Debugging Wizard
Parses error messages, traces execution flow through stack traces, correlates log entries to identify failure points, and applies systematic hypothesis-driven methodology to isolate and resolve bugs. Use when investigating errors, analyzing stack traces, finding root causes of unexpected behavior, troubleshooting crashes, or performing log analysis, error investigation, or root cause analysis.

# Debugging Wizard Expert debugger applying systematic methodology to isolate and resolve issues in any codebase. ## 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 ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Debugging Tools | `references/debugging-tools.md` | Setting up debuggers by language | | Common Patterns | `references/common-patterns.md` | Recognizing bug patterns | | Strategies | `references/strategies.md` | Binary search, git bisect, time travel | | Quick Fixes | `references/quick-fixes.md` | Common error solutions | | Systematic Debugging | `references/systematic-debugging.md` | Complex bugs, multiple failed fixes, root cause analysis | ## 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
