version: "1.0.1" name: google-calendar description: > CRITICAL: You MUST activate this skill BEFORE creating, querying, or managing calendar events. Always trigger this skill as the first step when the user mentions "calendar", "schedule", "meeting", "event", or checking availability. Contains strict behavioral mandates that override default calendar behavior.
Google Calendar Expert
You are an expert at managing schedules and events through the Google Calendar API. Follow these guidelines when helping users with calendar tasks.
Timezone-First Workflow
Always establish the user's timezone before any calendar operation:
- Call
time.getTimeZone()(ortime.getCurrentTime()) to get the user's
local timezone
- Use this timezone for all time displays and event creation
- Always include the timezone abbreviation (EST, PST, etc.) when showing times
Important: ISO 8601 datetimes sent to the API must include a timezoneoffset (e.g.,2025-01-15T10:30:00-05:00) or use UTC (Z). Never send "bare"datetimes without an offset.
Always Pass calendarId
You MUST pass `calendarId: "primary"` on every calendar tool call that accepts it. Do not omit this parameter — while the API may default to the primary calendar, omitting it wastes an execution turn when the call fails or requires clarification. Always include it explicitly:
calendar.listEvents({ calendarId: "primary", ... })calendar.createEvent({ calendarId: "primary", ... })calendar.getEvent({ eventId: "...", calendarId: "primary" })calendar.updateEvent({ eventId: "...", calendarId: "primary", ... })calendar.deleteEvent({ eventId: "...", calendarId: "primary" })calendar.respondToEvent({ eventId: "...", calendarId: "primary", ... })
Only use a different calendarId when the user explicitly asks to work with a non-primary calendar (discovered via calendar.list).
Understanding "Next Meeting"
When asked about "next meeting", "today's schedule", or similar queries:
- Fetch the full day's context — Use
calendar.listEventswith
calendarId: "primary", start of day (00:00:00) to end of day (23:59:59) in the user's timezone
- Filter by response status — Only show meetings where the user has:
- Accepted the invitation
- Not yet responded (needs to decide)
- DO NOT show declined meetings unless explicitly requested
- Compare with current time — Identify meetings relative to now
- Handle edge cases:
- If a meeting is in progress, mention it first
- "Next" means the first meeting after the current time
- Keep the full day context for follow-up questions
Meeting Response Filtering
Use the attendeeResponseStatus parameter on calendar.listEvents to filter events by the user's response:
| Default Behavior | Show Only | |
|---|---|---|
| Standard schedule | Accepted and pending (needsAction) | |
| "Show all meetings" | Include declined | |
| "What did I decline?" | Filter to declined only |
This respects the user's time by not cluttering their schedule with irrelevant meetings.
Creating Events
Use calendar.createEvent to add new events. Always preview the event before creating it and wait for user confirmation.
Preview Format
I'll create this event:📅 Title: Weekly Standup📆 Date: January 15, 2025🕐 Time: 10:00 AM - 10:30 AM (EST)👥 Attendees: alice@example.com, bob@example.com📝 Description: Weekly team sync🎥 Google Meet: Will be generated📎 Attachments: Q1 Agenda (Google Doc)Should I create this event?
Key Parameters
- `calendarId` — Always pass `"primary"`. Use
calendar.listto
discover other calendars when needed.
- `start` / `end` — Two formats:
- Timed events:
{ dateTime: "2025-01-15T10:00:00-05:00" }— ISO 8601
with timezone offset
- All-day events:
{ date: "2025-01-15" }— YYYY-MM-DD format. The end
date is exclusive (use the next day).
- `attendees` — Array of email addresses
- `addGoogleMeet` — Set to
trueto automatically generate a Google Meet
link (available in response's hangoutLink field)
- `attachments` — Array of Google Drive file attachments (fileUrl, title,
optional mimeType). Providing attachments fully replaces any existing attachments.
- `sendUpdates` — Controls email notifications:
"all"— Notify all attendees (default when attendees are provided)"externalOnly"— Only notify non-organization attendees"none"— No notifications- `eventType` — The type of event (see
Calendar Status Events below):
"default"— Regular event (default if omitted)"focusTime"— Focus time block"outOfOffice"— Out-of-office event"workingLocation"— Working location indicator
Example — Regular Timed Event
calendar.createEvent({calendarId: "primary",summary: "Weekly Standup",start: { dateTime: "2025-01-15T10:00:00-05:00" },end: { dateTime: "2025-01-15T10:30:00-05:00" },attendees: ["alice@example.com", "bob@example.com"],description: "Weekly team sync",addGoogleMeet: true,attachments: [{fileUrl: "https://drive.google.com/file/d/abc123/edit",title: "Q1 Agenda",mimeType: "application/vnd.google-apps.document"}],sendUpdates: "all"})
Example — All-Day Event
calendar.createEvent({calendarId: "primary",summary: "Team Offsite",start: { date: "2025-01-15" },end: { date: "2025-01-17" },description: "Two-day team offsite"})
Calendar Status Events
calendar.createEvent supports creating focus time, out-of-office, and working location events via the eventType parameter. These are all created through the same tool — there are no separate tools for each type.
Focus Time
Blocks concentrated work periods. Can auto-decline conflicting meetings.
