## Detailed Usage

### list -- List calendars

```bash
gws calendar list
```

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

### events -- List events

```bash
gws calendar events [flags]
```

Lists upcoming events from a calendar.

**Flags:**
- `--calendar-id string` -- Calendar ID (default: "primary")
- `--days int` -- Number of days to look ahead (default 7)
- `--from string` -- Start date (YYYY-MM-DD or RFC3339); defaults to now. Enables fetching past events.
- `--max int` -- Maximum number of events (default 50)
- `--pending` -- Only show events with pending RSVP (needsAction). Tip: increase `--max` when using `--pending` over long date ranges, since `--max` limits the API fetch before client-side filtering.
- `--query string` -- Free-text search across summary, description, location, and attendees
- `--event-types strings` -- Filter by event type: `default`, `birthday`, `focusTime`, `fromGmail`, `outOfOffice`, `workingLocation`
- `--show-deleted` -- Include cancelled/deleted events in results
- `--timezone string` -- Timezone for response times (e.g. `America/New_York`)
- `--updated-min string` -- Only events modified after this time (RFC3339)

**Output includes** (fields omitted when empty):

## 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
