About

AGENTS.md is a plain Markdown file convention for giving AI coding agents project-specific context: build steps, test commands, code style and PR conventions. It sits alongside README.md, which stays aimed at human contributors. The format has no required fields, and a repository can use nested AGENTS.md files for subprojects in a monorepo.

The format came out of collaboration between OpenAI Codex, Amp, Jules from Google, Cursor and Factory. The site says it is used by over 60k open-source projects and is now stewarded by the Agentic AI Foundation under the Linux Foundation. Typical sections are project overview, build and test commands, code style, testing instructions and security considerations.

It is read by a growing set of coding agents and tools. Some tools need configuration to pick it up, for example read: AGENTS.md in Aider's .aider.conf.yml or a context.fileName setting in Gemini CLI. According to a YouTube creator, Claude Code uses CLAUDE.md instead, so projects often symlink or rename files for compatibility. The site suggests ln -s AGENTS.md AGENT.md for migrating older files. It is a file convention, not software, and how an agent follows the instructions depends on the agent.
