What this skill does
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/googlecalendar.py). It expects the following environment variables to be set (you can store them securely with openclaw secret set): 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 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 clientid and clientsecret. 3. Run the helper script to obtain a refresh token: It will open a browser (or print a URL you can open elsewhere) and ask you to grant access. After you approve, copy the refreshtoken it prints. 4. Store the credentials securely: 5. Install the required Python packages (once): 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.
