How does it handle complex conditional logic?

It utilizes techniques such as introducing guard clauses for early returns and replacing large switch statements with polymorphism to make logic more modular.

Does this skill change the behavior of my code?

No, the primary goal of refactoring with this skill is to improve the internal structure of the code while strictly preserving its external behavior and functionality.

What types of 'code smells' can this skill identify?

It specifically targets long methods, deeply nested conditionals (arrow code), primitive obsession, magic numbers, and feature envy.

Can I use this skill on legacy code that doesn't have tests?

While the skill provides patterns for legacy code, it follows a safety-first principle recommending that tests be established before refactoring to ensure no regressions occur.

Improves software maintainability and readability by applying industry-standard refactoring patterns and techniques to legacy or complex codebases.

Acerca de

The Code Refactoring skill provides Claude with a comprehensive framework for identifying 'code smells' and implementing structural improvements without altering external behavior. It enables the transformation of monolithic methods, deeply nested conditionals, and primitive-heavy logic into clean, modular, and object-oriented code. By following a safe, test-driven refactoring process, this skill helps developers reduce technical debt, simplify complex logic through patterns like polymorphism and extraction, and ultimately create more scalable and maintainable applications.
