor a separate branch of their own edits. Confirm the checkout by grepping for a\nstring the diff added.\n\nFor a review with no edits to follow, a detached worktree is also fine:\n\n```bash\ngit worktree add --detach /review-wt origin/\n```\n\nDo all reading and linting inside it, and `git worktree remove --force` it when\nthe review is done.\n\nState the target, the resolved SHA or \"working tree\", and the file count before\ngoing further.\n\n## Step 2. Run Vale\n\nRun `make lint_prose FILES=\"\"`, in the main checkout or a worktree alike.\nThe target installs the Vale version pinned in `.mise.toml` into `.bin/vale` when\nit is missing, so a fresh worktree needs no setup beyond network access.\n\nVale is deterministic and CI blocks on it, so its output is not a judgment call.\nReport every violation with its file and line. If invoked with `--fix`, correct\nthem; otherwise list them.\n\nLint the merge-base version of each changed file as well, and report the\ndifference rather than the raw count:\n\n```bash\ngit show origin/main: > /base-\nmake lint_prose FILES=\"/base-\"\n```\n\nA file that already failed on `main` carries pre-existing debt the author did\nnot introduce. A file that was clean on `main` and fails now is this diff's CI\nblocker. Say which one it is, because attribution is the difference between a\nfinding the author has to fix and one they can reasonably decline.\n\nReading the diff text is not a substitute for either run. A patch shows added\nlines without their column offsets or their surrounding component, which is\nexactly what these rules turn on.\n\nVale covers terminology, contractions, first person, future tense, Oxford\ncommas, spaced em dashes, navigation-path arrows, and heading case. **Do not\nspend model judgment re-checking what Vale already checks**, with one exception:\nVale does not scan every part of an MDX file, so a clean run is not proof of\ncompliance. It misses content inside JSX components (``, ``, ``,\n``, ``) and inside table cells. A page can pass Vale with four\nspaced em dashes in it.\n\nGrep the mechanical rules yourself over any file whose diff touches those\nplaces:\n\n```bash\ngrep -nE ' — | – ' # spaced em dashes\ngrep -nEi \"\\b(don't|can't|won't|isn't|it's|you'll)\\b\" # contractions\ngrep -nE '\\b(we|our|us|I)\\b|\\bwill [a-z]+\\b' # first person, future tense\ngrep -n '→' # navigation arrows\n```\n\nReport a hit inside a component the same way you would report a Vale error: it\nwould be one if Vale could see it. A `—` used as an empty table-cell marker is\nfine and is not a finding.\n\n## Step 3. Check structure against the style guide\n\nRead the \"Structure conventions\" section of `AGENTS.md` in the repository root,\nthen check the changed hunks against it. For each finding, quote the rule you are\napplying.\n\nLook for these, and nothing else:\n\n- **A new section or page that does not open with a one-sentence definition** of\n what the thing is or does, followed by the benefit, then the task. Skip when\n the section continues directly from the one above it.\n- **Steps introduced without a colon lead-in**, or steps that are not imperative.\n Skip for a list that is not a procedure.\n- **Three or more options, parameters, or permissions written as prose** where\n `- **Term**: Explanation.` would carry them. Skip for fewer than three.\n- **A feature or class linked on repeat mentions**, or a first mention that is\n not linked. Skip when the repeat is far enough down the page to be a genuine\n re-entry.\n- **A permission, plan tier, or preview requirement stated after the steps it\n governs** rather than before them.\n- **A hard constraint hedged** (\"it is generally not possible to change this\")\n where the guide calls for a flat fact (\"Once set, it cannot be changed.\").\n\nPointer phrasing is deliberately absent from that list. Both the long form (\"For\nmore information, see [Page]\") and the short form (\"See [Page]\") are\nestablished. Do not convert between them in either direction.\n\n## Step 4. Check the style guide items Vale cannot see\n\nRead the \"Style guide\" section of `AGENTS.md`. Vale enforces the mechanical half.\nThese are the rules that need reading:\n\n- **Passive voice** where the actor is known. \"Feedback is treated as a signal\"\n hides who treats it. Skip when the actor is genuinely irrelevant or unknown.\n- **Filler and hedging**: \"Note that\", \"Specifically\", \"simply\", \"easily\",\n \"just\", \"very\", \"basically\", \"obviously\". Cut the word, keep the sentence.\n- **A pronoun, \"this\", or \"the above\" whose antecedent the diff removed.**\n Compression is the usual cause: the noun the sentence refers back to sat in a\n clause the edit cut. Name the thing again.\n- **A condition, default, or requirement the diff shortened away.** Compare the\n hunk against its base rather than reading the new text alone. A sentence that\n got shorter by dropping when the behavior applies, or what value it applies\n to, is a regression, and it lints clean. Quote \"Be concise: cut filler words\n and wordy phrases\" and name the fact the cut removed.\n- **Product versus common noun capitalization.** A capitalized feature name that\n appears nowhere else in the file, or that disagrees with the UI label used\n elsewhere on the same page, is the tell. Grep the file for the term's other\n casings before reporting.\n- **Bold in body text** beyond UI labels. Match what the rest of the page does\n rather than an abstract standard.\n- **Repetition inside the diff.** The same list of items enumerated twice in one\n short section, or a sentence restating the one above it.\n- **Link text** that does not describe its destination, and two different labels\n pointing at the same anchor.\n- **Version minimums written with `>=` in prose.** The convention is \"v0.153.4 or\n later\"; `>=` belongs only in package specifiers such as `langsmith>=0.3.13`.\n\nMeasure before reporting a convention violation. If you are about to say a\nheading form or phrasing is wrong, grep the repository for how often it already\nappears. A form used widely is established practice, not a defect, however much\nthe guide seems to prohibit it. Report the count either way.\n\nA diff can also **leave** a convention rather than break a new one. Lowercasing\nthe explanation in `- **Term**: Explanation.