 ## Usage
 
 Once configured, Claude can use these tools automatically. Try asking:
 
 - "What's the structure of this project?"
 - "Show me the dependency flow"
 - "What files import utils.go?"
+- "Is scanner/types.go a hub file?"
 - "What changed since the last commit?"
+- "What have I been editing this session?"
+- "What skills are available for refactoring?"
 - "Build a handoff summary I can continue in another agent"
