Coding agents work better when they know how your project runs. Pick your stack and toolchain, set a few rules, and download a ready CLAUDE.md or AGENTS.md.

This is an interactive tool. Use it at https://promptitin.com/free-tools/claude-md-generator.

## How to use it

1. Pick CLAUDE.md for Claude Code, or AGENTS.md for Codex, Cursor and other agents.
2. Write the project name and what it does, and tap your stack.
3. Pick your package manager to fill in the commands, then edit them to match.
4. Choose your house rules, download the file and save it in the root of your repo.

## Tips

- The commands matter most. An agent that knows how to build and test can check its own work.
- Keep it short. Every line is read in every session, so cut anything the agent would do anyway.
- Add a rule each time the agent repeats a mistake.
- Using both? Keep AGENTS.md as the main file and point CLAUDE.md to it.

## FAQ

### What is CLAUDE.md?

A Markdown file Claude Code reads at the start of every session. It holds your project's commands, conventions and rules, so you don't repeat them in every chat.

### What is AGENTS.md?

An open format for the same idea, read by many coding agents, including OpenAI Codex and Cursor. It lives in the root of your repo.

### Which one should I use?

CLAUDE.md if you use Claude Code. AGENTS.md if you use Codex, Cursor or several agents. The content is the same, so you can make both here.

### Is my project info sent anywhere?

No. The file is put together in your browser.
