AGENTS.md

A project file that gives coding agents standing instructions about the repository and its conventions.

Illustrative conversation

  1. Where should we tell coding agents to run pnpm test before committing?
  2. Put that repository-wide instruction in AGENTS.md so agents can load it with the codebase.

Definition

AGENTS.md is a Markdown file placed in a repository to give coding agents durable project guidance. It can document setup commands, tests, code style, security constraints, and review expectations. Supporting tools can load nested files for more specific project guidance. Discovery and precedence depend on the harness; the file is neither automatically read by every model nor an execution-time security control.
