Bug Fix Workflow
Systematic process for fixing bugs properly.
Phase 1: Root Cause Analysis
Agents: root-cause-analyst
Methods:
- Error trace analysis
- Log investigation
- State inspection
- Reproduce the bug consistently
Output: Root cause, affected components, impact assessment
Phase 2: Fix Implementation
Constraints:
- Minimal scope (fix the bug, nothing more)
- Backward compatible
- Well tested
Phase 3: Code Review
Agents: code-reviewer
Focus:
- Fix correctness
- Side effects
- Edge cases
Phase 4: Regression Testing
Agents: test-automator
Create tests:
- Regression test (prevents this bug from returning)
- Edge case tests
- Integration tests if affected
Phase 5: Security Check
Agents: security-auditor
Blocking: Ensure fix doesn't introduce vulnerabilities
Phase 6: Validation
Agents: quality-engineer
Checklist:
- Original issue resolved
- No new issues introduced
- All tests pass
Phase 7: Documentation
Agents: technical-writer
- Changelog entry
- Incident report (for significant bugs)
- Prevention guide (what caused it, how to avoid)
Phase 8: Deployment
Agents: deployment-engineer
Strategy: Hotfix if critical, normal release otherwise
Monitor for 24h:
- Error rate
- Performance metrics
- User reports
Success Criteria
- Bug verified fixed
- Regression tests added
- No side effects
- Documentation updated
Anti-patterns
- ❌ Fixing symptoms instead of root cause
- ❌ Large scope changes mixed with bug fix
- ❌ Skipping regression tests
- ❌ No documentation of what caused it
