Refactoring Workflow

Step 1: Analyze Code and Identify Issues

Examine the codebase to identify code smells and quality issues:

• Long methods (>20-30 lines) or large classes (>300-500 lines)
• Duplicated code blocks or similar logic in multiple places
• Unclear or misleading names for variables, methods, or classes
• Complex conditional logic or deeply nested structures
• Poor separation of concerns or tight coupling between components
