name: debugging description: Systematic debugging of code to find root causes, fix bugs, and prevent regressions. Use whenever an error, bug, or unexpected behavior appears.

Debugging Skill

When debugging code, follow this strict process:

Debugging Checklist

1. Understand the bug

   • What is the expected behavior?
   • What actually happens?
   • Is the bug reproducible?

2. Locate the source

   • Identify the exact file, function, or component
   • Check recent changes related to the issue

3. Analyze the cause

   • Logic errors
   • State issues
   • Async / timing problems
   • Edge cases or missing validations

4. Fix with minimal change

   • Do not refactor unless necessary
   • Keep the fix scoped and safe

5. Prevent regression

   • Add or update tests if applicable
   • Mention similar areas that could break

How to respond

• Explain the root cause clearly
• Show the exact code change needed
• Warn if the issue can appear again elsewhere
• Prefer simple and predictable fixes
