Measured tools (23)

• create_plan

  Creates a new saved lesgooo group plan with the user as its first participant. Use when the user wants to start planning something new. Returns the shareable plan links and the participant's private credentials (participant_id, participant_token) needed for later changes. Title and name are optional. Sends no invitations or notifications.

  Parameters:

  • title — string — User-supplied short plan name (max 120 chars). Omitted when unknown; temporary Event label until collected after the requested action.
  • your_name — string — User-supplied participant name (max 80 chars). Omitted when unknown; temporary Organizer participant until their name is collected after the requested action.
  • request_id — string — Optional UUID v4 for atomic creation. An identical UUID and identical fields (including omissions) replay the same creation; a changed payload is rejected.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• get_plan read-only

  Reads a saved plan: title, Event details, participants with their all-day and exact-time availability and RSVP answers, best dates and shared free-time windows, suggested places with votes, and the currency. Use when the user shares a plan link or asks about a plan's current state. time_zone resolves today's date; since returns changes after an earlier server_time.

  Parameters:

  • plan (required) — string — Saved plan link (e.g. https://lesgooo.fun/ab12/when) or its 4-character plan ID. Links without a plan ID (e.g. https://lesgooo.fun/when) are unsaved local drafts and are not accepted.
  • since — string — Optional ISO timestamp (server_time from an earlier get_plan).
  • time_zone — string — The user's IANA time zone, e.g. Europe/Prague.
  • include_all_dates — boolean — For calendar UI: return all dates within the existing bounded read budget, instead of the concise first 60 per person.

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• join_plan destructive

  Adds the user to a saved plan under their name, or selects the existing participant with that name, and returns that person's private credentials. Use when the user wants to take part in an existing plan or act as a specific participant in it. With existing credentials it renames that same participant instead. It does not verify identity or grant organizer rights.

  Parameters:

  • plan (required) — string — Saved plan link (e.g. https://lesgooo.fun/ab12/when) or its 4-character plan ID. Links without a plan ID (e.g. https://lesgooo.fun/when) are unsaved local drafts and are not accepted.
  • name (required) — string — The person's name as the group knows them (max 80 chars).
  • selection — string — Without credentials: auto matches or adds; existing never adds; new never takes another person's matching name. Default auto.
  • participant_id — string — From create_plan or join_plan.
  • participant_token — string — From create_plan or join_plan.
  • existing_participant_id — string — Exact existing participant ID from get_plan or received user UI selection; requires selection=existing and matching name. No rename.

  Hints: read-only no · destructive yes · idempotent yes · open-world yes

• set_availability destructive

  Changes one participant's availability: all-day dates and/or exact free-time windows (ISO start and end with offset, plus the IANA time_zone). mode=add merges, remove subtracts, replace overwrites. Use when the user says which days or hours they are or are no longer free. It does not set the agreed Event date or an RSVP.

  Parameters:

  • plan (required) — string — Saved plan link (e.g. https://lesgooo.fun/ab12/when) or its 4-character plan ID. Links without a plan ID (e.g. https://lesgooo.fun/when) are unsaved local drafts and are not accepted.
  • participant_id (required) — string — From create_plan or join_plan.
  • participant_token (required) — string — From create_plan or join_plan.
  • dates (required) — array
  • mode — string — add/remove change supplied days/windows; replace is a full replacement when time_slots is supplied. Default replace (legacy all-day behavior).
  • time_zone — string — The user's IANA time zone, e.g. Europe/Prague.
  • time_slots — array — Optional exact windows. For hours-only changes pass dates=[] and mode=add/remove; replace changes the entire availability. End is exclusive.

  Hints: read-only no · destructive yes · idempotent yes · open-world yes

• set_rsvp destructive

  Records whether the participant is coming to the plan's Event: yes, no, or clear to remove the answer. For a repeating event it answers one occurrence (the next one by default, or occurrence_date). Use when the user says they are or are not attending.

  Parameters:

  • plan (required) — string — Saved plan link (e.g. https://lesgooo.fun/ab12/when) or its 4-character plan ID. Links without a plan ID (e.g. https://lesgooo.fun/when) are unsaved local drafts and are not accepted.
  • participant_id (required) — string — From create_plan or join_plan.
  • participant_token (required) — string — From create_plan or join_plan.
  • status (required) — string
  • occurrence_date — string — Repeating events only: the date of the occurrence to answer for.

  Hints: read-only no · destructive yes · idempotent yes · open-world yes

• add_place

  Suggests a place for the group to vote on (Where). By default it searches Google Places and returns up to five candidates without saving (status needs_selection); calling it again with the chosen google_place_id saves the place with its official details, map link and photo. source=manual saves a supplied name, address or link without a lookup. Duplicates are merged. Use when the user proposes a venue or destination.

  Parameters:

  • plan (required) — string — Saved plan link (e.g. https://lesgooo.fun/ab12/when) or its 4-character plan ID. Links without a plan ID (e.g. https://lesgooo.fun/when) are unsaved local drafts and are not accepted.
  • participant_id (required) — string — From create_plan or join_plan.
  • participant_token (required) — string — From create_plan or join_plan.
  • name (required) — string — Requested place name, including accents (max 300 chars). A selected Google result supplies its official name.
  • link — string — Optional link to any other page about the place (http/https), instead of google_maps_url.
  • query — string — Optional Google autocomplete query including the known city/address (max 160 chars); otherwise name/address are used.
  • source — string — Default auto uses Google first. Manual explicitly saves the supplied name/address/link without a paid lookup.
  • address — string — Optional address (max 500 chars).
  • google_maps_url — string — Optional Google Maps link (google.com/maps or maps.app.goo.gl). Links with coordinates (…/@50.08,14.42,…) also show a map preview.
  • google_place_id — string — Exact place ID from returned Google candidates; official details are loaded server-side (max 160 chars).
