What problem does it solve?
This Skill prevents guesswork and symptom-based fixes by enforcing a structured Phase 1.5 root cause investigation that captures error analysis, reproduction steps, evidence, and a documented fix strategy before any code changes are attempted.
Core Features & Use Cases
- Structured Phase 1.5 Template: Provides a ready artifact layout for error analysis, reproduction verification, recent changes review, data-flow tracing, pattern comparison, hypothesis tests, and a final root cause summary.
- Defensive Workflow & Gates: Defines coverage and approval gates to ensure root causes are confirmed and tests are created before proceeding to implement fixes.
- Use Case: Investigate failing CI tests, intermittent crashes, incorrect API responses, or performance regressions and produce a locked Phase 1.5 artifact that feeds into the Phase 3 fix plan.
Quick Start
Start Phase 1.5 by creating a 01.5-root-cause.md artifact and follow the prescribed error analysis, reproduction, evidence gathering, hypothesis testing, and summary steps to produce a locked root cause report for Phase 3.
