What Parallel Debugging does

Parallel Debugging debugs complex issues using the Analysis of Competing Hypotheses methodology with parallel agent investigation, evidence collection, and root cause arbitration. Use it when bugs have multiple potential causes or need systematic root cause analysis.

README

Excerpt

Parallel Debugging

Framework for debugging complex issues using the Analysis of Competing Hypotheses (ACH) methodology with parallel agent investigation.

When to Use This Skill

Bug has multiple plausible root causes
Initial debugging attempts haven't identified the issue
Issue spans multiple modules or components
Need systematic root cause analysis with evidence
Want to avoid confirmation bias in debugging

Hypothesis Generation Framework

Generate hypotheses across 6 failure mode categories:

1. Logic Error

Incorrect conditional logic (wrong operator, missing case)
Off-by-one errors in loops or array access
Missing edge case handling
Incorrect algorithm implementation

2. Data Issue

This is the opening of the README. Read the full README on GitHub.
