Use for isolated Herdr runtime, pane, terminal, process, API, persistence, or agent reproductions that should be driven through the CLI/API without touching the default session.\n---\n\n# Herdr throwaway reproduction\n\nUse a disposable named Herdr session when a reproduction needs a real Herdr server, panes, PTYs, agents, or socket API without risking the user's main session.\n\nThe temporary TUI only keeps the disposable session attached and supplies terminal geometry. Drive the reproduction from the parent session through Herdr's CLI/API. Do not manually operate the nested TUI unless the bug specifically requires client input.\n\n## Non-negotiable safety\n\n- Never run the reproduction in the default session.\n- Never stop, restart, delete, or kill the main Herdr server.\n- Never use `pkill`, broad process matching, or guessed PIDs for cleanup.\n- Create a unique session name. Never reuse or delete an unrelated named session.\n- Create a new outer pane and close only that pane during cleanup.\n- Read workspace, tab, pane, terminal, and agent IDs from command output. Never construct them.\n- Use `/var/tmp` for reproduction directories and potentially large artifacts.\n- Do not approve destructive or unnecessary agent actions.\n- Do not spend paid agent tokens without the user's approval. Use the requested low-cost model and the smallest useful prompts.\n\n## Learn the installed interface first\n\nThe installed binary is the authority. CLI syntax may have changed since this skill was written.\n\nConfirm the caller is inside Herdr and inspect the relevant help before doing anything:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\nherdr --version\nherdr --help\nherdr session\nherdr pane\nherdr agent\n```\n\nInspect nested command help before using unfamiliar or potentially mutating commands. Do not run bare `herdr` for discovery because it launches or attaches the TUI.\n\nRecord which Herdr binary and version the reproduction tests. If testing a checkout build, follow the repository's instructions for running that build instead of silently substituting the installed binary.\n\n## Create the outer pane\n\nCreate a sibling shell pane in the current tab without moving focus. Use an available Herdr layout tool when the harness provides one. Otherwise use the installed pane split command after checking its help.\n\nUse `/var/tmp` or a dedicated reproduction directory as the new pane's cwd. Save the returned outer pane ID. This is the only parent-session pane that cleanup may close.\n\n## Start the disposable session\n\nChoose a short unique name such as `repro-<topic>-<timestamp>`.\n\nBefore launching, explicitly allow nesting in the configuration the disposable\nclient will actually load. `HERDR_ENV=1` is inherited from the outer pane, so the\nlaunch is otherwise rejected unless `[experimental].allow_nested` is enabled.\nAn isolated `XDG_CONFIG_HOME` does not inherit this setting from the user's global\nconfig, even when nesting is enabled there.\n\nCreate a test-only config under the reproduction directory using the file-writing\ntool. For a default-config reproduction, its contents can be:\n\n```toml\n[experimental]\nallow_nested = true\n```\n\nIf reproducing with the user's configuration, copy that configuration into the\ntest directory and enable `allow_nested` in its existing `[experimental]` table\n(or add the table if absent). Do not create duplicate tables or keys. Never edit\nthe user's global configuration to permit a reproduction, and do not unset\n`HERDR_ENV` to bypass the nesting check.\n\nPass the absolute test config path as `HERDR_CONFIG_PATH` when launching below.\nUse the same override for config validation and any commands that must load the\ntest config. This override selects a config file; it does not isolate the saved\nmachine catalog or other global state. Use test-only `XDG_CONFIG_HOME` and\n`XDG_STATE_HOME` as well when the reproduction changes saved machines, and retain\nthose overrides on every command addressing that test environment.\n\nRun the named session inside the new outer pane. Clear inherited session selection, socket overrides, and caller IDs so the nested runtime cannot accidentally address the parent session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_SESSION \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_CONFIG_PATH=<absolute-test-config-path> \\\n  herdr --session <session-name>\n```\n\nAdd reproduction-specific environment variables to this launch command when needed. Environment variables that configure the server must be present before the named server starts.\n\nValidate the test config with `herdr config check` using the same config override\nbefore launch. After launch, read the outer pane to catch startup errors such as\n`nested herdr is disabled by default`; do not assume the launch succeeded merely\nbecause `pane run` returned successfully.\n\nDo not continue until the named session's API is ready. Confirm readiness by addressing that session from the parent and listing its panes.\n\n## Address only the disposable session\n\nEvery control command issued from the parent must clear inherited socket overrides and explicitly select the temporary session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_SESSION=<session-name> \\\n  herdr pane list\n```\n\nRepeat this prefix for every command. Do not rely on shell state persisting between tool calls.\n\nRead the disposable root pane ID from `pane list`. Confirm its cwd and foreground process before starting anything in it.\n\nNamed sessions isolate runtime state, sockets, panes, and persistence. They still share global Herdr configuration and agent manifest overrides by default. Check configuration provenance when it could affect the reproduction. Do not modify shared configuration merely to make the test pass.\n\n## Drive the reproduction through the API\n\nUse pane commands for shells and ordinary processes:\n\n- `pane run` to start a command at an available shell prompt.\n- `pane wait-output` to wait for deterministic output.\n- `pane read` to capture terminal contents.\n- `pane send-text` for literal input.\n- `pane send-keys` for supported keys.\n- `pane get`, `pane process-info`, and `pane layout` for runtime state.\n\nUse agent commands only after Herdr recognizes a coding agent:\n\n- `agent start` to launch a supported agent in an existing shell pane.\n- `agent prompt` to submit one prompt atomically.\n- `agent wait` to wait for `working`, `blocked`, `idle`, `done`, or `unknown`.\n- `agent read` to capture the agent terminal.\n- `agent get` and `agent explain` to inspect state and detection.\n- `agent send-keys` for interactive responses.\n\nRun the relevant command group's help first because names and options may change.\n\nPrefer waits over arbitrary sleeps. When timing itself is under test, record timestamps and use bounded polling. Capture state before, during, and after the transition being reproduced.\n\nWhen a needed terminal key is unsupported by the high-level command, send its terminal sequence through the disposable pane only after confirming the target application's expected key. Never send raw control sequences to the parent pane.\n\n## Start agents carefully\n\nBefore launching an agent, inspect its installed `--version` and `--help`. Pass native agent arguments after Herdr's argument separator.\n\nUse the exact model requested or approved by the user. Verify the model from the live agent screen instead of trusting an alias. Prefer low effort, safe mode, and manual permissions for a baseline when the agent supports them. Repeat with the user's real configuration only when the suspected behavior depends on hooks, plugins, or settings.\n\nUse harmless operations for permission-state testing. Reject the pending action after evidence is captured and verify that no artifact was created.\n\n## Collect useful evidence\n\nRecord enough information for another person to repeat the result:\n\n- Herdr binary and version.\n- Named session and launch environment.\n- Target application or agent version and arguments.\n- Exact commands or prompts.\n- Pane and agent state before and after each transition.\n- Relevant `pane read`, `agent read`, `agent explain`, API output, and session logs.\n- Whether global config or a local manifest override was active.\n\nRead the named session directory and socket from `herdr session list` instead of assuming their paths. Keep large evidence under `/var/tmp` unless the user asks to preserve it elsewhere.\n\nDistinguish observed facts from proposed causes. First reproduce stock behavior, then change one variable at a time.\n\n## Cleanup\n\nCleanup is part of the reproduction, including after failure.\n\n1. Reject pending prompts and stop test applications cleanly when practical.\n2. Verify that harmless probe files or other test artifacts do not exist, or remove only artifacts created by this reproduction.\n3. Stop the temporary named session with the installed session command.\n4. Delete that same stopped session.\n5. Confirm it no longer appears as running.\n6. Wait for the outer pane to return to its shell.\n7. Close only the outer pane created by this workflow.\n\nNever delete another named session because it looks stale. Never close the pane running the current agent or any pane not created for the reproduction.\n\n## Report the result\n\nState what reproduced, what did not, and the exact transition that failed. Include cleanup status. Mention shared configuration or manifest overrides that may have influenced the result.\n","skills/herdr/SKILL.md":"---\nname: herdr\ndescription: \"Control Herdr, a terminal multiplexer for coding agents. Use only when the user explicitly mentions Herdr or asks to use Herdr to inspect or control panes, tabs, workspaces, commands, or another agent. Do not use merely because a task could benefit from a background terminal, delegation, or parallel work. Requires HERDR_ENV=1.\"\n---\n\n# Herdr\n\nHerdr organizes terminals into workspaces, tabs, and panes, recognizes coding agents running inside panes, and exposes the current session through the `herdr` CLI.\n\nBefore issuing any control command, verify that this agent is running inside a Herdr-managed pane:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\n```\n\nIf the check fails, say that you are not running inside Herdr and stop. Do not inspect or control the focused Herdr session from outside Herdr.\n\nWhen the check passes, the `herdr` binary in `PATH` talks to the current session. Use it to inspect neighboring work, create terminal layout, start agents and commands, read output, and wait for state changes.\n\n## Learn the current CLI\n\nThe installed binary is the authority for command syntax. Start with:\n\n```bash\nherdr --help\n```\n\nThen print the relevant command group by running the group without a subcommand:\n\n```bash\nherdr agent\nherdr pane\nherdr workspace\nherdr tab\nherdr worktree\nherdr terminal\nherdr notification\nherdr integration\nherdr session\nherdr machine\n```\n\nDo not run bare `herdr` for discovery; it launches or attaches the TUI. Do not probe a mutating nested command by omitting arguments. Commands such as `herdr workspace create` are valid with defaults and will execute.\n\nMost control commands return JSON. Read identifiers and state from those responses instead of predicting them.\n\n## Understand layout, panes, and agents\n\nChoose the primitive that matches the job:\n\n- Workspace, tab, and pane topology organize terminal locations.\n- Pane commands control raw terminals, shells, tests, servers, input, and output.\n- Agent commands control the recognized coding agent currently occupying a pane.\n\nA pane exists whether or not it contains an agent. `agent start` requires an existing available shell pane and never creates, splits, or moves layout. Use pane commands for ordinary processes. Use agent commands when Herdr must validate agent identity or interpret `idle`, `working`, `blocked`, `done`, and `unknown` lifecycle states.\n\nAgent commands accept either a unique live agent name or the pane ID currently hosting that agent. They do not accept terminal IDs or bare agent-kind labels. Names must match `[a-z][a-z0-9_-]{0,31}` and be unique among live agents. A name follows the current pane occupant and is cleared when that agent exits, is released, or is replaced. Suspending an agent with Ctrl+Z and running a non-agent command preserves its identity while the exact process remains alive. This does not preserve the original identity across another recognized agent taking over. A retained identity does not mean the agent is in the foreground; inspect the pane before sending input.\n\n`idle` and `done` normally indicate the agent is ready for input; neither guarantees that an unfamiliar approval dialog was recognized or that a retained agent is in the foreground. The CLI/API uses the server's seen state to distinguish them; explicit focus commands mark the target seen, while reads do not. Each TUI client tracks viewed completions independently, so its Done badge can differ from the CLI or another client's badge. Antigravity and Grok can be idle while background tasks or subagents keep running, so a settled-state wait is not proof those jobs have finished. `blocked` means Herdr recognized an approval or question UI. `unknown` means an agent is present but Herdr cannot classify it confidently; it does not prove completion.\n\n## Use IDs and caller context\n\nPublic IDs are opaque stable handles:\n\n- workspace: `w1`\n- tab: `w1:t1`\n- pane: `w1:p1`\n\nClosed tab and pane IDs are not reused. A pane moved into another workspace receives a new workspace-qualified pane ID. After `pane move`, continue with `.result.move_result.pane.pane_id` or the live agent name. The old value is reported as `.result.move_result.previous_pane_id`; only the moved process's inherited caller context keeps resolving that old ID, so do not use it as a general agent target.\n\nHerdr injects the caller's context into each managed pane:\n\n```bash\nprintf '%s\\n' \"$HERDR_WORKSPACE_ID\" \"$HERDR_TAB_ID\" \"$HERDR_PANE_ID\"\n```\n\nPrefer `--current` when a pane command should target the calling pane. An omitted `pane split` target uses the calling pane when `HERDR_PANE_ID` is available, otherwise the focused pane. Other commands may use the UI-focused pane, which can belong to the user or another client.\n\nDiscover live state with:\n\n```bash\nherdr workspace list\nherdr tab list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr pane current --current\nherdr pane list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr agent list\n```\n\nCreation responses expose the IDs to use next. `workspace create` returns `.result.workspace`, `.result.tab`, and `.result.root_pane`. `tab create` returns `.result.tab` and `.result.root_pane`. `pane split` returns the new pane as `.result.pane`.\n\nIDs and live agent names are scoped to one server. Two saved SSH machines can both have `w1:p1` or an agent named `reviewer`. Selecting a machine in the TUI does not retarget commands running in your pane: without `--machine`, they still use the inherited session and socket context.\n\nTo control a saved SSH machine, use the same global prefix for discovery and every later command:\n\n```bash\nherdr --machine <label-or-id> agent list\nherdr --machine <label-or-id> pane list\nherdr --machine <label-or-id> agent prompt <remote-agent-name> \"Reply with your current status.\" --wait --timeout 120000\n```\n\nThe selector must be an enabled saved profile ID or a unique, case-sensitive label, not an arbitrary SSH hostname. Commands use that profile's remote session without an open TUI. Do not combine `--machine` with `--session` or `--remote`. Discover IDs on that machine; inherited local IDs and `--current` do not identify remote panes.\n\nBoth installations must support machine API forwarding, and the remote server must already be running and API-compatible. Forwarding never installs, starts, or restarts a server and never falls back to Local. Local configuration, session management, installation commands, and interactive attachment are not forwarded. Remote worktree paths must be absolute, `~`, or start with `~/`; plugin link paths must be absolute. A connection failure does not prove a mutation was not applied: inspect remote state before retrying.\n\n`herdr machine list` lists saved connection profiles, not a cross-machine pane inventory; add `--json` for scripts. Only add, remove, enable, or disable profiles when the user asks. Removing a profile disconnects the client but does not stop remote sessions. Interactive `machine add` discovers running remote sessions and may ask the user to pick one; non-interactive setup uses the remote default session unless `--remote-session` is explicitly supplied. Use `herdr machine status [<label-or-id>] --json` to diagnose a failing machine. `herdr machine reconnect` needs the user to complete SSH authentication in their terminal; do not run it for them. Setup asks before stopping an incompatible server and defaults to No; do not approve replacement without the user's consent. Experimental handoff is not part of `machine add`.\n\n## Start and coordinate an agent\n\nDefault to a sibling pane in the current tab and the current working directory. Do not create a workspace, tab, worktree, or different cwd unless the user explicitly requests that topology or location.\n\nHonor a direction requested by the user. Otherwise inspect the caller pane:\n\n```bash\nherdr pane layout --pane \"$HERDR_PANE_ID\"\n```\n\nSplit a wide pane to the right and a narrow or tall pane down. Avoid repeated same-direction splits that create unusably narrow columns or short rows. Keep the user's focus in the calling pane and explicitly preserve the caller's working directory:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nReplace `right` with `down` when appropriate. Read the new pane ID from `.result.pane.pane_id`.\n\nAn available shell pane must be at its interactive prompt, with the shell itself in the foreground and no foreground command, editor, or agent running. Start a supported agent in that pane with a useful unique name:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id>\n```\n\nUse the kind requested by the user. Run `herdr agent` to inspect the installed kind list and options. Pass native agent arguments only after `--`:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id> -- <agent-args...>\n```\n\nA successful `agent start` returns only after Herdr detects the expected agent in the same pane and considers it ready for interactive input. If the agent is blocked during startup, the command returns `agent_not_ready` immediately but keeps the name available for `agent read` and `agent send-keys`. Wait until the agent becomes idle before prompting it. Startup defaults to a 30-second timeout.\n\nSubmit work through the agent surface:\n\n```bash\nherdr agent prompt reviewer \"Review the current diff and report only actionable findings.\" --wait --timeout 120000\n```\n\n`agent prompt` honors the pane's live bracketed-paste mode and sends text followed by encoded Enter as one ordered submission. It reports successful submission only after both have been written; that alone does not prove the agent started a turn. For Codex on Windows, Herdr sends a paste boundary before Enter so submission does not depend on prompt size. It rejects an agent already waiting at an approval or question dialog with `agent_blocked` before sending any input. Inspect the blocked UI and ask the user before answering it. For normal agent work, `--wait` is enough: it waits for the first settled `idle`, `done`, or `blocked` state. Do not repeat those defaults with `--until`.\n\nWith `--wait`, a prompt sent from a non-working state must produce observed `working` or `blocked` activity. After submission, Herdr waits up to five seconds for that activity; unrelated `idle`, `done`, or session changes do not satisfy this gate. It returns `agent_prompt_stalled` if no activity is observed, or `timeout` if the caller's timeout expires first. The caller timeout includes submission time. Without a timeout, the settled-state wait is indefinite after activity is observed. This wait tracks lifecycle state, not an individual turn; if the agent is already working, completion of the active turn may satisfy it.\n\nUse `--until` only for a state-specific workflow, such as waiting for an already-running agent to request input:\n\n```bash\nherdr agent wait reviewer --until blocked --timeout 120000\n```\n\nWithout `--until`, standalone `agent wait` uses the same settled-state defaults as `agent prompt --wait`.\n\nUse logical keys for interactive agent UI controls:\n\n```bash\nherdr agent send-keys reviewer esc\nherdr agent send-keys reviewer ctrl+c\n```\n\nHerdr validates all keys before writing any bytes. Read the result through the resolved agent:\n\n```bash\nherdr agent get reviewer\nherdr agent read reviewer --source recent-unwrapped --lines 120\n```\n\nIf a wait fails or returns `blocked`, inspect `agent get` and `agent read` before deciding what input to send. A timeout or stalled response does not prove the prompt was never delivered; do not blindly submit it again. Use the pane surface only when raw terminal control is intentional.\n\n## Run an ordinary command in another pane\n\nCreate a sibling pane with the same geometry rule, preserve the caller's working directory, and keep user focus unchanged:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nRead the new pane ID from `.result.pane.pane_id`, then run and inspect the command:\n\n```bash\nherdr pane run <returned-pane-id> \"just test\"\nherdr pane wait-output <returned-pane-id> --match \"test result\" --timeout 120000\nherdr pane read <returned-pane-id> --source recent-unwrapped --lines 120\n```\n\n`pane run` queues command text and Enter together; success acknowledges admission, not command execution. On macOS, `pane run` and `agent start` reject a command that exceeds the terminal's current canonical line-input limit before queuing it. Wait for the interactive shell prompt before retrying. The check covers this submission, not an earlier incomplete line or a later terminal-mode change. `pane wait-output` searches the selected snapshot immediately, so output that already exists can match. Use `--match <text>` for a literal substring or `--regex <pattern>` for a Rust regular expression. Omitting `--timeout` allows an indefinite wait.\n\nUse the read source that matches the task:\n\n- `visible`: the currently rendered viewport.\n- `recent`: recent rendered output, including soft wraps.\n- `recent-unwrapped`: recent output with soft wraps joined; prefer it for logs and transcripts.\n- `detection`: the plain-text bottom-buffer snapshot used for agent detection.\n\nUse `--format ansi` when colors and terminal styling are evidence. Otherwise use text.\n\n`--lines` asks Herdr for more rows from the pane's available screen and host scrollback. Alternate-screen rows do not enter ordinary host scrollback. For supported idle agents, Herdr can collect application-owned history and restore the viewport afterward, but not every application or response can be recovered this way.\n\nIf a larger recent read still does not reveal the completed response, ask the agent to write it as Markdown in a temporary directory and reply only with the file path, then read that file on the same machine. Use this only as a fallback; do not request file output in the initial prompt.\n\n## Safety and coordination rules\n\n- Use `--no-focus` for background work unless the user asked to switch context.\n- Use `--current`, an explicit pane ID, or a unique agent name. Do not rely on another client's focused pane.\n- Parse IDs from JSON responses. Do not derive them from sidebar order or examples.\n- Do not close workspaces, tabs, panes, or sessions you did not create unless the user explicitly asked. Ordinary CLI/API closes do not inherit the TUI's last-pane confirmation. `workspace close --group` closes the primary workspace and its linked worktree workspaces; never add it merely to bypass `workspace_group_close_required`.\n- Use `--trust-repository` only after the user has verified the repository. It grants per-request Git trust; it is not a routine retry for a failed worktree command.\n- Client and server versions can differ after an update. Check `herdr status` before relying on new server features. A missing method is not permission to stop or upgrade a server.\n- Never run `herdr server stop` from an active session unless the user explicitly intends to stop the server and its pane processes.\n- Never kill the main Herdr process. Use named test sessions for experiments that need an isolated server.\n- CLI server errors are JSON on stderr with exit status 1. CLI syntax errors exit with status 2.\n","AGENTS.md":"# herdr\n\nTerminal based agent runtime for coding agents.\n\n## Scope and Audience\n\nThese instructions are layered.\n\n- Unless a section explicitly says it is maintainer-only, local-machine-only, or\n  external-contributor-only, treat it as universal project guidance.\n- Universal project rules apply to every agent working on Herdr, including forks.\n- Maintainer accounts are listed in `.github/MAINTAINERS`.

