Conciseness

The body is lean with no explanations of concepts Claude already knows, but the boundary instruction ("use ONLY when no API-specific skill applies") is repeated three times — in the intro, and again in the blockquote with the sibling skill list. This matches 'efficient; minor instances of over-explanation that could be trimmed' rather than the every-token-earns-its-place score 5.

Actionability

The command `scripts/search_docs.mjs "<topic or feature name>" --model ... --client-name ... --client-version ...` is concrete and executable, and the guidance "Search for the topic or feature name, not the full user prompt" is specific. It falls short of score 5 because the placeholder values (YOUR_MODEL_NAME, client name/version) are not copy-paste ready and no worked example query is given.

Workflow Clarity

This is a simple single-action skill under 50 lines: search the vector store before answering. The single action is unambiguous, framed as mandatory, and there are no destructive or batch operations that would require validation checkpoints. Under the simple-skill guidance this earns the top score; it is not score 4 because nothing is missing for a one-step flow.

Progressive Disclosure

The skill is under 50 lines with no need for external reference files; the single referenced path (scripts/search_docs.mjs) exists in the bundle, and the body is organized into clear sections (intro, mandatory search, boundary note, privacy notice). Per the rubric's guidance for short self-contained skills, this matches the top anchor.

Specificity

The description names the domain ("Shopify developer documentation across all APIs") and one concrete action ("Search"), but lists no additional capabilities. This matches the anchor for naming a domain with 1-2 concrete actions without comprehensive coverage — not score 2 because the action and domain are concrete rather than generic, not score 4 because only a single action is given.

Completeness

It answers both: what ("Search Shopify developer documentation across all APIs") and when ("Use only when no API-specific skill applies") — an explicit trigger clause, so it is not capped at 3. However the 'when' is exclusion-based and could be more explicit with concrete trigger phrases (e.g., when a question spans multiple APIs), fitting the 'both present but when could be more specific' anchor rather than score 5.

Trigger Term Quality

"Shopify developer documentation" and "APIs" are natural terms, but common variations users would actually say ("docs", specific API names like Admin API or Liquid, "shopify.dev") are missing. Some relevant keywords exist, but coverage lacks synonyms and variations, matching the middle anchor rather than the good-coverage anchor.

Distinctiveness Conflict Risk

The clause "Use only when no API-specific skill applies" is explicit de-confliction within a clear Shopify niche, making it mostly distinct from unrelated skills. But overlap risk remains with the closely related API-specific Shopify skills, since the guard depends on the reader knowing those siblings exist — matching 'mostly distinct; minor overlap risk' rather than the clear-niche score 5.
