    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
    A derived TradeBasis asking-price market average. Supply odometerMiles plus either vin or all of year, make, model and trim. Ask the user for missing details; never invent vehicle identity or mileage. VIN-assisted decoding may still require a confirmed trim, fuelType or bodyStyle. If supplied identity conflicts with the VIN, ask the user to verify the VIN and conflicting fields; do not choose silently or retry unchanged. Omit market for nationwide US. Not a trade-in offer or completed-sale value.

    Annotations the server declares

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

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.
