Conciseness

Every section is purely operational with no concept explanation Claude already knows, sitting just below the lean anchor. The one trim instance is the "Execution" bash example, which repeats a third full JSON payload nearly identical to the "Common QuickGO patterns" already shown under Input.

Actionability

Copy-paste-ready JSON payloads with concrete values ("limit":10, "max_items":10, Accept header), specific endpoint paths, an executable bash one-liner, and explicit success/failure output contracts fully match the anchor for executable, common-case-covering guidance.

Workflow Clarity

This is a single-action skill with an unambiguous invocation, and it still includes error-recovery guidance ("fall back to ontology term lookup or UniProt GO annotations" when the annotation Solr backend is unavailable) and re-run discipline. Per the simple-skill exception, the unambiguous single action with explicit fallback earns the top anchor; the destructive/batch validation cap does not apply.

Progressive Disclosure

The body is under 50 lines with clear section headers, its only bundle file (scripts/rest_request.py) exists and implements the documented interface, and the References section explicitly bounds the bundle to SKILL.md plus that script. This fits the simple-skill exception for well-organized content with no needed external references.

Specificity

"Submit compact QuickGO requests for GO terms, annotations, and ontology traversal" names the domain and three action areas, matching the several-specific-actions anchor. It falls short of 5 because the phrasing is mechanism-level ("submit requests") rather than naming distinct capabilities like looking up term details, fetching gene product annotations, or finding children/ancestors.

Completeness

Both parts are explicit: the "what" ("Submit compact QuickGO requests for GO terms, annotations, and ontology traversal") and the "when" ("Use when a user wants concise QuickGO summaries"). It is not 5 because the "when" clause is narrow and somewhat circular, triggering on QuickGO by name rather than concrete phrases like GO terms, gene ontology, or gene annotations.

Trigger Term Quality

Natural terms present include "QuickGO", "GO terms", "annotations", and "summaries", giving good keyword coverage. It is not 5 because common synonyms and variations users would say are missing ("gene ontology", "gene product", "protein annotations").

Distinctiveness Conflict Risk

QuickGO is a clearly defined niche API, and the triggers (GO terms, annotations, ontology traversal) are domain-specific with minimal overlap risk against generic skills. It clearly matches the clear-niche anchor.