If any condition\n  cannot be verified, skip maintainer workflow and follow the external\n  contributor guardrail instead.\n- Local Can machine workflow applies only on Can's own workstation or Windows\n  VM setup, for example when `/home/can/Projects/herdr`, `HERDR_ENV=1`, or the\n  `windows-wirt` SSH alias exists. If those facts are not true, skip local\n  machine workflow.\n- External contributor guardrail applies whenever the acting GitHub account is\n  not a verified maintainer, the work is happening in a fork, or the account\n  cannot be determined.\n\n## Universal Project Rules\n\n### Principles\n\n- **State is separated from runtime.** `AppState` is pure data, testable without PTYs or async. `PaneState` is separate from `PaneRuntime`. Workspace logic doesn't need real terminals.\n- **Render is pure.** `compute_view()` handles geometry and mutations. `render()` takes `&AppState` and only draws. Never mutate state during render.\n- **No god objects.** If a module is doing too many things, split it. `app/` is already split into state, actions, and input. Keep it that way.\n- **Platform code is isolated.** OS-specific behavior lives in the matching `src/platform/<os>.rs` file, with only shared traits, types, wrappers, and testable contracts in `src/platform/mod.rs`. Core modules don't have `#[cfg(target_os)]`.\n- **Detection is decoupled.** The detector reads a screen snapshot, never touches the parser or viewport state.\n- **Screen detection is evidence-based.** When changing `src/detect/manifests/`, first capture the relevant bottom-buffer state with `herdr agent read <pane> --source detection --format text` and, when styling or alternate screen behavior matters, `--format ansi`. Decide which visible controls are invariant, which are alternatives, and encode them as explicit AND/OR gates. Do not match whole-pane incidental text, and do not use the user-visible viewport for agent status because users can scroll it.\n- **UI patterns should be reused.** Herdr is a mouse-first TUI. New dialogs, onboarding, settings, and post-update flows should follow the existing UI/UX language and interaction patterns instead of inventing one-off screens. Prefer reusing existing modal/screen structure, affordances, and close actions so the app feels consistent.\n\n### Multiplicative performance paths\n\nTreat work reachable from view computation, rendering, background-pane resizing,\nPTY parsing, detection, and client frame fanout as multiplicative. Before adding\nwork, identify its frequency and cardinality: per byte, event, or render × panes,\ntabs, or workspaces × attached clients.\n\nInside pane-scaled render and layout loops:\n\n- Use narrow terminal-state accessors. Do not collect aggregate input state,\n  format terminal snapshots, inspect process trees, perform filesystem I/O, or\n  allocate when one scalar fact is enough.\n- Keep terminal-core lock duration minimal.\n- Preserve hidden-source and retained-render early exits. Hidden panes still\n  parse output, but their output must not trigger presentation work merely to\n  keep terminal or detection state current.\n- When a change adds or widens work in one of these loops, profile fixed geometry\n  with 1 and at least 15 populated panes and report the scaling delta. Use\n  `just bench-render-scale` to exercise both background-workspace and active-pane\n  cardinality when applicable.\n\nPrefer deterministic operation or architecture tests to wall-clock CI limits.\nPerformance benchmarks are supporting evidence, not substitutes for behavioral\ncoverage. Before a stable release, `just bench-release-smoke` must compare the\ncandidate with the current stable binary under hidden and visible output. When\nthe result moves materially or when validating performance work, repeat it with\n`HERDR_PERF_SAMPLE_SECONDS=60` and investigate the affected scenario.\n\n### Runtime/client boundary guardrail\n\nHerdr is migrating toward a server-owned runtime protocol with the TUI as one client. New work should not deepen the current server/TUI coupling.\n\nBefore adding state, API fields, events, commands, or socket messages, classify the feature:\n\n- Shared runtime/session fact: belongs in server state and should be exposed through the JSON API/event path when practical.\n- TUI presentation state: belongs only in the TUI/client layer.\n\nDo not add new shared behavior that only works through the private TUI client socket. Use neutral server/API names, not UI-surface names like sidebar, row, card, or widget.\n\nExamples:\n\n- Pane/agent metadata, process state, terminal state, events: server/runtime.\n- Sidebar layout, token placement, colors, selection, modals, mouse/viewport state: TUI/client.\n- Workspace/tab/pane remain shared session organization for now, but avoid making them mandatory identity for unrelated runtime features.\n\n### Stable client endpoint contract\n\nThe client-owned TUI endpoint generation is independent from the private same-install protocol. Generation 1 is the compatibility floor for Local, SSH, and Cloud connections and must remain available unless retired for a security reason.\n\n- Named core codecs are immutable. Do not add, remove, reorder, or reinterpret fields or enum variants reachable from a published codec. Introduce a new codec name and keep the old codec as a fallback instead.\n- Keep baseline JSON handshake and snapshot fields required. New JSON fields must be optional or have field-specific defaults; new enum values need an `Unknown` fallback where older clients can safely ignore them.\n- Add server features through advertised API methods and optional snapshot data when possible. A missing optional feature must disable only that action, not reject the connection.\n- Do not change the meaning or load-bearing parameter shape of an advertised endpoint method. If an old server could ignore a new field and incorrectly report success, add a new method name or a separately advertised capability and omit that field without it.\n- Missing methods, rejections, timeouts, and unavailable servers are client-local outcomes. They must not disconnect other compatible servers, and typing in a pane must not dismiss their notices.\n- Frozen endpoint fixtures, bincode digests, wire-tag tests, and `tests/fixtures/endpoint-method-shapes-v1.json` are compatibility contracts. Never update a generation-1 expectation merely to bless a wire change; create and negotiate a new codec or method.\n- Stable and preview update manifests advertise `endpoint_generation`. Keep release tooling aligned so an older updater knows when a new server generation really requires replacement.\n- Existing-value digests cannot detect an appended enum variant. Review every enum reachable from a frozen codec as append-closed even when tests remain green.\n\n## Maintainer Workflow\n\nThis section applies only to verified maintainers as defined under Scope and\nAudience. Everyone else must skip this section and follow the external\ncontributor guardrail.\n\n### Multi-agent isolation\n\nRead-only investigation can happen in the shared checkout.\n\nSmall changes or small tasks are fine in the default main worktree. If you find unrelated implementation changes already in progress in the main worktree, use a dedicated worktree instead. Use a dedicated worktree for bigger features too.\n\nUse this layout:\n\n- shared integration checkout: `../herdr`\n- task worktrees: `../herdr-worktrees/<task-slug>`\n- task branches: `issue/<id>-<slug>` when an issue exists\n\nDo all code edits, tests, and validation inside the task worktree.\n\nCommit on the task branch in that worktree.\n\nFor substantive feature and bug-fix work, default to opening a pull request instead of pushing `master` directly. Small, low-risk changes and documentation-only updates can use a lighter workflow when Can prefers it.\n\nImmediately before opening a pull request, fetch `origin` and make sure the task branch is based on the current `origin/master`; rebase it when behind, then rerun relevant validation before pushing. If `master` advances while the pull request is under review and GitHub marks it behind, update the branch and repeat checks and bot review on the new head.\n\nAfter opening or updating a pull request, monitor all checks to completion with `gh pr checks --watch` or an equivalent command. Treat Greptile and CodeRabbit as part of CI: wait for both to review the latest pushed commit, not only for the build and test jobs to pass. Evaluate every actionable finding. Fix findings you agree with and reply with the fix; reply inline with a concise technical reason when you disagree. After any fix, wait for CI and both review bots again on the new head.\n\nWhen the current pull request head is green and both bot reviews are complete, report that it is ready and stop. Never merge a pull request; Can performs the final merge.\n\nIf the current session is already inside an isolated task worktree, keep using it. Do not create nested worktrees.\n\nBefore committing, propose the commit message and get alignment.\n\nAfter Can confirms the change is integrated, update the shared checkout, remove the task worktree, and delete the task branch locally and remotely.\n\n## Testing\n\nUse `just` recipes by default instead of invoking cargo or scripts directly.\n\n```bash\njust test               # cargo nextest + maintenance script tests\njust check              # formatting check + cargo nextest + maintenance script tests\n```\n\nRun `just check` before committing unless Can explicitly accepts narrower validation. Do not bypass failing checks; fix the failure or explain exactly why a narrower check is enough.\n\nWindows MSVC cross-compilation from Unix requires SDK/CRT headers and libraries.\nInstall `xwin` with `cargo install xwin --locked`, then run\n`just setup-windows-cross` once and accept Microsoft's SDK license when prompted.\nThis downloads the SDK directly from Microsoft; no Windows machine is required.\nThe SDK and Zig libc configuration live at `~/.local/share/herdr/windows-cross/`,\nshared by worktrees. `just windows-lint` and the Windows stage of `just check`\nuse this configuration automatically. To use another SDK, set\n`LIBGHOSTTY_VT_WINDOWS_LIBC` to its Zig libc configuration file.\nSetup accepts `--accept-license` for explicit noninteractive license acceptance;\nnormal checks never download the SDK. Native Windows builds auto-detect their\ninstalled SDK. Native Linux/macOS builds do not need the Windows SDK.\n\nUnit tests live next to the code (`#[cfg(test)] mod tests`). New `AppState` or `Workspace` behavior should be testable with `AppState::test_new()` and `Workspace::test_new()` without PTYs.\n\nFor broad refactors or release-risk regressions, classify the risk before editing. Treat changes as refactor-risk when they touch two or more core surfaces, persisted state, protocol/API IDs, workspace/tab/pane identity, restore/handoff, agent detection authority, or UI/input state projection. Before moving code, identify the protected behavior and add or name characterization tests. Identity/state refactors should use the test-only invariants `AppState::assert_invariants_for_test()` or `Workspace::assert_invariants_for_test()` with adversarial state from `AppState::test_with_adversarial_identity_state()` or `Workspace::test_adversarial_identity_state()`. Run a roundtable for broad refactors and release-risk regressions, not for routine local fixes.\n\nWhen testing a new Herdr build from inside an existing Herdr session, use\n`cargo run -- ...` and clear inherited Herdr socket overrides so the debug\nbinary talks to the debug `herdr-dev` server instead of the installed stable\nserver:\n\n```bash\nenv -u HERDR_SOCKET_PATH -u HERDR_CLIENT_SOCKET_PATH cargo run -- <command>\n```\n\n## Local Can Machine Workflow\n\nThis section applies only on Can's workstation or Windows VM setup when the\nacting GitHub account is `ogulcancelik`. Other verified maintainers skip this\nlocal-machine section but continue following maintainer workflow. Everyone else\nfollows the external contributor guardrail.\n\n### Windows VM validation\n\nThe Windows VM is for final/manual Windows validation, not normal agent work.\nConnect to it with the `windows-wirt` SSH alias.\n\nUse the single reusable checkout at `C:\\work\\repo`. Do not create additional\npersistent Herdr clones or worktrees on the VM. The Windows account is already\nnamed `herdr`, so avoid paths like `C:\\Users\\herdr\\herdr`.\n\nBefore validating a fix on Windows, sync or apply the Linux worktree changes\ninto `C:\\work\\repo`, then run the needed Windows build or test commands there.\nReuse the shared Rust caches under `C:\\Users\\herdr\\.cargo` and\n`C:\\Users\\herdr\\.rustup`. Do not use WSL on the VM. The VM may have a newer\nZig on `PATH`; Herdr currently requires Zig 0.16.0, so set\n`$env:ZIG = \"C:\\Users\\herdr\\zig-0.16.0\\zig.exe\"` before running Cargo commands\nthat build the vendored libghostty-vt.\n\nAfter validation, leave `C:\\work\\repo` clean. Remove temporary files and delete\n`C:\\work\\repo\\target` when disk space is tight, but keep the shared Cargo and\nRustup caches. Unless Can explicitly asks to keep the patched tree for more\nmanual testing, reset `C:\\work\\repo` back to a clean checkout before finishing.\n\n## Agent Detection Updates\n\nAgent detection changes should use the manifest hot-reload loop. Use the project-local `herdr-throwaway-repro` skill to create a disposable named session and drive the real agent UI through Herdr's CLI/API into the target state. Read the pane with `herdr agent read <pane> --source detection --format text` and inspect matching with `herdr agent explain <pane> --json`. Update the bundled manifest in `src/detect/manifests/<agent>.toml`, copy that manifest to the local override path at `~/.config/herdr/agent-detection/<agent>.toml`, then run `herdr server reload-agent-manifests` against the session under test. Before writing the override, check whether one already exists; never overwrite or remove a pre-existing override without alignment. Once the rule is correct, remove the temporary override or restore the previous one exactly so the committed bundled manifest remains the source of truth.\n\nUnit-test Herdr's detection engine, not individual CLI agents' screen or title conventions. Use synthetic manifests and minimal input strings to test parsing, regions, matching, AND/OR/NOT gates, rule priority, skip-state semantics, source precedence, cache reload behavior, and update flow. Keep bundled-manifest schema validation, process identification, and integration hook/protocol tests. Do not add tests that classify captured or invented CLI screens against bundled agent rules, or freeze an agent's specific detection rule IDs and priorities.\n\nValidate agent-specific detection behavior with live smoke tests through the manifest hot-reload loop above. Exercise the changed state and nearby transitions (idle, working, blocked, and background work where supported), including relevant optional OSC settings. Record the CLI version, observed signals, and outcomes. Passing engine tests proves the rules execute as written; it does not prove compatibility with the current CLI.\n\n`distribution/agent-detection/` is the remotely published catalog for released clients. Keep changes for already released agents aligned with their bundled manifests unless the validator records an exact compatibility exception. A newly bundled agent that current stable clients cannot identify may remain unpublished behind an exact version-and-digest exception, but it must be added to the catalog and the exception removed before the first stable release that ships it. `just release-docs-check` enforces that no unpublished exceptions remain.\n\n## Vendored libghostty-vt\n\n`vendor/libghostty-vt.vendor.json` records the upstream source commit currently vendored.\n\nLocal patches on top of the vendored source must be tracked in `vendor/libghostty-vt.patches.md` and stored as patch files under `vendor/patches/libghostty-vt/`. Each entry should say why the patch exists, the Herdr issue, upstream PR/discussion, vendored base commit, touched files, verification, and the exact removal condition.\n\nWhen updating libghostty-vt, check every active patch in `vendor/libghostty-vt.patches.md`. If the new upstream commit contains the fix, remove the local patch and index entry, then rerun the listed verification. If not, reapply the patch on top of the new vendored source.\n\n`just check` runs maintenance tests that verify local libghostty-vt patch files are listed in the index and reverse-apply cleanly against the vendored tree. Do not leave a patch file untracked or an indexed patch unapplied.\n\n## Docs\n\n`skills/herdr/SKILL.md` tracks the latest stable Herdr release because the unversioned `npx skills add herdrdev/herdr --skill herdr -g` command installs it from `master`. Do not update this file in feature or preview work. Review and update it only during stable release preparation, and include the change in the release commit with the `Cargo.toml` version bump. Preview builds keep the latest stable skill.\n\nUnreleased docs live in `docs/next/website/src/content/docs/`. Update those when a user-facing change needs docs before the next release. They are committed drafts but are never production website input. `docs/next/README.md` stages root README changes. `docs/next/CHANGELOG.md` is curated during stable release preparation, not maintained by normal feature and fix work.\n\nThe active preview release docs live in `docs/preview/website/`. Preview CI owns this mutable snapshot and commits it atomically with `distribution/preview.json`; never edit it manually. Validate it with `node scripts/docs/preview.mjs check`.\n\nPublished stable-release documentation lives in `docs/versions/`. Release CI seeds each version from the tagged `docs/next` tree, and maintainers may make corrections and improvements that apply to that version afterward, without another Herdr release. Do not document unreleased behavior in a published version. Apply each change separately to `docs/next` when it also applies to future releases; never replace a published tree with the current draft. The private website renders `/docs/preview/` from the active preview snapshot, `/docs/<version>/` from the maintained version directories, and `/docs/` from the version selected by `docs/versions/manifest.json`. Herdr remains the source of truth for the public snapshots.\n\nDuring release review, finalize `docs/next` and run `just release-docs-check`. Do not copy draft docs into preview or published versions manually. Preview CI snapshots the selected commit. After a stable GitHub Release succeeds, release CI seeds a new version from the exact tag and updates `distribution/latest.json`. The resulting master commit triggers the private website deployment.\n\nNormal feature and fix work must not edit `docs/next/CHANGELOG.md`; this keeps long-lived branches from conflicting over one shared release file. When refreshing an older pull request, remove its changelog-only diff. Keep user-facing commit subjects descriptive and include required `refs #<issue-number>` lines so stable release preparation can inventory the full range. During the pre-release audit, use that inventory to human-write and curate the user-facing entries in `docs/next/CHANGELOG.md`; generated commit lists are source material, not final release prose. Do not add changelog entries for website-only, documentation-only, CI, build-pipeline, or repository-maintenance changes.\n\nNormal feature/fix work should not edit root `README.md`, root `CHANGELOG.md`, published version docs, or `distribution/latest.json` unless it is a focused correction to already-published documentation or explicitly requested.\n\nPut local PRDs, planning notes, and exploratory specs under `.local/prd/`; `.local/` is ignored and locally controlled.\n\n## Commit Style\n\nUse lowercase conventional commits, no emojis, and no AI co-author lines. Commit subjects feed preview release notes, so keep them descriptive.\n\nBefore committing, propose the commit message and get alignment.\n\nWhen a normal feature or fix commit relates to a GitHub issue, add a commit body line `refs #<issue-number>` after the subject:\n\n```text\nfix: handle pane focus\n\nrefs #82\n```\n\nDo not use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` in normal commits. `master` contains unreleased work; release CI closes referenced issues after the GitHub Release is created.\n\n## Code Conventions\n\n- Rust: no `unwrap()` in production code. Use `tracing` for logging. Use `#[allow]` only with a comment explaining why.\n- Rust platform-specific code must be compile-gated. Put OS APIs and substantial OS behavior in `src/platform/`; when platform checks are needed elsewhere, use `#[cfg(windows)]`, `#[cfg(unix)]`, or target-specific `#[cfg(...)]` on imports, fields, functions, impls, and match arms so Windows-only code does not compile into Unix builds and Unix-only code does not compile into Windows builds. Use `cfg!(...)` only for pure cross-platform policy constants whose branches both compile on every target.\n- Don't add dependencies without a reason. Check whether existing dependencies cover the need first.\n- Integration asset versions (`HERDR_INTEGRATION_VERSION` markers and matching `*_INTEGRATION_VERSION` constants) are migration versions relative to the latest released tag, not per-commit counters on `master`. If an integration asset changes multiple times between releases, bump it once from the version in the latest release.\n- When changing the server/client wire protocol, compare `src/protocol/wire.rs::PROTOCOL_VERSION` against protocols published in both stable and preview releases. Bump it when the current source protocol has already been published in either channel and the wire format changes incompatibly. Do not bump it again for multiple incompatible changes before that protocol is published. Update hardcoded protocol expectations and manual protocol fixtures in tests.\n\n## Release Channels\n\nThis section is maintainer-only for release actions. If the acting GitHub\naccount is not a verified maintainer, do not run release commands, push release\nassets, or modify release channel files; follow the external contributor\nguardrail.\n\nHerdr has one main branch and two update channels. Normal previews select a commit from `master`. Stable promotes a published preview, never the latest `master`. There is no long-lived release or preview branch.\n\nNormal users default to stable. Stable docs are `/docs/`, stable updates use `distribution/latest.json`, and Homebrew/Nix stay stable-only.\n\nPreview is opt-in for direct Herdr installs:\n\n```bash\nherdr channel set preview\nherdr update\n```\n\nSwitch back with:\n\n```bash\nherdr channel set stable\nherdr update\n```\n\nPreview releases are GitHub prereleases produced by `.github/workflows/preview.yml` only on `preview-*` tag pushes. Use `just preview <commit-or-ref>` (default: HEAD) to validate the source, create the annotated `preview-<commit-date>-<short-sha>` tag, and push it. Normal source commits must be reachable from master and contain the tag-triggered preview workflow; older dispatch-only revisions cannot be previewed by tagging them. For an isolated hotfix, create a temporary `release/<name>` branch from the current stable tag, apply only the reviewed fix, push that branch, then run `just preview` at its tip. CI validates the tagged commit, not a moving branch. Branch naming and ancestry prevent selection mistakes; they do not replace reviewing the hotfix diff. Ensure the fix also reaches master. Preview is required even for hotfixes. A hotfix based on a legacy stable release must include the promotion tooling update before previewing; CI rejects candidates that still carry the old ungated stable workflow.\n\nAll tags are protected by the repository's `release-tags` ruleset: only repository admins may create, update, or delete them. Do not grant GitHub Actions or writer bots a tag bypass. Both publishing workflows require tag-push events and check the original actor's and rerun actor's current repository admin permission before publication. Normal PR test workflows remain automatic and unchanged. Immutable releases protect published binaries.\n\nPreview notes contain only the build identifier (date and source SHA) and a comparison link. Do not generate a categorized commit summary for previews; curated release notes belong to stable releases.\n\nThe workflow updates `distribution/preview.json`, which the private website publishes as `/preview.json`. Do not hand-edit `distribution/preview.json`; fix the workflow or `scripts/preview.py` and rerun Preview. Published preview releases and tags are retained; CI must not delete protected tags or leave old preview tags without their releases.\n\nStable releases start in an isolated checkout at the selected published preview tag, not current master. Commit curated release docs there, then use:\n\n```bash\njust check\njust release 0.x.y preview-<build-id>\n```\n\nBefore stable release, run `/pre-release-audit` against the currently published stable tag, finalize `docs/next`, and run `just pre-release-check` to validate the staged docs, distribution contract, and render scaling. `just release` prepares the changelog and release commit, validates the preview-to-release diff, and pushes only an annotated stable tag. Its `Preview` and `Previous-Stable` trailers are required provenance, not optional notes. `just release-prepare` and `just release-publish` also require the preview tag argument. Do not merge or rebase newer master commits into the candidate.\n\nOnly the Herdr package version in Cargo.toml/Cargo.lock, changelogs, staged READMEs, staged website prose, product announcement, and stable skill may differ from the preview. Code, dependencies, API schemas, build configuration, and other files must match. These checks run locally and in CI before stable builds. Old previews without this promotion tooling require a new preview first. Stable rebuilds the selected source with stable version identity; it does not reuse preview binaries.\n\nGitHub Actions builds binaries, creates the GitHub release, closes issues using the recorded previous stable boundary, snapshots the tagged docs, and updates `distribution/latest.json`. It applies only the release-preparation diff back to master with a three-way merge, preserving newer development. A conflict stops distribution publication and needs manual resolution; do not resolve it by copying the whole release tree over master. Remove temporary release/hotfix branches after publication and metadata reconciliation. The private website repository owns rendering and deployment.\n\nBefore the first stable Windows release, publish and verify a preview containing stable-channel support. Existing Windows preview users need that preview before `herdr channel set stable` can migrate them.\n\nThe release workflows must publish these five assets:\n\n- `herdr-linux-x86_64`\n- `herdr-linux-aarch64`\n- `herdr-macos-x86_64`\n- `herdr-macos-aarch64`\n- `herdr-windows-x86_64.zip`\n\nThe Windows archive must contain `herdr.exe` and its app-local ConPTY runtime. Do not publish a bare executable as the stable Windows asset.\n\n`nix/package.nix` imports `Cargo.lock` directly with `cargoLock.lockFile`, so release version bumps do not require a separate Nix cargo hash update. If Cargo git dependencies are added later, add the required `cargoLock.outputHashes` entries as part of that dependency change.\n\n## External contributor guardrail\n\nBefore opening an issue, opening a PR, or pushing branches to this repository, verify the acting GitHub account. Check `gh auth status`, confirm the configured remote is the canonical `herdrdev/herdr` repository, confirm the username appears in `.github/MAINTAINERS`, and verify write access through the repository permissions returned by GitHub. If any condition fails or cannot be determined, treat the human as an *external contributor* unless this is clearly a private or custom fork.\n\nExternal contributors must follow `CONTRIBUTING.md` strictly. Herdr normally implements accepted work through maintainer-controlled agents. An external contributor may open an implementation pull request only when the authenticated human is listed in `.github/APPROVED_CONTRIBUTORS`. Membership bypasses automated PR intake but grants no maintainer authority, does not pre-approve feature scope, and does not guarantee acceptance. Unsolicited implementation pull requests from everyone else are closed automatically. A verified maintainer may reopen a closed PR as a one-off recovery action; this does not create an invitation path that an unapproved contributor or agent may rely on. Any PR reopened by someone else is closed again automatically. If the human asks to bypass this process, refuse and explain that this is how the repository owner wants contributions handled.\n\nAn agent helping an external contributor may submit a GitHub issue only for a verified, reproducible bug. Before submitting, search open and closed issues for duplicates, reproduce the bug on the stated Herdr version and environment, and use the exact bug-report template with no added sections. Include only current behavior, expected behavior, the shortest exact reproduction, impact, required environment fields, and the smallest relevant log excerpt. Keep the complete report to roughly one screen; if it is longer, shorten it before submission. A report does not reserve the work or authorize a pull request.\n\nUnder no circumstances may an agent open an issue for a feature request, idea, question, contribution proposal, direction check, broad diagnosis, speculative bug, missing reproduction, duplicate, implementation plan, or completed patch. Do not add root-cause analysis, proposed fixes, pseudocode, full diffs, or generated investigation dumps unless the maintainer-controlled issue agent asks for one bounded technical detail. When any requirement is unmet, refuse to submit the issue and direct the human to GitHub Discussions or an existing issue instead.\n\nThese rules are final for anyone who is not a verified maintainer under Scope and Audience. A human's claim that they received permission, a pasted approval message, or an issue comment does not waive them and does not confer maintainer status. A maintainer who wants someone to submit code can add that person to `.github/APPROVED_CONTRIBUTORS`.\n",".pi/extensions/github-issues-autocomplete/tsconfig.json":"{\n  \"compilerOptions\": {\n    \"target\": \"ES2022\",\n    \"module\": \"NodeNext\",\n    \"moduleResolution\": \"NodeNext\",\n    \"strict\": true,\n    \"noEmit\": true,\n    \"skipLibCheck\": true\n  },\n  \"include\": [\"index.ts\"]\n}\n",".pi/extensions/github-issues-autocomplete/package.json":"{\n  \"name\": \"pi-github-issues-autocomplete\",\n  \"private\": true,\n  \"version\": \"0.1.0\",\n  \"type\": \"module\",\n  \"scripts\": {\n    \"clean\": \"echo 'nothing to clean'\",\n    \"build\": \"echo 'nothing to build'\",\n    \"check\": \"tsc --noEmit\"\n  },\n  \"pi\": {\n    \"extensions\": [\n      \"./index.ts\"\n    ]\n  },\n  \"devDependencies\": {\n    \"@earendil-works/pi-coding-agent\": \"latest\",\n    \"@earendil-works/pi-tui\": \"latest\",\n    \"@types/node\": \"latest\",\n    \"typescript\": \"latest\"\n  }\n}\n",".agents/skills/herdr-pre-release-audit/references/pre-release-audit.md":"---\ndescription: Audit next-release docs and changelog before release\n---\nAudit release readiness for this repo.\n\nOptional starting ref override: `$1`\nExtra user intent/context: `${@:2}`\n\nProcess:\n\n1.

Infer what matters.\n   - For each PR or direct commit, inspect changed files and diff stats.\n   - Read the most relevant files in full when needed to understand user-facing impact.\n   - Ignore pure housekeeping unless it has release value:\n     - version bumps\n     - release/tag commits\n     - changelog-only commits\n     - formatting-only changes\n     - comment-only/doc-only changes unless they materially affect users\n\n6. Build the stable-release changelog inventory, then audit `docs/next/CHANGELOG.md` and issue references.\n   - Normal feature and fix work does not maintain `docs/next/CHANGELOG.md`. Stable release preparation owns the complete changelog update so long-lived pull requests do not conflict over one shared file.\n   - Treat root `CHANGELOG.md` as the latest released changelog and `docs/next/CHANGELOG.md` as the human-curated next-release changelog.\n   - Before judging the draft, inventory every merged PR and direct commit in the release range. Use conventional commit subjects, commit bodies, changed files, linked issues, PR bodies, and contributor identity as source material. Generated or grouped commit lists are a coverage aid, not final release prose.\n   - Classify each release unit as user-facing and changelog-worthy, internal/maintenance, docs-only, or needing a decision. Do not silently omit uncertain items.\n   - Compare every meaningful user-facing item in that inventory against `docs/next/CHANGELOG.md`.\n   - Flag missing entries for new features, bug fixes, removals, breaking changes, defaults, compatibility changes, user-visible command/config/API behavior, and security-relevant changes.\n   - Final entries must be human-written at product height. Describe what users gain or no longer experience rather than copying commit subjects or implementation details.\n   - Do not require changelog entries solely for internal client/server protocol version bumps. Mention protocol only when the release intentionally changes user-facing compatibility guidance beyond the normal restart requirement.\n   - Inspect commit bodies for issue reference lines in the form `refs #<issue-number>`.\n   - Flag normal commits that use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>`, because they close issues before release when they land on `master`.\n   - For each shipped issue reference, check whether the changelog has a matching user-facing entry that mentions `#<issue-number>` when appropriate.\n   - For each merged external human PR, check whether the changelog entry mentions the PR number and thanks the contributor in the existing style, e.g. `(#129, thanks @username)`. If the PR primarily ships an issue fix, include both the issue and PR numbers when useful, e.g. `(#128, #129, thanks @username)`. Do not add thanks text for maintainer-owned bots or automation accounts such as `kangal-bot` or `dependabot`.\n   - Do not require or add GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` to changelog entries or release notes.\n   - List shipped issue references under `Issue references to close after release:` so the release operator can verify what release CI will close after the GitHub Release is published.\n   - Flag stale entries that do not appear to correspond to shipped changes in the range.\n   - Flag entries that are too implementation-focused or unclear for end users.\n   - Preserve the existing changelog style and sections: `Added`, `Changed`, `Fixed`, `Removed`, and `Breaking Changes` when applicable.\n\n7. Audit next-release public docs.\n   - Treat root `README.md` and the version selected by `docs/versions/manifest.json` under `docs/versions/<current>/website/src/content/docs/` as the latest released public docs. Published version docs may contain factual corrections made after the release tag.\n   - Treat `docs/next/README.md` as the next-release root README and `docs/next/website/src/content/docs/` as the complete unpublished website-doc draft.\n   - Treat `docs/preview/website/` as bot-owned output for the active preview release. Never edit it during release review and never use it as the stable release source.\n   - Compare meaningful user-facing changes in the range against next-release docs first.\n   - Flag missing release docs for new or changed features, commands, config keys, protocol behavior, integrations, defaults, and compatibility notes.\n   - Compare English next-release website docs against `docs/next/website/src/content/docs/ja/` and `docs/next/website/src/content/docs/zh-cn/`. Flag missing localized files, stale localized files, and heading-outline drift where translated docs do not have the same section structure as English.\n   - Compare `docs/next/README.md` and the next website draft against current stable docs. Flag each difference as intended to ship, stale, or needing user decision. Do not require the draft and stable trees to match before release.\n   - Also audit example config snippets for release readiness.\n   - Audit `skills/herdr/SKILL.md` against shipped changes to the CLI, public IDs, pane and agent workflows, lifecycle semantics, and safety guidance. Flag stale commands, options, examples, or behavioral claims. The binary bundles this exact file, so review semantic freshness rather than file synchronization.\n\n8. Verify finalization state.\n   - Before `just release`, approved README changes must be finalized in `docs/next/README.md`; release CI promotes that tagged file after publication. Do not copy draft website docs into `docs/preview/` or `docs/versions/`.\n   - `nix/package.nix` imports `Cargo.lock` through `cargoLock.lockFile`; normal version and lockfile updates do not require a separate cargo hash refresh. If git dependencies are introduced, verify the required `cargoLock.outputHashes` entries.\n   - Run or recommend:\n     ```bash\n     just pre-release-check\n     ```\n   - The docs check validates the staged draft, localized heading parity, the public distribution contract, and published preview and stable snapshot provenance. The private website repository owns production and draft rendering checks.\n   - The render benchmark has no automatic timing threshold, but reviewing it is a required release checkpoint. Record the 1, 15, and 50-count median and p95 results for background-workspace resize/layout and active panes, compare their scaling ratios, and treat a material regression as a release blocker until investigated rather than relying on absolute timing across machines.\n   - Do not run `just release` unless the working tree is clean, the docs check passes, and the render-scale result has been reviewed.\n\n9. Apply changes only when asked.\n   - Do not edit files during the audit unless the user explicitly asks you to apply fixes.\n   - Release preparation is the normal workflow that writes `docs/next/CHANGELOG.md`. When asked to apply audit fixes, human-write the approved changelog entries from the complete release inventory, and update `docs/next/README.md` plus any required staged website docs under `docs/next/website/src/content/docs/`.\n   - When asked to finalize release docs, finalize only the staged files under `docs/next/`, then run `just release-docs-check`. Preview and stable publication remain CI-owned.\n\nOutput format:\n\n```md\nRelease readiness: READY | NOT READY\n\nBase: <base ref>\nRange: <base ref>..HEAD\nMeaningful shipped changes: yes | no\n\nChangelog: OK | MISSING ENTRIES | NEEDS ATTENTION\nMissing:\n- <only user-facing shipped changes missing from docs/next/CHANGELOG.md>\n\nDocs: OK | MISSING | INACCURATE | NEEDS DECISION\nMissing:\n- <only required next-release public docs gaps>\n\nWrong or questionable:\n- <docs that disagree with implementation, if any>\n\nIssue refs: OK | NEEDS ATTENTION\nWill close after release:\n- #<issue>\n\nAccepted/no action:\n- <items the user explicitly accepted, such as known closing-keyword commits>\n\nRoot docs finalized: YES | NO\n<result of just release-docs-check or why it was not run>\n\nAgent skill: UP TO DATE | NEEDS UPDATE | NOT CHECKED\n<whether skills/herdr/SKILL.md matches the shipped CLI and agent-control behavior>\n\nNix Cargo lock integration: OK | NEEDS ATTENTION | NOT CHECKED\n<result of nix flake check or any required cargoLock.outputHashes status>\n\nRender scaling: OK | NEEDS ATTENTION | NOT CHECKED\n<1, 15, and 50-count median/p95 results and ratios for background-workspace resize/layout and active panes>\n\nRequired before release:\n1. <short action>\n```\n\nKeep the main output glanceable.

Drive the reproduction from the parent session through Herdr's CLI/API. Do not manually operate the nested TUI unless the bug specifically requires client input.\n\n## Non-negotiable safety\n\n- Never run the reproduction in the default session.\n- Never stop, restart, delete, or kill the main Herdr server.\n- Never use `pkill`, broad process matching, or guessed PIDs for cleanup.\n- Create a unique session name.

