Code Refactor Analyzer

Code Refactor Analyzer

This skill helps developers identify code that needs refactoring based on new requirements, generates actionable todo lists, and tracks completion progress.

Capabilities

• Requirement Analysis: Understand user requirements and identify potential code impacts
• Code Impact Analysis: Analyze repository to find code lines that may be affected by the requirement
• Todo Report Generation: Create structured todo lists with specific code locations and tasks
• Completion Validation: Check if previously generated todo items have been completed
• State Management: Automatically detects if this is the first use (generate report) or subsequent use (check completion)

Input Requirements

• User Requirement: Description of the new feature, change, or refactoring need
• Repository Context: Claude Code should have access to the codebase (via open repository)
• Optional Parameters:
  • Specific file paths to focus on
  • Priority levels for tasks
  • Deadline constraints

Output Formats

• First Use: Generates a todo report file at .claude/code_refactor_report/[requirement]-[date].md
• Subsequent Use: Provides completion validation report showing:
  • Completed items (checked off)
  • Pending items
  • New items that may have been added
• Interactive Guidance: Step-by-step suggestions for refactoring

How to Use

"Analyze the codebase for implementing user authentication and identify what needs to be refactored" "Check if the todo items from yesterday's refactoring plan have been completed" "Generate a refactoring plan for migrating from class-based components to functional components"

Scripts

• code_analyzer.py: Main analysis engine that identifies impacted code
• report_manager.py: Handles todo report generation and completion validation
• state_manager.py: Manages skill state (first use vs subsequent use)

Best Practices

1. Clear Requirements: Provide specific, detailed requirements for better analysis
2. Repository Access: Ensure Claude has access to the codebase before using this skill
3. Incremental Refactoring: Focus on small, manageable sections rather than entire codebase
4. Regular Validation: Use the completion check feature regularly to track progress
5. Documentation: Add comments to refactored code explaining the changes

Limitations

• Requires Claude to have access to the repository files
• Analysis is based on code patterns and may not catch all edge cases
• Cannot automatically fix code - provides guidance only
• Works best with well-structured codebases
• May produce false positives for complex refactoring scenarios
