What problem does it solve?
This Skill helps you perform disciplined root-cause debugging so you stop relying on guesswork and start producing evidence-backed explanations that prevent regressions.
Core Features & Use Cases
- Root-cause-first workflow: Establish the earliest divergence from expected behavior before proposing any changes.
- Evidence-driven investigation: Use differential analysis, regression hunting, and
file:line-style evidence to justify conclusions.
- Reproduction and verification loop: Build a reliable failing signal, minimize the failing case, then create/fix with a failing test and fresh verification.
- Structured debug reporting: Emit a consistent Debug Report (and optional postmortem) to communicate SYMPTOM, ROOT CAUSE, FIX, EVIDENCE, REGRESSION, RELATED, and STATUS.
Quick Start
Ask the skill to debug a broken test or failing CLI run by sharing the full error output and steps to reproduce, then follow it to produce a root-cause statement with evidence and a verified fix plan.
