Conciseness

The body is efficient — a compact Quick Reference, a tight parameters table, and short sections with no concept explanations Claude already knows. It falls at the 4-anchor ('efficient; minor instances of over-explanation that could be trimmed') because the "instant (0ms network), free (no engine query)... a redundant fetch wastes 5-15 seconds" justification in The Cache-First Workflow section restates the intro's motivation and could be cut to just the rule and example.

Actionability

Six copy-paste-ready JSON invocations in Quick Reference cover the common cases (keyword search, URL scoping, hybrid mode, date filter, stats, change detection, clear), the parameters table gives types/defaults, and the workflow shows two concrete executable calls. This matches the 5-anchor ('fully executable; copy-paste ready... specific examples cover the common cases') and is not a 4, which implies minor gaps in executable coverage.

Workflow Clarity

The cache-first sequence is present (probe → fall through to search), but the skill's destructive operation (`clear: true` deletes entries) has no validation/verification step — no guidance to first run the query/url_pattern to review what matches before deleting. Per the judging guidelines, missing validation in workflows involving destructive or batch operations caps workflow clarity at 3 ('sequence present but checkpoints missing or implicit'); the handler's refusal of unscoped wipes is a guardrail, not a validate-first feedback loop, so it does not lift the cap.

Progressive Disclosure

The body is a clear, well-organized overview of a single tool — Quick Reference, Parameters, workflow, modes, stats, anti-patterns, and a See Also section of one-level-deep, clearly labeled references to sibling skills. Nothing that belongs in a separate file is inlined, and navigation is trivial, matching the 5-anchor ('clear overview with well-signaled one-level-deep references; content appropriately split').

Specificity

The description lists multiple concrete actions — "full-text and hybrid semantic search", "clears matching entries", "re-checks cached URLs for changes" — comprehensively covering the skill's capabilities. This matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and exceeds the 4-anchor, whose example lists a comparable number of actions with minor gaps; the only uncovered capability (stats) is still surfaced via the trigger "cache stats".

Completeness

Both 'what' ("Local-first knowledge cache — full-text and hybrid semantic search over every page wigolo has already fetched, crawled, or searched") and 'when' ("Use before any web request" plus "Triggers when the user says...") are explicitly and concretely answered, matching the 5-anchor exactly. It is not a 4 because the 'when' clause is fully explicit with concrete trigger phrases rather than merely serviceable.

Trigger Term Quality

Natural phrases users would actually say are comprehensively covered with variations: "check the cache", "have we seen this", "what's on disk", "search what I've already fetched", "cache stats", "what changed since I last looked". This matches the 5-anchor's 'comprehensive coverage of natural terms including synonyms' and clearly exceeds the 4-anchor ('a few natural terms missing').

Distinctiveness Conflict Risk

The niche is clear — probing a local cache before web requests, with cache-specific triggers — but phrases like "what's on disk" and "have we seen this" carry minor overlap risk with filesystem/memory-style skills, fitting 'mostly distinct; minor overlap risk with closely related skills'. It is not a 5 because a couple of triggers are generic enough to fire in adjacent contexts; it is well above a 3, whose examples are broadly generic domain claims.