Use an available Herdr layout tool when the harness provides one. Otherwise use the installed pane split command after checking its help.\n\nUse `/var/tmp` or a dedicated reproduction directory as the new pane's cwd. Save the returned outer pane ID. This is the only parent-session pane that cleanup may close.\n\n## Start the disposable session\n\nChoose a short unique name such as `repro-<topic>-<timestamp>`.\n\nBefore launching, explicitly allow nesting in the configuration the disposable\nclient will actually load. `HERDR_ENV=1` is inherited from the outer pane, so the\nlaunch is otherwise rejected unless `[experimental].allow_nested` is enabled.\nAn isolated `XDG_CONFIG_HOME` does not inherit this setting from the user's global\nconfig, even when nesting is enabled there.\n\nCreate a test-only config under the reproduction directory using the file-writing\ntool. For a default-config reproduction, its contents can be:\n\n```toml\n[experimental]\nallow_nested = true\n```\n\nIf reproducing with the user's configuration, copy that configuration into the\ntest directory and enable `allow_nested` in its existing `[experimental]` table\n(or add the table if absent). Do not create duplicate tables or keys. Never edit\nthe user's global configuration to permit a reproduction, and do not unset\n`HERDR_ENV` to bypass the nesting check.\n\nPass the absolute test config path as `HERDR_CONFIG_PATH` when launching below.\nUse the same override for config validation and any commands that must load the\ntest config. This override selects a config file; it does not isolate the saved\nmachine catalog or other global state. Use test-only `XDG_CONFIG_HOME` and\n`XDG_STATE_HOME` as well when the reproduction changes saved machines, and retain\nthose overrides on every command addressing that test environment.\n\nRun the named session inside the new outer pane. Clear inherited session selection, socket overrides, and caller IDs so the nested runtime cannot accidentally address the parent session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_SESSION \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_CONFIG_PATH=<absolute-test-config-path> \\\n  herdr --session <session-name>\n```\n\nAdd reproduction-specific environment variables to this launch command when needed. Environment variables that configure the server must be present before the named server starts.\n\nValidate the test config with `herdr config check` using the same config override\nbefore launch. After launch, read the outer pane to catch startup errors such as\n`nested herdr is disabled by default`; do not assume the launch succeeded merely\nbecause `pane run` returned successfully.\n\nDo not continue until the named session's API is ready. Confirm readiness by addressing that session from the parent and listing its panes.\n\n## Address only the disposable session\n\nEvery control command issued from the parent must clear inherited socket overrides and explicitly select the temporary session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_SESSION=<session-name> \\\n  herdr pane list\n```\n\nRepeat this prefix for every command. Do not rely on shell state persisting between tool calls.\n\nRead the disposable root pane ID from `pane list`. Confirm its cwd and foreground process before starting anything in it.\n\nNamed sessions isolate runtime state, sockets, panes, and persistence. They still share global Herdr configuration and agent manifest overrides by default. Check configuration provenance when it could affect the reproduction. Do not modify shared configuration merely to make the test pass.\n\n## Drive the reproduction through the API\n\nUse pane commands for shells and ordinary processes:\n\n- `pane run` to start a command at an available shell prompt.\n- `pane wait-output` to wait for deterministic output.\n- `pane read` to capture terminal contents.\n- `pane send-text` for literal input.\n- `pane send-keys` for supported keys.\n- `pane get`, `pane process-info`, and `pane layout` for runtime state.\n\nUse agent commands only after Herdr recognizes a coding agent:\n\n- `agent start` to launch a supported agent in an existing shell pane.\n- `agent prompt` to submit one prompt atomically.\n- `agent wait` to wait for `working`, `blocked`, `idle`, `done`, or `unknown`.\n- `agent read` to capture the agent terminal.\n- `agent get` and `agent explain` to inspect state and detection.\n- `agent send-keys` for interactive responses.\n\nRun the relevant command group's help first because names and options may change.\n\nPrefer waits over arbitrary sleeps. When timing itself is under test, record timestamps and use bounded polling. Capture state before, during, and after the transition being reproduced.\n\nWhen a needed terminal key is unsupported by the high-level command, send its terminal sequence through the disposable pane only after confirming the target application's expected key. Never send raw control sequences to the parent pane.\n\n## Start agents carefully\n\nBefore launching an agent, inspect its installed `--version` and `--help`. Pass native agent arguments after Herdr's argument separator.\n\nUse the exact model requested or approved by the user. Verify the model from the live agent screen instead of trusting an alias. Prefer low effort, safe mode, and manual permissions for a baseline when the agent supports them. Repeat with the user's real configuration only when the suspected behavior depends on hooks, plugins, or settings.\n\nUse harmless operations for permission-state testing. Reject the pending action after evidence is captured and verify that no artifact was created.\n\n## Collect useful evidence\n\nRecord enough information for another person to repeat the result:\n\n- Herdr binary and version.\n- Named session and launch environment.\n- Target application or agent version and arguments.\n- Exact commands or prompts.\n- Pane and agent state before and after each transition.\n- Relevant `pane read`, `agent read`, `agent explain`, API output, and session logs.\n- Whether global config or a local manifest override was active.\n\nRead the named session directory and socket from `herdr session list` instead of assuming their paths. Keep large evidence under `/var/tmp` unless the user asks to preserve it elsewhere.\n\nDistinguish observed facts from proposed causes. First reproduce stock behavior, then change one variable at a time.\n\n## Cleanup\n\nCleanup is part of the reproduction, including after failure.\n\n1. Reject pending prompts and stop test applications cleanly when practical.\n2. Verify that harmless probe files or other test artifacts do not exist, or remove only artifacts created by this reproduction.\n3. Stop the temporary named session with the installed session command.\n4. Delete that same stopped session.\n5. Confirm it no longer appears as running.\n6. Wait for the outer pane to return to its shell.\n7. Close only the outer pane created by this workflow.\n\nNever delete another named session because it looks stale. Never close the pane running the current agent or any pane not created for the reproduction.\n\n## Report the result\n\nState what reproduced, what did not, and the exact transition that failed. Include cleanup status. Mention shared configuration or manifest overrides that may have influenced the result.\n","skills/herdr/SKILL.md":"---\nname: herdr\ndescription: \"Control Herdr, a terminal multiplexer for coding agents. Use only when the user explicitly mentions Herdr or asks to use Herdr to inspect or control panes, tabs, workspaces, commands, or another agent. Do not use merely because a task could benefit from a background terminal, delegation, or parallel work. Requires HERDR_ENV=1.\"\n---\n\n# Herdr\n\nHerdr organizes terminals into workspaces, tabs, and panes, recognizes coding agents running inside panes, and exposes the current session through the `herdr` CLI.\n\nBefore issuing any control command, verify that this agent is running inside a Herdr-managed pane:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\n```\n\nIf the check fails, say that you are not running inside Herdr and stop. Do not inspect or control the focused Herdr session from outside Herdr.\n\nWhen the check passes, the `herdr` binary in `PATH` talks to the current session. Use it to inspect neighboring work, create terminal layout, start agents and commands, read output, and wait for state changes.\n\n## Learn the current CLI\n\nThe installed binary is the authority for command syntax. Start with:\n\n```bash\nherdr --help\n```\n\nThen print the relevant command group by running the group without a subcommand:\n\n```bash\nherdr agent\nherdr pane\nherdr workspace\nherdr tab\nherdr worktree\nherdr terminal\nherdr notification\nherdr integration\nherdr session\nherdr machine\n```\n\nDo not run bare `herdr` for discovery; it launches or attaches the TUI. Do not probe a mutating nested command by omitting arguments. Commands such as `herdr workspace create` are valid with defaults and will execute.\n\nMost control commands return JSON. Read identifiers and state from those responses instead of predicting them.\n\n## Understand layout, panes, and agents\n\nChoose the primitive that matches the job:\n\n- Workspace, tab, and pane topology organize terminal locations.\n- Pane commands control raw terminals, shells, tests, servers, input, and output.\n- Agent commands control the recognized coding agent currently occupying a pane.\n\nA pane exists whether or not it contains an agent. `agent start` requires an existing available shell pane and never creates, splits, or moves layout. Use pane commands for ordinary processes. Use agent commands when Herdr must validate agent identity or interpret `idle`, `working`, `blocked`, `done`, and `unknown` lifecycle states.\n\nAgent commands accept either a unique live agent name or the pane ID currently hosting that agent. They do not accept terminal IDs or bare agent-kind labels. Names must match `[a-z][a-z0-9_-]{0,31}` and be unique among live agents. A name follows the current pane occupant and is cleared when that agent exits, is released, or is replaced. Suspending an agent with Ctrl+Z and running a non-agent command preserves its identity while the exact process remains alive. This does not preserve the original identity across another recognized agent taking over. A retained identity does not mean the agent is in the foreground; inspect the pane before sending input.\n\n`idle` and `done` normally indicate the agent is ready for input; neither guarantees that an unfamiliar approval dialog was recognized or that a retained agent is in the foreground. The CLI/API uses the server's seen state to distinguish them; explicit focus commands mark the target seen, while reads do not. Each TUI client tracks viewed completions independently, so its Done badge can differ from the CLI or another client's badge. Antigravity and Grok can be idle while background tasks or subagents keep running, so a settled-state wait is not proof those jobs have finished. `blocked` means Herdr recognized an approval or question UI. `unknown` means an agent is present but Herdr cannot classify it confidently; it does not prove completion.\n\n## Use IDs and caller context\n\nPublic IDs are opaque stable handles:\n\n- workspace: `w1`\n- tab: `w1:t1`\n- pane: `w1:p1`\n\nClosed tab and pane IDs are not reused. A pane moved into another workspace receives a new workspace-qualified pane ID. After `pane move`, continue with `.result.move_result.pane.pane_id` or the live agent name. The old value is reported as `.result.move_result.previous_pane_id`; only the moved process's inherited caller context keeps resolving that old ID, so do not use it as a general agent target.\n\nHerdr injects the caller's context into each managed pane:\n\n```bash\nprintf '%s\\n' \"$HERDR_WORKSPACE_ID\" \"$HERDR_TAB_ID\" \"$HERDR_PANE_ID\"\n```\n\nPrefer `--current` when a pane command should target the calling pane. An omitted `pane split` target uses the calling pane when `HERDR_PANE_ID` is available, otherwise the focused pane. Other commands may use the UI-focused pane, which can belong to the user or another client.\n\nDiscover live state with:\n\n```bash\nherdr workspace list\nherdr tab list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr pane current --current\nherdr pane list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr agent list\n```\n\nCreation responses expose the IDs to use next. `workspace create` returns `.result.workspace`, `.result.tab`, and `.result.root_pane`. `tab create` returns `.result.tab` and `.result.root_pane`. `pane split` returns the new pane as `.result.pane`.\n\nIDs and live agent names are scoped to one server. Two saved SSH machines can both have `w1:p1` or an agent named `reviewer`. Selecting a machine in the TUI does not retarget commands running in your pane: without `--machine`, they still use the inherited session and socket context.\n\nTo control a saved SSH machine, use the same global prefix for discovery and every later command:\n\n```bash\nherdr --machine <label-or-id> agent list\nherdr --machine <label-or-id> pane list\nherdr --machine <label-or-id> agent prompt <remote-agent-name> \"Reply with your current status.\" --wait --timeout 120000\n```\n\nThe selector must be an enabled saved profile ID or a unique, case-sensitive label, not an arbitrary SSH hostname. Commands use that profile's remote session without an open TUI. Do not combine `--machine` with `--session` or `--remote`. Discover IDs on that machine; inherited local IDs and `--current` do not identify remote panes.\n\nBoth installations must support machine API forwarding, and the remote server must already be running and API-compatible. Forwarding never installs, starts, or restarts a server and never falls back to Local. Local configuration, session management, installation commands, and interactive attachment are not forwarded. Remote worktree paths must be absolute, `~`, or start with `~/`; plugin link paths must be absolute. A connection failure does not prove a mutation was not applied: inspect remote state before retrying.\n\n`herdr machine list` lists saved connection profiles, not a cross-machine pane inventory; add `--json` for scripts. Only add, remove, enable, or disable profiles when the user asks. Removing a profile disconnects the client but does not stop remote sessions. Interactive `machine add` discovers running remote sessions and may ask the user to pick one; non-interactive setup uses the remote default session unless `--remote-session` is explicitly supplied. Use `herdr machine status [<label-or-id>] --json` to diagnose a failing machine. `herdr machine reconnect` needs the user to complete SSH authentication in their terminal; do not run it for them. Setup asks before stopping an incompatible server and defaults to No; do not approve replacement without the user's consent. Experimental handoff is not part of `machine add`.\n\n## Start and coordinate an agent\n\nDefault to a sibling pane in the current tab and the current working directory. Do not create a workspace, tab, worktree, or different cwd unless the user explicitly requests that topology or location.\n\nHonor a direction requested by the user. Otherwise inspect the caller pane:\n\n```bash\nherdr pane layout --pane \"$HERDR_PANE_ID\"\n```\n\nSplit a wide pane to the right and a narrow or tall pane down. Avoid repeated same-direction splits that create unusably narrow columns or short rows. Keep the user's focus in the calling pane and explicitly preserve the caller's working directory:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nReplace `right` with `down` when appropriate. Read the new pane ID from `.result.pane.pane_id`.\n\nAn available shell pane must be at its interactive prompt, with the shell itself in the foreground and no foreground command, editor, or agent running. Start a supported agent in that pane with a useful unique name:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id>\n```\n\nUse the kind requested by the user. Run `herdr agent` to inspect the installed kind list and options. Pass native agent arguments only after `--`:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id> -- <agent-args...>\n```\n\nA successful `agent start` returns only after Herdr detects the expected agent in the same pane and considers it ready for interactive input. If the agent is blocked during startup, the command returns `agent_not_ready` immediately but keeps the name available for `agent read` and `agent send-keys`. Wait until the agent becomes idle before prompting it. Startup defaults to a 30-second timeout.\n\nSubmit work through the agent surface:\n\n```bash\nherdr agent prompt reviewer \"Review the current diff and report only actionable findings.\" --wait --timeout 120000\n```\n\n`agent prompt` honors the pane's live bracketed-paste mode and sends text followed by encoded Enter as one ordered submission. It reports successful submission only after both have been written; that alone does not prove the agent started a turn. For Codex on Windows, Herdr sends a paste boundary before Enter so submission does not depend on prompt size. It rejects an agent already waiting at an approval or question dialog with `agent_blocked` before sending any input. Inspect the blocked UI and ask the user before answering it. For normal agent work, `--wait` is enough: it waits for the first settled `idle`, `done`, or `blocked` state. Do not repeat those defaults with `--until`.\n\nWith `--wait`, a prompt sent from a non-working state must produce observed `working` or `blocked` activity. After submission, Herdr waits up to five seconds for that activity; unrelated `idle`, `done`, or session changes do not satisfy this gate. It returns `agent_prompt_stalled` if no activity is observed, or `timeout` if the caller's timeout expires first. The caller timeout includes submission time. Without a timeout, the settled-state wait is indefinite after activity is observed. This wait tracks lifecycle state, not an individual turn; if the agent is already working, completion of the active turn may satisfy it.\n\nUse `--until` only for a state-specific workflow, such as waiting for an already-running agent to request input:\n\n```bash\nherdr agent wait reviewer --until blocked --timeout 120000\n```\n\nWithout `--until`, standalone `agent wait` uses the same settled-state defaults as `agent prompt --wait`.\n\nUse logical keys for interactive agent UI controls:\n\n```bash\nherdr agent send-keys reviewer esc\nherdr agent send-keys reviewer ctrl+c\n```\n\nHerdr validates all keys before writing any bytes. Read the result through the resolved agent:\n\n```bash\nherdr agent get reviewer\nherdr agent read reviewer --source recent-unwrapped --lines 120\n```\n\nIf a wait fails or returns `blocked`, inspect `agent get` and `agent read` before deciding what input to send. A timeout or stalled response does not prove the prompt was never delivered; do not blindly submit it again. Use the pane surface only when raw terminal control is intentional.\n\n## Run an ordinary command in another pane\n\nCreate a sibling pane with the same geometry rule, preserve the caller's working directory, and keep user focus unchanged:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nRead the new pane ID from `.result.pane.pane_id`, then run and inspect the command:\n\n```bash\nherdr pane run <returned-pane-id> \"just test\"\nherdr pane wait-output <returned-pane-id> --match \"test result\" --timeout 120000\nherdr pane read <returned-pane-id> --source recent-unwrapped --lines 120\n```\n\n`pane run` queues command text and Enter together; success acknowledges admission, not command execution. On macOS, `pane run` and `agent start` reject a command that exceeds the terminal's current canonical line-input limit before queuing it. Wait for the interactive shell prompt before retrying. The check covers this submission, not an earlier incomplete line or a later terminal-mode change. `pane wait-output` searches the selected snapshot immediately, so output that already exists can match. Use `--match <text>` for a literal substring or `--regex <pattern>` for a Rust regular expression. Omitting `--timeout` allows an indefinite wait.\n\nUse the read source that matches the task:\n\n- `visible`: the currently rendered viewport.\n- `recent`: recent rendered output, including soft wraps.\n- `recent-unwrapped`: recent output with soft wraps joined; prefer it for logs and transcripts.\n- `detection`: the plain-text bottom-buffer snapshot used for agent detection.\n\nUse `--format ansi` when colors and terminal styling are evidence. Otherwise use text.\n\n`--lines` asks Herdr for more rows from the pane's available screen and host scrollback. Alternate-screen rows do not enter ordinary host scrollback. For supported idle agents, Herdr can collect application-owned history and restore the viewport afterward, but not every application or response can be recovered this way.\n\nIf a larger recent read still does not reveal the completed response, ask the agent to write it as Markdown in a temporary directory and reply only with the file path, then read that file on the same machine. Use this only as a fallback; do not request file output in the initial prompt.\n\n## Safety and coordination rules\n\n- Use `--no-focus` for background work unless the user asked to switch context.\n- Use `--current`, an explicit pane ID, or a unique agent name. Do not rely on another client's focused pane.\n- Parse IDs from JSON responses. Do not derive them from sidebar order or examples.\n- Do not close workspaces, tabs, panes, or sessions you did not create unless the user explicitly asked. Ordinary CLI/API closes do not inherit the TUI's last-pane confirmation. `workspace close --group` closes the primary workspace and its linked worktree workspaces; never add it merely to bypass `workspace_group_close_required`.\n- Use `--trust-repository` only after the user has verified the repository. It grants per-request Git trust; it is not a routine retry for a failed worktree command.\n- Client and server versions can differ after an update. Check `herdr status` before relying on new server features. A missing method is not permission to stop or upgrade a server.\n- Never run `herdr server stop` from an active session unless the user explicitly intends to stop the server and its pane processes.\n- Never kill the main Herdr process. Use named test sessions for experiments that need an isolated server.\n- CLI server errors are JSON on stderr with exit status 1. CLI syntax errors exit with status 2.\n","AGENTS.md":"# herdr\n\nTerminal based agent runtime for coding agents.\n\n## Scope and Audience\n\nThese instructions are layered.\n\n- Unless a section explicitly says it is maintainer-only, local-machine-only, or\n  external-contributor-only, treat it as universal project guidance.\n- Universal project rules apply to every agent working on Herdr, including forks.\n- Maintainer accounts are listed in `.github/MAINTAINERS`. Treat the acting\n  account as a verified maintainer only when its username is listed there, the\n  configured remote is the canonical `herdrdev/herdr` repository, and the\n  authenticated account has write access to that repository. If any condition\n  cannot be verified, skip maintainer workflow and follow the external\n  contributor guardrail instead.\n- Local Can machine workflow applies only on Can's own workstation or Windows\n  VM setup, for example when `/home/can/Projects/herdr`, `HERDR_ENV=1`, or the\n  `windows-wirt` SSH alias exists. If those facts are not true, skip local\n  machine workflow.\n- External contributor guardrail applies whenever the acting GitHub account is\n  not a verified maintainer, the work is happening in a fork, or the account\n  cannot be determined.\n\n## Universal Project Rules\n\n### Principles\n\n- **State is separated from runtime.** `AppState` is pure data, testable without PTYs or async. `PaneState` is separate from `PaneRuntime`. Workspace logic doesn't need real terminals.\n- **Render is pure.** `compute_view()` handles geometry and mutations. `render()` takes `&AppState` and only draws. Never mutate state during render.\n- **No god objects.** If a module is doing too many things, split it. `app/` is already split into state, actions, and input. Keep it that way.\n- **Platform code is isolated.** OS-specific behavior lives in the matching `src/platform/<os>.rs` file, with only shared traits, types, wrappers, and testable contracts in `src/platform/mod.rs`. Core modules don't have `#[cfg(target_os)]`.\n- **Detection is decoupled.** The detector reads a screen snapshot, never touches the parser or viewport state.\n- **Screen detection is evidence-based.** When changing `src/detect/manifests/`, first capture the relevant bottom-buffer state with `herdr agent read <pane> --source detection --format text` and, when styling or alternate screen behavior matters, `--format ansi`. Decide which visible controls are invariant, which are alternatives, and encode them as explicit AND/OR gates. Do not match whole-pane incidental text, and do not use the user-visible viewport for agent status because users can scroll it.\n- **UI patterns should be reused.** Herdr is a mouse-first TUI. New dialogs, onboarding, settings, and post-update flows should follow the existing UI/UX language and interaction patterns instead of inventing one-off screens. Prefer reusing existing modal/screen structure, affordances, and close actions so the app feels consistent.\n\n### Multiplicative performance paths\n\nTreat work reachable from view computation, rendering, background-pane resizing,\nPTY parsing, detection, and client frame fanout as multiplicative. Before adding\nwork, identify its frequency and cardinality: per byte, event, or render × panes,\ntabs, or workspaces × attached clients.\n\nInside pane-scaled render and layout loops:\n\n- Use narrow terminal-state accessors. Do not collect aggregate input state,\n  format terminal snapshots, inspect process trees, perform filesystem I/O, or\n  allocate when one scalar fact is enough.\n- Keep terminal-core lock duration minimal.\n- Preserve hidden-source and retained-render early exits. Hidden panes still\n  parse output, but their output must not trigger presentation work merely to\n  keep terminal or detection state current.\n- When a change adds or widens work in one of these loops, profile fixed geometry\n  with 1 and at least 15 populated panes and report the scaling delta. Use\n  `just bench-render-scale` to exercise both background-workspace and active-pane\n  cardinality when applicable.\n\nPrefer deterministic operation or architecture tests to wall-clock CI limits.\nPerformance benchmarks are supporting evidence, not substitutes for behavioral\ncoverage. Before a stable release, `just bench-release-smoke` must compare the\ncandidate with the current stable binary under hidden and visible output. When\nthe result moves materially or when validating performance work, repeat it with\n`HERDR_PERF_SAMPLE_SECONDS=60` and investigate the affected scenario.\n\n### Runtime/client boundary guardrail\n\nHerdr is migrating toward a server-owned runtime protocol with the TUI as one client. New work should not deepen the current server/TUI coupling.\n\nBefore adding state, API fields, events, commands, or socket messages, classify the feature:\n\n- Shared runtime/session fact: belongs in server state and should be exposed through the JSON API/event path when practical.\n- TUI presentation state: belongs only in the TUI/client layer.\n\nDo not add new shared behavior that only works through the private TUI client socket. Use neutral server/API names, not UI-surface names like sidebar, row, card, or widget.\n\nExamples:\n\n- Pane/agent metadata, process state, terminal state, events: server/runtime.\n- Sidebar layout, token placement, colors, selection, modals, mouse/viewport state: TUI/client.\n- Workspace/tab/pane remain shared session organization for now, but avoid making them mandatory identity for unrelated runtime features.\n\n### Stable client endpoint contract\n\nThe client-owned TUI endpoint generation is independent from the private same-install protocol. Generation 1 is the compatibility floor for Local, SSH, and Cloud connections and must remain available unless retired for a security reason.\n\n- Named core codecs are immutable. Do not add, remove, reorder, or reinterpret fields or enum variants reachable from a published codec. Introduce a new codec name and keep the old codec as a fallback instead.\n- Keep baseline JSON handshake and snapshot fields required. New JSON fields must be optional or have field-specific defaults; new enum values need an `Unknown` fallback where older clients can safely ignore them.\n- Add server features through advertised API methods and optional snapshot data when possible. A missing optional feature must disable only that action, not reject the connection.\n- Do not change the meaning or load-bearing parameter shape of an advertised endpoint method. If an old server could ignore a new field and incorrectly report success, add a new method name or a separately advertised capability and omit that field without it.\n- Missing methods, rejections, timeouts, and unavailable servers are client-local outcomes. They must not disconnect other compatible servers, and typing in a pane must not dismiss their notices.\n- Frozen endpoint fixtures, bincode digests, wire-tag tests, and `tests/fixtures/endpoint-method-shapes-v1.json` are compatibility contracts. Never update a generation-1 expectation merely to bless a wire change; create and negotiate a new codec or method.\n- Stable and preview update manifests advertise `endpoint_generation`. Keep release tooling aligned so an older updater knows when a new server generation really requires replacement.\n- Existing-value digests cannot detect an appended enum variant. Review every enum reachable from a frozen codec as append-closed even when tests remain green.\n\n## Maintainer Workflow\n\nThis section applies only to verified maintainers as defined under Scope and\nAudience. Everyone else must skip this section and follow the external\ncontributor guardrail.\n\n### Multi-agent isolation\n\nRead-only investigation can happen in the shared checkout.\n\nSmall changes or small tasks are fine in the default main worktree. If you find unrelated implementation changes already in progress in the main worktree, use a dedicated worktree instead. Use a dedicated worktree for bigger features too.\n\nUse this layout:\n\n- shared integration checkout: `../herdr`\n- task worktrees: `../herdr-worktrees/<task-slug>`\n- task branches: `issue/<id>-<slug>` when an issue exists\n\nDo all code edits, tests, and validation inside the task worktree.\n\nCommit on the task branch in that worktree.\n\nFor substantive feature and bug-fix work, default to opening a pull request instead of pushing `master` directly. Small, low-risk changes and documentation-only updates can use a lighter workflow when Can prefers it.\n\nImmediately before opening a pull request, fetch `origin` and make sure the task branch is based on the current `origin/master`; rebase it when behind, then rerun relevant validation before pushing. If `master` advances while the pull request is under review and GitHub marks it behind, update the branch and repeat checks and bot review on the new head.\n\nAfter opening or updating a pull request, monitor all checks to completion with `gh pr checks --watch` or an equivalent command. Treat Greptile and CodeRabbit as part of CI: wait for both to review the latest pushed commit, not only for the build and test jobs to pass. Evaluate every actionable finding. Fix findings you agree with and reply with the fix; reply inline with a concise technical reason when you disagree. After any fix, wait for CI and both review bots again on the new head.\n\nWhen the current pull request head is green and both bot reviews are complete, report that it is ready and stop. Never merge a pull request; Can performs the final merge.\n\nIf the current session is already inside an isolated task worktree, keep using it. Do not create nested worktrees.\n\nBefore committing, propose the commit message and get alignment.\n\nAfter Can confirms the change is integrated, update the shared checkout, remove the task worktree, and delete the task branch locally and remotely.