TDQS
Scored across 7 tools
Each tool targets a distinct calendar action or query: CRUD operations, conflict detection, free-slot search, and analytics. Even the two availability-related tools are clearly separated by purpose (finding free windows vs detecting overlaps).
All tool names follow a consistent snake_case verb_noun pattern (create_event, list_events, find_free_slots, etc.). The only compound name, delete_or_cancel_event, still uses the same style and a clear verb.
Seven tools is a well-scoped set for a Google Calendar server: it covers core event management plus useful scheduling helpers without bloat.
Core event lifecycle is covered (create, list, reschedule, delete/cancel) with useful extras like conflicts, free slots, and analytics. A generic event detail update beyond rescheduling would be a minor enhancement, but no critical workflow dead-ends are apparent.
