Quality

Content

56%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is rich and largely actionable with good examples and a clear design workflow, but it is substantially over-long, re-teaching fundamentals Claude already knows, and its two external references point to files that are missing from the bundle.

Suggestions

Trim or move background material Claude already knows (WCAG basics, easing definitions, Gestalt principles, semantic HTML) into the referenced sub-files so SKILL.md stays a lean overview.

Create the referenced DESIGN-SYSTEM-TEMPLATE.md and MOTION-SPEC.md (or remove the citations) so the signaled navigation paths actually resolve.

Add an explicit validate-fix-retry loop to the Design Workflow's Validate step so failures have a documented recovery path.

DimensionReasoningScore

Conciseness

At ~730 lines the body noticeably over-explains concepts Claude already knows (WCAG contrast ratios, line-height rules, easing curves, Gestalt principles, semantic HTML, 44px touch targets, what dark mode is), with padded aphorisms like 'The best technology disappears' and 'Every screen should feel balanced'.

2 / 5

Actionability

Provides concrete, copy-paste-ready guidance: Tailwind/tsx button and motion examples, a full rem type scale, timing tables, named tooling (shadcn, phosphor, sonner, clsx), and specific palette values, with only minor gaps in edge-case coverage.

4 / 5

Workflow Clarity

The Design Workflow lays out a clear sequence (Understand Context -> Explore Options -> Implement Iteratively -> Validate) reinforced by a Design Decision Checklist, though the Validate step lacks an explicit error-recovery feedback loop.

4 / 5

Progressive Disclosure

Section structure is present and references to DESIGN-SYSTEM-TEMPLATE.md and MOTION-SPEC.md are clearly signaled one level deep, but those referenced files do not exist in the bundle and large blocks of detail (motion specs, color theory) remain inlined rather than split out.

Description

83%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-structured description that clearly states both purpose and trigger conditions with concrete examples. It is mostly specific and distinct, with only minor gaps in trigger synonyms and some breadth in the 'build web...' clause.

DimensionReasoningScore

Specificity

Lists several concrete use areas ('visual decisions, colors, typography, layouts' and 'build web components, pages, or applications'), giving good coverage of the design domain, though framed as advisory 'guidance for' rather than crisp verbs like 'extract, fill, merge'.

4 / 5

Completeness

Explicitly answers both what ('Expert UI/UX design guidance for unique, accessible interfaces') and when ('Use for...', 'Use this skill when the user asks to build web components, pages, or applications') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural terms users would say ('colors', 'typography', 'layouts', 'build web components', 'pages', 'applications', 'UI/UX'), but misses common synonyms such as 'design', 'styling', 'CSS', or 'theme'.

4 / 5

Distinctiveness Conflict Risk

The UI/UX design framing carves a clear niche, but 'build web components, pages, or applications' is broad enough to overlap with general web-development skills.
