Conciseness

The body is lean throughout — a compact Quick Reference, a parameter table, a five-step process list, and a short steps example — with zero explanation of concepts Claude already knows; every section is load-bearing, matching the 5 anchor rather than the 4 anchor's 'minor instances of over-explanation'.

Actionability

Copy-paste-ready JSON payloads and a complete parameter table (types, defaults, hard caps, citation_format options) give mostly executable guidance, but there is no end-to-end invocation/response example showing how results are returned — short of the 5 anchor's 'specific examples cover the common cases', while clearly above the 3 anchor's pseudocode level.

Workflow Clarity

The 'How It Works' section gives a clear five-step sequence (Plans, Executes, Extracts, Synthesizes, Reports) plus a verification mechanism ('Use steps to debug weak results — if extraction is poor, check which pages were fetched') for the batch fetch operation, matching the 4 anchor; it is not 5 because there is no explicit validate-fix-retry checkpoint loop.

Progressive Disclosure

No bundle files exist, so this rests on the body alone: a well-sectioned single-purpose usage doc (~76 lines) with clearly signaled one-level-deep 'See Also' links to sibling skills. It sits at the 4 anchor because the full parameter/citation-format detail could arguably live in a reference file and the body exceeds the under-50-line threshold that would let well-organized sections alone score 5.

Specificity

The description lists four distinct concrete actions covering the full pipeline — 'plans search queries and URLs', 'executes in parallel within a time budget', 'extracts structured fields via JSON Schema', 'synthesizes results' — with no coverage gaps, matching the comprehensive multiple-concrete-actions anchor rather than the 4 anchor's 'minor gaps'.

Completeness

It explicitly answers both what (the plan/execute/extract/synthesize pipeline) and when ('Use when the user needs data collected from the web with a specific shape, says "gather data"…') with concrete trigger phrases, matching the 5 anchor exactly; the when-clause is already fully explicit, so the 4 anchor's 'could be more explicit' doesn't apply.

Trigger Term Quality

Natural trigger phrases like 'gather data', 'find pricing for', 'collect information about', and 'extract from multiple sites' are explicitly quoted, giving good keyword coverage, but common synonyms such as 'scrape', 'web search', or 'look up' are missing — below the 5 anchor's comprehensive synonym coverage, above the 3 anchor's missing-variations level.

Distinctiveness Conflict Risk

The niche — autonomous multi-source gathering with schema-shaped output — is clear and mostly distinct, but the trigger 'extract from multiple sites' overlaps the sibling wigolo-extract skill and the description itself draws no boundary against it (only the body does), placing it at the 4 anchor's 'minor overlap risk with closely related skills' rather than the 5 anchor.
