Scored across 14 tools
Each tool targets a distinct action+resource pair: the only near-pairs are lookup_postcode (postcode→address) vs search_address (address→postcode), and search_company (name search) vs search_listed_companies (EDINET industry/capital filter), and the descriptions make the direction and intent clear. The set spans several unrelated domains (concierge requests, takeout, corporate registry, shipping quotes), which is broad but each tool's boundary is legible.
All 14 tools follow a strict snake_case verb_noun pattern (check_*, get_*, list_*, search_*, place_*, quote_*, request_*, lookup_*), with verbs chosen consistently for read-only lookups versus mutating/creating actions.
14 tools sits comfortably inside the healthy 3-15 range, and each maps to a real capability (service requests, takeout ordering, company/tax lookup, postcode lookup, shipping quote). The only mild concern is that the surface bundles four loosely related sub-domains, but no individual tool feels padded.
Core read and create paths are covered (search→profile, menu→order, request→status), but lifecycle gaps exist: there is no cancel_request or refund tool despite descriptions promising cancellation/refunds, and takeout orders have no status or cancellation follow-up unlike service requests.