`, dropping a trailing period, or\nswapping a colon lead-in for a dash each reads as a harmless copy edit on its\nown. Compare the before and after of that exact form, then count both spellings\nacross `src/`. When the base was following the majority, the change is the\nfinding.\n\nMeasure the same way when the diff **adopts** a convention rather than breaks\none, because a repeated block has three parts and matching two of them still\nlands wrong:\n\n- **Component.** `` or `` or plain prose.\n- **Wording.** Byte-identical to the siblings, or subtly reworded.\n- **Placement.** Before or after the intro paragraph, relative to imports and\n the first heading.\n\nA status callout copied word for word from the one page in thirteen that puts it\nbelow the intro is a finding, and only a placement count surfaces it. Report the\ncount for each of the three.\n\nWhen the same block appears on three or more pages, say so: it belongs in\n`src/snippets/` rather than duplicated. See `add-docs-page`.\n\n## Step 5. Check the mechanics the diff implies\n\nOnly when the diff triggers them:\n\n- A new page: is it in `src/docs.json`, in the right product, tab, and group?\n- A renamed or deleted page: are inbound links and the `docs.json` entry both\n updated?\n- New internal links: root-relative, and free of `/python/` or `/javascript/`?\n- A new code block: does it carry a real language tag, and are imports sorted?\n- A page or heading that changed URL: is there a redirect?\n\nThe `add-docs-page` skill covers all five in detail. Point at it rather than\nrestating the procedure in a finding.\n\n## Step 6. Report\n\nGroup by file. For each finding:\n\n```txt\nsrc/langsmith/example.mdx:42\nRule: \"State requirements and constraints up front\"\nThe admin permission requirement appears after step 3, but governs all of them.\nSuggested: move it above the numbered list.\n```\n\nEnd with a one-line verdict: what blocks merge (Vale violations, missing nav\nentry, broken link) versus what is a suggestion.\n\nIf nothing turns up, say that plainly. \"No findings\" is a valid and useful\nresult, and is more useful than a manufactured one.\n\n## Running after an authoring skill\n\n`add-docs-page` invokes this skill at its verification step, in working-tree\nmode, on the files it just changed. Two constraints keep that useful:\n\n- **Review finished edits, not drafts.** Findings on a half-written section go\n stale as soon as writing resumes, and reporting them trains the reader to\n ignore the report. Run after the edit is complete and before the commit.\n- **Scope to the files the authoring pass touched.** Do not widen to the rest of\n the branch. If other files changed earlier and also want review, say so and\n let the user ask.\n\n\n---\nname: docs-team-voice\ndescription: Write or revise documentation prose so it reads like the rest of this site, in the docs team's shared voice. Covers sentence length, cross-link density, how to state defaults and conditions, naming exact identifiers, and what to cut in a revision pass. Use when drafting or rewriting a page, a section, a concept overview, a how-to, a callout, or landing copy.\n---\n\n# Write in the house voice\n\n`AGENTS.md` holds the rules a linter can check: no contractions, no first\nperson, no future tense, sentence-case headings, Oxford commas, spacing around\ndashes. Vale enforces most of them and `make lint_prose` is the gate, though\nVale does not scan inside JSX components such as `` and ``, so a\nclean run there proves nothing. This skill covers what a linter cannot check:\nrhythm, density, and the shape of a sentence that carries information.\n\nThe targets below are measured from this repository's own pages, not invented.\n\n## Keep sentences short\n\nMedian sentence length on this site is **13 to 15 words**. Roughly one sentence\nin twelve runs past 25 words, one in forty past 30. Treat 25 as the point where\nyou look for a split and 35 as a defect.\n\nOne idea per sentence. When a sentence carries two, split it and let the second\nstand alone.\n\n> The agent definition selects the model and core capabilities of a managed deep\n> agent.\n\n> Set the `compression` field to control how exported Parquet files are\n> compressed. When omitted, LangSmith uses `zstandard`.\n\nThe second example is two sentences where one long one would have hidden the\ndefault inside a subordinate clause.\n\nThe target is a floor as well as a ceiling. Keep the condition, the actor, and\nthe exact value even when they push a sentence long, and split it rather than\ndropping one of them to get under 15 words.\n\n## Link about half the time\n\nClose to half of all prose sentences here carry a link. Cross-linking is not\ndecoration: it is how a reader escapes a page that does not answer the question\nthey arrived with.\n\nLink a term on first mention only. Pointing forward at the end of a section is\nstandard, and **two pointer forms are both established**:\n\n> Refer to [Spend policies](/langsmith/llm-gateway-spend-policies).\n\n> For the full project layout, see [Project\n> structure](/langsmith/managed-deep-agents-project-structure).\n\nNeither is canonical. Different authors favor different ones, so match the form\nthe page already uses and do not mass-convert one into the other.\n\n## State defaults and conditions as bare facts\n\nPut the trigger first, then the behavior. No hedging, no \"please note\".\n\n> When omitted, LangSmith uses `zstandard`.\n\n> Defaults to the last 7 days, newest first.\n\n> Task planning is opt-in.\n\n> Non-zero exits and timeouts from `--startup-cmd` warn but do not abort the\n> session.\n\nConstraints read the same way, as plain statements of fact rather than warnings\nabout them.\n\n## Name the exact identifier\n\nBacktick every field, flag, value, environment variable, and status. Between a\nquarter and a half of prose sentences on this site contain one. Name the actual\nvalue rather than gesturing at it: `zstandard`, not \"the appropriate\ncompression\"; `CREATED`, `RUNNING`, `COMPLETED`, not \"the various statuses\".\n\n> If your API key is linked to multiple workspaces, specify the workspace in the\n> header with `\"x-tenant-id\"`.