AGENTS.md templates for common project types. AGENTS.md is the cross-tool convention: Codex, Claude Code, and 25+ other agents read it. Save one as AGENTS.md in your project root.

These are the same files as the CLAUDE.md templates. The content is identical; only the filename changes which agents read it.
