Conciseness

The body is lean and dense: a four-snippet JSON quick-reference, a parameter table with a "When to use" column, terse anti-patterns, and a short "After Crawling" section. It explains nothing Claude already knows, and every token earns its place, matching the anchor-5 example. It is not 4 because there is no over-explanation left to trim.

Actionability

Copy-paste-ready tool-call JSON covers the common cases (sitemap crawl, scoped BFS, URL-map discovery, authenticated crawl), and the parameter table gives types, defaults, and usage guidance (e.g., "include_patterns — ALWAYS add to stay in scope"). It is not 4 because the examples are complete and executable, not just mostly concrete.

Workflow Clarity

A sensible flow exists (pick strategy and limits via the quick-reference and anti-patterns → crawl → query with cache/find_similar), but a crawl is a batch operation and there is no validation or verification checkpoint — e.g., confirming the returned page count or that pages actually landed in the cache before issuing cache/find_similar queries. Per the rubric's batch-operation cap, workflow clarity cannot exceed 3 here. It is not 2 because "After Crawling" does sequence the follow-up steps explicitly.

Progressive Disclosure

Well-organized sections (Quick Reference, Parameters, After Crawling, Anti-Patterns, When NOT to use, See Also) with one-level-deep references to sibling skills. It is not 5 because the body is ~64 lines (above the under-50 simple-skill threshold) and the full 12-row parameter table is bulk reference material that could live in a separate reference file; it is not 3 because structure and navigation are clear with nothing buried.

Specificity

"multi-page crawl with sitemap, BFS, DFS, and URL-map strategies, anchor-fragment dedup, rate limiting, robots.txt respect, and automatic local cache population" lists multiple specific concrete actions with comprehensive coverage of strategies and side-effects, matching the anchor-5 example's breadth. It is not 4 because there are no coverage gaps — the crawl strategies, dedup behavior, safety limits, and cache side-effect are all explicitly named.

Completeness

It explicitly answers what ("Local-first multi-page crawl with ... strategies ... and automatic local cache population") and when ("Use when the user wants to index documentation, crawl a docs site, extract all pages under a path, or says 'crawl', 'index this site'...") with concrete trigger phrases, matching the anchor-5 example. It is not 4 because the 'when' is fully explicit with quoted user utterances rather than merely adequate.

Trigger Term Quality

Good keyword coverage with natural quoted phrases users would say: "crawl", "index this site", "get all the docs", "bulk extract", plus "index documentation" and "crawl a docs site". It is not 5 because common synonyms such as "scrape", "spider", or "harvest" are missing; it is not 3 because the quoted trigger list goes well beyond a couple of generic keywords.

Distinctiveness Conflict Risk

A clear niche (multi-page crawl that populates the local cache) is carved out against the single-page fetch case via "Prefer when crawled pages should land in a reusable local cache for later cache / find_similar queries", giving minimal conflict risk with sibling skills. It is not 4 because the description both defines the niche and explicitly steers the main boundary case.
