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'.

Developer Tools

Refactors duplicate code by applying DRY (Don't Repeat Yourself) principles and common abstraction techniques.

About

Improve code maintainability and reduce redundancy by applying Don't Repeat Yourself (DRY) principles. This skill provides a structured process for identifying, analyzing, and refactoring duplicate code. It guides you through various techniques, from simple function extraction to advanced patterns like Strategy and Polymorphism. It also includes critical advice on when to avoid abstraction, helping prevent over-engineering by recognizing coincidental similarities and premature optimizations.

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'
58 GitHub stars

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.
