description	Read Google Calendar events and check availability using gws CLI. Use this skill when any Founder OS plugin needs to list events, check schedules, or query free/busy status — replaces Google Calendar MCP server read operations.

Overview

Calendar read operations via gws CLI. Covers listing events, getting event details, and checking availability.

Prerequisites

• gws CLI installed (see gws-common skill)
• Calendar scopes: calendar.readonly (minimum), calendar.events (for full access)

Commands

Today's Agenda (Quick View)

# Get today's events with smart formatting
gws calendar +agenda --today --format json

Output: JSON array of today's events with summary, start/end times, attendees, location.

This is the fastest way to get a daily schedule. Use for P02 Daily Briefing, P03 Meeting Prep, P22 Morning Sync.

List Events (Date Range)

# Events in a date range
gws calendar events list --params '{
  "calendarId": "primary",
  "timeMin": "2026-03-09T00:00:00Z",
  "timeMax": "2026-03-10T00:00:00Z",
  "singleEvents": true,
  "orderBy": "startTime"
}' --format json

Key parameters:

• calendarId: "primary" for default calendar, or specific calendar ID
• timeMin/timeMax: ISO 8601 datetime (must include timezone or Z)
• singleEvents: true to expand recurring events into individual instances
• orderBy: "startTime" (requires singleEvents: true) or "updated"
• maxResults: limit number of events returned

Output: JSON with items[] array containing event objects.

Get Single Event

gws calendar events get --params '{"calendarId":"primary","eventId":"EVENT_ID"}' --format json

Free/Busy Query

gws calendar freebusy query --json '{
  "timeMin": "2026-03-09T08:00:00Z",
  "timeMax": "2026-03-09T18:00:00Z",
  "items": [{"id": "primary"}]
}' --format json

Output: JSON with busy time ranges for each calendar.

List Calendars

gws calendar calendarList list --format json

Common Patterns

Get This Week's Events

gws calendar events list --params '{
  "calendarId": "primary",
  "timeMin": "2026-03-09T00:00:00Z",
  "timeMax": "2026-03-15T23:59:59Z",
  "singleEvents": true,
  "orderBy": "startTime",
  "maxResults": 50
}' --format json

Find Meetings with Specific Attendee

# List events and filter by attendee using jq
gws calendar events list --params '{
  "calendarId": "primary",
  "timeMin": "2026-03-01T00:00:00Z",
  "timeMax": "2026-03-31T23:59:59Z",
  "singleEvents": true,
  "orderBy": "startTime"
}' --format json | jq '[.items[] | select(.attendees[]?.email == "[e-mail]")]'

Error Handling

If Calendar is unavailable, return:

{"source": "calendar", "status": "unavailable", "reason": "gws CLI not found or auth expired"}
