  - `calendars` (string, optional): Comma-separated calendar IDs (default: primary)

## Usage Guidelines

- Time format: RFC3339 — `2024-01-15T09:00:00Z` (UTC) or `2024-01-15T09:00:00+09:00` (with timezone).
- All-day events: use date format `YYYY-MM-DD` with `all_day=true`.
- Default calendar is `"primary"`.

## Common Operations

**Schedule a meeting**: Use `create_event` with `attendees` parameter for full control over time, description, and reminders.

**Find available time**: Call `check_availability` with the relevant calendar IDs and time range before creating events to avoid conflicts.

**Quick scheduling**: `quick_add_event` accepts natural language (e.g., "Lunch with Sarah tomorrow at noon"). Convenient but less precise than `create_event`.

**Reschedule**: Use `update_event` with new `start_time` and `end_time`. Only the fields you provide will be changed.
