Implements proven refactoring patterns to systematically improve code structure and readability while preserving observable behavior.
The Refactoring Catalog skill provides a structured framework for identifying and applying low-risk code transformations based on industry standards from Martin Fowler and Michael Feathers. It guides developers through the process of eliminating code smells—such as duplication, long methods, and complex conditionals—by breaking down improvements into tiny, verifiable steps. By emphasizing a safety-first approach with test-driven validation, this skill helps reduce technical debt and cognitive load without risking functional regressions.
