Conciseness

The body is lean: no concept-teaching padding, no installation or library explanations, and every section carries operational content. It falls short of 5 because the 'Usage Rules' section repeats the per-tier guidance from the 'Shadow Utilities' subsections nearly verbatim three times ('Use `Beautiful sm` for compact cards, form controls, pills...' duplicates 'Use for compact cards, form controls, pills, and quieter surfaces'), which could be trimmed to a single rule.

Actionability

Each tier provides the exact, copy-paste-ready Tailwind arbitrary-value shadow class in a code block, and the Examples section shows a complete HTML usage. The guidance is fully executable and covers the common cases (three elevation strengths), matching the anchor for 5.

Workflow Clarity

This is a simple, single-purpose skill (pick the tier matching the surface, apply the class), and the selection action is unambiguous: each tier's target surfaces are listed, plus explicit rules ('Use one shadow strength per component state') and an Avoid section covering misuse. No destructive or batch operations exist, so no validation checkpoints are required.

Progressive Disclosure

The skill is short (~53 lines of body) with no bundle files and no need for external references; per the simple-skill exception, well-organized sections (Use When, Shadow Utilities, Examples, Usage Rules, Avoid) earn a 5. All content is appropriately inline for a skill of this size.

Specificity

"Apply exact Tailwind arbitrary shadow utilities for polished, layered neutral elevation" names the domain and a single concrete action, but does not enumerate several specific capabilities (e.g., the three elevation tiers sm/md/lg), matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. Score 4 would require several listed actions, which are absent.

Completeness

It explicitly answers what ("Apply exact Tailwind arbitrary shadow utilities for polished, layered neutral elevation") and when ("Use when compact cards, controls, panels, popovers, hero media, feature callouts, or modal-like containers need refined shadows") with concrete trigger phrases, matching the anchor for 5 exactly.

Trigger Term Quality

"compact cards, controls, panels, popovers, hero media, feature callouts, or modal-like containers" plus "refined shadows", "default Tailwind shadow scales", "colored tinting" give good natural keyword coverage. It falls short of 5 because common synonyms users would actually say — "box shadow", "elevation", "drop shadow", "depth" — appear only obliquely ("elevation" does appear once as "neutral elevation"), not as direct trigger phrases.

Distinctiveness Conflict Risk

The niche is clear — exact Tailwind arbitrary-value shadow classes, explicitly differentiated from "default Tailwind shadow scales or colored tinting" — with distinct triggers. It is mostly distinct with minor overlap risk with general design/styling or dataviz shadow guidance, so 4 rather than 5.
