Conciseness

Lean and efficient with no padding; it never explains what refactoring or tests are, and every bullet and step earns its place assuming Claude's competence.

Actionability

Concrete executable guidance throughout: exact commit message format ('- r <refactoring>'), 'Find or create ./test.sh, verify all tests pass', and the literal cue "say 'Entering final evaluation.'". The guidance is copy-paste ready for a process skill.

Workflow Clarity

Clear staged sequence (Prep, Main Refactoring, Final Evaluation, Summary) with explicit validation checkpoints (tests pass before and after each change) and a feedback loop in final evaluation (fix one thing, look again, repeat).

Progressive Disclosure

A self-contained process skill under ~72 lines with no need for external reference files; content is well-organized into clear sections, satisfying the simple-skill exception.

Specificity

Lists five concrete actions ('extracting methods, renaming symbols, simplifying conditionals, removing duplication, and eliminating dead code') plus the behavior-preservation test gating, giving comprehensive concrete coverage.

Completeness

Explicitly answers both 'what' (the refactoring actions plus test gating) and 'when' ('Invoke immediately when user mentions...') with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural trigger coverage with synonyms ('refactor', 'refactoring', 'clean up', 'restructure', 'simplify', 'technical debt', 'code smell', 'DRY violations', 'messy, complex, or hard to maintain') that users would actually say.

Distinctiveness Conflict Risk

Refactoring is a clear niche with distinct, specific triggers; the explicit invoke clause and enumerated phrases minimize overlap with unrelated skills.
