# Debug Incident Prompt Walk through the 4-phase debugging process: ## Phase 1: Reproduce - What are the exact steps to reproduce? - What environment (OS, versions, config)? - What is the exact error message/output? ## Phase 2: Investigate - What does the stack trace tell us? - What changed recently that could have caused this? - What logs are relevant? - Can we isolate the failing component? ## Phase 3: Fix - What is the root cause? (not the symptom) - What is the minimal fix? - Does this fix address the root cause permanently? - Could this fix introduce regressions? ## Phase 4: Verify - Does the fix resolve the original issue? - Do existing tests still pass? - Should we add a regression test? If 3 fix attempts fail, trigger architectural review.
