Solution Implementation: Provide working fixes with clear explanations

Prevention Strategies: Suggest defensive programming techniques to avoid similar issues

Debugging Workflow

Copy this checklist and track your progress:

Debugging Progress:
- [ ] Step 1: Reproduce and understand the error
- [ ] Step 2: Locate problematic code using search tools
- [ ] Step 3: Analyze code flow and identify root cause
- [ ] Step 4: Implement and test the fix
- [ ] Step 5: Verify solution and suggest prevention

Step 1: Reproduce and understand the error

Examine error messages, stack traces, and logs. Understand:

• What was the expected behavior?
• What actually happened?
• When and where did it occur?
• What conditions triggered it?

Step 2: Locate problematic code

Use search tools strategically:

• Grep: Find error messages or exception types
• Glob: Search for related files
• Read: Examine suspect code sections
• Bash: Run diagnostic commands

Step 3: Analyze root cause

Apply systematic analysis:

• Check for null/undefined references
• Verify type compatibility and casting
• Examine async/await patterns and promises
• Look for race conditions and concurrency issues
• Review dependency versions and compatibility

Step 4: Implement fix

Provide solution that:

• Addresses root cause, not symptoms
• Follows existing code patterns
• Includes appropriate error handling
• Maintains backward compatibility

Step 5: Verify and prevent

• Test the fix thoroughly
• Suggest unit tests to catch regression
• Recommend defensive programming practices
• Document the issue and resolution

Best Practices

Systematic Approach:

• Use divide and conquer to isolate issues
• Test hypotheses with minimal reproducible cases
• Document findings and solutions

Common Pitfalls to Check:

• Null/undefined checks and optional chaining
• Type errors and incorrect type assertions
• Missing error boundaries and exception handling
• Resource leaks (connections, file handles)
• Performance bottlenecks (N+1 queries, inefficient loops)

Code Quality:

• Provide clear explanations for reasoning
• Suggest refactoring opportunities
• Recommend testing strategies
• Promote defensive programming techniques

Automatic Triggers

This skill activates when:

• Errors or exceptions are reported
• Tests fail during execution
• Performance degrades unexpectedly
• Code crashes or hangs
• User explicitly requests debugging help
