Booking correctness beats clever conversation.
The assistant never says “you’re booked” until your field-service software confirms it. Availability comes from your calendar, windows are held while the customer decides, and two callers can never take the same slot.
Availability
Arrival windows from your technicians’ schedules minus existing appointments.
Rules
Minimum lead time, days ahead, windows offered, same-day cutoff with emergency exceptions.
Skills
No-cool goes to AC technicians; replacement consults to comfort advisors.
Capacity
Jobs per technician per day, with extra same-day capacity in Heat Mode.
Holds and races
A short hold protects the chosen window; the FSM's own uniqueness rejects double bookings.
Failure honesty
If the slot disappears or the FSM is unreachable, the customer hears the truth and gets alternatives or a priority callback.
Claude decides; the application executes.
The model interprets language, classifies intent, extracts details and phrases replies. The application owns permissions, state, pricing authorization, booking, service-area policy, safety, tenant boundaries and every tool call. There is no path from a caller’s words to your database.
