Scored across 8 tools
Each tool has a clearly distinct purpose: search, search with context, crawl, extract, map, research creation, research retrieval, and usage monitoring. No overlap or ambiguity.
All tools follow the consistent 'tavily_<verb>' pattern, using clear action verbs like search, crawl, extract, map, research_create, research_get, and usage. No mixing of conventions.
8 tools is appropriate for a web search and research service, covering core operations without being excessive or insufficient.
The tool surface covers search, crawling, extraction, site mapping, research tasks, and usage monitoring. Minor gap: no tool to list or cancel research tasks, but core workflows are covered.
