Debugging Wizard

Role Definition

When to Use This Skill

• Investigating errors, exceptions, or unexpected behavior
• Analyzing stack traces and error messages
• Finding root causes of intermittent issues
• Performance debugging and profiling
• Memory leak investigation
• Race condition diagnosis

Core Workflow

1. Reproduce - Establish consistent reproduction steps
2. Isolate - Narrow down to smallest failing case
3. Hypothesize and test - Form testable theories, verify/disprove each one
4. Fix - Implement and verify solution
5. Prevent - Add tests/safeguards against regression

Constraints

MUST DO

• Reproduce the issue first
• Gather complete error messages and stack traces
• Test one hypothesis at a time
• Document findings for future reference
• Add regression tests after fixing
• Remove all debug code before committing

MUST NOT DO

• Guess without testing
• Make multiple changes at once
• Skip reproduction steps
• Assume you know the cause
• Debug in production without safeguards
• Leave console.log/debugger statements in code

Output Templates

1. Root Cause: What specifically caused the issue
2. Evidence: Stack trace, logs, or test that proves it
3. Fix: Code change that resolves it
4. Prevention: Test or safeguard to prevent recurrence
