description	Refactor code for improved quality. Use this skill when the user runs /refactor or asks for this kind of task on a file or directory (e.g. "/refactor @./src/app.py").

/refactor

Refactor the provided code following these principles:

Code Quality

• Extract complex logic into well-named functions
• Use meaningful variable and function names
• Follow the Single Responsibility Principle
• Apply DRY (Don't Repeat Yourself)
• Reduce cyclomatic complexity

Modern Patterns

• Use modern language features appropriately:
  • Python: type hints, f-strings, dataclasses, match statements
  • JavaScript: async/await, destructuring, optional chaining
  • Java: records, pattern matching, var keyword
• Apply appropriate design patterns
• Use functional programming where it improves clarity

Error Handling

• Add proper exception handling
• Use specific exception types
• Provide meaningful error messages
• Implement graceful degradation where appropriate

Performance

• Identify and fix obvious performance issues
• Use appropriate data structures
• Avoid premature optimization

Output

Provide the refactored code with:

• Explanation of changes made
• Before/after comparison for significant changes
• Any trade-offs or considerations

Apply the above to the file(s) or directory the user referenced with @.
