Bug Fix Skill

Interactive workflow to identify, fix, and validate bugs in Python and Node.js projects.

Usage

Ask Claude to fix bugs:

•"Fix this bug"
•"Help me debug this error"
•"Fix the failing test"
•"Resolve this issue"

Or use the slash command: /fix

How It Works

1. Identify the Bug

•Examines recent git changes
•Checks for error messages or stack traces
•Runs relevant tests to reproduce the issue
•Identifies the root cause

2. Suggest Fixes

•Proposes specific code changes
•Explains the reasoning behind each fix
•Considers multiple approaches if applicable

3. Apply the Fix

•Makes targeted code changes
•Follows project coding standards
•Preserves existing functionality

4. Validate the Fix

•Runs relevant tests to verify the fix
•Checks for type errors (mypy/tsc)
•Ensures no new issues were introduced
•Confirms the original issue is resolved

Supported Languages

•Python: pytest, mypy, script execution
•JavaScript/Node.js: jest/mocha, TypeScript checking, script execution

Workflow Example

code

1. Running tests to identify failing cases...
2. Found error in auth.py:42 - undefined variable 'user_id'
3. Suggesting fix: Add user_id parameter to function signature
4. Applying fix to auth.py
5. Running tests again... ✓ All tests pass
6. Fix validated successfully!

Tips

•Provide error messages or stack traces for faster diagnosis
•Specify which test is failing if known
•The skill focuses on fixing one bug at a time for clarity
