Every section earns its place—tables compress mechanics efficiently, the rhythm diagram is minimal yet clear, and there's no explanation of what refactoring is beyond the one-line definition. Assumes Claude knows programming concepts.

Provides fully executable Python code in the worked example, specific mechanics for each refactoring type in table form, and a concrete step-by-step process. The output format template is copy-paste ready.

The rhythm section explicitly shows the test→step→test→commit loop with a clear revert path on red. The worked example demonstrates validation at each step (Steps 3 and 5), and every commit is described as a safe revert point.

Content is well-organized with clear sections and tables, but references to external skills (code-smell-detector, behavior-preservation-checker) are mentioned inline without clear navigation structure. The skill is appropriately self-contained but could better signal these as optional deep-dives.

Lists multiple specific concrete actions: 'extract method, inline, rename, move' and describes the methodology 'small, behavior-preserving steps with a test between each'.

Clearly answers both what ('Executes refactorings — extract method, inline, rename, move — in small, behavior-preserving steps with a test between each') and when ('Use when the user wants to restructure working code, when cleaning up after a feature lands, or when a smell has been identified').

Includes natural terms users would say: 'refactorings', 'extract method', 'inline', 'rename', 'move', 'restructure', 'cleaning up', 'smell'. These are standard developer vocabulary for refactoring tasks.

Clear niche focused specifically on refactoring operations with distinct triggers like 'extract method', 'inline', 'rename', 'move', 'smell', and 'behavior-preserving'. Unlikely to conflict with general coding or testing skills.
