Can't be undone 1Claude Code: ask
  • request_trip_helpSends one email to the person's own address.No findings

    Why it is in this group

    • The name "request_trip_help" says "request": a word for a change.
    • The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
    Description, as the server wrote it
    Sends one email to the person's own address. Their click in that email confirms the request; only then does it reach a Fantasize cruise specialist, who replies to them by email to help plan and book the trip. Free; no account is created and nothing is charged. Takes the trip they want in a sentence or two, and optionally dates, travellers, budget, home city and the sailing ids they looked at.

    Description, as the server wrote it
    Judge a price someone was quoted or already paid for one sailing: whether it is low, typical or high against that sailing's usual price for the cabin, today's listed fare beside it, the lowest fare read in 120 days, a plain one-paragraph answer to quote, and watch_url where the person can be emailed if the fare drops below their price. Name the sailing by sailing_id, a fantasize.net /cruise/ link, or ship plus depart_date.

    Description, as the server wrote it
    Fantasize's Cruise Fare Index: how the price of the same cruises moves night to night, from our own nightly pricing of every sailing (each sailing compared only with its own earlier price, so new sailings and sell-outs never move it). Returns the overall level and its change, and the same by cruise company (with stock ticker), cruise line, region and months to departure, plus the cruise companies' latest press releases. Name a group (e.g. "Royal Caribbean Group", "Alaska", "3-6 months out") for its daily series.

    Today's report of balcony and suite cabins on cruises leaving North American ports within about 21 days, each measured against the book-ahead price for the same ship, grade and length (rebuilt every morning). Filter by departure port or region. Some late fares are dearer than booking ahead; those show a negative percent.

    Report a problem you found while using these tools: a price that does not match the booking page (wrong_price), a sailing that cannot be bought (not_for_sale), a wrong route or ports (wrong_itinerary), a book_url that does not open the sailing (broken_link), results that miss or do not fit the request (irrelevant_results, missing_sailings), or duplicates.

    Description, as the server wrote it
    Accepts the request in plain words (q) or as fields. Searches every sailing Fantasize tracks (23 cruise lines, ~30,000 sailings, priced every night) by region, dates, departure port, ports visited, line, length, cabin and budget. Returns up to 25 sailings with the price per person (taxes and port fees in), per night and for a cabin of two, every cabin grade's price, whether the fare is low, typical or high against that sailing's usual price, the ports of call, and book_url - a link the person opens to book that exact sailing. Default ranking is best_value (furthest below its usual price).

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.