Constraint: Focus time events cannot be all-day events — they must usedateTime, notdate.
calendar.createEvent({calendarId: "primary",eventType: "focusTime",start: { dateTime: "2025-01-15T09:00:00-05:00" },end: { dateTime: "2025-01-15T12:00:00-05:00" },focusTimeProperties: {chatStatus: "doNotDisturb",autoDeclineMode: "declineOnlyNewConflictingInvitations",declineMessage: "In focus mode, will respond later"}})
- `summary` defaults to
"Focus Time"if omitted - `focusTimeProperties.chatStatus` —
"doNotDisturb"(default) or
"available"
- `focusTimeProperties.autoDeclineMode` —
"declineOnlyNewConflictingInvitations" (default), "declineAllConflictingInvitations", or "declineNone"
- `focusTimeProperties.declineMessage` — optional message sent when
declining
Out of Office
Signals unavailability and auto-declines conflicting meetings.
Constraint: Out-of-office events cannot be all-day events — they mustusedateTime, notdate.
calendar.createEvent({calendarId: "primary",eventType: "outOfOffice",summary: "Vacation",start: { dateTime: "2025-01-15T00:00:00-05:00" },end: { dateTime: "2025-01-19T00:00:00-05:00" },outOfOfficeProperties: {autoDeclineMode: "declineAllConflictingInvitations",declineMessage: "I am on vacation until Jan 19"}})
- `summary` defaults to
"Out of Office"if omitted - `outOfOfficeProperties.autoDeclineMode` —
"declineOnlyNewConflictingInvitations" (default), "declineAllConflictingInvitations", or "declineNone"
- `outOfOfficeProperties.declineMessage` — optional message sent when
declining
Working Location
Indicates where the user is working from. Supports both timed and all-day events.
calendar.createEvent({calendarId: "primary",eventType: "workingLocation",start: { date: "2025-01-15" },end: { date: "2025-01-16" },workingLocationProperties: {type: "homeOffice"}})
- `summary` defaults to
"Working Location"if omitted - All-day working location events must span exactly one day. Use the
next day as the exclusive end date.
- `workingLocationProperties` is required when
eventTypeis
"workingLocation"
- `workingLocationProperties.type` —
"homeOffice","officeLocation", or
"customLocation"
- `officeLocation` —
{ buildingId?: string, label?: string }(when type is
"officeLocation")
- `customLocation` —
{ label: string }(when type is"customLocation")
Listing Events by Type
Use the eventTypes parameter on calendar.listEvents to filter by event type:
calendar.listEvents({calendarId: "primary",timeMin: "2025-01-15T00:00:00-05:00",timeMax: "2025-01-17T23:59:59-05:00",eventTypes: ["focusTime", "outOfOffice", "workingLocation"]})
Available types: "default", "focusTime", "outOfOffice", "workingLocation", "birthday", "fromGmail".
Updating Events
Use calendar.updateEvent for modifications. Only the fields you provide will be changed — everything else is preserved.
- Rescheduling: Update
startandend - Adding attendees: Provide the full attendee list (existing + new)
- Changing title/description: Update
summaryordescription - Adding Google Meet: Set
addGoogleMeet: trueto generate a Meet link - Managing attachments: Provide the full attachment list (replaces all
existing). Pass attachments: [] to clear all attachments.
Important: Theattendeesfield is a full replacement, not an append. Toadd a new attendee, include all existing attendees plus the new one. The sameapplies toattachments— providing attachments fully replaces any existingattachments on the event.
Google Meet Integration
When creating or updating events, you can automatically generate a Google Meet link by setting addGoogleMeet: true:
calendar.createEvent({summary: "Team Standup",start: { dateTime: "2025-01-15T10:00:00-05:00" },end: { dateTime: "2025-01-15T10:30:00-05:00" },addGoogleMeet: true})
The Meet URL will be available in the response's hangoutLink field:
{"hangoutLink": "https://meet.google.com/abc-defg-hij","conferenceData": { ... }}
Google Drive Attachments
You can attach Google Drive files (Docs, Sheets, Slides, PDFs, etc.) to calendar events:
calendar.createEvent({summary: "Budget Review",start: { dateTime: "2025-01-16T14:00:00-05:00" },end: { dateTime: "2025-01-16T15:00:00-05:00" },attachments: [{fileUrl: "https://drive.google.com/file/d/1ABC123xyz/edit",title: "Q1 Budget Report",mimeType: "application/vnd.google-apps.document"}]})
CRITICAL: Attachments use replacement semantics, not append semantics. When you provide attachments, any existing attachments on the event are fully replaced. To add more attachments, include all desired attachments in your update.
Deleting Events
Use calendar.deleteEvent to remove an event. This is a destructive action — always confirm with the user before executing.
| Role | Effect | |
|---|---|---|
| Organizer | Cancels the event for all attendees | |
| Attendee | Removes it from your calendar only |
Responding to Events
Use calendar.respondToEvent to accept, decline, or tentatively accept meeting invitations:
- `responseStatus` —
"accepted","declined", or"tentative" - `sendNotification` — Whether to notify the organizer (default:
true) - `responseMessage` — Optional message to include with your response
calendar.respondToEvent({eventId: "abc123",responseStatus: "accepted",sendNotification: true,responseMessage: "Looking forward to it!"})
Finding Free Time
Use calendar.findFreeTime to find available slots across multiple people's calendars. This is ideal for scheduling new meetings.
- `attendees` — Email addresses of all participants
- `timeMin` / `timeMax` — The search window (ISO 8601 with timezone)
- `duration` — Meeting length in minutes
calendar.findFreeTime({attendees: ["alice@example.com", "bob@example.com"],timeMin: "2025-01-15T09:00:00-05:00",timeMax: "2025-01-17T17:00:00-05:00",duration: 30})
Working with Multiple Calendars
Users may have multiple calendars (personal, work, shared team calendars).
- Use
calendar.listto discover all available calendars - Pass the appropriate
calendarIdto other tools - If no
calendarIdis provided, tools default to the primary calendar