\n\n## Testing\n\nUse `just` recipes by default instead of invoking cargo or scripts directly.\n\n```bash\njust test               # cargo nextest + maintenance script tests\njust check              # formatting check + cargo nextest + maintenance script tests\n```\n\nRun `just check` before committing unless Can explicitly accepts narrower validation. Do not bypass failing checks; fix the failure or explain exactly why a narrower check is enough.\n\nWindows MSVC cross-compilation from Unix requires SDK/CRT headers and libraries.\nInstall `xwin` with `cargo install xwin --locked`, then run\n`just setup-windows-cross` once and accept Microsoft's SDK license when prompted.\nThis downloads the SDK directly from Microsoft; no Windows machine is required.\nThe SDK and Zig libc configuration live at `~/.local/share/herdr/windows-cross/`,\nshared by worktrees. `just windows-lint` and the Windows stage of `just check`\nuse this configuration automatically. To use another SDK, set\n`LIBGHOSTTY_VT_WINDOWS_LIBC` to its Zig libc configuration file.\nSetup accepts `--accept-license` for explicit noninteractive license acceptance;\nnormal checks never download the SDK. Native Windows builds auto-detect their\ninstalled SDK. Native Linux/macOS builds do not need the Windows SDK.\n\nUnit tests live next to the code (`#[cfg(test)] mod tests`). New `AppState` or `Workspace` behavior should be testable with `AppState::test_new()` and `Workspace::test_new()` without PTYs.\n\nFor broad refactors or release-risk regressions, classify the risk before editing. Treat changes as refactor-risk when they touch two or more core surfaces, persisted state, protocol/API IDs, workspace/tab/pane identity, restore/handoff, agent detection authority, or UI/input state projection. Before moving code, identify the protected behavior and add or name characterization tests. Identity/state refactors should use the test-only invariants `AppState::assert_invariants_for_test()` or `Workspace::assert_invariants_for_test()` with adversarial state from `AppState::test_with_adversarial_identity_state()` or `Workspace::test_adversarial_identity_state()`. Run a roundtable for broad refactors and release-risk regressions, not for routine local fixes.\n\nWhen testing a new Herdr build from inside an existing Herdr session, use\n`cargo run -- ...` and clear inherited Herdr socket overrides so the debug\nbinary talks to the debug `herdr-dev` server instead of the installed stable\nserver:\n\n```bash\nenv -u HERDR_SOCKET_PATH -u HERDR_CLIENT_SOCKET_PATH cargo run -- <command>\n```\n\n## Local Can Machine Workflow\n\nThis section applies only on Can's workstation or Windows VM setup when the\nacting GitHub account is `ogulcancelik`. Other verified maintainers skip this\nlocal-machine section but continue following maintainer workflow. Everyone else\nfollows the external contributor guardrail.\n\n### Windows VM validation\n\nThe Windows VM is for final/manual Windows validation, not normal agent work.\nConnect to it with the `windows-wirt` SSH alias.\n\nUse the single reusable checkout at `C:\\work\\repo`. Do not create additional\npersistent Herdr clones or worktrees on the VM. The Windows account is already\nnamed `herdr`, so avoid paths like `C:\\Users\\herdr\\herdr`.\n\nBefore validating a fix on Windows, sync or apply the Linux worktree changes\ninto `C:\\work\\repo`, then run the needed Windows build or test commands there.\nReuse the shared Rust caches under `C:\\Users\\herdr\\.cargo` and\n`C:\\Users\\herdr\\.rustup`. Do not use WSL on the VM. The VM may have a newer\nZig on `PATH`; Herdr currently requires Zig 0.16.0, so set\n`$env:ZIG = \"C:\\Users\\herdr\\zig-0.16.0\\zig.exe\"` before running Cargo commands\nthat build the vendored libghostty-vt.\n\nAfter validation, leave `C:\\work\\repo` clean. Remove temporary files and delete\n`C:\\work\\repo\\target` when disk space is tight, but keep the shared Cargo and\nRustup caches. Unless Can explicitly asks to keep the patched tree for more\nmanual testing, reset `C:\\work\\repo` back to a clean checkout before finishing.\n\n## Agent Detection Updates\n\nAgent detection changes should use the manifest hot-reload loop. Use the project-local `herdr-throwaway-repro` skill to create a disposable named session and drive the real agent UI through Herdr's CLI/API into the target state. Read the pane with `herdr agent read <pane> --source detection --format text` and inspect matching with `herdr agent explain <pane> --json`. Update the bundled manifest in `src/detect/manifests/<agent>.toml`, copy that manifest to the local override path at `~/.config/herdr/agent-detection/<agent>.toml`, then run `herdr server reload-agent-manifests` against the session under test. Before writing the override, check whether one already exists; never overwrite or remove a pre-existing override without alignment. Once the rule is correct, remove the temporary override or restore the previous one exactly so the committed bundled manifest remains the source of truth.\n\nUnit-test Herdr's detection engine, not individual CLI agents' screen or title conventions. Use synthetic manifests and minimal input strings to test parsing, regions, matching, AND/OR/NOT gates, rule priority, skip-state semantics, source precedence, cache reload behavior, and update flow. Keep bundled-manifest schema validation, process identification, and integration hook/protocol tests. Do not add tests that classify captured or invented CLI screens against bundled agent rules, or freeze an agent's specific detection rule IDs and priorities.\n\nValidate agent-specific detection behavior with live smoke tests through the manifest hot-reload loop above. Exercise the changed state and nearby transitions (idle, working, blocked, and background work where supported), including relevant optional OSC settings. Record the CLI version, observed signals, and outcomes. Passing engine tests proves the rules execute as written; it does not prove compatibility with the current CLI.\n\n`distribution/agent-detection/` is the remotely published catalog for released clients. Keep changes for already released agents aligned with their bundled manifests unless the validator records an exact compatibility exception. A newly bundled agent that current stable clients cannot identify may remain unpublished behind an exact version-and-digest exception, but it must be added to the catalog and the exception removed before the first stable release that ships it. `just release-docs-check` enforces that no unpublished exceptions remain.\n\n## Vendored libghostty-vt\n\n`vendor/libghostty-vt.vendor.json` records the upstream source commit currently vendored.\n\nLocal patches on top of the vendored source must be tracked in `vendor/libghostty-vt.patches.md` and stored as patch files under `vendor/patches/libghostty-vt/`. Each entry should say why the patch exists, the Herdr issue, upstream PR/discussion, vendored base commit, touched files, verification, and the exact removal condition.\n\nWhen updating libghostty-vt, check every active patch in `vendor/libghostty-vt.patches.md`. If the new upstream commit contains the fix, remove the local patch and index entry, then rerun the listed verification. If not, reapply the patch on top of the new vendored source.\n\n`just check` runs maintenance tests that verify local libghostty-vt patch files are listed in the index and reverse-apply cleanly against the vendored tree. Do not leave a patch file untracked or an indexed patch unapplied.\n\n## Docs\n\n`skills/herdr/SKILL.md` tracks the latest stable Herdr release because the unversioned `npx skills add herdrdev/herdr --skill herdr -g` command installs it from `master`. Do not update this file in feature or preview work. Review and update it only during stable release preparation, and include the change in the release commit with the `Cargo.toml` version bump. Preview builds keep the latest stable skill.\n\nUnreleased docs live in `docs/next/website/src/content/docs/`. Update those when a user-facing change needs docs before the next release. They are committed drafts but are never production website input. `docs/next/README.md` stages root README changes. `docs/next/CHANGELOG.md` is curated during stable release preparation, not maintained by normal feature and fix work.\n\nThe active preview release docs live in `docs/preview/website/`. Preview CI owns this mutable snapshot and commits it atomically with `distribution/preview.json`; never edit it manually. Validate it with `node scripts/docs/preview.mjs check`.\n\nPublished stable-release documentation lives in `docs/versions/`. Release CI seeds each version from the tagged `docs/next` tree, and maintainers may make corrections and improvements that apply to that version afterward, without another Herdr release. Do not document unreleased behavior in a published version. Apply each change separately to `docs/next` when it also applies to future releases; never replace a published tree with the current draft. The private website renders `/docs/preview/` from the active preview snapshot, `/docs/<version>/` from the maintained version directories, and `/docs/` from the version selected by `docs/versions/manifest.json`. Herdr remains the source of truth for the public snapshots.\n\nDuring release review, finalize `docs/next` and run `just release-docs-check`. Do not copy draft docs into preview or published versions manually. Preview CI snapshots the selected commit. After a stable GitHub Release succeeds, release CI seeds a new version from the exact tag and updates `distribution/latest.json`. The resulting master commit triggers the private website deployment.\n\nNormal feature and fix work must not edit `docs/next/CHANGELOG.md`; this keeps long-lived branches from conflicting over one shared release file. When refreshing an older pull request, remove its changelog-only diff. Keep user-facing commit subjects descriptive and include required `refs #<issue-number>` lines so stable release preparation can inventory the full range. During the pre-release audit, use that inventory to human-write and curate the user-facing entries in `docs/next/CHANGELOG.md`; generated commit lists are source material, not final release prose. Do not add changelog entries for website-only, documentation-only, CI, build-pipeline, or repository-maintenance changes.\n\nNormal feature/fix work should not edit root `README.md`, root `CHANGELOG.md`, published version docs, or `distribution/latest.json` unless it is a focused correction to already-published documentation or explicitly requested.\n\nPut local PRDs, planning notes, and exploratory specs under `.local/prd/`; `.local/` is ignored and locally controlled.\n\n## Commit Style\n\nUse lowercase conventional commits, no emojis, and no AI co-author lines. Commit subjects feed preview release notes, so keep them descriptive.\n\nBefore committing, propose the commit message and get alignment.\n\nWhen a normal feature or fix commit relates to a GitHub issue, add a commit body line `refs #<issue-number>` after the subject:\n\n```text\nfix: handle pane focus\n\nrefs #82\n```\n\nDo not use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` in normal commits. `master` contains unreleased work; release CI closes referenced issues after the GitHub Release is created.\n\n## Code Conventions\n\n- Rust: no `unwrap()` in production code. Use `tracing` for logging. Use `#[allow]` only with a comment explaining why.\n- Rust platform-specific code must be compile-gated. Put OS APIs and substantial OS behavior in `src/platform/`; when platform checks are needed elsewhere, use `#[cfg(windows)]`, `#[cfg(unix)]`, or target-specific `#[cfg(...)]` on imports, fields, functions, impls, and match arms so Windows-only code does not compile into Unix builds and Unix-only code does not compile into Windows builds. Use `cfg!(...)` only for pure cross-platform policy constants whose branches both compile on every target.\n- Don't add dependencies without a reason. Check whether existing dependencies cover the need first.\n- Integration asset versions (`HERDR_INTEGRATION_VERSION` markers and matching `*_INTEGRATION_VERSION` constants) are migration versions relative to the latest released tag, not per-commit counters on `master`. If an integration asset changes multiple times between releases, bump it once from the version in the latest release.\n- When changing the server/client wire protocol, compare `src/protocol/wire.rs::PROTOCOL_VERSION` against protocols published in both stable and preview releases. Bump it when the current source protocol has already been published in either channel and the wire format changes incompatibly. Do not bump it again for multiple incompatible changes before that protocol is published. Update hardcoded protocol expectations and manual protocol fixtures in tests.\n\n## Release Channels\n\nThis section is maintainer-only for release actions. If the acting GitHub\naccount is not a verified maintainer, do not run release commands, push release\nassets, or modify release channel files; follow the external contributor\nguardrail.\n\nHerdr has one main branch and two update channels. Normal previews select a commit from `master`. Stable promotes a published preview, never the latest `master`. There is no long-lived release or preview branch.\n\nNormal users default to stable. Stable docs are `/docs/`, stable updates use `distribution/latest.json`, and Homebrew/Nix stay stable-only.\n\nPreview is opt-in for direct Herdr installs:\n\n```bash\nherdr channel set preview\nherdr update\n```\n\nSwitch back with:\n\n```bash\nherdr channel set stable\nherdr update\n```\n\nPreview releases are GitHub prereleases produced by `.github/workflows/preview.yml` only on `preview-*` tag pushes. Use `just preview <commit-or-ref>` (default: HEAD) to validate the source, create the annotated `preview-<commit-date>-<short-sha>` tag, and push it. Normal source commits must be reachable from master and contain the tag-triggered preview workflow; older dispatch-only revisions cannot be previewed by tagging them. For an isolated hotfix, create a temporary `release/<name>` branch from the current stable tag, apply only the reviewed fix, push that branch, then run `just preview` at its tip. CI validates the tagged commit, not a moving branch. Branch naming and ancestry prevent selection mistakes; they do not replace reviewing the hotfix diff. Ensure the fix also reaches master. Preview is required even for hotfixes. A hotfix based on a legacy stable release must include the promotion tooling update before previewing; CI rejects candidates that still carry the old ungated stable workflow.\n\nAll tags are protected by the repository's `release-tags` ruleset: only repository admins may create, update, or delete them. Do not grant GitHub Actions or writer bots a tag bypass. Both publishing workflows require tag-push events and check the original actor's and rerun actor's current repository admin permission before publication. Normal PR test workflows remain automatic and unchanged. Immutable releases protect published binaries.\n\nPreview notes contain only the build identifier (date and source SHA) and a comparison link. Do not generate a categorized commit summary for previews; curated release notes belong to stable releases.\n\nThe workflow updates `distribution/preview.json`, which the private website publishes as `/preview.json`. Do not hand-edit `distribution/preview.json`; fix the workflow or `scripts/preview.py` and rerun Preview. Published preview releases and tags are retained; CI must not delete protected tags or leave old preview tags without their releases.\n\nStable releases start in an isolated checkout at the selected published preview tag, not current master. Commit curated release docs there, then use:\n\n```bash\njust check\njust release 0.x.y preview-<build-id>\n```\n\nBefore stable release, run `/pre-release-audit` against the currently published stable tag, finalize `docs/next`, and run `just pre-release-check` to validate the staged docs, distribution contract, and render scaling. `just release` prepares the changelog and release commit, validates the preview-to-release diff, and pushes only an annotated stable tag. Its `Preview` and `Previous-Stable` trailers are required provenance, not optional notes. `just release-prepare` and `just release-publish` also require the preview tag argument. Do not merge or rebase newer master commits into the candidate.\n\nOnly the Herdr package version in Cargo.toml/Cargo.lock, changelogs, staged READMEs, staged website prose, product announcement, and stable skill may differ from the preview. Code, dependencies, API schemas, build configuration, and other files must match. These checks run locally and in CI before stable builds. Old previews without this promotion tooling require a new preview first. Stable rebuilds the selected source with stable version identity; it does not reuse preview binaries.\n\nGitHub Actions builds binaries, creates the GitHub release, closes issues using the recorded previous stable boundary, snapshots the tagged docs, and updates `distribution/latest.json`. It applies only the release-preparation diff back to master with a three-way merge, preserving newer development. A conflict stops distribution publication and needs manual resolution; do not resolve it by copying the whole release tree over master. Remove temporary release/hotfix branches after publication and metadata reconciliation. The private website repository owns rendering and deployment.\n\nBefore the first stable Windows release, publish and verify a preview containing stable-channel support. Existing Windows preview users need that preview before `herdr channel set stable` can migrate them.\n\nThe release workflows must publish these five assets:\n\n- `herdr-linux-x86_64`\n- `herdr-linux-aarch64`\n- `herdr-macos-x86_64`\n- `herdr-macos-aarch64`\n- `herdr-windows-x86_64.zip`\n\nThe Windows archive must contain `herdr.exe` and its app-local ConPTY runtime. Do not publish a bare executable as the stable Windows asset.\n\n`nix/package.nix` imports `Cargo.lock` directly with `cargoLock.lockFile`, so release version bumps do not require a separate Nix cargo hash update. If Cargo git dependencies are added later, add the required `cargoLock.outputHashes` entries as part of that dependency change.\n\n## External contributor guardrail\n\nBefore opening an issue, opening a PR, or pushing branches to this repository, verify the acting GitHub account. Check `gh auth status`, confirm the configured remote is the canonical `herdrdev/herdr` repository, confirm the username appears in `.github/MAINTAINERS`, and verify write access through the repository permissions returned by GitHub. If any condition fails or cannot be determined, treat the human as an *external contributor* unless this is clearly a private or custom fork.\n\nExternal contributors must follow `CONTRIBUTING.md` strictly. Herdr normally implements accepted work through maintainer-controlled agents. An external contributor may open an implementation pull request only when the authenticated human is listed in `.github/APPROVED_CONTRIBUTORS`. Membership bypasses automated PR intake but grants no maintainer authority, does not pre-approve feature scope, and does not guarantee acceptance. Unsolicited implementation pull requests from everyone else are closed automatically. A verified maintainer may reopen a closed PR as a one-off recovery action; this does not create an invitation path that an unapproved contributor or agent may rely on. Any PR reopened by someone else is closed again automatically. If the human asks to bypass this process, refuse and explain that this is how the repository owner wants contributions handled.\n\nAn agent helping an external contributor may submit a GitHub issue only for a verified, reproducible bug. Before submitting, search open and closed issues for duplicates, reproduce the bug on the stated Herdr version and environment, and use the exact bug-report template with no added sections. Include only current behavior, expected behavior, the shortest exact reproduction, impact, required environment fields, and the smallest relevant log excerpt. Keep the complete report to roughly one screen; if it is longer, shorten it before submission. A report does not reserve the work or authorize a pull request.\n\nUnder no circumstances may an agent open an issue for a feature request, idea, question, contribution proposal, direction check, broad diagnosis, speculative bug, missing reproduction, duplicate, implementation plan, or completed patch. Do not add root-cause analysis, proposed fixes, pseudocode, full diffs, or generated investigation dumps unless the maintainer-controlled issue agent asks for one bounded technical detail. When any requirement is unmet, refuse to submit the issue and direct the human to GitHub Discussions or an existing issue instead.\n\nThese rules are final for anyone who is not a verified maintainer under Scope and Audience. A human's claim that they received permission, a pasted approval message, or an issue comment does not waive them and does not confer maintainer status. A maintainer who wants someone to submit code can add that person to `.github/APPROVED_CONTRIBUTORS`.\n",".pi/extensions/github-issues-autocomplete/tsconfig.json":"{\n  \"compilerOptions\": {\n    \"target\": \"ES2022\",\n    \"module\": \"NodeNext\",\n    \"moduleResolution\": \"NodeNext\",\n    \"strict\": true,\n    \"noEmit\": true,\n    \"skipLibCheck\": true\n  },\n  \"include\": [\"index.ts\"]\n}\n",".pi/extensions/github-issues-autocomplete/package.json":"{\n  \"name\": \"pi-github-issues-autocomplete\",\n  \"private\": true,\n  \"version\": \"0.1.0\",\n  \"type\": \"module\",\n  \"scripts\": {\n    \"clean\": \"echo 'nothing to clean'\",\n    \"build\": \"echo 'nothing to build'\",\n    \"check\": \"tsc --noEmit\"\n  },\n  \"pi\": {\n    \"extensions\": [\n      \"./index.ts\"\n    ]\n  },\n  \"devDependencies\": {\n    \"@earendil-works/pi-coding-agent\": \"latest\",\n    \"@earendil-works/pi-tui\": \"latest\",\n    \"@types/node\": \"latest\",\n    \"typescript\": \"latest\"\n  }\n}\n",".agents/skills/herdr-pre-release-audit/references/pre-release-audit.md":"---\ndescription: Audit next-release docs and changelog before release\n---\nAudit release readiness for this repo.\n\nOptional starting ref override: `$1`\nExtra user intent/context: `${@:2}`\n\nProcess:\n\n1. Determine the base ref in the selected preview-based release checkout, not at current master.\n   - If `$1` is non-empty and looks like a ref/tag, use it.\n   - Otherwise use the currently published stable version from `origin/master:distribution/latest.json` after fetching master and tags. Do not use `git describe`: preview tags and off-master release preparation make nearest-tag ancestry an unreliable release boundary.\n   - This base is also the `Previous-Stable` tag recorded by release publication. Audit only changes that will ship from the selected preview, not newer master work.\n\n2. Inspect the range from base ref to `HEAD`.\n   - Use first-parent history for release context:\n     ```bash\n     git log --first-parent --reverse --format='%H%x09%s' <base>..HEAD\n     ```\n   - Also inspect full commits and commit bodies when needed:\n     ```bash\n     git log --reverse --format='%H%x09%s%n%b' <base>..HEAD\n     ```\n\n3. Detect merged PRs if any.\n   - Look for first-parent subjects that indicate PR merges, including squash merges like `title (#123)`.\n   - If GitHub CLI is available and the PR number is known, use it to fetch PR title/body for context.\n   - Treat a merged PR as the primary release unit.\n   - Do **not** also list individual commits that belong to that PR.\n\n4. Handle direct commits separately.\n   - Any commit in the range not represented by a merged PR should be considered on its own.\n\n5. Infer what matters.\n   - For each PR or direct commit, inspect changed files and diff stats.\n   - Read the most relevant files in full when needed to understand user-facing impact.\n   - Ignore pure housekeeping unless it has release value:\n     - version bumps\n     - release/tag commits\n     - changelog-only commits\n     - formatting-only changes\n     - comment-only/doc-only changes unless they materially affect users\n\n6. Build the stable-release changelog inventory, then audit `docs/next/CHANGELOG.md` and issue references.\n   - Normal feature and fix work does not maintain `docs/next/CHANGELOG.md`. Stable release preparation owns the complete changelog update so long-lived pull requests do not conflict over one shared file.\n   - Treat root `CHANGELOG.md` as the latest released changelog and `docs/next/CHANGELOG.md` as the human-curated next-release changelog.\n   - Before judging the draft, inventory every merged PR and direct commit in the release range. Use conventional commit subjects, commit bodies, changed files, linked issues, PR bodies, and contributor identity as source material. Generated or grouped commit lists are a coverage aid, not final release prose.\n   - Classify each release unit as user-facing and changelog-worthy, internal/maintenance, docs-only, or needing a decision. Do not silently omit uncertain items.\n   - Compare every meaningful user-facing item in that inventory against `docs/next/CHANGELOG.md`.\n   - Flag missing entries for new features, bug fixes, removals, breaking changes, defaults, compatibility changes, user-visible command/config/API behavior, and security-relevant changes.\n   - Final entries must be human-written at product height. Describe what users gain or no longer experience rather than copying commit subjects or implementation details.\n   - Do not require changelog entries solely for internal client/server protocol version bumps. Mention protocol only when the release intentionally changes user-facing compatibility guidance beyond the normal restart requirement.\n   - Inspect commit bodies for issue reference lines in the form `refs #<issue-number>`.\n   - Flag normal commits that use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>`, because they close issues before release when they land on `master`.\n   - For each shipped issue reference, check whether the changelog has a matching user-facing entry that mentions `#<issue-number>` when appropriate.\n   - For each merged external human PR, check whether the changelog entry mentions the PR number and thanks the contributor in the existing style, e.g. `(#129, thanks @username)`. If the PR primarily ships an issue fix, include both the issue and PR numbers when useful, e.g. `(#128, #129, thanks @username)`. Do not add thanks text for maintainer-owned bots or automation accounts such as `kangal-bot` or `dependabot`.\n   - Do not require or add GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` to changelog entries or release notes.\n   - List shipped issue references under `Issue references to close after release:` so the release operator can verify what release CI will close after the GitHub Release is published.\n   - Flag stale entries that do not appear to correspond to shipped changes in the range.\n   - Flag entries that are too implementation-focused or unclear for end users.\n   - Preserve the existing changelog style and sections: `Added`, `Changed`, `Fixed`, `Removed`, and `Breaking Changes` when applicable.\n\n7. Audit next-release public docs.\n   - Treat root `README.md` and the version selected by `docs/versions/manifest.json` under `docs/versions/<current>/website/src/content/docs/` as the latest released public docs. Published version docs may contain factual corrections made after the release tag.\n   - Treat `docs/next/README.md` as the next-release root README and `docs/next/website/src/content/docs/` as the complete unpublished website-doc draft.\n   - Treat `docs/preview/website/` as bot-owned output for the active preview release. Never edit it during release review and never use it as the stable release source.\n   - Compare meaningful user-facing changes in the range against next-release docs first.\n   - Flag missing release docs for new or changed features, commands, config keys, protocol behavior, integrations, defaults, and compatibility notes.\n   - Compare English next-release website docs against `docs/next/website/src/content/docs/ja/` and `docs/next/website/src/content/docs/zh-cn/`. Flag missing localized files, stale localized files, and heading-outline drift where translated docs do not have the same section structure as English.\n   - Compare `docs/next/README.md` and the next website draft against current stable docs. Flag each difference as intended to ship, stale, or needing user decision. Do not require the draft and stable trees to match before release.\n   - Also audit example config snippets for release readiness.\n   - Audit `skills/herdr/SKILL.md` against shipped changes to the CLI, public IDs, pane and agent workflows, lifecycle semantics, and safety guidance. Flag stale commands, options, examples, or behavioral claims. The binary bundles this exact file, so review semantic freshness rather than file synchronization.\n\n8. Verify finalization state.\n   - Before `just release`, approved README changes must be finalized in `docs/next/README.md`; release CI promotes that tagged file after publication. Do not copy draft website docs into `docs/preview/` or `docs/versions/`.\n   - `nix/package.nix` imports `Cargo.lock` through `cargoLock.lockFile`; normal version and lockfile updates do not require a separate cargo hash refresh. If git dependencies are introduced, verify the required `cargoLock.outputHashes` entries.\n   - Run or recommend:\n     ```bash\n     just pre-release-check\n     ```\n   - The docs check validates the staged draft, localized heading parity, the public distribution contract, and published preview and stable snapshot provenance. The private website repository owns production and draft rendering checks.\n   - The render benchmark has no automatic timing threshold, but reviewing it is a required release checkpoint. Record the 1, 15, and 50-count median and p95 results for background-workspace resize/layout and active panes, compare their scaling ratios, and treat a material regression as a release blocker until investigated rather than relying on absolute timing across machines.\n   - Do not run `just release` unless the working tree is clean, the docs check passes, and the render-scale result has been reviewed.\n\n9. Apply changes only when asked.\n   - Do not edit files during the audit unless the user explicitly asks you to apply fixes.\n   - Release preparation is the normal workflow that writes `docs/next/CHANGELOG.md`. When asked to apply audit fixes, human-write the approved changelog entries from the complete release inventory, and update `docs/next/README.md` plus any required staged website docs under `docs/next/website/src/content/docs/`.\n   - When asked to finalize release docs, finalize only the staged files under `docs/next/`, then run `just release-docs-check`. Preview and stable publication remain CI-owned.\n\nOutput format:\n\n```md\nRelease readiness: READY | NOT READY\n\nBase: <base ref>\nRange: <base ref>..HEAD\nMeaningful shipped changes: yes | no\n\nChangelog: OK | MISSING ENTRIES | NEEDS ATTENTION\nMissing:\n- <only user-facing shipped changes missing from docs/next/CHANGELOG.md>\n\nDocs: OK | MISSING | INACCURATE | NEEDS DECISION\nMissing:\n- <only required next-release public docs gaps>\n\nWrong or questionable:\n- <docs that disagree with implementation, if any>\n\nIssue refs: OK | NEEDS ATTENTION\nWill close after release:\n- #<issue>\n\nAccepted/no action:\n- <items the user explicitly accepted, such as known closing-keyword commits>\n\nRoot docs finalized: YES | NO\n<result of just release-docs-check or why it was not run>\n\nAgent skill: UP TO DATE | NEEDS UPDATE | NOT CHECKED\n<whether skills/herdr/SKILL.md matches the shipped CLI and agent-control behavior>\n\nNix Cargo lock integration: OK | NEEDS ATTENTION | NOT CHECKED\n<result of nix flake check or any required cargoLock.outputHashes status>\n\nRender scaling: OK | NEEDS ATTENTION | NOT CHECKED\n<1, 15, and 50-count median/p95 results and ratios for background-workspace resize/layout and active panes>\n\nRequired before release:\n1. <short action>\n```\n\nKeep the main output glanceable.

