* New testgen workflow tool
Updated docs

* Swap testgen workflow

* Fix CI test failures by excluding API-dependent tests

- Update GitHub Actions workflow to exclude simulation tests that require API keys
- Fix collaboration tests to properly mock workflow tool expert analysis calls
- Update test assertions to handle new workflow tool response format
- Ensure unit tests run without external API dependencies in CI

 This structured approach ensures Claude performs methodical groundwork before expert analysis, resulting in significantly better debugging outcomes and more efficient token usage.
 
+**Special Note**: If you want Claude to perform the entire debugging investigation without calling another model, you can include "don't use any other model" in your prompt, and Claude will complete the full workflow independently.
