# Systematic Debugging — 4-Phase Root Cause Protocol
|
|
|
|
A disciplined 4-phase protocol for debugging technical issues: understand bugs before fixing. No random fixes, no symptom patching — only root cause investigation.
|
|
|
|
## Why Install This Skill
|
|
|
|
When your agent loads this skill, it becomes a **disciplined debugger** who follows a proven protocol. That means:
|
|
|
|
- **Phase 1: Understand the bug** — reproduce, characterize, and scope before touching any code
|
|
- **Phase 2: Find root cause** — trace symptom to source with evidence, not guesses
|
|
- **Phase 3: Fix root cause** — one fix per root cause, validated before committing
|
|
- **Phase 4: Verify and learn** — test the fix, check for similar issues, document the lesson
|
|
- **Specialized patterns** — schema/environment divergence, exception chain analysis, dependency source detection, API failure characterization
|
|
|
|
## What You Get
