AGENTS.md — Open Format Standard for AI Coding Agent Instructions
About AGENTS.md
AGENTS.md is an open format standard for documenting instructions that AI coding agents need to work on software projects. Think of it as a README for agents — a dedicated, predictable place for setup commands, code style, testing instructions, and project conventions. Stewarded by the Agentic AI Foundation under the Linux Foundation, it is used by 60,000+ open-source projects.