\n\n## Reach for a concrete example early\n\n\"For example\" appears in roughly one sentence in thirty, almost always followed\nby a real value rather than a shape.\n\n> For example, in SCIM, the resolved `sub` claim and SCIM `externalId` must\n> match in order for login to succeed.\n\nIf you cannot supply a real example, say less rather than inventing one. Never\nfabricate a field name, a response body, or a policy detail to fill a slot.\n\n## Address the reader, and prefer the active voice\n\nSecond person carries a quarter to a half of sentences, most heavily in\nprocedures and UI steps. Passive voice appears in only about one sentence in\neight, and usually where the actor genuinely does not matter.\n\n> When viewing a trace that was generated by a run in LangSmith, you can access\n> the associated server logs directly from the Details view.\n\nUse the product name as the subject when the reader is not the actor: \"LangSmith\nuses `zstandard`\", not \"we use `zstandard`\".\n\n## Revision pass\n\nRead the draft once looking only for these:\n\n- **Sentences over 25 words.** Split, or cut a clause.\n- **Hedges and filler.** \"simply\", \"just\", \"very\", \"basically\", \"note that\",\n \"be sure to\", \"in order to\", \"has the ability to\". These are near-absent from\n this site's prose, well under one percent of sentences. Delete or replace.\n- **A spaced em dash.** `word — word` fails `LangChain.DashesSpaces` and blocks\n CI. Prefer a comma, a colon, or two sentences, and reach for `word—word` only\n when nothing else reads. A bold label opening a paragraph takes a colon:\n `**Tier assignment**:`, measured at 177 uses in `src/` against 1 for the dash.\n- **A vague identifier** where the exact one belongs.\n- **A cut that took a fact with it.** A tightened sentence that lost its\n condition, its actor, or its exact value reads cleanly and says something\n else. Restore the fact and split the sentence.\n- **A first mention with no link**, and repeat mentions that are linked again.\n- **A claim you did not verify.** Check it against the product source with the\n `verify-against-source` skill, or cut it. Another docs page is not a source.\n Name every claim you could not confirm in the PR body.\n- **A fact that disagrees with a related page.** Grep `src/` for the feature and\n read the pages that cover it from another angle, such as a CLI reference or a\n permissions table.

Decides which of the five pages owns the topic, what belongs in the repo instead of Notion, and how to edit safely through the Notion MCP server. Invoke it whenever work adds or changes a script under scripts/, a GitHub Actions workflow, a Makefile target, a PR check, a scheduled job, an agent, a skill, or an MCP server, and invoke it before handing off that pull request. Shipping tooling is itself the trigger, so do not wait to be asked to document it and do not wait for the PR to merge.\nlicense: MIT\nmetadata:\n author: langchain\n version: \"1.0\"\n---\n\n# Document tooling in Notion\n\nThe docs team's internal tooling documentation is five Notion pages under Docs\nTeam. This skill routes a change to the one page that owns it, then edits that\npage without tripping the known Notion failure modes.\n\nRequires the Notion MCP server (`notion-fetch`, `notion-update-page`).\n\n## Rule one: one home per topic\n\nEvery topic lives on exactly one page. Duplicates drift, and drift is worse than\na long page. Before writing anything, search the other four pages for the topic.\nIf it already appears somewhere, update it there instead of adding a second\ncopy.\n\n## Step 1. Route the topic\n\n| Page | ID | Owns |\n|------|----|------|\n| [Docs tooling and agents](https://app.notion.com/p/3ca808527b178153839bff0f2831914c) | `3ca808527b178153839bff0f2831914c` | Parent directory. Page table, \"Owned elsewhere\" list, quick-answers FAQ. |\n| [Docs tech stack](https://app.notion.com/p/30c808527b178073876af57f7d87d8ca) | `30c808527b178073876af57f7d87d8ca` | The production site only: fencing, `src` versus `build`, build pipeline, navigation, integration docs. |\n| [Local setup and quality gates](https://app.notion.com/p/3c8808527b1781dcbaf5d04834a843bf) | `3c8808527b1781dcbaf5d04834a843bf` | mise and prek setup, the `docs` and `mint` CLIs, Vale, git hooks, broken-link triage, the CI matrix, preview deployments, publishing. |\n| [Docs automation and agents](https://app.notion.com/p/3c8808527b17815b81cbf92896b5c3ee) | `3c8808527b17815b81cbf92896b5c3ee` | Scheduled workflows and their cron times, the changelog agents, the #ask-docs intake agent, tracked skills, agent-instruction files, MCP servers. |\n| [Reference docs](https://app.notion.com/p/3c9808527b1781858ebbe92914b02970) | `3c9808527b1781858ebbe92914b02970` | The three LangSmith OpenAPI sources, reference.langchain.com, the `@[ClassName]` link map. |\n\nMost new tooling lands on **Docs automation and agents** (a workflow, script,\nagent, skill, or MCP server) or **Local setup and quality gates** (anything a\ncontributor runs on their own machine or that gates a PR).\n\nThe changelog **system** is not owned by these pages. [LangSmith release\nnotes](https://app.notion.com/p/31b808527b178026943ac2b1ae244021) owns fragments,\nthe fragment schema, and both pipelines. Link to it; do not re-explain it. These\npages keep only the runbook: deployment IDs, HTTP routes, required environment\nvariables, and recovery paths.\n\n## Step 2. Check whether it belongs in Notion at all\n\nDo not write a Notion page for something the repo already documents where people\nfind it. Deliberately excluded: `IDE_SETUP.md`, `.github/brand-guidelines.md`,\n`.github/pull_request_template.md`, `.github/CONTRIBUTING.md`, the issue\ntemplates, and the navigation map, which lives only in `AGENTS.md` because the Notion copy went stale once already.\n\nSkills are the same: a skill is its own authoritative reference. Name it on the\nNotion page, say what it covers and the one or two facts a reader needs in order\nto decide whether to open it, and stop there.\n\nUntracked tooling is not team infrastructure. Anything under a gitignored path\nis personal tooling and does not go on these pages.\n\n## Step 3. Write it\n\nFollow the `docs-team-voice` skill. Do not restate its rules here. The three that\nget missed most often on Notion pages: no first person, no spaced em dashes, and\ndefinition lists written as `- **Term**: Explanation.