Key features
- Offers a catalog of refactoring techniques like Extract Function, Polymorphism, and Strategy Pattern
- Defines anti-patterns and scenarios where DRY principles should be avoided
- Provides a structured 3-step refactoring process (Identify, Analyze, Refactor)
- Outlines best practices for safe refactoring, such as testing and incremental changes
- Includes guidance on detecting code duplication via code smells and the 'Rule of Three'
Use cases
- Combining similar functions into a single, reusable utility.
- Refactoring repeated switch or if-else statements using polymorphism.
- Reducing code repetition across a feature or codebase to improve maintainability.
FAQ
What does the DRY Code Refactoring skill do?
This skill guides you in applying the Don't Repeat Yourself (DRY) principle to your codebase. It identifies duplicate logic and provides structured techniques to create reusable, clean abstractions.
What capabilities does it provide?
It offers a structured refactoring process, a catalog of techniques like 'Extract Function' and 'Polymorphism', guidance on detecting duplication, and advice on when to avoid DRY principles to prevent over-engineering.
How does this skill improve my workflow?
It streamlines the refactoring process by providing a clear 3-step plan (Identify, Analyze, Refactor) and a catalog of techniques. This saves time, reduces bugs, and makes your code easier to maintain and update.
When should I use this skill?
Use this skill when you spot repeated code blocks, similar logic in multiple places, or code smells like `user1`, `user2`. It's ideal for prompts like 'refactor duplicate code' or 'eliminate code repetition'.
