AGENTS.md Generator — FAQ

AGENTS.md is a tool-agnostic markdown file that gives coding agents (Cursor, Claude Code, OpenAI Codex, GitHub Copilot, and others) the rules of a project. Placed at the repository root, it is read before the agent writes code and covers setup, build and test commands, code style, project structure, commit conventions, and security. It is an operating manual for agents, not a README for humans.

Coding agents that support the AGENTS.md convention read it directly. For tools that use their own filename, this generator also outputs the same content as CLAUDE.md (Claude Code), .cursorrules (Cursor), and .github/copilot-instructions.md (GitHub Copilot), so the same rules apply regardless of which tool your team uses.

No. All generation happens in your browser. Your inputs are stored only in localStorage and, if you copy a share link, in the URL token (?s=). Nothing is uploaded to a server or crawled, so it is safe to use even with details about a private, internal codebase.

This generator renders the same content into each format. When rules change, either regenerate all four files, or keep AGENTS.md as the single source of truth and symlink the rest — for example, ln -s AGENTS.md CLAUDE.md. That way you maintain only one file.

Presets for Node.js/TypeScript, React/Vite, Python, Go, Rust, and Monorepo (pnpm/Turborepo). Choosing a preset auto-fills the install, build, test, and lint commands and the code style with each ecosystem’s conventions, which you can then edit to fit your project.

It is completely free with no sign-up. Nothing is collected beyond ads and basic analytics. Just fill the form and copy or download your rules file — no login required, and no usage limits.

Use the copy button next to the preview to put it on your clipboard, or the download button to save the file. The "copy config link" button at the top encodes your current form state into a share link (?s=) so you can share the setup with teammates or bookmark it.