` with the colon outside the\nbold and a period at the end.\n\nOpen a section with a one-sentence statement of what the thing is, then what it\nenables, then the procedure. Close a substantial page with `## See also`.\n\n## Step 4. Edit safely\n\nFetch the page with `notion-fetch` before every edit. Then use\n`notion-update-page` with `command: \"update_content\"` and narrow\n`content_updates` pairs rather than rewriting the page.\n\nFive failure modes, each of which has already cost a debugging cycle:\n\n- **`old_str` must match the stored indentation exactly.** Tables are stored\n with no leading tabs; callouts do use tabs. A mismatch fails with an\n indentation hint.\n- **Never use `replace_content` on a page holding an uploaded image.** The\n fetched image URL is a short-lived signed S3 link, and rewriting the page body\n can break the image.\n- **A timed-out or async update may already have applied.** Updates default to\n `allow_async: true`. Fetch the page and verify before retrying anything that\n appeared to fail, otherwise the retry duplicates the block.\n- **Bold that contains inline code mid-sentence renders as stray asterisks.**\n Bold wrapping code entirely is fine. Reword so the two do not collide.\n- **In-page anchor links do not resolve.** Notion addresses blocks by ID, not by\n heading slug. Reference sections by name in prose.\n\n## Step 5. Add a row to the Detailed list\n\nThe parent page embeds a **Detailed list** database\n(`collection://3ce80852-7b17-8004-8735-000bc758a8cd`) holding one row per piece\nof tooling. Prose on a page is where someone reads about a thing; this database\nis where they find that it exists at all. It is easy to miss, because the parent\npage renders it as a single inline block.\n\nEvery new workflow, script, skill, agent, MCP server, or git hook gets a row.\nThe schema is Title, Description, Docs page (the URL of the page that explains\nit), Source (the repo paths it lives at), and Type, a select over `GH Actions\n(scheduled)`, `GH Actions (PR/CI)`, `Fleet agent`, `Deep agent`, `External bot`,\n`Skill`, `MCP server`, `Manual script`, and `Git hook`.\n\nQuery it with `notion-query-data-sources` before adding, so a rename becomes an\nupdate rather than a duplicate row. Renaming or moving a file means updating\n`Source` here too, not only in the prose: four rows still pointed at a skills\ndirectory that had been renamed months earlier, and every one of them read as\nplausible.\n\n## Step 6. Close the loop\n\nUpdate the parent page's page table when a page's scope changes, and repoint any\n`## See also` entry that is now wrong. Report which page was edited and what was\ndeliberately left out, so the routing decision is reviewable.\n\n\n---\nname: open-docs-pr\ndescription: Open a pull request for finished docs changes. Covers cutting the branch from the latest origin/main, the lint and link gates, the commit, writing the PR description in the repo's short format with the AI disclosure line, pushing safely, and watching the PR checks until they pass. Use when asked to open, create, put up, or submit a docs PR, or after add-docs-page or docs-edit finishes an edit that has no PR yet.\n---\n\n# Open a docs pull request\n\nThis skill starts when the edit is finished and ends when the PR is open and\nits checks are green. Editing a PR that already exists is `docs-edit`, not this\nskill: pushing a second PR against a teammate's work is the failure that skill\nprevents.\n\nThe rules every task follows live in `AGENTS.md`. This skill is the order to\napply them in.\n\n## Step 1. Branch from the latest main\n\nNever commit to `main`. Cut a new branch from a freshly fetched `origin/main`,\nnot from a local `main` that may be days old:\n\n```bash\ngit fetch origin main\ngit switch -c / --no-track origin/main\n```\n\n`--no-track` stops the branch from tracking `origin/main`, so a bare push\ncannot land on `main`.\n\nThe main checkout may be shared with other agent sessions that switch branches\nunder you. Prefer a worktree inside the checkout:\n\n```bash\ngit worktree add -b / --no-track .claude/worktrees/ origin/main\n```\n\nA new worktree's `.mise.toml` is untrusted, so the first commit fails at the\nVale hook with `Config files in /.mise.toml are not trusted`. Run\n`mise trust` once in the worktree. The `docs-edit` skill covers the permanent\nfix. Run `make skills` in the worktree too if you use Claude Code.\n\n## Step 2. Run the gates\n\nRun each gate that applies to the change before committing. CI runs the same\nones, so a skipped gate becomes a red check later.\n\n- **Prose review**: Run the `docs-review` skill on the changed pages. It covers\n the style-guide rules Vale cannot see. Skip it for a change with no prose.\n- **Vale**: `make lint_prose FILES=\"\"`. Fix every error.\n- **Links**: `make broken-links-with-anchors` when links, page names, anchors,\n or `src/docs.json` changed. Read only the indented `⎿` lines.\n- **Code samples**: `make test-code-samples FILES=\"\"` when a\n file under `src/code-samples/` changed.\n- **Pipeline**: `make test` and `make lint` when `pipeline/`, `scripts/`, or\n `tests/` changed.\n\nNote which gates you ran. The PR checklist asks for them.\n\n## Step 3. Commit\n\nStage only the files the change touched, then check that nothing secret is\nstaged:\n\n```bash\ngit diff --cached --name-only\n```\n\nWrite the subject line in the form recent merged PRs use: `docs: ...` for\ncontent, `docs(): ...` when one product is involved, and `chore: ...`\nfor tooling. The body explains why, not what.\n\nDo not add a `Co-Authored-By` trailer for an AI agent. A ruleset on `main`\nrejects the Claude trailer at merge time, and squash merges carry branch commit\ntrailers into `main`.\n\n## Step 4. Write the PR description\n\nUse the sections in `.github/pull_request_template.md`: **Why**, **Changes**,\n**Review notes**, **Related**, and the checklist. Fill each one in, and delete\nany section that would be empty rather than leaving placeholder comments.\n\n- **Why**: The problem the change solves, in two or three sentences.\n- **Changes**: One bullet per meaningful change, naming the file or page.