Raw names from tools/list. Only developers need these.
| Arcade_ListApps | See the apps the current caller can act on and whether they are connected. Returns each app's id, name, connected state, and (when connected) the account it is connected as. Call this to answer "what apps do I have?" or when the caller's connection state may have changed since the session started. |
| GoogleCalendar_CreateEvent | Create a new event/meeting/sync/meetup in the specified calendar. Pass `recurrence` to create a repeating event. |
| GoogleCalendar_DeleteEvent | Delete an event from Google Calendar. |
| GoogleCalendar_FindTimeSlotsWhenEveryoneIsFree | Provides time slots when everyone is free within a given date range and time boundaries. |
| GoogleCalendar_ListCalendars | List all calendars accessible by the user. |
| GoogleCalendar_ListEvents | List events from the specified calendar within the given datetime range. min_end_datetime serves as the lower bound (exclusive) for an event's end time. max_start_datetime serves as the upper bound (exclusive) for an event's start time. For example: If min_end_datetime is set to 2024-09-15T09:00:00 and max_start_datetime is set to 2024-09-16T17:00:00, the function will return events that: 1. End after 09:00 on September 15, 2024 (exclusive) 2. Start before 17:00 on September 16, 2024 (exclusive) This means an event starting at 08:00 on September 15 and ending at 10:00 on September 15 would be included, but an event starting at 17:00 on September 16 would not be included. |
