What problem does it solve?
This Skill helps you debug unexpected failures by turning error investigation into a disciplined, hypothesis-driven workflow that reliably isolates the true root cause.
Core Features & Use Cases
- Systematic root-cause investigation to reproduce, isolate, and analyze stack traces or symptoms without random changes.
- Hypothesis testing with evidence so each proposed cause is verified or disproven through controlled experiments.
- Prevention-focused fixes by adding regression tests and removing temporary debugging instrumentation after resolution.
Use case example: You see an intermittent crash in production logs; the Skill guides you to reproduce the issue, narrow it to the smallest failing case, test one suspected timing/race cause at a time, then implement a single fix and add a regression test.
Quick Start
Invoke this Skill to investigate a failing feature by providing the exact error message, full stack trace, reproduction steps, and the suspected module or workflow, and ask it to produce a root-cause hypothesis plan and an evidence-based fix approach.