\n- **Review notes**: Where to look hardest, decisions the reviewer may disagree\n with, and every claim you could not verify against source. A preview link\n goes here once the preview deploys.\n- **Related**: Issues, PRs, Linear tickets, and Slack threads. Write\n `Closes [DOC-N]()` to let `sync-linear-issue-from-pr.yml` move\n the Linear issue with the PR.\n- **Checklist**: Tick only what you actually did in Step 2. Leave the rest\n unticked rather than claiming it.\n\nEnd with one plain sentence that discloses AI involvement, for example\n`Prepared with Claude Code.` Do not add the `🤖 Generated with [Claude Code](...)`\nbadge or any similar badge. The `check-pr-ai-attribution` check fails a PR\nwhose description carries one, because the squash merge would copy it into the\ncommit on `main`.\n\nWrite the description to a file and pass it with `--body-file`. A shell\nheredoc inside `--body \"$(...)\"` breaks on apostrophes in some shells.\n\n## Step 5. Push and open the PR\n\nConfirm the remote is a `langchain-ai` repository, then push with an explicit\nremote and branch. Never run a bare `git push`.\n\n```bash\ngit remote get-url origin # must be github.com/langchain-ai/docs\ngit push -u origin \ngh pr create --base main --head --title \"\" --body-file \n```\n\nOpen it as a draft (`--draft`) if it is not ready for review.\n`pr-welcome-comment.yml` requests reviewers from `.github/OWNERS` when the PR\nleaves draft, so do not request reviewers by hand unless asked.\n\nIf you later push more commits, first check that the PR has not merged. A push\nto a merged PR's branch lands nowhere:\n\n```bash\ngh pr view --json state,mergedAt\n```\n\n## Step 6. Watch the checks\n\n```bash\ngh pr checks --watch\n```\n\nFor a failure, read the log with `gh run view --log-failed`, fix the\ncause on the same branch, and push again. Editing the PR description reruns the\ndescription checks without a new commit.\n\nFor same-repo PRs, `create-preview-branch.yml` comments a preview URL. Forks do\nnot get one.\n\n## Step 7. Record tooling changes\n\nWhen the PR adds or changes a script, workflow, Makefile target, check,\nscheduled job, or skill, invoke `docs-tooling-notion` before handing off.\n\n## Report\n\nGive the PR URL, the branch, the gates you ran and their results, the state of\nthe checks, and anything you could not verify.\n\n\n# Skills Skill\n\nPath: `.agents/skills/README.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/.agents/skills/README.md)\n\n\n---\nname: submit-integration\ndescription: >-\n Create a LangChain docs integration listing from a structured GitHub issue\n submission (issue form fields as JSON).

Do **not** ask clarifying questions and do **not** wait for author input.\n\n- **Do your best** with the form fields, registry metadata, and package README.\n- Prefer the same defaults used when converting integration PRs: partner `docs_url` when it works, otherwise the issue URL / public GitHub README / registry page; external listing under 50K; omit capability flags you cannot verify; infer class/display naming from the package when the form name is clearly a product name.\n- Maintainers review the opened PR. Small judgment calls belong in the PR diff, not in an issue Q&A thread.\n- **Only** emit `integration-submission-error.md` for hard blockers where no reasonable listing is possible (for example, package missing from the registry, or language/package fields that cannot map to any component). Soft uncertainty is not a blocker.\n\n## Policy\n\n| Case | Action |\n|------|--------|\n| **≥50K monthly downloads** (PyPI or npm) **or** explicit maintainer feature override in the issue | Hosted MDX from the matching `TEMPLATE.mdx`. Correct `integration:` frontmatter. Do **not** set `featured: true` unless a maintainer asked. Remove any duplicate external YAML row for the same package. |\n| **Under 50K**, not featured | **External listing only.** No new hosted MDX. |\n\n## External listing checklist\n\n1. Measure downloads (do not invent counts):\n\n ```bash\n curl -s \"https://pypistats.org/api/packages//overall?mirrors=false\"\n curl -s \"https://api.npmjs.org/downloads/point/last-month/\"\n ```\n\n2. Add YAML under the correct language + component in `scripts/data/integration_external_docs.yaml`:\n\n ```yaml\n - name: ClassOrDisplayName\n pypi: langchain-example # or npm: \"@org/pkg\" under javascript:\n docs_url: https://partner.example/docs\n ```\n\n Prefer the issue `docs_url` when it is an http(s) URL. Verify it returns a successful response when practical.\n\n3. Add a downloads-table row in the matching `src/snippets/oss/*-*-downloads.mdx` with a real `data-sort-value` (not `N/A` when a count is known). Match existing badge markup. For vectorstores/chat, map capability notes to the same ✅/❌ spans neighboring rows use.\n\n4. Add an alphabetical `all_providers` card in `src/oss/python/integrations/providers/all_providers.mdx` and/or the JS providers page when applicable. Use `icon=\"link\"` unless a provider icon already exists. For the card body, use issue `provider_description` after trimming whitespace. If that text is longer than **160 characters** (`PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`), rewrite it to one factual sentence of at most 160 characters before writing the card. Keep product and component names; drop marketing, feature lists, and second sentences. Do not invent capabilities that are not in the original text.\n\n5. Append `packages.yml` when there is a public LangChain-related package and public `owner/repo`. Ensure a trailing newline before appending. Omit `path: .`. Quote `js: \"n/a\"` when there is no JS package.\n\n6. Do **not** add `docs.json` nav entries or redirects for never-shipped pages.\n\n7. Do **not** hand-edit generated overview tables.\n\n8. Run `make lint_prose FILES=\"...\"` on changed MDX when prose changed.\n\n## Hosted guide checklist (≥50K)\n\n1. Copy the matching template under `src/oss/{python,javascript}/integrations//TEMPLATE.mdx`.\n2. Fill only with facts from the package README / partner docs / issue fields. Do not fabricate examples.\n3. Update component index / `docs.json` as other hosted pages do.\n4. Remove a duplicate external YAML row for the same package if present.\n\n## CI / handoff rules\n\n- Leave all changes **uncommitted** in the working tree unless the prompt explicitly says to commit.\n- Do **not** `git push` and do **not** open the PR yourself when running under GitHub Actions; the workflow opens the PR.\n- Do **not** comment on the GitHub issue or PR.\n- Write `integration-submission-error.md` only for hard blockers (see Decision style). Prefer completing a best-effort listing over failing.\n\n## Reference\n\n- External YAML: `scripts/data/integration_external_docs.yaml`\n- Downloads snippets: `src/snippets/oss/*-downloads.mdx`\n- Package registry: `packages.yml`\n- Related skill for converting existing PRs: `update-integrations-prs`\n\n\n---\nname: update-integrations-prs\ndescription: >-\n Process open LangChain docs integration PRs against the hosted-guide featuring\n policy (50K monthly downloads or maintainer feature override).

