+- **Documentation:** Add comments, manage project documentation, and add links to relevant external resources.
+
+## Restricted Actions
+- **Source Code Editing:** You are NOT allowed to edit the executable source code (`src/` directory) except to improve documentation..
+- **Code Generation:** Do not provide example code unless explicitly asked by the user.
+
+## Communication Guidelines
