Can't be undone 1Claude Code: ask
  • create_group_eventCreate a Lucie group event (a poll) for several participants, pre-filled with candidate times when everyone is free (the intersection of their availability).No findings

    Why it is in this group

    • The name "create_group_event" says "create": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.
    Description, as the server wrote it
    Create a Lucie group event (a poll) for several participants, pre-filled with candidate times when everyone is free (the intersection of their availability). Returns a vote link to share: participants pick which proposed times work, and people WITHOUT a Lucie handle can vote manually too. This is a write (creates a poll) but sends no emails and touches no calendars. Confirm the title, participants, and duration with the organizer before creating. Note: agent group scheduling is a Sync Pro feature — the organizer's email must be on Sync Pro (or a Lucie Membership).

Changes things 2Claude Code: ask
  • book_group_meetingConfirm a group meeting at a specific time across several Lucie hosts (by @handle), creating ONE shared Google Calendar event with everyone invited.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Confirm a group meeting at a specific time across several Lucie hosts (by @handle), creating ONE shared Google Calendar event with everyone invited. YOU (the connector's owner) are the organizer and host the event on your calendar — no organizer handle needed. This is a real write: it re-verifies every participant (you included) is free at that instant and refuses if anyone isn't — so it never double-books. Always call find_group_times first and copy an exact common-slot start. Before calling, confirm the time (in each person's zone), the participants, the title, and the reason. Requires you to be on Sync Pro (or a Lucie Membership) via your personal connector; everyone must have a live booking page.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Book a confirmed meeting on a Lucie Sync host's calendar at a specific start time. This is a real write: it creates a calendar event and emails both the host and the booker. Always call check_availability first and use one of the open slots it returns. Before calling, (1) show the booker the specific date/time you're about to book — in their own time zone — and get their explicit confirmation, and (2) collect their name, email, AND a brief reason for the meeting (ask for the reason if not given; it's required and shared with the host).

  • check_availabilityReturn the open meeting slots a Lucie Sync host offers, plus their booking rules (durations offered, minimum notice, how far ahead you can book, buffer between meetings).No findings

    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Return the open meeting slots a Lucie Sync host offers, plus their booking rules (durations offered, minimum notice, how far ahead you can book, buffer between meetings). Returns only bookable slots and policy — never the host's raw calendar. Use this to find a time before proposing one to the user. Slots are absolute instants (ISO-8601 UTC). Pass the booker's viewerTimeZone so times display in THEIR local zone — the booker should never have to do time-zone math.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: true
  • find_group_timesGiven several Lucie hosts (by @handle), return the meeting times when ALL of them are free — the intersection of their availability — for a meeting of the given length.No findings

    Why it is in this group

    • The name "find_group_times" says "find": a word for reading.
    Description, as the server wrote it
    Given several Lucie hosts (by @handle), return the meeting times when ALL of them are free — the intersection of their availability — for a meeting of the given length. Read-only: never books, never exposes anyone's raw calendar (only the shared open slots). Use it to propose a group time. Times are absolute instants; pass viewerTimeZone so they show in the organizer's local zone.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
