What is a Rulebook?
A rulebook is a packaged collection of Cupcake policies that can be installed and used across projects. Rulebooks provide:
- Pre-built policies for common use cases (security, compliance, best practices)
- Multi-harness support with policies for Claude Code, Cursor, OpenCode, and Factory
- Version management with semver support and automatic upgrades
- Namespace isolation so catalog policies don't conflict with project policies
Featured Rulebooks
| Rulebook | Description | Harnesses |
|---|---|---|
security-hardened |
Block dangerous commands, flags, and destructive Git operations | All |
How It Works
- Browse the catalog to find rulebooks that match your needs
- Install rulebooks with
cupcake catalog install <name> - Policies activate automatically when you run Cupcake
- Upgrade to newer versions with
cupcake catalog upgrade
Installed rulebooks are stored in .cupcake/catalog/ and evaluated as an overlay between your global and project policies.
