Lists multiple concrete actions: 'conducts systematic visual audits', 'produces phased, implementation-ready design plans', and specifies scope areas like 'spacing/typography/color', 'visual hierarchy', 'design consistency'. Also clearly scopes what it does NOT do (functionality, logic, features).

Clearly answers both 'what' (conducts visual audits, produces phased design plans, refines spacing/typography/color/hierarchy) and 'when' with an explicit 'Use this skill whenever...' clause plus additional trigger phrases. Also includes a boundary statement clarifying it's purely visual.

Excellent coverage of natural trigger terms users would actually say: 'audit a UI', 'make it look better', 'UI polish', 'visual refinement', 'design pass', 'design review', 'make an app feel more professional', 'polished or premium'. These are highly natural phrases.

Clearly carved out niche: visual-only UI/UX auditing and refinement of existing apps. The explicit boundary ('purely visual — does not touch functionality, logic, or features') and specific trigger terms like 'design audit', 'visual refinement' make it highly distinguishable from general coding or feature-building skills.

The skill is mostly efficient and well-structured, but includes some philosophical framing ('feel inevitable', 'like no other design was ever possible') that doesn't add actionable value. The audit dimensions table is dense but each row earns its place. Some reduction filter questions are somewhat redundant with each other.

The skill provides a clear structured process and specific dimensions to evaluate, but lacks concrete executable examples — no code snippets for implementation, no example audit output, no sample design token proposals. The guidance is specific in what to evaluate but abstract in how to produce the deliverable, relying on an external template file for the actual output format.

The four-step workflow is clearly sequenced with explicit checkpoints: audit → reduce → compile plan → wait for approval. The approval gate before implementation is a strong validation checkpoint. Post-implementation steps include verification (before/after comparison) and documentation updates. The phase-by-phase execution with review between phases provides a clear feedback loop.

Content is well-organized with clear sections. References to external files (design-principles.md, audit-template.md) are one level deep and clearly signaled. The prerequisite reading list is upfront, and the main content stays focused on the audit process rather than inlining reference material.
