Conciseness

Every line is a functional check with concrete thresholds ('Body text 50-75 characters per line', '150-200ms ease', '44x44px on mobile', 'WCAG AA (4.5:1 for body)'), not explanation of concepts Claude already knows. The tables, severity guide, output template, and tips all earn their tokens; there is no padding or tutorial-style prose, so no neighbor anchor fits better.

Actionability

The check tables give measurable good/bad criteria, the severity guide is concrete, and the Output section provides a copy-paste-ready report template with an exact path ('.jez/artifacts/design-review.md'). It misses a 5 because 'Browser Tool Detection' and 'URL Resolution' defer entirely to another skill ('Same as ux-audit — Chrome MCP, Playwright MCP, or playwright-cli') without inlining the actual steps, leaving a gap if that skill's content is unavailable.

Workflow Clarity

The operational flow (resolve URL → detect browser tool → run the 7 check categories → assign severity → write the report) is only implicit in section ordering; there is no explicit step sequence or checkpoint (e.g., 'screenshot both light and dark mode before writing findings' exists only as a tip). This matches 'sequence present but checkpoints missing or implicit'; the destructive/batch cap does not apply since this is a read-only review, and a 4 would require an explicit sequence.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), and the single SKILL.md is well-organized into clear sections with a consistent table format. The 7 check-category tables (~150 lines total) could arguably live in a reference file to slim the main file, which is the minor organization gap separating this from a 5; the under-50-lines simple-skill exception does not apply.

Specificity

The description enumerates eight concrete review dimensions ('layout, typography, spacing, colour, hierarchy, consistency, interaction patterns, and responsive behaviour') plus a concrete deliverable ('Produces a design findings report with screenshots'), which is several specific capabilities with only minor gaps. It falls short of a 5 because it is effectively one action (review) with many objects rather than multiple distinct concrete actions like 'extract text, fill forms, merge documents'.

Completeness

It explicitly answers 'what' ('Review a web app or page for visual design quality — layout, typography... Produces a design findings report with screenshots') and 'when' ('Triggers: ...' with nine concrete phrases), plus a scope boundary ('Not a UX audit (that checks usability)'). This clearly matches the anchor-5 example structure of what + explicit trigger phrases.

Trigger Term Quality

Nine natural trigger phrases are quoted verbatim: 'design review', 'does this look good', 'review the design', 'check the layout', 'is this polished', 'visual review', 'design audit', 'make it look better', 'it looks off' — covering synonyms ('design review'/'visual review'/'design audit') and exact phrasings a user would naturally say. This comprehensively matches the anchor-5 example's coverage including common variations.

Distinctiveness Conflict Risk

It carves out a clear niche by explicitly distinguishing from the nearest sibling skill: 'Not a UX audit (that checks usability) — this checks whether it looks professional and polished'. Combined with distinctive triggers like 'is this polished' and 'it looks off', conflict risk with other skills is minimal.
