Top-level workflow controller that manages phase transitions.
Understand the bug report and propose a plan before taking action.
Perform systematic root cause analysis to identify the underlying issue causing a bug
Create comprehensive documentation for a bug fix including issue updates, release notes, and team communication
Implement a bug fix based on root cause analysis, following project best practices
Create a pull request from the current branch. Use this instead of running gh pr create directly — it detects GitHub App vs user auth, finds or creates forks, syncs workflow files, detects the upstream default branch, and falls back to compare URLs when API access is limited.
Systematically reproduce a reported bug and document its observable behavior
Critically evaluate a bug fix and its tests, then recommend next steps.
