Scheduling is where an agent either saves real time or quietly makes a mess, so the interesting part here is the availability query: it checks several calendars at once and reports the windows where everyone is free before anything gets booked. Beyond that it lists and searches events, creates and updates them with attendees and recurrence, and handles multiple calendars and time zones. Access is OAuth against the user's own Google account.