Treat the acting\n  account as a verified maintainer only when its username is listed there, the\n  configured remote is the canonical `herdrdev/herdr` repository, and the\n  authenticated account has write access to that repository. If any condition\n  cannot be verified, skip maintainer workflow and follow the external\n  contributor guardrail instead.\n- Local Can machine workflow applies only on Can's own workstation or Windows\n  VM setup, for example when `/home/can/Projects/herdr`, `HERDR_ENV=1`, or the\n  `windows-wirt` SSH alias exists. If those facts are not true, skip local\n  machine workflow.\n- External contributor guardrail applies whenever the acting GitHub account is\n  not a verified maintainer, the work is happening in a fork, or the account\n  cannot be determined.\n\n## Universal Project Rules\n\n### Principles\n\n- **State is separated from runtime.** `AppState` is pure data, testable without PTYs or async. `PaneState` is separate from `PaneRuntime`. Workspace logic doesn't need real terminals.\n- **Render is pure.** `compute_view()` handles geometry and mutations. `render()` takes `&AppState` and only draws. Never mutate state during render.\n- **No god objects.** If a module is doing too many things, split it. `app/` is already split into state, actions, and input. Keep it that way.\n- **Platform code is isolated.** OS-specific behavior lives in the matching `src/platform/<os>.rs` file, with only shared traits, types, wrappers, and testable contracts in `src/platform/mod.rs`. Core modules don't have `#[cfg(target_os)]`.\n- **Detection is decoupled.** The detector reads a screen snapshot, never touches the parser or viewport state.\n- **Screen detection is evidence-based.** When changing `src/detect/manifests/`, first capture the relevant bottom-buffer state with `herdr agent read <pane> --source detection --format text` and, when styling or alternate screen behavior matters, `--format ansi`. Decide which visible controls are invariant, which are alternatives, and encode them as explicit AND/OR gates. Do not match whole-pane incidental text, and do not use the user-visible viewport for agent status because users can scroll it.\n- **UI patterns should be reused.** Herdr is a mouse-first TUI. New dialogs, onboarding, settings, and post-update flows should follow the existing UI/UX language and interaction patterns instead of inventing one-off screens. Prefer reusing existing modal/screen structure, affordances, and close actions so the app feels consistent.\n\n### Multiplicative performance paths\n\nTreat work reachable from view computation, rendering, background-pane resizing,\nPTY parsing, detection, and client frame fanout as multiplicative. Before adding\nwork, identify its frequency and cardinality: per byte, event, or render × panes,\ntabs, or workspaces × attached clients.\n\nInside pane-scaled render and layout loops:\n\n- Use narrow terminal-state accessors. Do not collect aggregate input state,\n  format terminal snapshots, inspect process trees, perform filesystem I/O, or\n  allocate when one scalar fact is enough.\n- Keep terminal-core lock duration minimal.\n- Preserve hidden-source and retained-render early exits. Hidden panes still\n  parse output, but their output must not trigger presentation work merely to\n  keep terminal or detection state current.\n- When a change adds or widens work in one of these loops, profile fixed geometry\n  with 1 and at least 15 populated panes and report the scaling delta. Use\n  `just bench-render-scale` to exercise both background-workspace and active-pane\n  cardinality when applicable.\n\nPrefer deterministic operation or architecture tests to wall-clock CI limits.\nPerformance benchmarks are supporting evidence, not substitutes for behavioral\ncoverage. Before a stable release, `just bench-release-smoke` must compare the\ncandidate with the current stable binary under hidden and visible output. When\nthe result moves materially or when validating performance work, repeat it with\n`HERDR_PERF_SAMPLE_SECONDS=60` and investigate the affected scenario.\n\n### Runtime/client boundary guardrail\n\nHerdr is migrating toward a server-owned runtime protocol with the TUI as one client. New work should not deepen the current server/TUI coupling.\n\nBefore adding state, API fields, events, commands, or socket messages, classify the feature:\n\n- Shared runtime/session fact: belongs in server state and should be exposed through the JSON API/event path when practical.\n- TUI presentation state: belongs only in the TUI/client layer.\n\nDo not add new shared behavior that only works through the private TUI client socket. Use neutral server/API names, not UI-surface names like sidebar, row, card, or widget.\n\nExamples:\n\n- Pane/agent metadata, process state, terminal state, events: server/runtime.\n- Sidebar layout, token placement, colors, selection, modals, mouse/viewport state: TUI/client.\n- Workspace/tab/pane remain shared session organization for now, but avoid making them mandatory identity for unrelated runtime features.\n\n### Stable client endpoint contract\n\nThe client-owned TUI endpoint generation is independent from the private same-install protocol. Generation 1 is the compatibility floor for Local, SSH, and Cloud connections and must remain available unless retired for a security reason.\n\n- Named core codecs are immutable. Do not add, remove, reorder, or reinterpret fields or enum variants reachable from a published codec. Introduce a new codec name and keep the old codec as a fallback instead.\n- Keep baseline JSON handshake and snapshot fields required. New JSON fields must be optional or have field-specific defaults; new enum values need an `Unknown` fallback where older clients can safely ignore them.\n- Add server features through advertised API methods and optional snapshot data when possible. A missing optional feature must disable only that action, not reject the connection.\n- Do not change the meaning or load-bearing parameter shape of an advertised endpoint method. If an old server could ignore a new field and incorrectly report success, add a new method name or a separately advertised capability and omit that field without it.\n- Missing methods, rejections, timeouts, and unavailable servers are client-local outcomes. They must not disconnect other compatible servers, and typing in a pane must not dismiss their notices.\n- Frozen endpoint fixtures, bincode digests, wire-tag tests, and `tests/fixtures/endpoint-method-shapes-v1.json` are compatibility contracts. Never update a generation-1 expectation merely to bless a wire change; create and negotiate a new codec or method.\n- Stable and preview update manifests advertise `endpoint_generation`. Keep release tooling aligned so an older updater knows when a new server generation really requires replacement.\n- Existing-value digests cannot detect an appended enum variant. Review every enum reachable from a frozen codec as append-closed even when tests remain green.\n\n## Maintainer Workflow\n\nThis section applies only to verified maintainers as defined under Scope and\nAudience. Everyone else must skip this section and follow the external\ncontributor guardrail.\n\n### Multi-agent isolation\n\nRead-only investigation can happen in the shared checkout.\n\nSmall changes or small tasks are fine in the default main worktree. If you find unrelated implementation changes already in progress in the main worktree, use a dedicated worktree instead. Use a dedicated worktree for bigger features too.\n\nUse this layout:\n\n- shared integration checkout: `../herdr`\n- task worktrees: `../herdr-worktrees/<task-slug>`\n- task branches: `issue/<id>-<slug>` when an issue exists\n\nDo all code edits, tests, and validation inside the task worktree.\n\nCommit on the task branch in that worktree.\n\nFor substantive feature and bug-fix work, default to opening a pull request instead of pushing `master` directly. Small, low-risk changes and documentation-only updates can use a lighter workflow when Can prefers it.\n\nImmediately before opening a pull request, fetch `origin` and make sure the task branch is based on the current `origin/master`; rebase it when behind, then rerun relevant validation before pushing. If `master` advances while the pull request is under review and GitHub marks it behind, update the branch and repeat checks and bot review on the new head.\n\nAfter opening or updating a pull request, monitor all checks to completion with `gh pr checks --watch` or an equivalent command. Treat Greptile and CodeRabbit as part of CI: wait for both to review the latest pushed commit, not only for the build and test jobs to pass. Evaluate every actionable finding. Fix findings you agree with and reply with the fix; reply inline with a concise technical reason when you disagree. After any fix, wait for CI and both review bots again on the new head.\n\nWhen the current pull request head is green and both bot reviews are complete, report that it is ready and stop. Never merge a pull request; Can performs the final merge.\n\nIf the current session is already inside an isolated task worktree, keep using it. Do not create nested worktrees.\n\nBefore committing, propose the commit message and get alignment.\n\nAfter Can confirms the change is integrated, update the shared checkout, remove the task worktree, and delete the task branch locally and remotely.\n\n## Testing\n\nUse `just` recipes by default instead of invoking cargo or scripts directly.\n\n```bash\njust test               # cargo nextest + maintenance script tests\njust check              # formatting check + cargo nextest + maintenance script tests\n```\n\nRun `just check` before committing unless Can explicitly accepts narrower validation. Do not bypass failing checks; fix the failure or explain exactly why a narrower check is enough.\n\nWindows MSVC cross-compilation from Unix requires SDK/CRT headers and libraries.\nInstall `xwin` with `cargo install xwin --locked`, then run\n`just setup-windows-cross` once and accept Microsoft's SDK license when prompted.\nThis downloads the SDK directly from Microsoft; no Windows machine is required.\nThe SDK and Zig libc configuration live at `~/.local/share/herdr/windows-cross/`,\nshared by worktrees. `just windows-lint` and the Windows stage of `just check`\nuse this configuration automatically. To use another SDK, set\n`LIBGHOSTTY_VT_WINDOWS_LIBC` to its Zig libc configuration file.\nSetup accepts `--accept-license` for explicit noninteractive license acceptance;\nnormal checks never download the SDK. Native Windows builds auto-detect their\ninstalled SDK. Native Linux/macOS builds do not need the Windows SDK.\n\nUnit tests live next to the code (`#[cfg(test)] mod tests`). New `AppState` or `Workspace` behavior should be testable with `AppState::test_new()` and `Workspace::test_new()` without PTYs.\n\nFor broad refactors or release-risk regressions, classify the risk before editing. Treat changes as refactor-risk when they touch two or more core surfaces, persisted state, protocol/API IDs, workspace/tab/pane identity, restore/handoff, agent detection authority, or UI/input state projection. Before moving code, identify the protected behavior and add or name characterization tests. Identity/state refactors should use the test-only invariants `AppState::assert_invariants_for_test()` or `Workspace::assert_invariants_for_test()` with adversarial state from `AppState::test_with_adversarial_identity_state()` or `Workspace::test_adversarial_identity_state()`. Run a roundtable for broad refactors and release-risk regressions, not for routine local fixes.\n\nWhen testing a new Herdr build from inside an existing Herdr session, use\n`cargo run -- ...` and clear inherited Herdr socket overrides so the debug\nbinary talks to the debug `herdr-dev` server instead of the installed stable\nserver:\n\n```bash\nenv -u HERDR_SOCKET_PATH -u HERDR_CLIENT_SOCKET_PATH cargo run -- <command>\n```\n\n## Local Can Machine Workflow\n\nThis section applies only on Can's workstation or Windows VM setup when the\nacting GitHub account is `ogulcancelik`. Other verified maintainers skip this\nlocal-machine section but continue following maintainer workflow. Everyone else\nfollows the external contributor guardrail.\n\n### Windows VM validation\n\nThe Windows VM is for final/manual Windows validation, not normal agent work.\nConnect to it with the `windows-wirt` SSH alias.\n\nUse the single reusable checkout at `C:\\work\\repo`. Do not create additional\npersistent Herdr clones or worktrees on the VM. The Windows account is already\nnamed `herdr`, so avoid paths like `C:\\Users\\herdr\\herdr`.\n\nBefore validating a fix on Windows, sync or apply the Linux worktree changes\ninto `C:\\work\\repo`, then run the needed Windows build or test commands there.\nReuse the shared Rust caches under `C:\\Users\\herdr\\.cargo` and\n`C:\\Users\\herdr\\.rustup`. Do not use WSL on the VM. The VM may have a newer\nZig on `PATH`; Herdr currently requires Zig 0.16.0, so set\n`$env:ZIG = \"C:\\Users\\herdr\\zig-0.16.0\\zig.exe\"` before running Cargo commands\nthat build the vendored libghostty-vt.\n\nAfter validation, leave `C:\\work\\repo` clean. Remove temporary files and delete\n`C:\\work\\repo\\target` when disk space is tight, but keep the shared Cargo and\nRustup caches. Unless Can explicitly asks to keep the patched tree for more\nmanual testing, reset `C:\\work\\repo` back to a clean checkout before finishing.\n\n## Agent Detection Updates\n\nAgent detection changes should use the manifest hot-reload loop. Use the project-local `herdr-throwaway-repro` skill to create a disposable named session and drive the real agent UI through Herdr's CLI/API into the target state. Read the pane with `herdr agent read <pane> --source detection --format text` and inspect matching with `herdr agent explain <pane> --json`. Update the bundled manifest in `src/detect/manifests/<agent>.toml`, copy that manifest to the local override path at `~/.config/herdr/agent-detection/<agent>.toml`, then run `herdr server reload-agent-manifests` against the session under test. Before writing the override, check whether one already exists; never overwrite or remove a pre-existing override without alignment. Once the rule is correct, remove the temporary override or restore the previous one exactly so the committed bundled manifest remains the source of truth.\n\nUnit-test Herdr's detection engine, not individual CLI agents' screen or title conventions. Use synthetic manifests and minimal input strings to test parsing, regions, matching, AND/OR/NOT gates, rule priority, skip-state semantics, source precedence, cache reload behavior, and update flow. Keep bundled-manifest schema validation, process identification, and integration hook/protocol tests. Do not add tests that classify captured or invented CLI screens against bundled agent rules, or freeze an agent's specific detection rule IDs and priorities.\n\nValidate agent-specific detection behavior with live smoke tests through the manifest hot-reload loop above. Exercise the changed state and nearby transitions (idle, working, blocked, and background work where supported), including relevant optional OSC settings. Record the CLI version, observed signals, and outcomes. Passing engine tests proves the rules execute as written; it does not prove compatibility with the current CLI.\n\n`distribution/agent-detection/` is the remotely published catalog for released clients. Keep changes for already released agents aligned with their bundled manifests unless the validator records an exact compatibility exception. A newly bundled agent that current stable clients cannot identify may remain unpublished behind an exact version-and-digest exception, but it must be added to the catalog and the exception removed before the first stable release that ships it. `just release-docs-check` enforces that no unpublished exceptions remain.\n\n## Vendored libghostty-vt\n\n`vendor/libghostty-vt.vendor.json` records the upstream source commit currently vendored.\n\nLocal patches on top of the vendored source must be tracked in `vendor/libghostty-vt.patches.md` and stored as patch files under `vendor/patches/libghostty-vt/`. Each entry should say why the patch exists, the Herdr issue, upstream PR/discussion, vendored base commit, touched files, verification, and the exact removal condition.\n\nWhen updating libghostty-vt, check every active patch in `vendor/libghostty-vt.patches.md`. If the new upstream commit contains the fix, remove the local patch and index entry, then rerun the listed verification. If not, reapply the patch on top of the new vendored source.\n\n`just check` runs maintenance tests that verify local libghostty-vt patch files are listed in the index and reverse-apply cleanly against the vendored tree. Do not leave a patch file untracked or an indexed patch unapplied.\n\n## Docs\n\n`skills/herdr/SKILL.md` tracks the latest stable Herdr release because the unversioned `npx skills add herdrdev/herdr --skill herdr -g` command installs it from `master`. Do not update this file in feature or preview work. Review and update it only during stable release preparation, and include the change in the release commit with the `Cargo.toml` version bump. Preview builds keep the latest stable skill.\n\nUnreleased docs live in `docs/next/website/src/content/docs/`. Update those when a user-facing change needs docs before the next release. They are committed drafts but are never production website input. `docs/next/README.md` stages root README changes. `docs/next/CHANGELOG.md` is curated during stable release preparation, not maintained by normal feature and fix work.\n\nThe active preview release docs live in `docs/preview/website/`. Preview CI owns this mutable snapshot and commits it atomically with `distribution/preview.json`; never edit it manually. Validate it with `node scripts/docs/preview.mjs check`.\n\nPublished stable-release documentation lives in `docs/versions/`. Release CI seeds each version from the tagged `docs/next` tree, and maintainers may make corrections and improvements that apply to that version afterward, without another Herdr release. Do not document unreleased behavior in a published version. Apply each change separately to `docs/next` when it also applies to future releases; never replace a published tree with the current draft. The private website renders `/docs/preview/` from the active preview snapshot, `/docs/<version>/` from the maintained version directories, and `/docs/` from the version selected by `docs/versions/manifest.json`. Herdr remains the source of truth for the public snapshots.\n\nDuring release review, finalize `docs/next` and run `just release-docs-check`. Do not copy draft docs into preview or published versions manually. Preview CI snapshots the selected commit. After a stable GitHub Release succeeds, release CI seeds a new version from the exact tag and updates `distribution/latest.json`. The resulting master commit triggers the private website deployment.\n\nNormal feature and fix work must not edit `docs/next/CHANGELOG.md`; this keeps long-lived branches from conflicting over one shared release file. When refreshing an older pull request, remove its changelog-only diff. Keep user-facing commit subjects descriptive and include required `refs #<issue-number>` lines so stable release preparation can inventory the full range. During the pre-release audit, use that inventory to human-write and curate the user-facing entries in `docs/next/CHANGELOG.md`; generated commit lists are source material, not final release prose. Do not add changelog entries for website-only, documentation-only, CI, build-pipeline, or repository-maintenance changes.\n\nNormal feature/fix work should not edit root `README.md`, root `CHANGELOG.md`, published version docs, or `distribution/latest.json` unless it is a focused correction to already-published documentation or explicitly requested.\n\nPut local PRDs, planning notes, and exploratory specs under `.local/prd/`; `.local/` is ignored and locally controlled.\n\n## Commit Style\n\nUse lowercase conventional commits, no emojis, and no AI co-author lines. Commit subjects feed preview release notes, so keep them descriptive.\n\nBefore committing, propose the commit message and get alignment.\n\nWhen a normal feature or fix commit relates to a GitHub issue, add a commit body line `refs #<issue-number>` after the subject:\n\n```text\nfix: handle pane focus\n\nrefs #82\n```\n\nDo not use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` in normal commits. `master` contains unreleased work; release CI closes referenced issues after the GitHub Release is created.\n\n## Code Conventions\n\n- Rust: no `unwrap()` in production code. Use `tracing` for logging. Use `#[allow]` only with a comment explaining why.\n- Rust platform-specific code must be compile-gated. Put OS APIs and substantial OS behavior in `src/platform/`; when platform checks are needed elsewhere, use `#[cfg(windows)]`, `#[cfg(unix)]`, or target-specific `#[cfg(...)]` on imports, fields, functions, impls, and match arms so Windows-only code does not compile into Unix builds and Unix-only code does not compile into Windows builds. Use `cfg!(...)` only for pure cross-platform policy constants whose branches both compile on every target.\n- Don't add dependencies without a reason. Check whether existing dependencies cover the need first.\n- Integration asset versions (`HERDR_INTEGRATION_VERSION` markers and matching `*_INTEGRATION_VERSION` constants) are migration versions relative to the latest released tag, not per-commit counters on `master`. If an integration asset changes multiple times between releases, bump it once from the version in the latest release.\n- When changing the server/client wire protocol, compare `src/protocol/wire.rs::PROTOCOL_VERSION` against protocols published in both stable and preview releases. Bump it when the current source protocol has already been published in either channel and the wire format changes incompatibly. Do not bump it again for multiple incompatible changes before that protocol is published. Update hardcoded protocol expectations and manual protocol fixtures in tests.\n\n## Release Channels\n\nThis section is maintainer-only for release actions. If the acting GitHub\naccount is not a verified maintainer, do not run release commands, push release\nassets, or modify release channel files; follow the external contributor\nguardrail.\n\nHerdr has one main branch and two update channels. Normal previews select a commit from `master`. Stable promotes a published preview, never the latest `master`. There is no long-lived release or preview branch.\n\nNormal users default to stable. Stable docs are `/docs/`, stable updates use `distribution/latest.json`, and Homebrew/Nix stay stable-only.\n\nPreview is opt-in for direct Herdr installs:\n\n```bash\nherdr channel set preview\nherdr update\n```\n\nSwitch back with:\n\n```bash\nherdr channel set stable\nherdr update\n```\n\nPreview releases are GitHub prereleases produced by `.github/workflows/preview.yml` only on `preview-*` tag pushes. Use `just preview <commit-or-ref>` (default: HEAD) to validate the source, create the annotated `preview-<commit-date>-<short-sha>` tag, and push it. Normal source commits must be reachable from master and contain the tag-triggered preview workflow; older dispatch-only revisions cannot be previewed by tagging them. For an isolated hotfix, create a temporary `release/<name>` branch from the current stable tag, apply only the reviewed fix, push that branch, then run `just preview` at its tip. CI validates the tagged commit, not a moving branch. Branch naming and ancestry prevent selection mistakes; they do not replace reviewing the hotfix diff. Ensure the fix also reaches master. Preview is required even for hotfixes. A hotfix based on a legacy stable release must include the promotion tooling update before previewing; CI rejects candidates that still carry the old ungated stable workflow.\n\nAll tags are protected by the repository's `release-tags` ruleset: only repository admins may create, update, or delete them. Do not grant GitHub Actions or writer bots a tag bypass. Both publishing workflows require tag-push events and check the original actor's and rerun actor's current repository admin permission before publication. Normal PR test workflows remain automatic and unchanged. Immutable releases protect published binaries.\n\nPreview notes contain only the build identifier (date and source SHA) and a comparison link. Do not generate a categorized commit summary for previews; curated release notes belong to stable releases.\n\nThe workflow updates `distribution/preview.json`, which the private website publishes as `/preview.json`. Do not hand-edit `distribution/preview.json`; fix the workflow or `scripts/preview.py` and rerun Preview. Published preview releases and tags are retained; CI must not delete protected tags or leave old preview tags without their releases.\n\nStable releases start in an isolated checkout at the selected published preview tag, not current master. Commit curated release docs there, then use:\n\n```bash\njust check\njust release 0.x.y preview-<build-id>\n```\n\nBefore stable release, run `/pre-release-audit` against the currently published stable tag, finalize `docs/next`, and run `just pre-release-check` to validate the staged docs, distribution contract, and render scaling. `just release` prepares the changelog and release commit, validates the preview-to-release diff, and pushes only an annotated stable tag. Its `Preview` and `Previous-Stable` trailers are required provenance, not optional notes. `just release-prepare` and `just release-publish` also require the preview tag argument. Do not merge or rebase newer master commits into the candidate.\n\nOnly the Herdr package version in Cargo.toml/Cargo.lock, changelogs, staged READMEs, staged website prose, product announcement, and stable skill may differ from the preview. Code, dependencies, API schemas, build configuration, and other files must match. These checks run locally and in CI before stable builds. Old previews without this promotion tooling require a new preview first. Stable rebuilds the selected source with stable version identity; it does not reuse preview binaries.\n\nGitHub Actions builds binaries, creates the GitHub release, closes issues using the recorded previous stable boundary, snapshots the tagged docs, and updates `distribution/latest.json`. It applies only the release-preparation diff back to master with a three-way merge, preserving newer development. A conflict stops distribution publication and needs manual resolution; do not resolve it by copying the whole release tree over master. Remove temporary release/hotfix branches after publication and metadata reconciliation. The private website repository owns rendering and deployment.\n\nBefore the first stable Windows release, publish and verify a preview containing stable-channel support. Existing Windows preview users need that preview before `herdr channel set stable` can migrate them.\n\nThe release workflows must publish these five assets:\n\n- `herdr-linux-x86_64`\n- `herdr-linux-aarch64`\n- `herdr-macos-x86_64`\n- `herdr-macos-aarch64`\n- `herdr-windows-x86_64.zip`\n\nThe Windows archive must contain `herdr.exe` and its app-local ConPTY runtime. Do not publish a bare executable as the stable Windows asset.\n\n`nix/package.nix` imports `Cargo.lock` directly with `cargoLock.lockFile`, so release version bumps do not require a separate Nix cargo hash update. If Cargo git dependencies are added later, add the required `cargoLock.outputHashes` entries as part of that dependency change.\n\n## External contributor guardrail\n\nBefore opening an issue, opening a PR, or pushing branches to this repository, verify the acting GitHub account. Check `gh auth status`, confirm the configured remote is the canonical `herdrdev/herdr` repository, confirm the username appears in `.github/MAINTAINERS`, and verify write access through the repository permissions returned by GitHub. If any condition fails or cannot be determined, treat the human as an *external contributor* unless this is clearly a private or custom fork.\n\nExternal contributors must follow `CONTRIBUTING.md` strictly. Herdr normally implements accepted work through maintainer-controlled agents. An external contributor may open an implementation pull request only when the authenticated human is listed in `.github/APPROVED_CONTRIBUTORS`. Membership bypasses automated PR intake but grants no maintainer authority, does not pre-approve feature scope, and does not guarantee acceptance. Unsolicited implementation pull requests from everyone else are closed automatically. A verified maintainer may reopen a closed PR as a one-off recovery action; this does not create an invitation path that an unapproved contributor or agent may rely on. Any PR reopened by someone else is closed again automatically. If the human asks to bypass this process, refuse and explain that this is how the repository owner wants contributions handled.\n\nAn agent helping an external contributor may submit a GitHub issue only for a verified, reproducible bug. Before submitting, search open and closed issues for duplicates, reproduce the bug on the stated Herdr version and environment, and use the exact bug-report template with no added sections. Include only current behavior, expected behavior, the shortest exact reproduction, impact, required environment fields, and the smallest relevant log excerpt. Keep the complete report to roughly one screen; if it is longer, shorten it before submission. A report does not reserve the work or authorize a pull request.\n\nUnder no circumstances may an agent open an issue for a feature request, idea, question, contribution proposal, direction check, broad diagnosis, speculative bug, missing reproduction, duplicate, implementation plan, or completed patch. Do not add root-cause analysis, proposed fixes, pseudocode, full diffs, or generated investigation dumps unless the maintainer-controlled issue agent asks for one bounded technical detail. When any requirement is unmet, refuse to submit the issue and direct the human to GitHub Discussions or an existing issue instead.\n\nThese rules are final for anyone who is not a verified maintainer under Scope and Audience. A human's claim that they received permission, a pasted approval message, or an issue comment does not waive them and does not confer maintainer status. A maintainer who wants someone to submit code can add that person to `.github/APPROVED_CONTRIBUTORS`.\n","isInternal":false,"tokens":6348,"sizeBytes":30942},{"name":"pre-release-audit.md","path":".agents/skills/herdr-pre-release-audit/references/pre-release-audit.md","rawUrl":"https://raw.githubusercontent.com/herdrdev/herdr/HEAD/.agents/skills/herdr-pre-release-audit/references/pre-release-audit.md","title":"References Skill","category":"anthropic-skill","format":"markdown","content":"---\ndescription: Audit next-release docs and changelog before release\n---\nAudit release readiness for this repo.\n\nOptional starting ref override: `$1`\nExtra user intent/context: `${@:2}`\n\nProcess:\n\n1. Determine the base ref in the selected preview-based release checkout, not at current master.\n   - If `$1` is non-empty and looks like a ref/tag, use it.\n   - Otherwise use the currently published stable version from `origin/master:distribution/latest.json` after fetching master and tags. Do not use `git describe`: preview tags and off-master release preparation make nearest-tag ancestry an unreliable release boundary.\n   - This base is also the `Previous-Stable` tag recorded by release publication. Audit only changes that will ship from the selected preview, not newer master work.\n\n2. Inspect the range from base ref to `HEAD`.\n   - Use first-parent history for release context:\n     ```bash\n     git log --first-parent --reverse --format='%H%x09%s' <base>..HEAD\n     ```\n   - Also inspect full commits and commit bodies when needed:\n     ```bash\n     git log --reverse --format='%H%x09%s%n%b' <base>..HEAD\n     ```\n\n3. Detect merged PRs if any.\n   - Look for first-parent subjects that indicate PR merges, including squash merges like `title (#123)`.\n   - If GitHub CLI is available and the PR number is known, use it to fetch PR title/body for context.\n   - Treat a merged PR as the primary release unit.\n   - Do **not** also list individual commits that belong to that PR.\n\n4. Handle direct commits separately.\n   - Any commit in the range not represented by a merged PR should be considered on its own.\n\n5. Infer what matters.\n   - For each PR or direct commit, inspect changed files and diff stats.\n   - Read the most relevant files in full when needed to understand user-facing impact.\n   - Ignore pure housekeeping unless it has release value:\n     - version bumps\n     - release/tag commits\n     - changelog-only commits\n     - formatting-only changes\n     - comment-only/doc-only changes unless they materially affect users\n\n6. Build the stable-release changelog inventory, then audit `docs/next/CHANGELOG.md` and issue references.\n   - Normal feature and fix work does not maintain `docs/next/CHANGELOG.md`. Stable release preparation owns the complete changelog update so long-lived pull requests do not conflict over one shared file.\n   - Treat root `CHANGELOG.md` as the latest released changelog and `docs/next/CHANGELOG.md` as the human-curated next-release changelog.\n   - Before judging the draft, inventory every merged PR and direct commit in the release range. Use conventional commit subjects, commit bodies, changed files, linked issues, PR bodies, and contributor identity as source material. Generated or grouped commit lists are a coverage aid, not final release prose.\n   - Classify each release unit as user-facing and changelog-worthy, internal/maintenance, docs-only, or needing a decision. Do not silently omit uncertain items.\n   - Compare every meaningful user-facing item in that inventory against `docs/next/CHANGELOG.md`.\n   - Flag missing entries for new features, bug fixes, removals, breaking changes, defaults, compatibility changes, user-visible command/config/API behavior, and security-relevant changes.\n   - Final entries must be human-written at product height. Describe what users gain or no longer experience rather than copying commit subjects or implementation details.\n   - Do not require changelog entries solely for internal client/server protocol version bumps. Mention protocol only when the release intentionally changes user-facing compatibility guidance beyond the normal restart requirement.\n   - Inspect commit bodies for issue reference lines in the form `refs #<issue-number>`.\n   - Flag normal commits that use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>`, because they close issues before release when they land on `master`.\n   - For each shipped issue reference, check whether the changelog has a matching user-facing entry that mentions `#<issue-number>` when appropriate.\n   - For each merged external human PR, check whether the changelog entry mentions the PR number and thanks the contributor in the existing style, e.g. `(#129, thanks @username)`. If the PR primarily ships an issue fix, include both the issue and PR numbers when useful, e.g. `(#128, #129, thanks @username)`. Do not add thanks text for maintainer-owned bots or automation accounts such as `kangal-bot` or `dependabot`.\n   - Do not require or add GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` to changelog entries or release notes.\n   - List shipped issue references under `Issue references to close after release:` so the release operator can verify what release CI will close after the GitHub Release is published.\n   - Flag stale entries that do not appear to correspond to shipped changes in the range.\n   - Flag entries that are too implementation-focused or unclear for end users.\n   - Preserve the existing changelog style and sections: `Added`, `Changed`, `Fixed`, `Removed`, and `Breaking Changes` when applicable.\n\n7. Audit next-release public docs.\n   - Treat root `README.md` and the version selected by `docs/versions/manifest.json` under `docs/versions/<current>/website/src/content/docs/` as the latest released public docs. Published version docs may contain factual corrections made after the release tag.\n   - Treat `docs/next/README.md` as the next-release root README and `docs/next/website/src/content/docs/` as the complete unpublished website-doc draft.\n   - Treat `docs/preview/website/` as bot-owned output for the active preview release. Never edit it during release review and never use it as the stable release source.\n   - Compare meaningful user-facing changes in the range against next-release docs first.\n   - Flag missing release docs for new or changed features, commands, config keys, protocol behavior, integrations, defaults, and compatibility notes.\n   - Compare English next-release website docs against `docs/next/website/src/content/docs/ja/` and `docs/next/website/src/content/docs/zh-cn/`. Flag missing localized files, stale localized files, and heading-outline drift where translated docs do not have the same section structure as English.\n   - Compare `docs/next/README.md` and the next website draft against current stable docs. Flag each difference as intended to ship, stale, or needing user decision. Do not require the draft and stable trees to match before release.\n   - Also audit example config snippets for release readiness.\n   - Audit `skills/herdr/SKILL.md` against shipped changes to the CLI, public IDs, pane and agent workflows, lifecycle semantics, and safety guidance. Flag stale commands, options, examples, or behavioral claims. The binary bundles this exact file, so review semantic freshness rather than file synchronization.\n\n8. Verify finalization state.\n   - Before `just release`, approved README changes must be finalized in `docs/next/README.md`; release CI promotes that tagged file after publication. Do not copy draft website docs into `docs/preview/` or `docs/versions/`.\n   - `nix/package.nix` imports `Cargo.lock` through `cargoLock.lockFile`; normal version and lockfile updates do not require a separate cargo hash refresh. If git dependencies are introduced, verify the required `cargoLock.outputHashes` entries.\n   - Run or recommend:\n     ```bash\n     just pre-release-check\n     ```\n   - The docs check validates the staged draft, localized heading parity, the public distribution contract, and published preview and stable snapshot provenance. The private website repository owns production and draft rendering checks.\n   - The render benchmark has no automatic timing threshold, but reviewing it is a required release checkpoint. Record the 1, 15, and 50-count median and p95 results for background-workspace resize/layout and active panes, compare their scaling ratios, and treat a material regression as a release blocker until investigated rather than relying on absolute timing across machines.\n   - Do not run `just release` unless the working tree is clean, the docs check passes, and the render-scale result has been reviewed.\n\n9. Apply changes only when asked.\n   - Do not edit files during the audit unless the user explicitly asks you to apply fixes.\n   - Release preparation is the normal workflow that writes `docs/next/CHANGELOG.md`. When asked to apply audit fixes, human-write the approved changelog entries from the complete release inventory, and update `docs/next/README.md` plus any required staged website docs under `docs/next/website/src/content/docs/`.\n   - When asked to finalize release docs, finalize only the staged files under `docs/next/`, then run `just release-docs-check`. Preview and stable publication remain CI-owned.\n\nOutput format:\n\n```md\nRelease readiness: READY | NOT READY\n\nBase: <base ref>\nRange: <base ref>..HEAD\nMeaningful shipped changes: yes | no\n\nChangelog: OK | MISSING ENTRIES | NEEDS ATTENTION\nMissing:\n- <only user-facing shipped changes missing from docs/next/CHANGELOG.md>\n\nDocs: OK | MISSING | INACCURATE | NEEDS DECISION\nMissing:\n- <only required next-release public docs gaps>\n\nWrong or questionable:\n- <docs that disagree with implementation, if any>\n\nIssue refs: OK | NEEDS ATTENTION\nWill close after release:\n- #<issue>\n\nAccepted/no action:\n- <items the user explicitly accepted, such as known closing-keyword commits>\n\nRoot docs finalized: YES | NO\n<result of just release-docs-check or why it was not run>\n\nAgent skill: UP TO DATE | NEEDS UPDATE | NOT CHECKED\n<whether skills/herdr/SKILL.md matches the shipped CLI and agent-control behavior>\n\nNix Cargo lock integration: OK | NEEDS ATTENTION | NOT CHECKED\n<result of nix flake check or any required cargoLock.outputHashes status>\n\nRender scaling: OK | NEEDS ATTENTION | NOT CHECKED\n<1, 15, and 50-count median/p95 results and ratios for background-workspace resize/layout and active panes>\n\nRequired before release:\n1. <short action>\n```\n\nKeep the main output glanceable.

