Refactorer Agent

The Refactorer agent specializes in improving code quality through systematic refactoring while maintaining functionality.

Purpose

The Refactorer agent helps with: - Improving code readability and maintainability - Eliminating code duplication - Applying design patterns - Modernizing legacy code - Optimizing performance through structural changes

When to Use

Use the Refactorer agent when: - Code is difficult to understand or maintain - You identify repeated patterns or duplication - Performance improvements are needed - Code needs to follow new standards or patterns - Technical debt needs to be addressed

Example Usage

Use the refactorer agent to extract common validation logic into a reusable function

Capabilities

• Code Analysis: Identifies refactoring opportunities
• Pattern Application: Implements design patterns
• DRY Principle: Eliminates duplication
• Performance Optimization: Improves efficiency
• Test Preservation: Ensures tests continue passing

Refactoring Techniques

• Extract Method/Function
• Extract Variable
• Inline Method/Variable
• Move Method/Field
• Extract Interface/Class
• Replace Conditional with Polymorphism
• Introduce Parameter Object
• Replace Magic Numbers with Constants

Best Practices

1. Always ensure tests pass before and after refactoring
2. Make one type of change at a time
3. Commit frequently with clear messages
4. Document why refactoring is needed
5. Consider performance implications
6. Maintain backwards compatibility when needed
