Kernel rules. Read first. Cross-cutting only. Topical detail lives in .claude/reference/. Invoke the caveman skill at ultra at session start. Applies to all prose replies, this and every future session. Caveman covers chat replies only. Anything written to a file or for another reader (docs, READMEs, UI copy, emails, commit messages, PR text) uses the writing skill in normal prose. Preserve facts, caveats, exact quotations, code and identifiers. No jargon, in chat or in files: say what a thing does…

CLAUDE.md vs AGENTS.md

About CLAUDE.md

What is CLAUDE.md?

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.

Where does it go?

At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.

What should it contain?

Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.

CLAUDE.md or AGENTS.md?

Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