Inspect the current branch\n\n```bash\ngit branch --show-current\ngh pr view --json number,title,url,author,maintainerCanModify,files,body\ngit diff --stat upstream/main...HEAD\n```\n\nFind the LangChain-related package name(s) from `packages.yml`, MDX install snippets, or registry metadata. Ignore unrelated packages with similar names.\n\n### 2. Measure downloads\n\n**PyPI** (last ~30 days, no mirrors):\n\n```bash\ncurl -s \"https://pypistats.org/api/packages//overall?mirrors=false\" \\\n | python3 -c \"import sys,json; d=json.load(sys.stdin); data=d.get('data',[]); last30=data[-30:] if len(data)>=30 else data; print(sum(x.get('downloads',0) for x in last30))\"\ncurl -s \"https://pypistats.org/api/packages//recent\"\n```\n\n**npm** (last month):\n\n```bash\ncurl -s \"https://api.npmjs.org/downloads/point/last-month/\"\n```\n\nReport the number to the user before converting when they asked for downloads only.\n\n### 3. Rebase\n\n```bash\ngit fetch upstream main\ngit rebase upstream/main\n```\n\n- Keep contributor commits; put the conversion in a **new** commit after rebase.\n- On heavy merge history, cherry-pick content commits onto `upstream/main`, then convert.\n- Drop obsolete Card grids that main replaced with `IntegrationDownloads`.\n- Drop redirects for pages that were never on `main`.\n- Drop unrelated `packages.yml` download-count churn from bot commits.\n\n### 4a. External conversion (under 50K)\n\n1. **Delete** hosted MDX (component page and provider page if present).\n2. **Add YAML** under the correct language + component in `scripts/data/integration_external_docs.yaml`:\n\n ```yaml\n - name: ClassOrDisplayName\n pypi: langchain-example # or npm: \"@org/pkg\" under javascript:\n docs_url: https://partner.example/docs\n ```\n\n Prefer partner docs, then public GitHub/GitLab README, then PyPI/npm.\n3. **Downloads snippet** (sort by `data-sort-value`): add a row to the matching `src/snippets/oss/*-*-downloads.mdx` (for example `python-sandboxes-downloads.mdx`). Match existing badge markup.\n4. **`all_providers`**: card with external `href` (alphabetical). Use `icon=\"link\"` or an existing provider icon. Card body max **160 characters**. If a draft description is longer, shorten it to one factual sentence ≤160 characters; do not invent claims. Limit: `PROVIDER_CARD_DESCRIPTION_MAX_LEN` in `scripts/provider_card_limits.py`.\n5. **`packages.yml`**: append only for a public LangChain-related package. Ensure a trailing newline before appending. Omit `path: .`. Skip if the source repo is private or not a normal public VCS listing.\n6. **Nav / redirects**: remove `docs.json` entries and redirects for deleted never-on-main pages. Do not add redirects for pages that never shipped.\n7. **Deep Agents / indexes**: if the PR added provider cards that main no longer uses, prefer downloads tables and index grids; keep brief mentions only when main already lists providers that way.\n\nAlign listings with **partner docs**, not stale PR page counts.\n\n### 4b. Hosted / featured path (≥50K or override)\n\n1. Keep (or fix) hosted MDX; test code examples when touching them.\n2. Frontmatter: follow templates under `src/oss/*/integrations/**/TEMPLATE.mdx`. Do not set `featured: true` unless a maintainer asked.\n3. Prefer `langchain` imports over `langchain_core` when editing kept pages.\n4. For featuring: set `highlight: true` in `packages.yml` only when asked; regenerate overview with the partner package table tool, do not hand-edit `overview.mdx`.\n5. Update `src/docs.json` if adding a page that should stay.\n\n### 5. Commit and handoff\n\n- Conversion commit message focuses on why (threshold / external listing / feature).\n- Show `git diff --stat upstream/main...HEAD` and downloads in the summary.\n- Note `maintainerCanModify` for push later.\n- **Do not push** unless the user asks. Use force-with-lease after rebase when pushing to the PR head.\n- If `maintainerCanModify: false`, say so and ask whether to open a replacement PR.\n\n## Hard rules\n\n- Ask for clarification rather than assuming package identity or feature overrides.\n- Never fabricate download counts, docs URLs, or package names.\n- Never edit `build/`.\n- Never hand-edit generated overview tables.\n- When appending to `packages.yml`, ensure a trailing newline first.\n- Run `make lint_prose FILES=\"...\"` on changed MDX before handoff when prose changed.\n- Follow repo git safety: no bare `git push`; no force to main; no commit unless asked (except when the user said \"go\" / \"next branch\" for this workflow, commit the conversion).\n\n## Common pitfalls\n\n| Pitfall | Fix |\n|---------|-----|\n| Wrong package (similar name on PyPI) | Confirm against install snippets and partner repo |\n| Re-adding Card grids removed on main | Use `IntegrationDownloads` / YAML only |\n| Redirects for never-shipped pages | Delete them |\n| Duplicate table rows | Remove YAML if keeping hosted page |\n| Private source repo | Skip incomplete `packages.yml` entry |\n| JS + Python packages | Add both YAML sections / download rows when both exist |\n\n## Reference\n\n- Eligibility docs: `/oss/contributing/publish-langchain#eligibility-for-hosted-guides`\n- YAML data: `scripts/data/integration_external_docs.yaml`\n- Downloads snippets: `src/snippets/oss/*-downloads.mdx`\n- Package registry: `packages.yml`\n- Policy PR: https://github.com/langchain-ai/docs/pull/4865\n\n\n---\nname: verify-against-source\ndescription: Check that a code sample, API signature, default, or behavior claim in the docs is actually true, by running it or reading the product source. Covers which repository owns each product, how to reach the private ones, running the part of a sample that needs no API key, and what to say about a claim you could not verify. Use when writing or reviewing a page that asserts how LangChain, LangGraph, Deep Agents, or LangSmith behaves, and when a PR describes behavior without citing where it was checked.