Account Routing

  • Reads (list, get, free-time): Omit 
    account
    to query all accounts simultaneously.
  • Writes (create, update, delete, rsvp): You must specify 
    account
    . Ask the user if unclear.
google_calendar(command: "list")                                     // all accounts
google_calendar(command: "free-time --duration 60")                 // all accounts
google_calendar(command: "create --title 'Team Sync'", account: "Work")

Workflow: Scheduling a Meeting

  1. Find free time: 
    google_calendar(command: "free-time --duration 60 --days 5")
  2. Confirm a slot with the user.
  3. Create the event: 
    google_calendar(command: "create --title 'Meeting' --start '2026-04-15T14:00:00' --end '2026-04-15T15:00:00' --attendees 'alice@example.com'", account: "Work")

Free-Time Algorithm

free-time
fetches events from all connected accounts, merges overlapping busy intervals, and returns up to 10 available slots of at least the requested duration within the search window.

Error Handling

  • If no accounts are connected, direct user to Settings → Integrations.
  • If 
    account
    is required but not specified, ask the user which account to use before proceeding.
