TDQS
Scored across 24 tools
Each tool targets a distinct resource and action: schedules, bookings, event types, calendars/availability, out-of-office, and user profile. Even closely related pairs like get-available-slots vs get-busy-times are separated by clear resource context.
All tools consistently use lowercase hyphenated verb-noun names (create-schedule, list-bookings, get-event-type). Collections use 'list', single resources use 'get', and actions use domain verbs like cancel/rescheduled/confirm, forming a predictable pattern.
At 24 tools, the set falls into the heavy 16-25 range and could feel large for an agent to navigate. However, the count is justified by the broad Cal.com domain covering five main resource areas; it is borderline rather than excessive.
Schedules, event types, and bookings have strong full lifecycle coverage, including create, read, list, update/delete, and booking-specific actions. Minor gaps exist—notably no update tool for out-of-office entries and no direct booking update—but these can be worked around without dead ends.
