Learn to debug CI failures by identifying unexpected routing changes, not just code breaks
Action Steps
- Run a diff to identify changes in the codebase
- Analyze the CI failure to determine the failing surface
- Investigate routing changes that may have caused the failure
- Use tools like POSIX and langgraph to help identify routing issues
- Test and verify the fix to ensure the CI pipeline is green again
