Conciseness

The body is lean with copy-paste curl commands and no padding of concepts Claude already knows; the only redundancy is the Overview repeating the frontmatter description verbatim, keeping it just below the 5-anchor.

Actionability

Each endpoint ships a concrete, executable curl example with the auth header, but no example responses or payload schemas are shown inline (deferred to the OpenAPI spec), leaving minor gaps versus the 5-anchor.

Workflow Clarity

Endpoints are listed clearly, but 'DELETE /api/cache — Clear all caches' is a destructive batch operation with no validation or verification checkpoint, and the rubric explicitly caps such skills at 3 even when single-purpose.

Progressive Disclosure

Content is well-organized into Overview, Authentication, Endpoints, and Payloads sections with a clearly signaled one-level reference to the OpenAPI spec for detailed schemas; minor gaps (the redundant Overview, an external rather than bundled spec reference) keep it at 4.

Specificity

Lists four concrete actions — 'View cache statistics, clear entries, configure TTL policies, and control semantic-similarity caching thresholds' — giving comprehensive coverage of the cache-management domain, matching the 5-anchor's 'multiple specific concrete actions'.

Completeness

Clearly states what the skill does but has no 'Use when...' clause or equivalent trigger guidance; per the rubric guideline, a missing explicit trigger caps completeness at 3.

Trigger Term Quality

Includes natural terms a user would say ('cache', 'clear entries', 'cache statistics', 'TTL') but leans technical and omits common variations/synonyms like 'flush cache' or 'cache hit rate', fitting the 4-anchor's 'good keyword coverage; a few natural terms missing'.

Distinctiveness Conflict Risk

Targets a clear niche (LLM response cache management) with minimal conflict risk against unrelated skills, though the absence of an explicit trigger phrase leaves minor overlap risk with neighboring admin/ops skills.
