What problem does it solve?
This Skill helps diagnose software failures from error messages, stack traces, logs, or reproducible bad behavior. It focuses on identifying the real root cause so you can fix the issue instead of masking it.
Core Features & Use Cases
- Root-cause analysis: Turns vague failures into a precise symptom, likely cause, and supporting evidence.
- Minimal verification: Suggests the cheapest test to distinguish between competing hypotheses.
- Concrete fixes: Recommends a specific code change and a follow-up verification step, usually a failing test.
- Use case: A test suddenly starts failing after a refactor; this Skill helps determine whether the problem is null data, off-by-one logic, stale state, environment mismatch, or another common failure pattern.
Quick Start
Ask the debugger skill to analyze the error message, relevant code, and reproduction steps, then provide the likely root cause and the smallest test that confirms it.
