Conciseness

The body is dense, token-efficient reference material — anti-pattern tables, exact hex/class tokens, and code snippets — that assumes Claude's competence without explaining what WCAG or Tailwind is. A few explanatory phrases ('To deliver a premium visual and interactive experience:') and some redundancy between the anti-pattern table and the final checklist could be trimmed, keeping it just below a 5.

Actionability

Guidance is fully executable: copy-paste-ready TSX snippets (typography scale, Pressable with accessibility attributes), exact Tailwind class tokens and hex values in the color matrix, a concrete runnable command ('node scripts/audit-ui-contrast.js') that exists in the bundle, and a specific PR verification checklist. The common cases (contrast, dark mode pairs, touch targets, states) are all covered concretely.

Workflow Clarity

The audit workflow and the PR checklist provide a clear sequence with explicit verification checkpoints, and the anti-pattern table's 'Correct Alternative' column covers remediation. Not 5 because there is no explicit fix-and-rerun feedback loop after the audit script reports violations — re-running until 0 HIGH severity violations is only implied by the checklist.

Progressive Disclosure

The body is well organized into 9 clear sections, and its single bundle reference (scripts/audit-ui-contrast.js) is real, correctly pathed, and clearly signaled with usage context. Not 5 because the document is ~190 lines of inline reference detail (e.g., the full approved color token matrix and status pill specs) that could arguably be split into a references/ file to keep SKILL.md as a leaner overview.

Specificity

The description lists several specific capability areas — 'accessibility checks (contrast/white-on-white detection)', 'layout grid', 'typography hierarchy', 'touch targets', 'state management' — with minor gaps in coverage. It falls short of 5 because it uses noun-phrase topics rather than concrete action verbs, and 'state management' is ambiguous (app state vs. UI states).

Completeness

It has a clear 'what' (design standards, accessibility checks, audit guidelines) but no 'Use when...' clause or equivalent explicit trigger guidance; the trailing 'for POSCursor/POS Cursor' only weakly implies when to use it. Per the judging guidelines, a missing 'Use when' clause caps completeness at 3.

Trigger Term Quality

Good keyword coverage with natural terms users would say ('UI/UX design standards', 'accessibility', 'contrast', 'typography', 'touch targets'). Not 5 because common variations and synonyms are missing, such as 'design review', 'dark mode', 'WCAG', or 'design audit'.

Distinctiveness Conflict Risk

The 'for POSCursor/POS Cursor' scoping establishes a clear niche, minimizing conflict risk with other skills. Not 5 because the leading generic terms ('UI/UX design standards', 'accessibility checks') create minor overlap risk with general UI/design skills.
