+            2. Think carefully and try to understand the root cause. If the issue is unclear or not well defined, ask me to clarify and provide more information.
+            3. Write a proposed implementation plan to PLAN.md for me to review before starting implementation. Your plan should use TDD and only make the minimal changes necessary to fix the root cause.
+            4. When I approve your plan, start working on it. If you encounter issues with the plan, ask me for clarification and update the plan as required.
+            5. When you have finished implementation according to the plan, commit and push your changes, and create a PR using the gh CLI for me to review.
