CLAUDE.md vs AGENTS.md

About AGENTS.md

What is AGENTS.md?

An open format for instructions to coding agents, read by Codex, Cursor and others. Think of it as a README written for agents.

Where does it go?

At the repository root, with more specific files in subdirectories. Agents read the one closest to the file they're editing.

Setup and test commands, code style, and the rules a new contributor would need to know.

Claude Code reads CLAUDE.md. A one-line CLAUDE.md that points at AGENTS.md covers both.
