Google Calendar Skill - Calendar & Events

Read, create, and manage Google Calendar events. View agenda, create meetings, check availability.

CRITICAL: Event Creation Confirmation Required

Before creating ANY calendar event, you MUST get explicit user confirmation.

When the user asks to create an event:

1. First, show them the complete event details:
   • Title
   • Start time
   • End time
   • Location (if any)
   • Attendees (if any)
2. Ask: "Do you want me to create this event?"
3. ONLY run the create command AFTER the user explicitly confirms

First-Time Setup

This skill reuses credentials from gmail-skill if available. Otherwise:

1. Go to Google Cloud Console
2. Enable Google Calendar API (APIs & Services -> Library)
3. Use existing OAuth client or create new Desktop app client
4. Download JSON -> save as ~/.claude/skills/gcal-skill/credentials.json

Then just run any command - browser opens for auth.
