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
