    Description, as the server wrote it
    The cheapest one-way fare seen on each day of the next three months or so from one city to another in Europe or Southeast Asia (non-stop flights), or on a long flight between a big airport outside the region and one of its cities (any stops): each day's price, its age and airline, the cheapest by month, the airlines with how many days they fly it and their cabin bag rule, the cheapest the other way, and a link to the route's page on faredice.com.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Every city one city in Europe or Southeast Asia flies to non-stop over the next three months or so (or that a big airport outside the region flies to, any stops), cheapest first: each with its cheapest fare, the day, its age and airline, how many days have fares and the airlines, and links to each route's page on faredice.com.

    Why it is in this group

    • The name "find_trips" says "find": a word for reading.
    Description, as the server wrote it
    Finds cheap trips through several cities and countries in Europe or Southeast Asia, strung from non-stop one-way fares seen in the last few days: you give a start city (or a home airport outside the region: the trip then starts with a flight from the nearest big airport we have fares from), a window for the first flight, how many places and nights in each, and a flight budget, and optionally the kinds of place (beaches, islands, capitals ...), countries to keep to or skip and cities per country; it picks the cities. Returns the cheapest three trips, each with its flights, fare ages, cabin-bag notes and a link to the trip on faredice.com.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

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.
