Calendar Skill

View agenda, create and manage events, check availability, and manage calendars using the gws CLI.

Auth Approach

Do NOT check authentication upfront. Just run the command. If it fails with an auth error (exit code 2), see the Self-Healing section for diagnostics.

Tool Preference

All operations use the gws CLI directly. No wrapper scripts.

Helper commands (prefixed with +): Use for common operations. These handle timezone detection, formatting, and attendee management automatically.
Raw API calls: Use when no helper exists. Pass parameters via --params '<JSON>' and request bodies via --json '<JSON>'. Resource paths are space-separated (e.g., gws calendar events list).

Always prefer + helpers when one exists for the operation.

Operations — Tier 1 (Read)

View Agenda

gws calendar +agenda
gws calendar +agenda --today
gws calendar +agenda --tomorrow
gws calendar +agenda --week
gws calendar +agenda --days 3
gws calendar +agenda --calendar 'Work'
gws calendar +agenda --today --timezone America/New_York

Get Event Details

gws calendar events get --params '{"calendarId": "primary", "eventId": "<id>"}'

List Events (Filtered)

gws calendar events list --params '{"calendarId": "primary", "timeMin": "<iso>", "timeMax": "<iso>"}'

Check Availability

gws calendar freebusy query --json '{"timeMin": "<iso>", "timeMax": "<iso>", "items": [{"id": "primary"}]}'

Operations — Tier 2 (Write)

Create Event

gws calendar +insert --summary '<title>' --start '<iso>' --end '<iso>'
gws calendar +insert --summary '<title>' --start '<iso>' --end '<iso>' --location '<place>'
gws calendar +insert --summary '<title>' --start '<iso>' --end '<iso>' --attendee [email protected] --attendee [email protected]
gws calendar +insert --summary '<title>' --start '<iso>' --end '<iso>' --meet
gws calendar +insert --summary '<title>' --start '<iso>' --end '<iso>' --description '<text>'

Quick-Add Event

gws calendar events quickAdd --params '{"calendarId": "primary", "text": "<natural language>"}'

Update Event

gws calendar events patch --params '{"calendarId": "primary", "eventId": "<id>"}' --json '<event-json>'

Move Event

gws calendar events move --params '{"calendarId": "primary", "eventId": "<id>", "destination": "<calId>"}'

Operations — Tier 3 (Manage)

Delete Event

gws calendar events delete --params '{"calendarId": "primary", "eventId": "<id>"}'

Confirm with the user before deleting.

List Calendars

gws calendar calendarList list

Create / Delete Calendar

gws calendar calendars insert --json '{"summary": "<name>"}'
gws calendar calendars delete --params '{"calendarId": "<id>"}'

Confirm with the user before deleting a calendar.

Access Control (ACL)

gws calendar acl list --params '{"calendarId": "<id>"}'
gws calendar acl insert --params '{"calendarId": "<id>"}' --json '{"role": "reader", "scope": {"type": "user", "value": "<email>"}}'
gws calendar acl delete --params '{"calendarId": "<id>", "ruleId": "<ruleId>"}'

Common Calendar Recipes

See calendar-recipes.md

Self-Healing

When a command fails:

Auth Errors (exit code 2)

Check if gws is available and authenticated:

which gws && gws auth status

If gws is not installed or not authenticated, tell the user:

"The gws CLI is not installed or not authenticated. Install and configure it: https://github.com/googleworkspace/cli"

Other Errors

Check the command's help: gws calendar <command> --help
Inspect the API schema: gws schema calendar.<resource>.<method>
Use --dry-run to preview requests without executing
Exit codes: 0=success, 1=API error, 2=auth error, 3=validation, 4=discovery, 5=internal
Validation errors (exit 3): check --params JSON syntax and required fields

Behavioral Guidelines

Prefer + helpers (+agenda, +insert) over raw API calls when available.
Default to "calendarId": "primary" in --params unless the user specifies a different calendar.
Use ISO 8601 / RFC 3339 format for all timestamps (e.g., 2026-03-18T14:00:00-04:00).
Use --dry-run to preview commands before executing destructive operations.
Confirm with the user before deleting events or calendars.
When creating events with +insert, include timezone offset in the ISO timestamp.
When the user asks "what's on my calendar" or "meetings today", use +agenda --today.
When the user gives a natural-language event description, prefer quickAdd for simple cases and +insert for structured cases.
