TDQS
Scored across 20 tools
Most tools have distinct purposes, but `get_call` and `get_call_transcript` overlap significantly—both retrieve call transcripts, creating ambiguity about which to use. `get_country_rates` vs `lookup_rate` are sufficiently differentiated by scope (country-wide vs specific number).
Excellent consistency with strict snake_case and verb_noun pattern throughout (e.g., `buy_phone_number`, `list_calls`, `inject_context`). All 20 tools follow the same grammatical structure without mixing conventions.
Twenty tools is well-scoped for a telephony platform with AI agents, covering number lifecycle (search/buy/manage), call operations (make/transfer/hangup), account management, and AI controls without bloat.
Strong coverage with minor gaps. Missing `delete_phone_number` or `release_phone_number` leaves the number lifecycle incomplete (no way to stop renting). Active call controls cover essential operations (hangup, transfer, inject) but lack hold/resume functionality.
