AGENTS.md for Codex

Codex reads an AGENTS.md file before it touches your code. It is the same idea as CLAUDE.md: a plain Markdown file that tells the agent how your project works. AGENTS.md started with Codex and is now an open format many agents read.

Layering

Codex builds an instruction chain when it starts, reading files from broad to specific. That means you can keep global preferences in one place and repo-specific rules in another, and the closer-to-the-code file wins on conflicts.
