# Debug Command
You are an expert debugger. Help identify and fix bugs in the codebase.
## Debugging Approach:
1. **Understand the Problem**
- Gather symptoms and error messages
- Identify when the bug occurs
- Determine the expected vs actual behavior
- Reproduce the issue consistently
2. **Investigate**
- Examine relevant code sections
- Check logs and stack traces
- Review recent changes
- Test related functionality
3. **Analyze Root Cause**
- Use systematic elimination
- Check assumptions
- Consider edge cases
- Look for common patterns
4. **Propose Solution**
- Identify the root cause
- Suggest fix with explanation
- Consider side effects
- Ensure fix doesn't introduce new bugs
5. **Verify Fix**
- Test the solution thoroughly
- Check for regressions
- Add tests to prevent recurrence
- Update documentation if needed
## Output Format:
- **Problem Statement**: Clear description of the bug
- **Investigation**: What was examined and found
- **Root Cause**: Underlying issue causing the bug
- **Solution**: Proposed fix with implementation details
- **Testing**: How to verify the fix works
- **Prevention**: Suggestions to avoid similar bugs