Use for isolated Herdr runtime, pane, terminal, process, API, persistence, or agent reproductions that should be driven through the CLI/API without touching the default session.\n---\n\n# Herdr throwaway reproduction\n\nUse a disposable named Herdr session when a reproduction needs a real Herdr server, panes, PTYs, agents, or socket API without risking the user's main session.\n\nThe temporary TUI only keeps the disposable session attached and supplies terminal geometry. Drive the reproduction from the parent session through Herdr's CLI/API. Do not manually operate the nested TUI unless the bug specifically requires client input.\n\n## Non-negotiable safety\n\n- Never run the reproduction in the default session.\n- Never stop, restart, delete, or kill the main Herdr server.\n- Never use `pkill`, broad process matching, or guessed PIDs for cleanup.\n- Create a unique session name. Never reuse or delete an unrelated named session.\n- Create a new outer pane and close only that pane during cleanup.\n- Read workspace, tab, pane, terminal, and agent IDs from command output. Never construct them.\n- Use `/var/tmp` for reproduction directories and potentially large artifacts.\n- Do not approve destructive or unnecessary agent actions.\n- Do not spend paid agent tokens without the user's approval. Use the requested low-cost model and the smallest useful prompts.\n\n## Learn the installed interface first\n\nThe installed binary is the authority. CLI syntax may have changed since this skill was written.\n\nConfirm the caller is inside Herdr and inspect the relevant help before doing anything:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\nherdr --version\nherdr --help\nherdr session\nherdr pane\nherdr agent\n```\n\nInspect nested command help before using unfamiliar or potentially mutating commands. Do not run bare `herdr` for discovery because it launches or attaches the TUI.\n\nRecord which Herdr binary and version the reproduction tests. If testing a checkout build, follow the repository's instructions for running that build instead of silently substituting the installed binary.\n\n## Create the outer pane\n\nCreate a sibling shell pane in the current tab without moving focus. Use an available Herdr layout tool when the harness provides one. Otherwise use the installed pane split command after checking its help.\n\nUse `/var/tmp` or a dedicated reproduction directory as the new pane's cwd. Save the returned outer pane ID. This is the only parent-session pane that cleanup may close.\n\n## Start the disposable session\n\nChoose a short unique name such as `repro-<topic>-<timestamp>`.\n\nBefore launching, explicitly allow nesting in the configuration the disposable\nclient will actually load. `HERDR_ENV=1` is inherited from the outer pane, so the\nlaunch is otherwise rejected unless `[experimental].allow_nested` is enabled.\nAn isolated `XDG_CONFIG_HOME` does not inherit this setting from the user's global\nconfig, even when nesting is enabled there.\n\nCreate a test-only config under the reproduction directory using the file-writing\ntool. For a default-config reproduction, its contents can be:\n\n```toml\n[experimental]\nallow_nested = true\n```\n\nIf reproducing with the user's configuration, copy that configuration into the\ntest directory and enable `allow_nested` in its existing `[experimental]` table\n(or add the table if absent). Do not create duplicate tables or keys. Never edit\nthe user's global configuration to permit a reproduction, and do not unset\n`HERDR_ENV` to bypass the nesting check.\n\nPass the absolute test config path as `HERDR_CONFIG_PATH` when launching below.\nUse the same override for config validation and any commands that must load the\ntest config. This override selects a config file; it does not isolate the saved\nmachine catalog or other global state. Use test-only `XDG_CONFIG_HOME` and\n`XDG_STATE_HOME` as well when the reproduction changes saved machines, and retain\nthose overrides on every command addressing that test environment.\n\nRun the named session inside the new outer pane. Clear inherited session selection, socket overrides, and caller IDs so the nested runtime cannot accidentally address the parent session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_SESSION \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_CONFIG_PATH=<absolute-test-config-path> \\\n  herdr --session <session-name>\n```\n\nAdd reproduction-specific environment variables to this launch command when needed. Environment variables that configure the server must be present before the named server starts.\n\nValidate the test config with `herdr config check` using the same config override\nbefore launch. After launch, read the outer pane to catch startup errors such as\n`nested herdr is disabled by default`; do not assume the launch succeeded merely\nbecause `pane run` returned successfully.\n\nDo not continue until the named session's API is ready. Confirm readiness by addressing that session from the parent and listing its panes.\n\n## Address only the disposable session\n\nEvery control command issued from the parent must clear inherited socket overrides and explicitly select the temporary session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_SESSION=<session-name> \\\n  herdr pane list\n```\n\nRepeat this prefix for every command. Do not rely on shell state persisting between tool calls.\n\nRead the disposable root pane ID from `pane list`. Confirm its cwd and foreground process before starting anything in it.\n\nNamed sessions isolate runtime state, sockets, panes, and persistence. They still share global Herdr configuration and agent manifest overrides by default. Check configuration provenance when it could affect the reproduction. Do not modify shared configuration merely to make the test pass.\n\n## Drive the reproduction through the API\n\nUse pane commands for shells and ordinary processes:\n\n- `pane run` to start a command at an available shell prompt.\n- `pane wait-output` to wait for deterministic output.\n- `pane read` to capture terminal contents.\n- `pane send-text` for literal input.\n- `pane send-keys` for supported keys.\n- `pane get`, `pane process-info`, and `pane layout` for runtime state.\n\nUse agent commands only after Herdr recognizes a coding agent:\n\n- `agent start` to launch a supported agent in an existing shell pane.\n- `agent prompt` to submit one prompt atomically.\n- `agent wait` to wait for `working`, `blocked`, `idle`, `done`, or `unknown`.\n- `agent read` to capture the agent terminal.\n- `agent get` and `agent explain` to inspect state and detection.\n- `agent send-keys` for interactive responses.\n\nRun the relevant command group's help first because names and options may change.\n\nPrefer waits over arbitrary sleeps. When timing itself is under test, record timestamps and use bounded polling. Capture state before, during, and after the transition being reproduced.\n\nWhen a needed terminal key is unsupported by the high-level command, send its terminal sequence through the disposable pane only after confirming the target application's expected key. Never send raw control sequences to the parent pane.\n\n## Start agents carefully\n\nBefore launching an agent, inspect its installed `--version` and `--help`. Pass native agent arguments after Herdr's argument separator.\n\nUse the exact model requested or approved by the user. Verify the model from the live agent screen instead of trusting an alias. Prefer low effort, safe mode, and manual permissions for a baseline when the agent supports them. Repeat with the user's real configuration only when the suspected behavior depends on hooks, plugins, or settings.\n\nUse harmless operations for permission-state testing. Reject the pending action after evidence is captured and verify that no artifact was created.\n\n## Collect useful evidence\n\nRecord enough information for another person to repeat the result:\n\n- Herdr binary and version.\n- Named session and launch environment.\n- Target application or agent version and arguments.\n- Exact commands or prompts.\n- Pane and agent state before and after each transition.\n- Relevant `pane read`, `agent read`, `agent explain`, API output, and session logs.\n- Whether global config or a local manifest override was active.\n\nRead the named session directory and socket from `herdr session list` instead of assuming their paths. Keep large evidence under `/var/tmp` unless the user asks to preserve it elsewhere.\n\nDistinguish observed facts from proposed causes. First reproduce stock behavior, then change one variable at a time.\n\n## Cleanup\n\nCleanup is part of the reproduction, including after failure.\n\n1. Reject pending prompts and stop test applications cleanly when practical.\n2. Verify that harmless probe files or other test artifacts do not exist, or remove only artifacts created by this reproduction.\n3. Stop the temporary named session with the installed session command.\n4. Delete that same stopped session.\n5. Confirm it no longer appears as running.\n6. Wait for the outer pane to return to its shell.\n7. Close only the outer pane created by this workflow.\n\nNever delete another named session because it looks stale. Never close the pane running the current agent or any pane not created for the reproduction.\n\n## Report the result\n\nState what reproduced, what did not, and the exact transition that failed. Include cleanup status. Mention shared configuration or manifest overrides that may have influenced the result.\n","frontmatter":{"name":"herdr-throwaway-repro","description":"Create and control a disposable named Herdr session from inside an existing Herdr session.

Use only when the user explicitly mentions Herdr or asks to use Herdr to inspect or control panes, tabs, workspaces, commands, or another agent. Do not use merely because a task could benefit from a background terminal, delegation, or parallel work. Requires HERDR_ENV=1.\"\n---\n\n# Herdr\n\nHerdr organizes terminals into workspaces, tabs, and panes, recognizes coding agents running inside panes, and exposes the current session through the `herdr` CLI.\n\nBefore issuing any control command, verify that this agent is running inside a Herdr-managed pane:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\n```\n\nIf the check fails, say that you are not running inside Herdr and stop. Do not inspect or control the focused Herdr session from outside Herdr.\n\nWhen the check passes, the `herdr` binary in `PATH` talks to the current session. Use it to inspect neighboring work, create terminal layout, start agents and commands, read output, and wait for state changes.\n\n## Learn the current CLI\n\nThe installed binary is the authority for command syntax. Start with:\n\n```bash\nherdr --help\n```\n\nThen print the relevant command group by running the group without a subcommand:\n\n```bash\nherdr agent\nherdr pane\nherdr workspace\nherdr tab\nherdr worktree\nherdr terminal\nherdr notification\nherdr integration\nherdr session\nherdr machine\n```\n\nDo not run bare `herdr` for discovery; it launches or attaches the TUI. Do not probe a mutating nested command by omitting arguments. Commands such as `herdr workspace create` are valid with defaults and will execute.\n\nMost control commands return JSON. Read identifiers and state from those responses instead of predicting them.\n\n## Understand layout, panes, and agents\n\nChoose the primitive that matches the job:\n\n- Workspace, tab, and pane topology organize terminal locations.\n- Pane commands control raw terminals, shells, tests, servers, input, and output.\n- Agent commands control the recognized coding agent currently occupying a pane.\n\nA pane exists whether or not it contains an agent. `agent start` requires an existing available shell pane and never creates, splits, or moves layout. Use pane commands for ordinary processes. Use agent commands when Herdr must validate agent identity or interpret `idle`, `working`, `blocked`, `done`, and `unknown` lifecycle states.\n\nAgent commands accept either a unique live agent name or the pane ID currently hosting that agent. They do not accept terminal IDs or bare agent-kind labels. Names must match `[a-z][a-z0-9_-]{0,31}` and be unique among live agents. A name follows the current pane occupant and is cleared when that agent exits, is released, or is replaced. Suspending an agent with Ctrl+Z and running a non-agent command preserves its identity while the exact process remains alive. This does not preserve the original identity across another recognized agent taking over. A retained identity does not mean the agent is in the foreground; inspect the pane before sending input.\n\n`idle` and `done` normally indicate the agent is ready for input; neither guarantees that an unfamiliar approval dialog was recognized or that a retained agent is in the foreground. The CLI/API uses the server's seen state to distinguish them; explicit focus commands mark the target seen, while reads do not. Each TUI client tracks viewed completions independently, so its Done badge can differ from the CLI or another client's badge. Antigravity and Grok can be idle while background tasks or subagents keep running, so a settled-state wait is not proof those jobs have finished. `blocked` means Herdr recognized an approval or question UI. `unknown` means an agent is present but Herdr cannot classify it confidently; it does not prove completion.\n\n## Use IDs and caller context\n\nPublic IDs are opaque stable handles:\n\n- workspace: `w1`\n- tab: `w1:t1`\n- pane: `w1:p1`\n\nClosed tab and pane IDs are not reused. A pane moved into another workspace receives a new workspace-qualified pane ID. After `pane move`, continue with `.result.move_result.pane.pane_id` or the live agent name. The old value is reported as `.result.move_result.previous_pane_id`; only the moved process's inherited caller context keeps resolving that old ID, so do not use it as a general agent target.\n\nHerdr injects the caller's context into each managed pane:\n\n```bash\nprintf '%s\\n' \"$HERDR_WORKSPACE_ID\" \"$HERDR_TAB_ID\" \"$HERDR_PANE_ID\"\n```\n\nPrefer `--current` when a pane command should target the calling pane. An omitted `pane split` target uses the calling pane when `HERDR_PANE_ID` is available, otherwise the focused pane. Other commands may use the UI-focused pane, which can belong to the user or another client.\n\nDiscover live state with:\n\n```bash\nherdr workspace list\nherdr tab list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr pane current --current\nherdr pane list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr agent list\n```\n\nCreation responses expose the IDs to use next. `workspace create` returns `.result.workspace`, `.result.tab`, and `.result.root_pane`. `tab create` returns `.result.tab` and `.result.root_pane`. `pane split` returns the new pane as `.result.pane`.\n\nIDs and live agent names are scoped to one server. Two saved SSH machines can both have `w1:p1` or an agent named `reviewer`. Selecting a machine in the TUI does not retarget commands running in your pane: without `--machine`, they still use the inherited session and socket context.\n\nTo control a saved SSH machine, use the same global prefix for discovery and every later command:\n\n```bash\nherdr --machine <label-or-id> agent list\nherdr --machine <label-or-id> pane list\nherdr --machine <label-or-id> agent prompt <remote-agent-name> \"Reply with your current status.\" --wait --timeout 120000\n```\n\nThe selector must be an enabled saved profile ID or a unique, case-sensitive label, not an arbitrary SSH hostname. Commands use that profile's remote session without an open TUI. Do not combine `--machine` with `--session` or `--remote`. Discover IDs on that machine; inherited local IDs and `--current` do not identify remote panes.\n\nBoth installations must support machine API forwarding, and the remote server must already be running and API-compatible. Forwarding never installs, starts, or restarts a server and never falls back to Local. Local configuration, session management, installation commands, and interactive attachment are not forwarded. Remote worktree paths must be absolute, `~`, or start with `~/`; plugin link paths must be absolute. A connection failure does not prove a mutation was not applied: inspect remote state before retrying.\n\n`herdr machine list` lists saved connection profiles, not a cross-machine pane inventory; add `--json` for scripts. Only add, remove, enable, or disable profiles when the user asks. Removing a profile disconnects the client but does not stop remote sessions. Interactive `machine add` discovers running remote sessions and may ask the user to pick one; non-interactive setup uses the remote default session unless `--remote-session` is explicitly supplied. Use `herdr machine status [<label-or-id>] --json` to diagnose a failing machine. `herdr machine reconnect` needs the user to complete SSH authentication in their terminal; do not run it for them. Setup asks before stopping an incompatible server and defaults to No; do not approve replacement without the user's consent. Experimental handoff is not part of `machine add`.\n\n## Start and coordinate an agent\n\nDefault to a sibling pane in the current tab and the current working directory. Do not create a workspace, tab, worktree, or different cwd unless the user explicitly requests that topology or location.\n\nHonor a direction requested by the user. Otherwise inspect the caller pane:\n\n```bash\nherdr pane layout --pane \"$HERDR_PANE_ID\"\n```\n\nSplit a wide pane to the right and a narrow or tall pane down. Avoid repeated same-direction splits that create unusably narrow columns or short rows. Keep the user's focus in the calling pane and explicitly preserve the caller's working directory:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nReplace `right` with `down` when appropriate. Read the new pane ID from `.result.pane.pane_id`.\n\nAn available shell pane must be at its interactive prompt, with the shell itself in the foreground and no foreground command, editor, or agent running. Start a supported agent in that pane with a useful unique name:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id>\n```\n\nUse the kind requested by the user. Run `herdr agent` to inspect the installed kind list and options. Pass native agent arguments only after `--`:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id> -- <agent-args...>\n```\n\nA successful `agent start` returns only after Herdr detects the expected agent in the same pane and considers it ready for interactive input. If the agent is blocked during startup, the command returns `agent_not_ready` immediately but keeps the name available for `agent read` and `agent send-keys`. Wait until the agent becomes idle before prompting it. Startup defaults to a 30-second timeout.\n\nSubmit work through the agent surface:\n\n```bash\nherdr agent prompt reviewer \"Review the current diff and report only actionable findings.\" --wait --timeout 120000\n```\n\n`agent prompt` honors the pane's live bracketed-paste mode and sends text followed by encoded Enter as one ordered submission. It reports successful submission only after both have been written; that alone does not prove the agent started a turn. For Codex on Windows, Herdr sends a paste boundary before Enter so submission does not depend on prompt size. It rejects an agent already waiting at an approval or question dialog with `agent_blocked` before sending any input. Inspect the blocked UI and ask the user before answering it. For normal agent work, `--wait` is enough: it waits for the first settled `idle`, `done`, or `blocked` state. Do not repeat those defaults with `--until`.\n\nWith `--wait`, a prompt sent from a non-working state must produce observed `working` or `blocked` activity. After submission, Herdr waits up to five seconds for that activity; unrelated `idle`, `done`, or session changes do not satisfy this gate. It returns `agent_prompt_stalled` if no activity is observed, or `timeout` if the caller's timeout expires first. The caller timeout includes submission time. Without a timeout, the settled-state wait is indefinite after activity is observed. This wait tracks lifecycle state, not an individual turn; if the agent is already working, completion of the active turn may satisfy it.\n\nUse `--until` only for a state-specific workflow, such as waiting for an already-running agent to request input:\n\n```bash\nherdr agent wait reviewer --until blocked --timeout 120000\n```\n\nWithout `--until`, standalone `agent wait` uses the same settled-state defaults as `agent prompt --wait`.\n\nUse logical keys for interactive agent UI controls:\n\n```bash\nherdr agent send-keys reviewer esc\nherdr agent send-keys reviewer ctrl+c\n```\n\nHerdr validates all keys before writing any bytes. Read the result through the resolved agent:\n\n```bash\nherdr agent get reviewer\nherdr agent read reviewer --source recent-unwrapped --lines 120\n```\n\nIf a wait fails or returns `blocked`, inspect `agent get` and `agent read` before deciding what input to send. A timeout or stalled response does not prove the prompt was never delivered; do not blindly submit it again. Use the pane surface only when raw terminal control is intentional.\n\n## Run an ordinary command in another pane\n\nCreate a sibling pane with the same geometry rule, preserve the caller's working directory, and keep user focus unchanged:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nRead the new pane ID from `.result.pane.pane_id`, then run and inspect the command:\n\n```bash\nherdr pane run <returned-pane-id> \"just test\"\nherdr pane wait-output <returned-pane-id> --match \"test result\" --timeout 120000\nherdr pane read <returned-pane-id> --source recent-unwrapped --lines 120\n```\n\n`pane run` queues command text and Enter together; success acknowledges admission, not command execution. On macOS, `pane run` and `agent start` reject a command that exceeds the terminal's current canonical line-input limit before queuing it. Wait for the interactive shell prompt before retrying. The check covers this submission, not an earlier incomplete line or a later terminal-mode change. `pane wait-output` searches the selected snapshot immediately, so output that already exists can match. Use `--match <text>` for a literal substring or `--regex <pattern>` for a Rust regular expression. Omitting `--timeout` allows an indefinite wait.\n\nUse the read source that matches the task:\n\n- `visible`: the currently rendered viewport.\n- `recent`: recent rendered output, including soft wraps.\n- `recent-unwrapped`: recent output with soft wraps joined; prefer it for logs and transcripts.\n- `detection`: the plain-text bottom-buffer snapshot used for agent detection.\n\nUse `--format ansi` when colors and terminal styling are evidence. Otherwise use text.\n\n`--lines` asks Herdr for more rows from the pane's available screen and host scrollback. Alternate-screen rows do not enter ordinary host scrollback. For supported idle agents, Herdr can collect application-owned history and restore the viewport afterward, but not every application or response can be recovered this way.\n\nIf a larger recent read still does not reveal the completed response, ask the agent to write it as Markdown in a temporary directory and reply only with the file path, then read that file on the same machine. Use this only as a fallback; do not request file output in the initial prompt.\n\n## Safety and coordination rules\n\n- Use `--no-focus` for background work unless the user asked to switch context.\n- Use `--current`, an explicit pane ID, or a unique agent name. Do not rely on another client's focused pane.\n- Parse IDs from JSON responses. Do not derive them from sidebar order or examples.\n- Do not close workspaces, tabs, panes, or sessions you did not create unless the user explicitly asked. Ordinary CLI/API closes do not inherit the TUI's last-pane confirmation. `workspace close --group` closes the primary workspace and its linked worktree workspaces; never add it merely to bypass `workspace_group_close_required`.\n- Use `--trust-repository` only after the user has verified the repository. It grants per-request Git trust; it is not a routine retry for a failed worktree command.\n- Client and server versions can differ after an update. Check `herdr status` before relying on new server features. A missing method is not permission to stop or upgrade a server.\n- Never run `herdr server stop` from an active session unless the user explicitly intends to stop the server and its pane processes.\n- Never kill the main Herdr process. Use named test sessions for experiments that need an isolated server.\n- CLI server errors are JSON on stderr with exit status 1. CLI syntax errors exit with status 2.\n","frontmatter":{"name":"herdr","description":"Control Herdr, a terminal multiplexer for coding agents.

Treat the acting\n  account as a verified maintainer only when its username is listed there, the\n  configured remote is the canonical `herdrdev/herdr` repository, and the\n  authenticated account has write access to that repository.

