Google Calendar Integration

This skill provides Google Calendar access using the same OAuth credentials as Gmail.

Prerequisites

• OAuth credentials already set up (shared with Gmail skill)
• Calendar API enabled in Google Cloud Console
• Token includes calendar scopes (calendar.readonly, calendar.events)

Available Scripts

All scripts are in tools/google-calendar/scripts/ and require --credentials ./credentials.json.

List Calendars

uv run python tools/google-calendar/scripts/list_calendars.py --credentials ./credentials.json

Search Events

Search for events by text query or time range:

# Search by text
uv run python tools/google-calendar/scripts/search_events.py "meeting" --credentials ./credentials.json

# Search by date range (use YYYY-MM-DD format)
uv run python tools/google-calendar/scripts/search_events.py --start "YYYY-MM-DD" --end "YYYY-MM-DD" --credentials ./credentials.json

# Combine text and date
uv run python tools/google-calendar/scripts/search_events.py "standup" --start "YYYY-MM-DD" --credentials ./credentials.json

Check Availability (Free/Busy)

Find busy periods in a time range:

uv run python tools/google-calendar/scripts/find_busy.py --start "YYYY-MM-DDTHH:MM:00" --end "YYYY-MM-DDTHH:MM:00" --credentials ./credentials.json

Note: This script may have issues with datetime formatting. Use search_events.py as a more reliable way to check what's on the calendar.

Create Event

Create a new calendar event:

uv run python tools/google-calendar/scripts/create_event.py \
  --summary "Team Standup" \
  --start "YYYY-MM-DDTHH:MM:00" \
  --end "YYYY-MM-DDTHH:MM:00" \
  --credentials ./credentials.json

# With optional fields
uv run python tools/google-calendar/scripts/create_event.py \
  --summary "Product Demo" \
  --start "YYYY-MM-DDTHH:MM:00" \
  --end "YYYY-MM-DDTHH:MM:00" \
  --description "Demo of new features" \
  --location "Zoom" \
  --attendees "alice@example.com,bob@example.com" \
  --timezone "America/Los_Angeles" \
  --credentials ./credentials.json

Options:

• --summary (required): Event title
• --start (required): Start datetime in ISO format
• --end (required): End datetime in ISO format
• --description: Event description
• --location: Event location (e.g., "Zoom", "Conference Room A")
• --attendees: Comma-separated email addresses (sends invites automatically)
• --timezone: Timezone for the event (e.g., America/Los_Angeles, America/New_York, Europe/London)
• --calendar: Calendar ID (default: "primary")

Common Patterns

Check availability for a day

Use search_events.py with start and end dates to see all events:

uv run python tools/google-calendar/scripts/search_events.py --start "YYYY-MM-DD" --end "YYYY-MM-DD" --credentials ./credentials.json

Schedule a meeting

1. Check calendar with search_events.py to find free slots
2. Create event with create_event.py

Review upcoming week

uv run python tools/google-calendar/scripts/search_events.py --start "TODAY" --end "NEXT_WEEK" --credentials ./credentials.json

(Replace TODAY/NEXT_WEEK with actual dates)