\n---\n\n# Verify a claim against the source\n\nThe failure this skill prevents: a page states a default, a precedence order, or\na field name that reads plausibly, passes Vale and the link checker, and is\nwrong. Nothing in CI checks whether a sentence about product behavior is true.\nA reviewer who knows the product catches some of it; the rest reaches readers.\n\nPublished docs, a README, and a model's recollection are all secondary sources.\nPrefer evidence you produced in this session.\n\n## Step 1. Pick the strongest evidence available\n\nWork down this list and stop at the first rung you can actually reach. Each rung\nis weaker than the one above it.\n\n- **Run the sample.** `make test-code-samples`, or scope it with\n `FILES=\"src/code-samples/langchain/foo.py\"`. This is the only method that\n proves a sample works end to end. It needs provider API keys in the\n environment, so it often fails locally and runs in CI instead.\n- **Run the half that needs no model.** Most claims are about a library's\n behavior, not the model's. Stand up the real object in a scratch script and\n print what it returns. A local MCP server, an adapter, a parser, or a store\n needs no API key, and the answer it gives is exact rather than inferred.\n- **Read the library source.** `gh api repos/langchain-ai//contents/\n --jq '.content' | base64 -d`, or `gh api \"search/code?q=+repo:langchain-ai/\"`\n to locate the file first. Settles what a type is, what a default is, and which\n branch actually runs.\n- **Check the installed package.** `uv run python -c \"from x import Y\"` confirms\n an import path resolves at the version this repo pins, which source on `main`\n cannot tell you.\n- **Look up the signature.** The `reference-langchain` MCP server exposes\n `search_api` and `get_symbol` over reference.langchain.com. Right for \"what\n are the parameters of X\", not for \"what does X do at runtime\".\n\n## Step 2. Know which repository owns the claim\n\n| Product | Repository | Where to look |\n|---------|------------|---------------|\n| LangChain | [langchain-ai/langchain](https://github.com/langchain-ai/langchain) | `libs/langchain_v1/langchain/` for v1, `libs/core/` for core, `libs/partners/` for provider packages |\n| LangGraph | [langchain-ai/langgraph](https://github.com/langchain-ai/langgraph) | `libs/langgraph/`, `libs/prebuilt/`, `libs/checkpoint*/`, `libs/cli/`, `libs/sdk-py/` and `libs/sdk-js/` |\n| Deep Agents | [langchain-ai/deepagents](https://github.com/langchain-ai/deepagents) | Also the source of the eval matrix the docs publish |\n| LangSmith SDK | [langchain-ai/langsmith-python](https://github.com/langchain-ai/langsmith-python) and [langchain-ai/langsmith-javascript](https://github.com/langchain-ai/langsmith-javascript) | The Python and JavaScript client libraries |\n| LangSmith platform | langchain-ai/langchainplus (private) | `smith-backend/` (Python API), `smith-go/` (Go services), `smith-frontend/` (UI labels and flows), `host-backend/`, `lc_config/` for settings and their defaults |\n| Agent Server | langchain-ai/langgraph-api (private) | Not in the OSS langgraph repo. Also the source of the Agent Server OpenAPI spec PRs |\n| Helm charts | [langchain-ai/helm](https://github.com/langchain-ai/helm) | `charts/langsmith/values.yaml` for defaults, `templates/_helpers.tpl` for the value-to-environment-variable mapping |\n| OpenEvals | [langchain-ai/openevals](https://github.com/langchain-ai/openevals) | Prebuilt evaluators |\n\nTwo traps worth naming:\n\n- **A private repo is still readable through `gh`.** `gh api` works on\n langchainplus and langgraph-api with the usual credentials. GitHub code search\n is unreliable on the larger ones, so fall back to the git trees API and fetch\n a path directly.\n- **langchain-ai/deployments is archived.** Its GitOps content moved into\n langchainplus. A skill, script, or note that still points at it is stale.\n\nA self-hosted LangSmith claim usually spans two repositories: the chart sets a\nvalue, and the backend decides what to do with it. Check both before describing\nprecedence, because the chart alone does not tell you which setting wins.\n\n## Step 3. Verify the claim, not the sentence\n\nRead the code path that produces the behavior, rather than a name that sounds\nlike it. Three failures that recur:\n\n- **A resolution order inferred from a settings table.** Find the query or the\n conditional that picks a value. An `ORDER BY`, a `COALESCE`, or an `or`\n expression is the precedence; a list of configurable fields is not.\n- **A defensive pattern copied from another sample.** Check whether the guarded\n case can occur. If the constructor only builds an object when a field is\n present, a `.get` with a default is documenting a state that never exists.\n- **A version or model identifier from memory.** Fetch it. The repository's own\n internal consensus is evidence about the repository, not about the provider.\n For model IDs specifically, see the Model references section of `AGENTS.md`.\n\n## Step 4. Record what you checked, and what you could not\n\nName the file and symbol in the pull request body, not just the conclusion. A\nreviewer can then disagree with the evidence rather than with an assertion.\n\nState the gaps in the same place. Common ones that no amount of source reading\ncloses:\n\n- **A UI string.** Source gives you a field and a component; only the running\n product gives you the rendered label. Describe the behavior rather than\n quoting a label you have not seen.\n- **The model-dependent half of a sample.** Say that CI has yet to run it.\n- **A beta surface.** `langchain.mcp` and similar namespaces can move under a\n page that was accurate when written.