About
This skill provides a structured framework for improving existing codebases without altering their external behavior. It guides Claude through a safety-first approach that prioritizes characterization testing, incremental changes, and the identification of common code smells like long methods or duplicate logic. By utilizing proven techniques such as method extraction and conditional-to-polymorphism transformations, it helps developers transform legacy or complex code into clean, modular, and readable production-grade software while ensuring functionality remains identical.
