Google Calendar Skill

Overview

This skill provides a thin wrapper around the Google Calendar REST API. It lets you: - list upcoming events (optionally filtered by time range or query) - add a new event with title, start/end time, description, location, and attendees - update an existing event by its ID - delete an event by its ID

The skill is implemented in Python (scripts/google_calendar.py). It expects the following environment variables to be set (you can store them securely with openclaw secret set):

GOOGLE_CLIENT_ID=…
GOOGLE_CLIENT_SECRET=…
GOOGLE_REFRESH_TOKEN=…   # obtained after OAuth consent
GOOGLE_CALENDAR_ID=primary   # or the ID of a specific calendar

The first time you run the skill you may need to perform an OAuth flow to obtain a refresh token – see the Setup section below.

Commands

google-calendar list [--from <ISO> --to <ISO> --max <N>]
google-calendar add   --title <title> [--start <ISO> --end <ISO>]
                     [--desc <description> --location <loc> --attendees <email1,email2>]
google-calendar update --event-id <id> [--title <title> ... other fields]
google-calendar delete --event-id <id>

All commands return a JSON payload printed to stdout. Errors are printed to stderr and cause a non‑zero exit code.

Setup

  1. Create a Google Cloud project and enable the Google Calendar API.
  2. Create OAuth credentials (type Desktop app). Note the client_id and client_secret.
  3. Run the helper script to obtain a refresh token: bash GOOGLE_CLIENT_ID=… GOOGLE_CLIENT_SECRET=… python3 -m google_calendar.auth It will open a browser (or print a URL you can open elsewhere) and ask you to grant access. After you approve, copy the refresh_token it prints.
  4. Store the credentials securely: bash openclaw secret set GOOGLE_CLIENT_ID <value> openclaw secret set GOOGLE_CLIENT_SECRET <value> openclaw secret set GOOGLE_REFRESH_TOKEN <value> openclaw secret set GOOGLE_CALENDAR_ID primary # optional
  5. Install the required Python packages (once): bash pip install --user google-auth google-auth-oauthlib google-api-python-client

How it works (brief)

The script loads the credentials from the environment, refreshes the access token using the refresh token, builds a service = build('calendar', 'v3', credentials=creds), and then calls the appropriate API method.

Note: This skill does not require a GUI; it works entirely via HTTP calls, so it is suitable for headless servers.
