## What it does

The skill handles the calendar chores: list calendars, view events over a date range, create, update and delete meetings, find an open slot for several attendees, and reply to invitations. You ask in plain language and the agent runs the call.

Two Python scripts sit behind it. `scripts/auth.py` manages login and logout, `scripts/gcal.py` does the actual work and auto-authenticates on first use if you are not logged in yet. Tokens go into the system keyring — Keychain on macOS, Credential Locker on Windows, Secret Service API on Linux — and expired ones get refreshed automatically.

One catch: a Google Workspace account is required. Personal Gmail accounts are not supported, so check which login you are on before wiring this up. Times use ISO 8601 with a timezone, and a non-primary calendar needs its ID from `list-calendars`, usually an email address.
