Scored across 25 tools
With 25 tools there is real density, but each search tool targets a distinct vertical/source (web, news, academic, clinical, legal, patent, econ, local, image, awesome lists, monarch) and descriptions explicitly cross-reference each other to redirect the agent. The near-neighbors (verify_citation vs audit_bibliography vs verify_recommendation; scrape_page vs search_and_scrape vs paper_fulltext) are clearly scoped and differentiated in their descriptions. Only minor edge ambiguity remains among the many *_search tools.
Names are uniformly snake_case with a dominant, predictable X_search convention, plus consistent verb_noun forms (scrape_page, verify_citation, format_bibliography, archive_source). A few are noun phrases (citation_graph, paper_fulltext, research_export) rather than verb_noun, a minor deviation. No mixed casing or chaotic verb styles.
At exactly 25 tools this sits at the heavy end of the rubric. Each tool maps to a genuinely distinct data source or lifecycle step, so few feel redundant, but the surface is large enough that agents must navigate many similar-sounding options. Borderline rather than clearly over-scoped.
The surface covers the full research lifecycle: discovery (web/news/academic/vertical searches), reading (scrape_page, search_and_scrape, paper_fulltext), verification (verify_citation, audit_bibliography, verify_recommendation), citation (format_bibliography), archiving (archive_source), session tracking (sequential_search, get_research_session), and export (research_export). No obvious dead ends remain for a research server's purpose.
