Why we included this project

Anyone who tunes Claude Code by editing its system prompt needs a reliable map of what actually ships in each release, and this repository is that map. It extracts every part of Claude Code's prompt layer straight from the compiled npm package: the builtin tool descriptions, the Plan/Explore/Task subagent prompts, and the utility prompts behind compaction, CLAUDE.md generation, statusline setup, and code review. Each entry shows its token count, which helps you judge where the model's attention budget goes, and the changelog tracks how these strings shift from version to version. That makes it a solid reference while you patch your own install, and for teams building their own coding agents the subagent and tool-description prompts are a useful starting point for design patterns worth borrowing.
