parallel-debugging
Debug complex issues using competing hypotheses with parallel investigation, evidence collection, and root cause arbitration. Use this skill when debugging bugs with multiple potential causes, performing root cause analysis, or organizing parallel investigation workflows.

Same command for any agent — swap --agent for codex, cursor, copilot.

# 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 - Invalid or unexpected input data - Type mismatch or coercion error - Null/undefined/None where value expected - Encoding or serialization problem - Data truncation or overflow ### 3. State Problem - Race condition between concurrent operations - Stale cache returning outdated data - Incorrect initialization or default values - Unintended mutation of shared state - State machine transition error ### 4. Integration Failure - API contract violation (request/response mismatc

What does the parallel-debugging skill do?
Debug complex issues using competing hypotheses with parallel investigation, evidence collection, and root cause arbitration. Use this skill when debugging bugs with multiple potential causes, performing root cause analysis, or organizing parallel investigation workflows.
How do I install it?
Run `npx skills add wshobson/agents --skill parallel-debugging --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From wshobson/agents, a repository with 38,479 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
