agents.md

Open Markdown format for giving coding agents project instructions

24.9k starsMITlast commit Sep 2026

AGENTS.md is a specification for a plain Markdown file kept in a repo that holds dev environment, testing and PR instructions for AI coding agents. The repository also contains the Next.js site served at agents.md, which explains the format and lists examples. It has no runtime or agent code.

Strengths

  • Plain Markdown, no tooling, schema or dependencies required
  • One predictable file location for agent instructions, separate from the human README
  • Website runs locally with pnpm install and pnpm run dev

Weaknesses

  • No enforced schema; README shows only a minimal example
  • Repo holds the website and spec, not a tool or agent
  • README does not list which agents read the file
  • No releases published
  • no GPU
  • Needs Node.js, pnpm
  • port 3000
