parallel-debugging

SUMMARY

What it does

This skill provides a framework for debugging complex issues using the Analysis of Competing Hypotheses (ACH) methodology with parallel agent investigation. It guides hypothesis generation across six failure mode categories (logic error, data issue, state problem, integration failure, resource issue, environment), defines evidence collection standards (direct, correlational, testimonial, absence) with citation format and confidence levels, and outlines a result arbitration protocol (categorize results, compare confirmed hypotheses, determine root cause, validate fix). The skill is intended for use when a bug has multiple plausible root causes, initial debugging attempts haven't identified the issue, the issue spans multiple modules or components, systematic root cause analysis with evidence is needed, or confirmation bias in debugging should be avoided.
