TDQS
Scored across 28 tools
Each tool targets a distinct resource or action (e.g., create vs. search vs. list vs. get details). Even similar tools like get_company, get_company_list_entries, and get_company_lists have clearly different purposes. Detailed descriptions further eliminate ambiguity.
All tools follow a consistent pattern: 'affinity_' + verb + noun (e.g., create_company, list_persons, get_swimlanes). Verbs are appropriate and nouns match the entity. No mixing of styles or vague names.
28 tools is slightly high, but each covers a distinct aspect of the CRM (companies, persons, opportunities, lists, fields, notes, etc.). The scope justifies the count, though some tools could have been combined.
The tool set heavily favors read operations (get, list, search) and creation (add_note, create_company, create_person). Missing update and delete for most entities, and note modifications are explicitly unsupported. Agents cannot manage full lifecycles.
