google-calendar
This skill wraps the Google Calendar API to list, add, update, and delete events via `https://www.googleapis.com/calendar/v3`. It requires and reads `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET`, `GOOGLE_REFRESH_TOKEN`, uses `https://oauth2.googleapis.com/token`, writes `~/.config/google-calendar/secrets.env`, and includes setup commands like `python3 -m google_calendar.auth`.
