 ### What happens behind the scenes?
 
-1. Copies the `.agent` directory (containing all rules and skills) to your project root.
-2. Automatically updates your `.gitignore` to prevent committing agent configurations.
-3. Sets up your environment for AI Agent interaction without poluting your `node_modules`.