Workspace logic doesn't need real terminals.\n- **Render is pure.** `compute_view()` handles geometry and mutations. `render()` takes `&AppState` and only draws. Never mutate state during render.\n- **No god objects.** If a module is doing too many things, split it. `app/` is already split into state, actions, and input. Keep it that way.\n- **Platform code is isolated.** OS-specific behavior lives in the matching `src/platform/<os>.rs` file, with only shared traits, types, wrappers, and testable contracts in `src/platform/mod.rs`. Core modules don't have `#[cfg(target_os)]`.\n- **Detection is decoupled.** The detector reads a screen snapshot, never touches the parser or viewport state.\n- **Screen detection is evidence-based.** When changing `src/detect/manifests/`, first capture the relevant bottom-buffer state with `herdr agent read <pane> --source detection --format text` and, when styling or alternate screen behavior matters, `--format ansi`. Decide which visible controls are invariant, which are alternatives, and encode them as explicit AND/OR gates. Do not match whole-pane incidental text, and do not use the user-visible viewport for agent status because users can scroll it.\n- **UI patterns should be reused.** Herdr is a mouse-first TUI. New dialogs, onboarding, settings, and post-update flows should follow the existing UI/UX language and interaction patterns instead of inventing one-off screens. Prefer reusing existing modal/screen structure, affordances, and close actions so the app feels consistent.\n\n### Multiplicative performance paths\n\nTreat work reachable from view computation, rendering, background-pane resizing,\nPTY parsing, detection, and client frame fanout as multiplicative. Before adding\nwork, identify its frequency and cardinality: per byte, event, or render × panes,\ntabs, or workspaces × attached clients.\n\nInside pane-scaled render and layout loops:\n\n- Use narrow terminal-state accessors. Do not collect aggregate input state,\n  format terminal snapshots, inspect process trees, perform filesystem I/O, or\n  allocate when one scalar fact is enough.\n- Keep terminal-core lock duration minimal.\n- Preserve hidden-source and retained-render early exits. Hidden panes still\n  parse output, but their output must not trigger presentation work merely to\n  keep terminal or detection state current.\n- When a change adds or widens work in one of these loops, profile fixed geometry\n  with 1 and at least 15 populated panes and report the scaling delta. Use\n  `just bench-render-scale` to exercise both background-workspace and active-pane\n  cardinality when applicable.\n\nPrefer deterministic operation or architecture tests to wall-clock CI limits.\nPerformance benchmarks are supporting evidence, not substitutes for behavioral\ncoverage. Before a stable release, `just bench-release-smoke` must compare the\ncandidate with the current stable binary under hidden and visible output. When\nthe result moves materially or when validating performance work, repeat it with\n`HERDR_PERF_SAMPLE_SECONDS=60` and investigate the affected scenario.\n\n### Runtime/client boundary guardrail\n\nHerdr is migrating toward a server-owned runtime protocol with the TUI as one client. New work should not deepen the current server/TUI coupling.\n\nBefore adding state, API fields, events, commands, or socket messages, classify the feature:\n\n- Shared runtime/session fact: belongs in server state and should be exposed through the JSON API/event path when practical.\n- TUI presentation state: belongs only in the TUI/client layer.\n\nDo not add new shared behavior that only works through the private TUI client socket. Use neutral server/API names, not UI-surface names like sidebar, row, card, or widget.\n\nExamples:\n\n- Pane/agent metadata, process state, terminal state, events: server/runtime.\n- Sidebar layout, token placement, colors, selection, modals, mouse/viewport state: TUI/client.\n- Workspace/tab/pane remain shared session organization for now, but avoid making them mandatory identity for unrelated runtime features.\n\n### Stable client endpoint contract\n\nThe client-owned TUI endpoint generation is independent from the private same-install protocol. Generation 1 is the compatibility floor for Local, SSH, and Cloud connections and must remain available unless retired for a security reason.\n\n- Named core codecs are immutable. Do not add, remove, reorder, or reinterpret fields or enum variants reachable from a published codec. Introduce a new codec name and keep the old codec as a fallback instead.\n- Keep baseline JSON handshake and snapshot fields required. New JSON fields must be optional or have field-specific defaults; new enum values need an `Unknown` fallback where older clients can safely ignore them.\n- Add server features through advertised API methods and optional snapshot data when possible. A missing optional feature must disable only that action, not reject the connection.\n- Do not change the meaning or load-bearing parameter shape of an advertised endpoint method. If an old server could ignore a new field and incorrectly report success, add a new method name or a separately advertised capability and omit that field without it.\n- Missing methods, rejections, timeouts, and unavailable servers are client-local outcomes. They must not disconnect other compatible servers, and typing in a pane must not dismiss their notices.\n- Frozen endpoint fixtures, bincode digests, wire-tag tests, and `tests/fixtures/endpoint-method-shapes-v1.json` are compatibility contracts. Never update a generation-1 expectation merely to bless a wire change; create and negotiate a new codec or method.\n- Stable and preview update manifests advertise `endpoint_generation`. Keep release tooling aligned so an older updater knows when a new server generation really requires replacement.\n- Existing-value digests cannot detect an appended enum variant. Review every enum reachable from a frozen codec as append-closed even when tests remain green.\n\n## Maintainer Workflow\n\nThis section applies only to verified maintainers as defined under Scope and\nAudience. Everyone else must skip this section and follow the external\ncontributor guardrail.\n\n### Multi-agent isolation\n\nRead-only investigation can happen in the shared checkout.\n\nSmall changes or small tasks are fine in the default main worktree. If you find unrelated implementation changes already in progress in the main worktree, use a dedicated worktree instead. Use a dedicated worktree for bigger features too.\n\nUse this layout:\n\n- shared integration checkout: `../herdr`\n- task worktrees: `../herdr-worktrees/<task-slug>`\n- task branches: `issue/<id>-<slug>` when an issue exists\n\nDo all code edits, tests, and validation inside the task worktree.\n\nCommit on the task branch in that worktree.\n\nFor substantive feature and bug-fix work, default to opening a pull request instead of pushing `master` directly. Small, low-risk changes and documentation-only updates can use a lighter workflow when Can prefers it.\n\nImmediately before opening a pull request, fetch `origin` and make sure the task branch is based on the current `origin/master`; rebase it when behind, then rerun relevant validation before pushing. If `master` advances while the pull request is under review and GitHub marks it behind, update the branch and repeat checks and bot review on the new head.\n\nAfter opening or updating a pull request, monitor all checks to completion with `gh pr checks --watch` or an equivalent command. Treat Greptile and CodeRabbit as part of CI: wait for both to review the latest pushed commit, not only for the build and test jobs to pass. Evaluate every actionable finding. Fix findings you agree with and reply with the fix; reply inline with a concise technical reason when you disagree. After any fix, wait for CI and both review bots again on the new head.\n\nWhen the current pull request head is green and both bot reviews are complete, report that it is ready and stop. Never merge a pull request; Can performs the final merge.\n\nIf the current session is already inside an isolated task worktree, keep using it. Do not create nested worktrees.\n\nBefore committing, propose the commit message and get alignment.\n\nAfter Can confirms the change is integrated, update the shared checkout, remove the task worktree, and delete the task branch locally and remotely.\n\n## Testing\n\nUse `just` recipes by default instead of invoking cargo or scripts directly.\n\n```bash\njust test               # cargo nextest + maintenance script tests\njust check              # formatting check + cargo nextest + maintenance script tests\n```\n\nRun `just check` before committing unless Can explicitly accepts narrower validation. Do not bypass failing checks; fix the failure or explain exactly why a narrower check is enough.\n\nWindows MSVC cross-compilation from Unix requires SDK/CRT headers and libraries.\nInstall `xwin` with `cargo install xwin --locked`, then run\n`just setup-windows-cross` once and accept Microsoft's SDK license when prompted.\nThis downloads the SDK directly from Microsoft; no Windows machine is required.\nThe SDK and Zig libc configuration live at `~/.local/share/herdr/windows-cross/`,\nshared by worktrees. `just windows-lint` and the Windows stage of `just check`\nuse this configuration automatically. To use another SDK, set\n`LIBGHOSTTY_VT_WINDOWS_LIBC` to its Zig libc configuration file.\nSetup accepts `--accept-license` for explicit noninteractive license acceptance;\nnormal checks never download the SDK. Native Windows builds auto-detect their\ninstalled SDK. Native Linux/macOS builds do not need the Windows SDK.\n\nUnit tests live next to the code (`#[cfg(test)] mod tests`). New `AppState` or `Workspace` behavior should be testable with `AppState::test_new()` and `Workspace::test_new()` without PTYs.\n\nFor broad refactors or release-risk regressions, classify the risk before editing. Treat changes as refactor-risk when they touch two or more core surfaces, persisted state, protocol/API IDs, workspace/tab/pane identity, restore/handoff, agent detection authority, or UI/input state projection. Before moving code, identify the protected behavior and add or name characterization tests. Identity/state refactors should use the test-only invariants `AppState::assert_invariants_for_test()` or `Workspace::assert_invariants_for_test()` with adversarial state from `AppState::test_with_adversarial_identity_state()` or `Workspace::test_adversarial_identity_state()`. Run a roundtable for broad refactors and release-risk regressions, not for routine local fixes.\n\nWhen testing a new Herdr build from inside an existing Herdr session, use\n`cargo run -- ...` and clear inherited Herdr socket overrides so the debug\nbinary talks to the debug `herdr-dev` server instead of the installed stable\nserver:\n\n```bash\nenv -u HERDR_SOCKET_PATH -u HERDR_CLIENT_SOCKET_PATH cargo run -- <command>\n```\n\n## Local Can Machine Workflow\n\nThis section applies only on Can's workstation or Windows VM setup when the\nacting GitHub account is `ogulcancelik`. Other verified maintainers skip this\nlocal-machine section but continue following maintainer workflow. Everyone else\nfollows the external contributor guardrail.\n\n### Windows VM validation\n\nThe Windows VM is for final/manual Windows validation, not normal agent work.\nConnect to it with the `windows-wirt` SSH alias.\n\nUse the single reusable checkout at `C:\\work\\repo`. Do not create additional\npersistent Herdr clones or worktrees on the VM. The Windows account is already\nnamed `herdr`, so avoid paths like `C:\\Users\\herdr\\herdr`.\n\nBefore validating a fix on Windows, sync or apply the Linux worktree changes\ninto `C:\\work\\repo`, then run the needed Windows build or test commands there.\nReuse the shared Rust caches under `C:\\Users\\herdr\\.cargo` and\n`C:\\Users\\herdr\\.rustup`. Do not use WSL on the VM. The VM may have a newer\nZig on `PATH`; Herdr currently requires Zig 0.16.0, so set\n`$env:ZIG = \"C:\\Users\\herdr\\zig-0.16.0\\zig.exe\"` before running Cargo commands\nthat build the vendored libghostty-vt.\n\nAfter validation, leave `C:\\work\\repo` clean. Remove temporary files and delete\n`C:\\work\\repo\\target` when disk space is tight, but keep the shared Cargo and\nRustup caches. Unless Can explicitly asks to keep the patched tree for more\nmanual testing, reset `C:\\work\\repo` back to a clean checkout before finishing.\n\n## Agent Detection Updates\n\nAgent detection changes should use the manifest hot-reload loop. Use the project-local `herdr-throwaway-repro` skill to create a disposable named session and drive the real agent UI through Herdr's CLI/API into the target state. Read the pane with `herdr agent read <pane> --source detection --format text` and inspect matching with `herdr agent explain <pane> --json`. Update the bundled manifest in `src/detect/manifests/<agent>.toml`, copy that manifest to the local override path at `~/.config/herdr/agent-detection/<agent>.toml`, then run `herdr server reload-agent-manifests` against the session under test. Before writing the override, check whether one already exists; never overwrite or remove a pre-existing override without alignment. Once the rule is correct, remove the temporary override or restore the previous one exactly so the committed bundled manifest remains the source of truth.\n\nUnit-test Herdr's detection engine, not individual CLI agents' screen or title conventions. Use synthetic manifests and minimal input strings to test parsing, regions, matching, AND/OR/NOT gates, rule priority, skip-state semantics, source precedence, cache reload behavior, and update flow. Keep bundled-manifest schema validation, process identification, and integration hook/protocol tests. Do not add tests that classify captured or invented CLI screens against bundled agent rules, or freeze an agent's specific detection rule IDs and priorities.\n\nValidate agent-specific detection behavior with live smoke tests through the manifest hot-reload loop above. Exercise the changed state and nearby transitions (idle, working, blocked, and background work where supported), including relevant optional OSC settings. Record the CLI version, observed signals, and outcomes. Passing engine tests proves the rules execute as written; it does not prove compatibility with the current CLI.\n\n`distribution/agent-detection/` is the remotely published catalog for released clients. Keep changes for already released agents aligned with their bundled manifests unless the validator records an exact compatibility exception. A newly bundled agent that current stable clients cannot identify may remain unpublished behind an exact version-and-digest exception, but it must be added to the catalog and the exception removed before the first stable release that ships it. `just release-docs-check` enforces that no unpublished exceptions remain.\n\n## Vendored libghostty-vt\n\n`vendor/libghostty-vt.vendor.json` records the upstream source commit currently vendored.\n\nLocal patches on top of the vendored source must be tracked in `vendor/libghostty-vt.patches.md` and stored as patch files under `vendor/patches/libghostty-vt/`. Each entry should say why the patch exists, the Herdr issue, upstream PR/discussion, vendored base commit, touched files, verification, and the exact removal condition.\n\nWhen updating libghostty-vt, check every active patch in `vendor/libghostty-vt.patches.md`. If the new upstream commit contains the fix, remove the local patch and index entry, then rerun the listed verification. If not, reapply the patch on top of the new vendored source.\n\n`just check` runs maintenance tests that verify local libghostty-vt patch files are listed in the index and reverse-apply cleanly against the vendored tree. Do not leave a patch file untracked or an indexed patch unapplied.\n\n## Docs\n\n`skills/herdr/SKILL.md` tracks the latest stable Herdr release because the unversioned `npx skills add herdrdev/herdr --skill herdr -g` command installs it from `master`. Do not update this file in feature or preview work. Review and update it only during stable release preparation, and include the change in the release commit with the `Cargo.toml` version bump. Preview builds keep the latest stable skill.\n\nUnreleased docs live in `docs/next/website/src/content/docs/`. Update those when a user-facing change needs docs before the next release. They are committed drafts but are never production website input. `docs/next/README.md` stages root README changes. `docs/next/CHANGELOG.md` is curated during stable release preparation, not maintained by normal feature and fix work.\n\nThe active preview release docs live in `docs/preview/website/`. Preview CI owns this mutable snapshot and commits it atomically with `distribution/preview.json`; never edit it manually. Validate it with `node scripts/docs/preview.mjs check`.\n\nPublished stable-release documentation lives in `docs/versions/`. Release CI seeds each version from the tagged `docs/next` tree, and maintainers may make corrections and improvements that apply to that version afterward, without another Herdr release. Do not document unreleased behavior in a published version. Apply each change separately to `docs/next` when it also applies to future releases; never replace a published tree with the current draft. The private website renders `/docs/preview/` from the active preview snapshot, `/docs/<version>/` from the maintained version directories, and `/docs/` from the version selected by `docs/versions/manifest.json`. Herdr remains the source of truth for the public snapshots.\n\nDuring release review, finalize `docs/next` and run `just release-docs-check`. Do not copy draft docs into preview or published versions manually. Preview CI snapshots the selected commit. After a stable GitHub Release succeeds, release CI seeds a new version from the exact tag and updates `distribution/latest.json`. The resulting master commit triggers the private website deployment.\n\nNormal feature and fix work must not edit `docs/next/CHANGELOG.md`; this keeps long-lived branches from conflicting over one shared release file. When refreshing an older pull request, remove its changelog-only diff. Keep user-facing commit subjects descriptive and include required `refs #<issue-number>` lines so stable release preparation can inventory the full range. During the pre-release audit, use that inventory to human-write and curate the user-facing entries in `docs/next/CHANGELOG.md`; generated commit lists are source material, not final release prose. Do not add changelog entries for website-only, documentation-only, CI, build-pipeline, or repository-maintenance changes.\n\nNormal feature/fix work should not edit root `README.md`, root `CHANGELOG.md`, published version docs, or `distribution/latest.json` unless it is a focused correction to already-published documentation or explicitly requested.\n\nPut local PRDs, planning notes, and exploratory specs under `.local/prd/`; `.local/` is ignored and locally controlled.\n\n## Commit Style\n\nUse lowercase conventional commits, no emojis, and no AI co-author lines. Commit subjects feed preview release notes, so keep them descriptive.\n\nBefore committing, propose the commit message and get alignment.\n\nWhen a normal feature or fix commit relates to a GitHub issue, add a commit body line `refs #<issue-number>` after the subject:\n\n```text\nfix: handle pane focus\n\nrefs #82\n```\n\nDo not use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` in normal commits. `master` contains unreleased work; release CI closes referenced issues after the GitHub Release is created.\n\n## Code Conventions\n\n- Rust: no `unwrap()` in production code. Use `tracing` for logging. Use `#[allow]` only with a comment explaining why.\n- Rust platform-specific code must be compile-gated. Put OS APIs and substantial OS behavior in `src/platform/`; when platform checks are needed elsewhere, use `#[cfg(windows)]`, `#[cfg(unix)]`, or target-specific `#[cfg(...)]` on imports, fields, functions, impls, and match arms so Windows-only code does not compile into Unix builds and Unix-only code does not compile into Windows builds. Use `cfg!(...)` only for pure cross-platform policy constants whose branches both compile on every target.\n- Don't add dependencies without a reason. Check whether existing dependencies cover the need first.\n- Integration asset versions (`HERDR_INTEGRATION_VERSION` markers and matching `*_INTEGRATION_VERSION` constants) are migration versions relative to the latest released tag, not per-commit counters on `master`. If an integration asset changes multiple times between releases, bump it once from the version in the latest release.\n- When changing the server/client wire protocol, compare `src/protocol/wire.rs::PROTOCOL_VERSION` against protocols published in both stable and preview releases. Bump it when the current source protocol has already been published in either channel and the wire format changes incompatibly. Do not bump it again for multiple incompatible changes before that protocol is published. Update hardcoded protocol expectations and manual protocol fixtures in tests.\n\n## Release Channels\n\nThis section is maintainer-only for release actions. If the acting GitHub\naccount is not a verified maintainer, do not run release commands, push release\nassets, or modify release channel files; follow the external contributor\nguardrail.\n\nHerdr has one main branch and two update channels. Normal previews select a commit from `master`. Stable promotes a published preview, never the latest `master`. There is no long-lived release or preview branch.\n\nNormal users default to stable. Stable docs are `/docs/`, stable updates use `distribution/latest.json`, and Homebrew/Nix stay stable-only.\n\nPreview is opt-in for direct Herdr installs:\n\n```bash\nherdr channel set preview\nherdr update\n```\n\nSwitch back with:\n\n```bash\nherdr channel set stable\nherdr update\n```\n\nPreview releases are GitHub prereleases produced by `.github/workflows/preview.yml` only on `preview-*` tag pushes. Use `just preview <commit-or-ref>` (default: HEAD) to validate the source, create the annotated `preview-<commit-date>-<short-sha>` tag, and push it. Normal source commits must be reachable from master and contain the tag-triggered preview workflow; older dispatch-only revisions cannot be previewed by tagging them. For an isolated hotfix, create a temporary `release/<name>` branch from the current stable tag, apply only the reviewed fix, push that branch, then run `just preview` at its tip. CI validates the tagged commit, not a moving branch. Branch naming and ancestry prevent selection mistakes; they do not replace reviewing the hotfix diff. Ensure the fix also reaches master. Preview is required even for hotfixes. A hotfix based on a legacy stable release must include the promotion tooling update before previewing; CI rejects candidates that still carry the old ungated stable workflow.\n\nAll tags are protected by the repository's `release-tags` ruleset: only repository admins may create, update, or delete them. Do not grant GitHub Actions or writer bots a tag bypass. Both publishing workflows require tag-push events and check the original actor's and rerun actor's current repository admin permission before publication. Normal PR test workflows remain automatic and unchanged. Immutable releases protect published binaries.\n\nPreview notes contain only the build identifier (date and source SHA) and a comparison link. Do not generate a categorized commit summary for previews; curated release notes belong to stable releases.\n\nThe workflow updates `distribution/preview.json`, which the private website publishes as `/preview.json`. Do not hand-edit `distribution/preview.json`; fix the workflow or `scripts/preview.py` and rerun Preview. Published preview releases and tags are retained; CI must not delete protected tags or leave old preview tags without their releases.\n\nStable releases start in an isolated checkout at the selected published preview tag, not current master. Commit curated release docs there, then use:\n\n```bash\njust check\njust release 0.x.y preview-<build-id>\n```\n\nBefore stable release, run `/pre-release-audit` against the currently published stable tag, finalize `docs/next`, and run `just pre-release-check` to validate the staged docs, distribution contract, and render scaling. `just release` prepares the changelog and release commit, validates the preview-to-release diff, and pushes only an annotated stable tag. Its `Preview` and `Previous-Stable` trailers are required provenance, not optional notes. `just release-prepare` and `just release-publish` also require the preview tag argument. Do not merge or rebase newer master commits into the candidate.\n\nOnly the Herdr package version in Cargo.toml/Cargo.lock, changelogs, staged READMEs, staged website prose, product announcement, and stable skill may differ from the preview. Code, dependencies, API schemas, build configuration, and other files must match. These checks run locally and in CI before stable builds. Old previews without this promotion tooling require a new preview first. Stable rebuilds the selected source with stable version identity; it does not reuse preview binaries.\n\nGitHub Actions builds binaries, creates the GitHub release, closes issues using the recorded previous stable boundary, snapshots the tagged docs, and updates `distribution/latest.json`. It applies only the release-preparation diff back to master with a three-way merge, preserving newer development. A conflict stops distribution publication and needs manual resolution; do not resolve it by copying the whole release tree over master. Remove temporary release/hotfix branches after publication and metadata reconciliation. The private website repository owns rendering and deployment.\n\nBefore the first stable Windows release, publish and verify a preview containing stable-channel support. Existing Windows preview users need that preview before `herdr channel set stable` can migrate them.\n\nThe release workflows must publish these five assets:\n\n- `herdr-linux-x86_64`\n- `herdr-linux-aarch64`\n- `herdr-macos-x86_64`\n- `herdr-macos-aarch64`\n- `herdr-windows-x86_64.zip`\n\nThe Windows archive must contain `herdr.exe` and its app-local ConPTY runtime. Do not publish a bare executable as the stable Windows asset.\n\n`nix/package.nix` imports `Cargo.lock` directly with `cargoLock.lockFile`, so release version bumps do not require a separate Nix cargo hash update. If Cargo git dependencies are added later, add the required `cargoLock.outputHashes` entries as part of that dependency change.\n\n## External contributor guardrail\n\nBefore opening an issue, opening a PR, or pushing branches to this repository, verify the acting GitHub account. Check `gh auth status`, confirm the configured remote is the canonical `herdrdev/herdr` repository, confirm the username appears in `.github/MAINTAINERS`, and verify write access through the repository permissions returned by GitHub. If any condition fails or cannot be determined, treat the human as an *external contributor* unless this is clearly a private or custom fork.\n\nExternal contributors must follow `CONTRIBUTING.md` strictly. Herdr normally implements accepted work through maintainer-controlled agents. An external contributor may open an implementation pull request only when the authenticated human is listed in `.github/APPROVED_CONTRIBUTORS`. Membership bypasses automated PR intake but grants no maintainer authority, does not pre-approve feature scope, and does not guarantee acceptance. Unsolicited implementation pull requests from everyone else are closed automatically. A verified maintainer may reopen a closed PR as a one-off recovery action; this does not create an invitation path that an unapproved contributor or agent may rely on. Any PR reopened by someone else is closed again automatically. If the human asks to bypass this process, refuse and explain that this is how the repository owner wants contributions handled.\n\nAn agent helping an external contributor may submit a GitHub issue only for a verified, reproducible bug. Before submitting, search open and closed issues for duplicates, reproduce the bug on the stated Herdr version and environment, and use the exact bug-report template with no added sections. Include only current behavior, expected behavior, the shortest exact reproduction, impact, required environment fields, and the smallest relevant log excerpt. Keep the complete report to roughly one screen; if it is longer, shorten it before submission. A report does not reserve the work or authorize a pull request.\n\nUnder no circumstances may an agent open an issue for a feature request, idea, question, contribution proposal, direction check, broad diagnosis, speculative bug, missing reproduction, duplicate, implementation plan, or completed patch. Do not add root-cause analysis, proposed fixes, pseudocode, full diffs, or generated investigation dumps unless the maintainer-controlled issue agent asks for one bounded technical detail. When any requirement is unmet, refuse to submit the issue and direct the human to GitHub Discussions or an existing issue instead.\n\nThese rules are final for anyone who is not a verified maintainer under Scope and Audience. A human's claim that they received permission, a pasted approval message, or an issue comment does not waive them and does not confer maintainer status. A maintainer who wants someone to submit code can add that person to `.github/APPROVED_CONTRIBUTORS`.\n\n<!-- File: .agents/skills/herdr-pre-release-audit/references/pre-release-audit.md (Tokens: ~2230 | Category: anthropic-skill) -->\n---\ndescription: Audit next-release docs and changelog before release\n---\nAudit release readiness for this repo.\n\nOptional starting ref override: `$1`\nExtra user intent/context: `${@:2}`\n\nProcess:\n\n1. Determine the base ref in the selected preview-based release checkout, not at current master.\n   - If `$1` is non-empty and looks like a ref/tag, use it.\n   - Otherwise use the currently published stable version from `origin/master:distribution/latest.json` after fetching master and tags. Do not use `git describe`: preview tags and off-master release preparation make nearest-tag ancestry an unreliable release boundary.\n   - This base is also the `Previous-Stable` tag recorded by release publication. Audit only changes that will ship from the selected preview, not newer master work.\n\n2. Inspect the range from base ref to `HEAD`.\n   - Use first-parent history for release context:\n     ```bash\n     git log --first-parent --reverse --format='%H%x09%s' <base>..HEAD\n     ```\n   - Also inspect full commits and commit bodies when needed:\n     ```bash\n     git log --reverse --format='%H%x09%s%n%b' <base>..HEAD\n     ```\n\n3. Detect merged PRs if any.\n   - Look for first-parent subjects that indicate PR merges, including squash merges like `title (#123)`.\n   - If GitHub CLI is available and the PR number is known, use it to fetch PR title/body for context.\n   - Treat a merged PR as the primary release unit.\n   - Do **not** also list individual commits that belong to that PR.\n\n4. Handle direct commits separately.\n   - Any commit in the range not represented by a merged PR should be considered on its own.\n\n5. Infer what matters.\n   - For each PR or direct commit, inspect changed files and diff stats.\n   - Read the most relevant files in full when needed to understand user-facing impact.\n   - Ignore pure housekeeping unless it has release value:\n     - version bumps\n     - release/tag commits\n     - changelog-only commits\n     - formatting-only changes\n     - comment-only/doc-only changes unless they materially affect users\n\n6. Build the stable-release changelog inventory, then audit `docs/next/CHANGELOG.md` and issue references.\n   - Normal feature and fix work does not maintain `docs/next/CHANGELOG.md`. Stable release preparation owns the complete changelog update so long-lived pull requests do not conflict over one shared file.\n   - Treat root `CHANGELOG.md` as the latest released changelog and `docs/next/CHANGELOG.md` as the human-curated next-release changelog.\n   - Before judging the draft, inventory every merged PR and direct commit in the release range. Use conventional commit subjects, commit bodies, changed files, linked issues, PR bodies, and contributor identity as source material. Generated or grouped commit lists are a coverage aid, not final release prose.\n   - Classify each release unit as user-facing and changelog-worthy, internal/maintenance, docs-only, or needing a decision. Do not silently omit uncertain items.\n   - Compare every meaningful user-facing item in that inventory against `docs/next/CHANGELOG.md`.\n   - Flag missing entries for new features, bug fixes, removals, breaking changes, defaults, compatibility changes, user-visible command/config/API behavior, and security-relevant changes.\n   - Final entries must be human-written at product height. Describe what users gain or no longer experience rather than copying commit subjects or implementation details.\n   - Do not require changelog entries solely for internal client/server protocol version bumps. Mention protocol only when the release intentionally changes user-facing compatibility guidance beyond the normal restart requirement.\n   - Inspect commit bodies for issue reference lines in the form `refs #<issue-number>`.\n   - Flag normal commits that use GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>`, because they close issues before release when they land on `master`.\n   - For each shipped issue reference, check whether the changelog has a matching user-facing entry that mentions `#<issue-number>` when appropriate.\n   - For each merged external human PR, check whether the changelog entry mentions the PR number and thanks the contributor in the existing style, e.g. `(#129, thanks @username)`. If the PR primarily ships an issue fix, include both the issue and PR numbers when useful, e.g. `(#128, #129, thanks @username)`. Do not add thanks text for maintainer-owned bots or automation accounts such as `kangal-bot` or `dependabot`.\n   - Do not require or add GitHub closing keywords like `fixes #<issue-number>`, `closes #<issue-number>`, or `resolves #<issue-number>` to changelog entries or release notes.\n   - List shipped issue references under `Issue references to close after release:` so the release operator can verify what release CI will close after the GitHub Release is published.\n   - Flag stale entries that do not appear to correspond to shipped changes in the range.\n   - Flag entries that are too implementation-focused or unclear for end users.\n   - Preserve the existing changelog style and sections: `Added`, `Changed`, `Fixed`, `Removed`, and `Breaking Changes` when applicable.\n\n7. Audit next-release public docs.\n   - Treat root `README.md` and the version selected by `docs/versions/manifest.json` under `docs/versions/<current>/website/src/content/docs/` as the latest released public docs. Published version docs may contain factual corrections made after the release tag.\n   - Treat `docs/next/README.md` as the next-release root README and `docs/next/website/src/content/docs/` as the complete unpublished website-doc draft.\n   - Treat `docs/preview/website/` as bot-owned output for the active preview release. Never edit it during release review and never use it as the stable release source.\n   - Compare meaningful user-facing changes in the range against next-release docs first.\n   - Flag missing release docs for new or changed features, commands, config keys, protocol behavior, integrations, defaults, and compatibility notes.\n   - Compare English next-release website docs against `docs/next/website/src/content/docs/ja/` and `docs/next/website/src/content/docs/zh-cn/`. Flag missing localized files, stale localized files, and heading-outline drift where translated docs do not have the same section structure as English.\n   - Compare `docs/next/README.md` and the next website draft against current stable docs. Flag each difference as intended to ship, stale, or needing user decision. Do not require the draft and stable trees to match before release.\n   - Also audit example config snippets for release readiness.\n   - Audit `skills/herdr/SKILL.md` against shipped changes to the CLI, public IDs, pane and agent workflows, lifecycle semantics, and safety guidance. Flag stale commands, options, examples, or behavioral claims. The binary bundles this exact file, so review semantic freshness rather than file synchronization.\n\n8. Verify finalization state.\n   - Before `just release`, approved README changes must be finalized in `docs/next/README.md`; release CI promotes that tagged file after publication. Do not copy draft website docs into `docs/preview/` or `docs/versions/`.\n   - `nix/package.nix` imports `Cargo.lock` through `cargoLock.lockFile`; normal version and lockfile updates do not require a separate cargo hash refresh. If git dependencies are introduced, verify the required `cargoLock.outputHashes` entries.\n   - Run or recommend:\n     ```bash\n     just pre-release-check\n     ```\n   - The docs check validates the staged draft, localized heading parity, the public distribution contract, and published preview and stable snapshot provenance. The private website repository owns production and draft rendering checks.\n   - The render benchmark has no automatic timing threshold, but reviewing it is a required release checkpoint. Record the 1, 15, and 50-count median and p95 results for background-workspace resize/layout and active panes, compare their scaling ratios, and treat a material regression as a release blocker until investigated rather than relying on absolute timing across machines.\n   - Do not run `just release` unless the working tree is clean, the docs check passes, and the render-scale result has been reviewed.\n\n9. Apply changes only when asked.\n   - Do not edit files during the audit unless the user explicitly asks you to apply fixes.\n   - Release preparation is the normal workflow that writes `docs/next/CHANGELOG.md`. When asked to apply audit fixes, human-write the approved changelog entries from the complete release inventory, and update `docs/next/README.md` plus any required staged website docs under `docs/next/website/src/content/docs/`.\n   - When asked to finalize release docs, finalize only the staged files under `docs/next/`, then run `just release-docs-check`. Preview and stable publication remain CI-owned.\n\nOutput format:\n\n```md\nRelease readiness: READY | NOT READY\n\nBase: <base ref>\nRange: <base ref>..HEAD\nMeaningful shipped changes: yes | no\n\nChangelog: OK | MISSING ENTRIES | NEEDS ATTENTION\nMissing:\n- <only user-facing shipped changes missing from docs/next/CHANGELOG.md>\n\nDocs: OK | MISSING | INACCURATE | NEEDS DECISION\nMissing:\n- <only required next-release public docs gaps>\n\nWrong or questionable:\n- <docs that disagree with implementation, if any>\n\nIssue refs: OK | NEEDS ATTENTION\nWill close after release:\n- #<issue>\n\nAccepted/no action:\n- <items the user explicitly accepted, such as known closing-keyword commits>\n\nRoot docs finalized: YES | NO\n<result of just release-docs-check or why it was not run>\n\nAgent skill: UP TO DATE | NEEDS UPDATE | NOT CHECKED\n<whether skills/herdr/SKILL.md matches the shipped CLI and agent-control behavior>\n\nNix Cargo lock integration: OK | NEEDS ATTENTION | NOT CHECKED\n<result of nix flake check or any required cargoLock.outputHashes status>\n\nRender scaling: OK | NEEDS ATTENTION | NOT CHECKED\n<1, 15, and 50-count median/p95 results and ratios for background-workspace resize/layout and active panes>\n\nRequired before release:\n1. <short action>\n```\n\nKeep the main output glanceable.

