# Claude Code System Prompts [](https://github.com/hesreallyhim/awesome-claude-code) > [!tip] > **NEW (June 12, 2026):** We've greatly expanded this list with many more of Claude Code's prompts—**from 350 to 515 (+165)**—our most complete coverage yet. This repository contains an up-to-date list of all Claude Code's various system prompts and their associated token counts as of **[Claude Code v2.1.301](https://www.npmjs.com/package/@anthropic-ai/claude-code/v/2.1.301) (October 15th, 2026).** It also contains a [**CHANGELOG.md**](./CHANGELOG.md) for the system prompts across 315 versions since v2.0.14. From the team behind [ **Piebald.**](https://piebald.ai/) **This repository is updated within minutes of each Claude Code release. See the [changelog](./CHANGELOG.md), and follow [@PiebaldAI](https://x.com/PiebaldAI) on X for a summary of the system prompt changes in each release.** > [!note] > ⭐ **Star** this repository to get notified about new Claude Code versions. For each new Claude Code version, we create a release on GitHub, which will notify all users who've starred the repository. --- Why multiple "system prompts?" **Claude Code doesn't just have one single string for its system prompt.** Instead, there are: - Large portions conditionally added depending on the environment and various configs. - Descriptions for builtin tools like `Write`, `Bash`, and `TodoWrite`, and some are fairly large. - Separate system prompts for builtin agents like Explore and Plan. - Numerous AI-powered utility functions, such as conversation compaction, `CLAUDE.md` generation, session title generation, etc. featuring their own systems prompts. The result—500+ strings that are constantly changing and moving within a very large minified JS file. > [!important] > Want to **modify a particular piece of the system prompt** in your own Claude Code installation? **Use [tweakcc](https://github.com/Piebald-AI/tweakcc).** It— > - lets you customize the individual pieces of the system prompt as markdown files, and then > - patches your npm-based or native (binary) Claude Code installation with them, and also > - provides diffing and conflict management for when both you and Anthropic have conflicting modifications to the same prompt file. ## Extraction This repository contains the system prompts extracted using a script from the latest npm version of Claude Code. As they're extracted directly from Claude Code's compiled source code, they're guaranteed to be exactly what Claude Code uses. If you use [tweakcc](https://github.com/Piebald-AI/tweakcc) to customize the system prompts, it works in a similar way—it patches the exact same strings in your local installation as are extracted into this repository. ## Prompts Note that some prompts contain interpolated bits such as builtin tool name references, lists of available sub agents, and various other context-specific variables, so the actual counts in a particular Claude Code session will differ slightly—likely not beyond ±20 tokens, however. ### Agent Prompts Sub-agents and utilities. #### Sub-agents -