\n\nWriting \"not verified: the visible label of this control\" is a better outcome\nthan a confident sentence a reader discovers is wrong.\n\n## Related\n\n`AGENTS.md` holds the rules that apply to every edit, including never\nfabricating an example and testing code before publishing it. Use\n`docs-code-samples` when the claim belongs in a runnable sample rather than in\nprose, and `docs-review` for the style pass once the facts are settled.\n\n\n---\nname: deepagents-code\ndescription: Analyze Deep Agents Code releases against LangChain Deep Agents Code docs and prepare one-feature documentation updates.\n---\n\n# Deep Agents Code docs release skill\n\nUse this skill when the product is Deep Agents Code (Products and setup → Deep Agents Code). Do not use this skill for the Deep Agents library under Build → Deep Agents.\n\n## Sources of truth\n\n- Releases: GitHub `langchain-ai/deepagents` via `get_eligible_release` / `get_release_notes`\n- Important: that repo publishes several packages. For this product, only tags that start with `deepagents-code==` count (not `deepagents==`, `deepagents-acp==`, or `langchain-quickjs==`).\n- Docs paths in `langchain-ai/docs`:\n - `src/oss/deepagents/code/` only\n - Navigation for Deep Agents Code in `src/docs.json`\n - Docs style authority: root `AGENTS.md` in `langchain-ai/docs` (read via `get_docs_file` before drafting)\n- Changelog page: `src/oss/deepagents/code/changelog.mdx` (points at the upstream code changelog)\n\nDeep Agents Code pages are unversioned (no Python/TypeScript language split). Conditional fences still resolve against the Python branch.\n\n## What usually needs docs\n\nPrioritize user-facing changes:\n\n- New CLI commands, flags, config keys, or slash commands\n- New providers, plugins, hooks, MCP wiring, or credential flows\n- Approval modes, subagents, sandboxes, or remote sandbox behavior\n- Behavior changes that make existing docs wrong\n- New minimum versions that docs should call out\n\nUsually skip docs for:\n\n- Internal refactors with no user-visible change\n- Dependency bumps with no behavior change\n- Pure bug fixes that do not change documented behavior\n- Changes that belong only to the Deep Agents library (`deepagents==...` releases)\n\nWhen unsure, open a small clarifying ticket/PR only if a reader of the current docs would be misled.\n\n## Workflow for one Deep Agents Code release\n\nThe main agent must run **phase 1** through the `release-research` subagent first (diff + source investigation). This skill guides **phase 2** shipping and judgment details the subagent also uses.\n\n1. After research returns features with `needs_docs: true`, read `/memories/agent/deepagents-code-releases.md` and skip any already recorded for that tag.\n2. Call `get_docs_file` on `AGENTS.md` and read it in full. Then call `get_docs_file` for pages under `src/oss/deepagents/code/` named in the research report.\n3. For each remaining feature:\n - Edit surgically from the page `get_docs_file` content, following the docs repo `AGENTS.md`.\n - Prefer updating the owning page over creating a new page. If a new page is required, also plan the `src/docs.json` navigation update under Deep Agents Code.\n - Load the `ship-docs-update` skill and ship that feature alone with the research report's `evidence` as `evidence_json`.\n4. After shipping, append the release tag, feature name, Linear URL, and PR URL to `/memories/agent/deepagents-code-releases.md`.\n5. Keep `/memories/agent/AGENTS.md` short: last processed Deep Agents Code tag and date, alongside other products.\n\n## Memory format\n\nUse cold memory file `/memories/agent/deepagents-code-releases.md`:\n\n```md\n# Deep Agents Code release tracking\n\n## deepagents-code==0.1.84\n- feature: remote sandboxes config\n - linear: https://linear.app/...\n - pr: https://github.com/langchain-ai/docs/pull/...\n```\n\n\n# deepagents\n\nPath: `docs-release-watch/skills/deepagents/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/docs-release-watch/skills/deepagents/SKILL.md)\n\n\n# deepagentsjs\n\nPath: `docs-release-watch/skills/deepagentsjs/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/docs-release-watch/skills/deepagentsjs/SKILL.md)\n\n\n# openwiki\n\nPath: `docs-release-watch/skills/openwiki/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/docs-release-watch/skills/openwiki/SKILL.md)\n\n\n# release-research\n\nPath: `docs-release-watch/skills/release-research/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/docs-release-watch/skills/release-research/SKILL.md)\n\n\n# ship-docs-update\n\nPath: `docs-release-watch/skills/ship-docs-update/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/docs-release-watch/skills/ship-docs-update/SKILL.md)\n\n\n# Mdoutput Skill\n\nPath: `pipeline/tools/notebook/notebook_convert_templates/mdoutput/conf.json`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/pipeline/tools/notebook/notebook_convert_templates/mdoutput/conf.json)\n\n\n# deep-agents\n\nPath: `src/.mintlify/skills/deep-agents/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/.mintlify/skills/deep-agents/SKILL.md)\n\n\n# langchain\n\nPath: `src/.mintlify/skills/langchain/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/.mintlify/skills/langchain/SKILL.md)\n\n\n# langgraph\n\nPath: `src/.mintlify/skills/langgraph/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/.mintlify/skills/langgraph/SKILL.md)\n\n\n# langsmith\n\nPath: `src/.mintlify/skills/langsmith/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/.mintlify/skills/langsmith/SKILL.md)\n\n\n# langgraph-docs\n\nPath: `src/code-samples/deepagents/skills/langgraph-docs/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/code-samples/deepagents/skills/langgraph-docs/SKILL.md)\n\n\n# write-timestamp\n\nPath: `src/code-samples/deepagents/skills/write-timestamp/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/code-samples/deepagents/skills/write-timestamp/SKILL.md)\n\n\n# pandas-patterns\n\nPath: `src/code-samples/langchain/skills/pandas-patterns/SKILL.md`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/src/code-samples/langchain/skills/pandas-patterns/SKILL.md)\n\n\n# Cursor Rule: docs-style\n\nPath: `.cursor/rules/docs-style.mdc`\n\n[View Raw Content on GitHub](https://raw.githubusercontent.com/langchain-ai/docs/HEAD/.cursor/rules/docs-style.mdc)\n\n\n"}
