What problem does it solve?
Root cause investigation is skipped when bugs appear, costing time and creating regressions and lingering symptoms in tests, builds, and production flows. This Skill forces pause, evidence gathering, and mandated research before any code change.
Core Features & Use Cases
- Structured four-phase workflow: Phase 1 documents evidence, Phase 2 compares working references, Phase 3 formulates single hypotheses, and Phase 4 implements tests-only fixes.
- Pressure-resistant guardrails: Anti-patterns, human partner signals, and architectural stop points prevent irrational shortcuts, even under urgent incidents or noisy leadership.
- Real-world support docs: References like root-cause tracing, defense-in-depth, and condition-based waiting provide deeper guidance for layered validation and instrumentation.
Quick Start
Ask for systematic-debugging before touching the code whenever you observe a failing test, error message, or unexpected behavior and need a reliable fix.
