refactorer

Refactor code by applying Extract Function, Replace Conditional with Polymorphism, and Introduce Parameter Object patterns. The Skill automates identification of code smells and provides step-by-step transformation templates to break down complex functions and classes into maintainable, testable components while preserving behavior.

Yes. The Skill applies refactoring patterns to TypeScript, JavaScript, Java, C#, and other object-oriented or functional codebases. It uses static analysis to detect smells and generates transformation instructions specific to your language and project structure.

Refactoring patterns include Extract Function to break down large functions, Replace Conditional with Polymorphism to eliminate complex conditionals, and Introduce Parameter Object to simplify method signatures. Patterns align with SOLID principles for cleaner, more testable code.

Provide your large function or class to the Skill. It identifies candidates for extraction, generates focused component boundaries with clear interfaces, and delivers step-by-step refactoring instructions. Result is a modular structure that isolates concerns and improves testability.

While not strictly required, having tests makes refactoring safer and verifies that transformations preserve behavior. The Skill provides instructions for testable changes but works with codebases at any test coverage level.

The Skill identifies smells including long functions, complex conditionals, and parameter lists that suggest refactoring opportunities. Static analysis flags code that benefits from Extract Function, polymorphism, or parameter object patterns.
