  • check_calendars

    Check that the user's calendars can be read. Returns each calendar's name, how many events it holds and how many block time in the next 14 days. Use it when free_slots fails or to confirm the setup. Returns no event details and no calendar addresses.

  • free_slots

    Find when the user is free. Reads the user's own calendars and returns, for each day asked about, the time ranges with no events, in the user's time zone.

  • status

    Whether the user is free right now, until when, and their next free slot. Use it for "am I free now?", "when is my next gap?" or before interrupting the user. Returns no event titles.
