Calendar Operations via gog CLI

Interact with Google Calendar using the gog CLI tool (gog calendar or alias gog cal).

Prerequisites

Verify gog is available and authenticated:

gog calendar calendars

If authentication fails, inform the user to run gog auth add <email> --services calendar first.

Core Principles

• Always use --json when parsing output programmatically (e.g., extracting event IDs). Use human-readable output when displaying schedules to the user.
• Use --dry-run before creating, updating, or deleting events. Preview the action, then execute after user confirmation.
• Use --no-input to prevent interactive prompts.
• Calendar ID defaults to primary for most commands. Use gog calendar calendars to discover other calendar IDs.

Safety Rules

• Never create, update, or delete events without --dry-run preview and user confirmation.
• Default --send-updates=none when creating/updating to avoid surprise notifications. Ask the user if they want to notify attendees.
• When listing events, default to --max=10 to keep output manageable.
• For recurring event updates, clarify scope (single/future/all) with the user before proceeding.
