Notes

• Confirmation: Always confirm the event summary, date/time, and attendees before creating, updating, or deleting an event.
• Calendar IDs: primary refers to the user's main calendar; other calendars can be referenced by name or email.
• Timezone Awareness: The CLI supports timezone-aware timestamps; prefer ISO timestamps (e.g., 2025-01-15T14:00:00Z).
• JSON Output: Use the --json flag when structured event details are required for parsing.
