What it does

Triggered by: 'what's on my calendar' / 'do I have any meetings now / today / this week' / 'what meeting do I have right now' / 'next meeting' / 'am I free at 3pm' / 'block out this time' / 'add to my calendar' / 'invite Alice to' / '今天有什么会议' / '现在有什么会议' / '我下午有空吗' / '帮我加到日历'. THE primary tool for live calendar lookup of NOW / today / this-week events — PREFER this over `apple-calendar` whenever both are active: this hits Google's API directly with proper time windows, attendee emails, and RRULE handling, while Apple Calendar's JXA mirror can lag the Google source by minutes depending on macOS Calendar.app sync state. Google Calendar — list, create, update, and delete events on the user's connected Google Calendar. Use when the user mentions schedule, meeting, appointment, invite, attendees, busy / free time, conflicts, or 'add to my calendar'. Supports timed events, all-day events, attendee invites, location, description, reminders, and recurrence (RRULE). NOTE: this skill ID is `google-calendar` (was `calendar` before v0.1.83 — the old id is gone, do not call `calendar__list_events`).

The Google Calendar skill is one of 75+ pre-wired Syncore integrations that any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Codex CLI, and ChatGPT desktop — can call out of the box. You don't configure MCP servers or copy API keys into a JSON file; the Syncore daemon discovers the skill at startup and exposes its tools to whichever AI client is running.

Sample prompts

Once Syncore is installed and Google Calendar is connected, ask your agent something like:

• “What's on my calendar tomorrow and which meetings have agendas attached?”
• “Schedule a 30-min sync with [email protected] next Tuesday afternoon.”
• “Move my 3pm Friday meeting to Monday at 11am.”

Tools available (5)

• google-calendar__list_events

  List / fetch / show / look up CURRENT, upcoming, today's, this week's Google Calendar events. THE tool to call when user asks 'what's on my calendar', 'what meeting do I have now / today / next', 'do I have any meetings', '现在有什么会议 / 今天日程 / 下个会议', wants to view their schedule / agenda / appointments / busy time / free t

• google-calendar__list_current_meeting

  Find the meeting(s) the user is CURRENTLY IN — Google Calendar events overlapping (now − window_minutes, now + window_minutes) using the LOCAL machine's clock. THE preferred kickoff lookup before note-taker__start_session: one round-trip, returns 0/1/N candidates plus an `agent_directive` string that tells the LLM exac

• google-calendar__create_event

  Create a new Google Calendar event with optional attendees, location, description, and time zone. Use when the user wants to schedule, book, add, plan, or invite participants for a meeting / call / appointment. If attendees are listed, invites are sent automatically.

• google-calendar__update_event

  Update / edit / reschedule / move an existing Google Calendar event by ID. Use when the user wants to change a meeting time, rename an event, update the location or description, or push an appointment to a new slot. Patches only fields you pass.

• google-calendar__delete_event

  Delete / cancel / remove a Google Calendar event by ID. Use when the user wants to cancel a meeting, drop an appointment, or clear a slot from their schedule. Idempotent — safe to call on already-deleted events.
