AGENTS.md, CLAUDE.md and Cursor rules, from one form.

Write your project’s rules once and get the file each coding agent reads: CLAUDE.md for Claude Code, AGENTS.md for Codex, and a rules file for Cursor. It runs in your browser, and an AI assist can fill the form for you from your package.json or README.

AI assistPaste your package.json or README, or describe the project. The AI fills the form; you check it.

What you paste is sent to our AI model to fill the form, and is not stored.

How agents should work here

Keep changes small and focused; one concern per change.Add or update tests with every behaviour change, and run them before saying a task is done.Read the surrounding code first and match its style, naming and patterns.Do not add a new dependency without asking.Ask before changing database schemas, migrations or public APIs.Never commit secrets, keys or .env files; never print them in output.End each task with a short summary of what changed and why.

## How to work here

- Keep changes small and focused; one concern per change.
- Add or update tests with every behaviour change, and run them before saying a task is done.
- Read the surrounding code first and match its style, naming and patterns.
- Do not add a new dependency without asking.
- Never commit secrets, keys or .env files; never print them in output.

Save as CLAUDE.md in the root of your repository. Claude Code reads it at the start of every session.
