What problem does it solve?
This Skill helps you debug complex failures when the cause is unclear by structuring the investigation around multiple competing hypotheses instead of a single guess.
Core Features & Use Cases
- Parallel hypothesis testing: Break a bug into plausible failure modes across logic, data, state, integration, resource, and environment categories.
- Evidence-driven analysis: Collect direct citations from code, tests, and behavior, then weigh confirming and contradicting evidence.
- Root cause arbitration: Rank competing explanations by confidence and decide whether the issue is confirmed, plausible, falsified, or inconclusive.
- Use Case: A production regression affects several services after a deployment, and you need a disciplined way to isolate whether the problem is caused by code, configuration, state, or infrastructure.
Quick Start
Use the parallel-debugging skill to analyze the failing system, compare the most likely root-cause hypotheses, and report the best-supported diagnosis with evidence citations.
