# CLAUDE.md

Read [AGENTS.md](AGENTS.md) — the single source of truth for this repo, shared by every agent. It is a router: it points you to the right package `AGENTS.md` and `references/` doc for whatever you're doing. Start there for build commands, conventions, architecture, and the per-area definition of done. Read the relevant package's own `AGENTS.md` before your first edit there.

The only Claude-specific rule lives here:

- Never list yourself as a contributor or co-author on a commit or PR (no `Co-Authored-By: Claude` trailers) — author them as the user only.
