Scored across 14 tools
Each tool targets a clearly distinct resource and action: account, contacts, campaigns, threads, messages, and numbers. The only potential overlap is get_thread returning messages alongside get_message_status, but the latter is a focused single-message lookup. Boundaries are unambiguous.
Almost all names follow a snake_case verb_noun pattern (e.g., get_account, create_campaign, send_message). Minor deviations: add_contacts uses a plural noun despite adding one contact per call, and mark_thread_read adds a third word. Still, the convention is clear and predictable.
14 tools is well within the typical 3–15 range and each tool has a distinct, necessary role in the SMS platform. There is no redundancy or bloat; the set feels appropriately scoped.
Core workflows are covered (send message, bulk campaign lifecycle, thread reading, number provisioning), but there are notable gaps: contacts support add and list but no update or delete, lists are referenced but have no management tools, and messages have no list operation. Agents can partially work around these gaps via threads.