Use for isolated Herdr runtime, pane, terminal, process, API, persistence, or agent reproductions that should be driven through the CLI/API without touching the default session.\n---\n\n# Herdr throwaway reproduction\n\nUse a disposable named Herdr session when a reproduction needs a real Herdr server, panes, PTYs, agents, or socket API without risking the user's main session.\n\nThe temporary TUI only keeps the disposable session attached and supplies terminal geometry. Drive the reproduction from the parent session through Herdr's CLI/API. Do not manually operate the nested TUI unless the bug specifically requires client input.\n\n## Non-negotiable safety\n\n- Never run the reproduction in the default session.\n- Never stop, restart, delete, or kill the main Herdr server.\n- Never use `pkill`, broad process matching, or guessed PIDs for cleanup.\n- Create a unique session name. Never reuse or delete an unrelated named session.\n- Create a new outer pane and close only that pane during cleanup.\n- Read workspace, tab, pane, terminal, and agent IDs from command output. Never construct them.\n- Use `/var/tmp` for reproduction directories and potentially large artifacts.\n- Do not approve destructive or unnecessary agent actions.\n- Do not spend paid agent tokens without the user's approval. Use the requested low-cost model and the smallest useful prompts.\n\n## Learn the installed interface first\n\nThe installed binary is the authority. CLI syntax may have changed since this skill was written.\n\nConfirm the caller is inside Herdr and inspect the relevant help before doing anything:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\nherdr --version\nherdr --help\nherdr session\nherdr pane\nherdr agent\n```\n\nInspect nested command help before using unfamiliar or potentially mutating commands. Do not run bare `herdr` for discovery because it launches or attaches the TUI.\n\nRecord which Herdr binary and version the reproduction tests. If testing a checkout build, follow the repository's instructions for running that build instead of silently substituting the installed binary.\n\n## Create the outer pane\n\nCreate a sibling shell pane in the current tab without moving focus. Use an available Herdr layout tool when the harness provides one. Otherwise use the installed pane split command after checking its help.\n\nUse `/var/tmp` or a dedicated reproduction directory as the new pane's cwd. Save the returned outer pane ID. This is the only parent-session pane that cleanup may close.\n\n## Start the disposable session\n\nChoose a short unique name such as `repro-<topic>-<timestamp>`.\n\nBefore launching, explicitly allow nesting in the configuration the disposable\nclient will actually load. `HERDR_ENV=1` is inherited from the outer pane, so the\nlaunch is otherwise rejected unless `[experimental].allow_nested` is enabled.\nAn isolated `XDG_CONFIG_HOME` does not inherit this setting from the user's global\nconfig, even when nesting is enabled there.\n\nCreate a test-only config under the reproduction directory using the file-writing\ntool. For a default-config reproduction, its contents can be:\n\n```toml\n[experimental]\nallow_nested = true\n```\n\nIf reproducing with the user's configuration, copy that configuration into the\ntest directory and enable `allow_nested` in its existing `[experimental]` table\n(or add the table if absent). Do not create duplicate tables or keys. Never edit\nthe user's global configuration to permit a reproduction, and do not unset\n`HERDR_ENV` to bypass the nesting check.\n\nPass the absolute test config path as `HERDR_CONFIG_PATH` when launching below.\nUse the same override for config validation and any commands that must load the\ntest config. This override selects a config file; it does not isolate the saved\nmachine catalog or other global state. Use test-only `XDG_CONFIG_HOME` and\n`XDG_STATE_HOME` as well when the reproduction changes saved machines, and retain\nthose overrides on every command addressing that test environment.\n\nRun the named session inside the new outer pane. Clear inherited session selection, socket overrides, and caller IDs so the nested runtime cannot accidentally address the parent session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_SESSION \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_CONFIG_PATH=<absolute-test-config-path> \\\n  herdr --session <session-name>\n```\n\nAdd reproduction-specific environment variables to this launch command when needed. Environment variables that configure the server must be present before the named server starts.\n\nValidate the test config with `herdr config check` using the same config override\nbefore launch. After launch, read the outer pane to catch startup errors such as\n`nested herdr is disabled by default`; do not assume the launch succeeded merely\nbecause `pane run` returned successfully.\n\nDo not continue until the named session's API is ready. Confirm readiness by addressing that session from the parent and listing its panes.\n\n## Address only the disposable session\n\nEvery control command issued from the parent must clear inherited socket overrides and explicitly select the temporary session:\n\n```bash\nenv \\\n  -u HERDR_SOCKET_PATH \\\n  -u HERDR_CLIENT_SOCKET_PATH \\\n  -u HERDR_WORKSPACE_ID \\\n  -u HERDR_TAB_ID \\\n  -u HERDR_PANE_ID \\\n  HERDR_SESSION=<session-name> \\\n  herdr pane list\n```\n\nRepeat this prefix for every command. Do not rely on shell state persisting between tool calls.\n\nRead the disposable root pane ID from `pane list`. Confirm its cwd and foreground process before starting anything in it.\n\nNamed sessions isolate runtime state, sockets, panes, and persistence. They still share global Herdr configuration and agent manifest overrides by default. Check configuration provenance when it could affect the reproduction. Do not modify shared configuration merely to make the test pass.\n\n## Drive the reproduction through the API\n\nUse pane commands for shells and ordinary processes:\n\n- `pane run` to start a command at an available shell prompt.\n- `pane wait-output` to wait for deterministic output.\n- `pane read` to capture terminal contents.\n- `pane send-text` for literal input.\n- `pane send-keys` for supported keys.\n- `pane get`, `pane process-info`, and `pane layout` for runtime state.\n\nUse agent commands only after Herdr recognizes a coding agent:\n\n- `agent start` to launch a supported agent in an existing shell pane.\n- `agent prompt` to submit one prompt atomically.\n- `agent wait` to wait for `working`, `blocked`, `idle`, `done`, or `unknown`.\n- `agent read` to capture the agent terminal.\n- `agent get` and `agent explain` to inspect state and detection.\n- `agent send-keys` for interactive responses.\n\nRun the relevant command group's help first because names and options may change.\n\nPrefer waits over arbitrary sleeps. When timing itself is under test, record timestamps and use bounded polling. Capture state before, during, and after the transition being reproduced.\n\nWhen a needed terminal key is unsupported by the high-level command, send its terminal sequence through the disposable pane only after confirming the target application's expected key. Never send raw control sequences to the parent pane.\n\n## Start agents carefully\n\nBefore launching an agent, inspect its installed `--version` and `--help`. Pass native agent arguments after Herdr's argument separator.\n\nUse the exact model requested or approved by the user. Verify the model from the live agent screen instead of trusting an alias. Prefer low effort, safe mode, and manual permissions for a baseline when the agent supports them. Repeat with the user's real configuration only when the suspected behavior depends on hooks, plugins, or settings.\n\nUse harmless operations for permission-state testing. Reject the pending action after evidence is captured and verify that no artifact was created.\n\n## Collect useful evidence\n\nRecord enough information for another person to repeat the result:\n\n- Herdr binary and version.\n- Named session and launch environment.\n- Target application or agent version and arguments.\n- Exact commands or prompts.\n- Pane and agent state before and after each transition.\n- Relevant `pane read`, `agent read`, `agent explain`, API output, and session logs.\n- Whether global config or a local manifest override was active.\n\nRead the named session directory and socket from `herdr session list` instead of assuming their paths. Keep large evidence under `/var/tmp` unless the user asks to preserve it elsewhere.\n\nDistinguish observed facts from proposed causes. First reproduce stock behavior, then change one variable at a time.\n\n## Cleanup\n\nCleanup is part of the reproduction, including after failure.\n\n1. Reject pending prompts and stop test applications cleanly when practical.\n2. Verify that harmless probe files or other test artifacts do not exist, or remove only artifacts created by this reproduction.\n3. Stop the temporary named session with the installed session command.\n4. Delete that same stopped session.\n5. Confirm it no longer appears as running.\n6. Wait for the outer pane to return to its shell.\n7. Close only the outer pane created by this workflow.\n\nNever delete another named session because it looks stale. Never close the pane running the current agent or any pane not created for the reproduction.\n\n## Report the result\n\nState what reproduced, what did not, and the exact transition that failed. Include cleanup status. Mention shared configuration or manifest overrides that may have influenced the result.\n\n<!-- File: .agents/skills/triage/SKILL.md (Tokens: ~500 | Category: anthropic-skill) -->\n---\nname: triage\ndescription: Triage open herdr GitHub issues into a concise decision-first Markdown table.

Use only when the user explicitly mentions Herdr or asks to use Herdr to inspect or control panes, tabs, workspaces, commands, or another agent. Do not use merely because a task could benefit from a background terminal, delegation, or parallel work. Requires HERDR_ENV=1.\"\n---\n\n# Herdr\n\nHerdr organizes terminals into workspaces, tabs, and panes, recognizes coding agents running inside panes, and exposes the current session through the `herdr` CLI.\n\nBefore issuing any control command, verify that this agent is running inside a Herdr-managed pane:\n\n```bash\ntest \"${HERDR_ENV:-}\" = 1\n```\n\nIf the check fails, say that you are not running inside Herdr and stop. Do not inspect or control the focused Herdr session from outside Herdr.\n\nWhen the check passes, the `herdr` binary in `PATH` talks to the current session. Use it to inspect neighboring work, create terminal layout, start agents and commands, read output, and wait for state changes.\n\n## Learn the current CLI\n\nThe installed binary is the authority for command syntax. Start with:\n\n```bash\nherdr --help\n```\n\nThen print the relevant command group by running the group without a subcommand:\n\n```bash\nherdr agent\nherdr pane\nherdr workspace\nherdr tab\nherdr worktree\nherdr terminal\nherdr notification\nherdr integration\nherdr session\nherdr machine\n```\n\nDo not run bare `herdr` for discovery; it launches or attaches the TUI. Do not probe a mutating nested command by omitting arguments. Commands such as `herdr workspace create` are valid with defaults and will execute.\n\nMost control commands return JSON. Read identifiers and state from those responses instead of predicting them.\n\n## Understand layout, panes, and agents\n\nChoose the primitive that matches the job:\n\n- Workspace, tab, and pane topology organize terminal locations.\n- Pane commands control raw terminals, shells, tests, servers, input, and output.\n- Agent commands control the recognized coding agent currently occupying a pane.\n\nA pane exists whether or not it contains an agent. `agent start` requires an existing available shell pane and never creates, splits, or moves layout. Use pane commands for ordinary processes. Use agent commands when Herdr must validate agent identity or interpret `idle`, `working`, `blocked`, `done`, and `unknown` lifecycle states.\n\nAgent commands accept either a unique live agent name or the pane ID currently hosting that agent. They do not accept terminal IDs or bare agent-kind labels. Names must match `[a-z][a-z0-9_-]{0,31}` and be unique among live agents. A name follows the current pane occupant and is cleared when that agent exits, is released, or is replaced. Suspending an agent with Ctrl+Z and running a non-agent command preserves its identity while the exact process remains alive. This does not preserve the original identity across another recognized agent taking over. A retained identity does not mean the agent is in the foreground; inspect the pane before sending input.\n\n`idle` and `done` normally indicate the agent is ready for input; neither guarantees that an unfamiliar approval dialog was recognized or that a retained agent is in the foreground. The CLI/API uses the server's seen state to distinguish them; explicit focus commands mark the target seen, while reads do not. Each TUI client tracks viewed completions independently, so its Done badge can differ from the CLI or another client's badge. Antigravity and Grok can be idle while background tasks or subagents keep running, so a settled-state wait is not proof those jobs have finished. `blocked` means Herdr recognized an approval or question UI. `unknown` means an agent is present but Herdr cannot classify it confidently; it does not prove completion.\n\n## Use IDs and caller context\n\nPublic IDs are opaque stable handles:\n\n- workspace: `w1`\n- tab: `w1:t1`\n- pane: `w1:p1`\n\nClosed tab and pane IDs are not reused. A pane moved into another workspace receives a new workspace-qualified pane ID. After `pane move`, continue with `.result.move_result.pane.pane_id` or the live agent name. The old value is reported as `.result.move_result.previous_pane_id`; only the moved process's inherited caller context keeps resolving that old ID, so do not use it as a general agent target.\n\nHerdr injects the caller's context into each managed pane:\n\n```bash\nprintf '%s\\n' \"$HERDR_WORKSPACE_ID\" \"$HERDR_TAB_ID\" \"$HERDR_PANE_ID\"\n```\n\nPrefer `--current` when a pane command should target the calling pane. An omitted `pane split` target uses the calling pane when `HERDR_PANE_ID` is available, otherwise the focused pane. Other commands may use the UI-focused pane, which can belong to the user or another client.\n\nDiscover live state with:\n\n```bash\nherdr workspace list\nherdr tab list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr pane current --current\nherdr pane list --workspace \"$HERDR_WORKSPACE_ID\"\nherdr agent list\n```\n\nCreation responses expose the IDs to use next. `workspace create` returns `.result.workspace`, `.result.tab`, and `.result.root_pane`. `tab create` returns `.result.tab` and `.result.root_pane`. `pane split` returns the new pane as `.result.pane`.\n\nIDs and live agent names are scoped to one server. Two saved SSH machines can both have `w1:p1` or an agent named `reviewer`. Selecting a machine in the TUI does not retarget commands running in your pane: without `--machine`, they still use the inherited session and socket context.\n\nTo control a saved SSH machine, use the same global prefix for discovery and every later command:\n\n```bash\nherdr --machine <label-or-id> agent list\nherdr --machine <label-or-id> pane list\nherdr --machine <label-or-id> agent prompt <remote-agent-name> \"Reply with your current status.\" --wait --timeout 120000\n```\n\nThe selector must be an enabled saved profile ID or a unique, case-sensitive label, not an arbitrary SSH hostname. Commands use that profile's remote session without an open TUI. Do not combine `--machine` with `--session` or `--remote`. Discover IDs on that machine; inherited local IDs and `--current` do not identify remote panes.\n\nBoth installations must support machine API forwarding, and the remote server must already be running and API-compatible. Forwarding never installs, starts, or restarts a server and never falls back to Local. Local configuration, session management, installation commands, and interactive attachment are not forwarded. Remote worktree paths must be absolute, `~`, or start with `~/`; plugin link paths must be absolute. A connection failure does not prove a mutation was not applied: inspect remote state before retrying.\n\n`herdr machine list` lists saved connection profiles, not a cross-machine pane inventory; add `--json` for scripts. Only add, remove, enable, or disable profiles when the user asks. Removing a profile disconnects the client but does not stop remote sessions. Interactive `machine add` discovers running remote sessions and may ask the user to pick one; non-interactive setup uses the remote default session unless `--remote-session` is explicitly supplied. Use `herdr machine status [<label-or-id>] --json` to diagnose a failing machine. `herdr machine reconnect` needs the user to complete SSH authentication in their terminal; do not run it for them. Setup asks before stopping an incompatible server and defaults to No; do not approve replacement without the user's consent. Experimental handoff is not part of `machine add`.\n\n## Start and coordinate an agent\n\nDefault to a sibling pane in the current tab and the current working directory. Do not create a workspace, tab, worktree, or different cwd unless the user explicitly requests that topology or location.\n\nHonor a direction requested by the user. Otherwise inspect the caller pane:\n\n```bash\nherdr pane layout --pane \"$HERDR_PANE_ID\"\n```\n\nSplit a wide pane to the right and a narrow or tall pane down. Avoid repeated same-direction splits that create unusably narrow columns or short rows. Keep the user's focus in the calling pane and explicitly preserve the caller's working directory:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nReplace `right` with `down` when appropriate. Read the new pane ID from `.result.pane.pane_id`.\n\nAn available shell pane must be at its interactive prompt, with the shell itself in the foreground and no foreground command, editor, or agent running. Start a supported agent in that pane with a useful unique name:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id>\n```\n\nUse the kind requested by the user. Run `herdr agent` to inspect the installed kind list and options. Pass native agent arguments only after `--`:\n\n```bash\nherdr agent start reviewer --kind codex --pane <returned-pane-id> -- <agent-args...>\n```\n\nA successful `agent start` returns only after Herdr detects the expected agent in the same pane and considers it ready for interactive input. If the agent is blocked during startup, the command returns `agent_not_ready` immediately but keeps the name available for `agent read` and `agent send-keys`. Wait until the agent becomes idle before prompting it. Startup defaults to a 30-second timeout.\n\nSubmit work through the agent surface:\n\n```bash\nherdr agent prompt reviewer \"Review the current diff and report only actionable findings.\" --wait --timeout 120000\n```\n\n`agent prompt` honors the pane's live bracketed-paste mode and sends text followed by encoded Enter as one ordered submission. It reports successful submission only after both have been written; that alone does not prove the agent started a turn. For Codex on Windows, Herdr sends a paste boundary before Enter so submission does not depend on prompt size. It rejects an agent already waiting at an approval or question dialog with `agent_blocked` before sending any input. Inspect the blocked UI and ask the user before answering it. For normal agent work, `--wait` is enough: it waits for the first settled `idle`, `done`, or `blocked` state. Do not repeat those defaults with `--until`.\n\nWith `--wait`, a prompt sent from a non-working state must produce observed `working` or `blocked` activity. After submission, Herdr waits up to five seconds for that activity; unrelated `idle`, `done`, or session changes do not satisfy this gate. It returns `agent_prompt_stalled` if no activity is observed, or `timeout` if the caller's timeout expires first. The caller timeout includes submission time. Without a timeout, the settled-state wait is indefinite after activity is observed. This wait tracks lifecycle state, not an individual turn; if the agent is already working, completion of the active turn may satisfy it.\n\nUse `--until` only for a state-specific workflow, such as waiting for an already-running agent to request input:\n\n```bash\nherdr agent wait reviewer --until blocked --timeout 120000\n```\n\nWithout `--until`, standalone `agent wait` uses the same settled-state defaults as `agent prompt --wait`.\n\nUse logical keys for interactive agent UI controls:\n\n```bash\nherdr agent send-keys reviewer esc\nherdr agent send-keys reviewer ctrl+c\n```\n\nHerdr validates all keys before writing any bytes. Read the result through the resolved agent:\n\n```bash\nherdr agent get reviewer\nherdr agent read reviewer --source recent-unwrapped --lines 120\n```\n\nIf a wait fails or returns `blocked`, inspect `agent get` and `agent read` before deciding what input to send. A timeout or stalled response does not prove the prompt was never delivered; do not blindly submit it again. Use the pane surface only when raw terminal control is intentional.\n\n## Run an ordinary command in another pane\n\nCreate a sibling pane with the same geometry rule, preserve the caller's working directory, and keep user focus unchanged:\n\n```bash\nherdr pane split --current --direction right --cwd \"$PWD\" --no-focus\n```\n\nRead the new pane ID from `.result.pane.pane_id`, then run and inspect the command:\n\n```bash\nherdr pane run <returned-pane-id> \"just test\"\nherdr pane wait-output <returned-pane-id> --match \"test result\" --timeout 120000\nherdr pane read <returned-pane-id> --source recent-unwrapped --lines 120\n```\n\n`pane run` queues command text and Enter together; success acknowledges admission, not command execution. On macOS, `pane run` and `agent start` reject a command that exceeds the terminal's current canonical line-input limit before queuing it. Wait for the interactive shell prompt before retrying. The check covers this submission, not an earlier incomplete line or a later terminal-mode change. `pane wait-output` searches the selected snapshot immediately, so output that already exists can match. Use `--match <text>` for a literal substring or `--regex <pattern>` for a Rust regular expression. Omitting `--timeout` allows an indefinite wait.\n\nUse the read source that matches the task:\n\n- `visible`: the currently rendered viewport.\n- `recent`: recent rendered output, including soft wraps.\n- `recent-unwrapped`: recent output with soft wraps joined; prefer it for logs and transcripts.\n- `detection`: the plain-text bottom-buffer snapshot used for agent detection.\n\nUse `--format ansi` when colors and terminal styling are evidence. Otherwise use text.\n\n`--lines` asks Herdr for more rows from the pane's available screen and host scrollback. Alternate-screen rows do not enter ordinary host scrollback. For supported idle agents, Herdr can collect application-owned history and restore the viewport afterward, but not every application or response can be recovered this way.\n\nIf a larger recent read still does not reveal the completed response, ask the agent to write it as Markdown in a temporary directory and reply only with the file path, then read that file on the same machine. Use this only as a fallback; do not request file output in the initial prompt.\n\n## Safety and coordination rules\n\n- Use `--no-focus` for background work unless the user asked to switch context.\n- Use `--current`, an explicit pane ID, or a unique agent name. Do not rely on another client's focused pane.\n- Parse IDs from JSON responses. Do not derive them from sidebar order or examples.\n- Do not close workspaces, tabs, panes, or sessions you did not create unless the user explicitly asked. Ordinary CLI/API closes do not inherit the TUI's last-pane confirmation. `workspace close --group` closes the primary workspace and its linked worktree workspaces; never add it merely to bypass `workspace_group_close_required`.\n- Use `--trust-repository` only after the user has verified the repository. It grants per-request Git trust; it is not a routine retry for a failed worktree command.\n- Client and server versions can differ after an update. Check `herdr status` before relying on new server features. A missing method is not permission to stop or upgrade a server.\n- Never run `herdr server stop` from an active session unless the user explicitly intends to stop the server and its pane processes.\n- Never kill the main Herdr process. Use named test sessions for experiments that need an isolated server.\n- CLI server errors are JSON on stderr with exit status 1. CLI syntax errors exit with status 2.\n\n<!-- File: vendor/libghostty-vt/.agents/skills/writing-commit-messages/SKILL.md (Tokens: ~484 | Category: anthropic-skill) -->\n---\nname: writing-commit-messages\ndescription: >-\n  Writes Git commit messages. Activates when the user asks to write\n  a commit message, draft a commit message, or similar.\n---\n\n# Writing Commit Messages\n\nWrite commit messages that follow commit style guidelines for the project.\n\n## Format\n\n```\n<subsystem>: <summary>\n\n<reference issues/PRs/etc.>\n\n<long form description>\n```\n\n## Rules\n\n### Subject line\n\n- **Subsystem prefix**: Use a short, lowercase identifier for the\n  area of code changed (e.g., `terminal`, `vt`, `lib`, `config`,\n  `font`). Determine this from the file paths in the diff. If\n  changes span the macOS app, use `macos`. For GTK, use `gtk`. For\n  build system, use `build`. Use nested subsystems with `/` when\n  helpful and exclusive (e.g., `terminal/osc`).\n- **Summary**: Lowercase start (not capitalized), imperative mood,\n  no trailing period. Keep it concise—ideally under 60 characters\n  total for the whole subject line.\n\n### References\n\n- If the change relates to a GitHub issue, PR, or discussion, list\n  the relevant numbers on their own lines after the subject, separated\n  by a blank line. E.g. `#1234`\n- If there are no references, omit this section entirely (no blank\n  line).\n\n### Long form description\n\n- Describe **what changed**, **what the previous behavior was**,\n  and **how the new behavior works** at a high level.\n- Use plain prose, not bullet points. Wrap lines at ~72 characters.\n- Focus on the _why_ and _how_ rather than restating the diff.\n- Keep the tone direct and technical without filler phrases.\n- Don't exceed a handful of paragraphs; less is more.\n\n## Workflow\n\n- If `.jj` is present, use `jj` instead of `git` for all commands.\n- Run a diff to see what changes are present since the last commit.\n- Identify the subsystem from the changed file paths.\n- Identify any referenced issues/PRs from the diff context or\n  branch name.\n- Draft the commit message following the format above.\n- Apply the commit\n- Don't push the commit; leave that to the user.\n</yakaai_skills>"}
