Detailed Usage

list -- List calendars

gws calendar list

Lists all calendars you have access to, including shared calendars and subscriptions.

events -- List events

gws calendar events [flags]

Lists upcoming events from a calendar.

Flags:

• --calendar-id string -- Calendar ID (default: "primary")

Tips for AI Agents

• Always use --format json (the default) for programmatic parsing
• Use gws calendar events to get event IDs, then use those IDs for update/delete/rsvp/get/move
• Time format accepts both RFC3339 (2024-02-01T14:00:00Z) and human-friendly (2024-02-01 14:00)
• The update command uses PATCH (not PUT), so only changed fields are sent
• For non-primary calendars, get the calendar ID from gws calendar list first
• Use quick-add for natural language event creation (e.g. "Meeting with Bob next Tuesday 2pm")
• Use freebusy to check availability before creating events
• ACL roles: freeBusyReader < reader < writer < owner
• Default event window is 7 days; increase with --days for broader views
