From the README
We've released Piebald, the ultimate agentic AI developer experience.
Download it and try it out for free! https://piebald.ai/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 v2.1.202 (July 6th, 2026). It also contains a CHANGELOG.md for the system prompts across 228 versions since v2.0.14. From the team behind Piebald.
This repository is updated within minutes of each Claude Code release. See the changelog, and follow @PiebaldAI on X for a summary of the system prompt changes in each release.
Why multiple "system prompts?"
Claude Code doesn't just have one single string for its system prompt.
The result—500+ strings that are constantly changing and moving within a very large minified JS file.
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 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.
