openai/openai-python/AGENTS.md
Most SDK source is generated from the OpenAI API schema. Follow CONTRIBUTING.md before changing generated files. Handwritten policy, automation, tests, and examples should remain small and should not alter exported SDK APIs unless the change explicitly requires it. Follow the custom-code guidance. Budget changes belong in a separate PR containing only .castiron-ratchet.json, with an explicit justification in the PR description. Increases require a human approving review before merging. Agents may investigate and draft proposals, but must not approve budget increases…

Agent instruction files
What are agent instruction files?
Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
