What types of code smells can this skill identify?

It identifies long functions, excessive parameters, duplicated logic, deep nesting, and poorly named variables or classes.

Can I add new features while refactoring with this skill?

No, this skill enforces a strict separation between refactoring and feature development to ensure each change is isolated and safe.

Does this skill change how my code works?

No, the primary rule of this skill is to improve the internal structure of the code without changing its observable external behavior.

How does it handle large-scale structural changes?

It breaks down large refactors into small, incremental, and verifiable steps, running tests after every change to prevent regressions.

What happens if my code doesn't have existing tests?

The skill will guide you to write characterization tests first to capture current behavior as a safety net before any refactoring begins.

개발자 도구

Refactors source code safely by identifying code smells and applying structural improvements while maintaining behavioral consistency through automated testing.

This skill provides a rigorous framework for refactoring code without altering its external behavior. It guides Claude through identifying common code smells—such as long functions, excessive parameters, and deep nesting—and applies transformations like function extraction and expression simplification. By enforcing a 'hard-gate' policy where tests must pass before and after every incremental change, it ensures that code improvements remain safe, maintainable, and free of regression bugs, effectively separating structural cleanup from feature development.
