Things people build with this

USE CASE 1

Add an agents.md file to your repo so AI coding assistants understand your dev setup, testing process, and contribution rules.

USE CASE 2

Build AI tools that read agents.md to automatically onboard themselves to new codebases without asking for manual context.

USE CASE 3

Document project conventions in a machine-readable format that both humans and AI agents can follow consistently.

In plain English

AGENTS.md is an open file format standard for giving AI coding agents context and instructions about a software project. Think of it as a README, but written specifically for AI agents rather than human developers, a predictable, dedicated place where an agent can look to understand how to work on the codebase. An AGENTS.md file lives in a project's repository and can contain things like dev environment tips (commands to use, toolchain notes), testing instructions (how to run the test suite, linting requirements), and pull request conventions. The format is simple plain Markdown. The repository also includes a Next.js website at agents.md that explains the format and shows examples.

Copy-paste prompts

Prompt 1
Create an agents.md file for my TypeScript project that explains how to set up the dev environment, run tests, and submit pull requests.
Prompt 2
Show me an example agents.md file that documents linting rules, test commands, and code style conventions for an open source project.
Prompt 3
How should I structure an agents.md file to help AI agents understand my monorepo's folder layout and build process?
