    Description, as the server wrote it
    Calculate total shipment volume (CBM / cubic metres and CFT / cubic feet), total weight, and how that cargo fits into standard shipping containers (20ft Standard, 40ft Standard, 40ft High Cube). Use this whenever someone asks how much space a shipment takes, how many cubic metres or CBM their boxes / pallets / cartons add up to, whether cargo will fit in a container, what container size they need, or how full a container will be. Accepts a list of items with length, width, height, weight and quantity in metric (cm, kg) or imperial (in, lb) units; returns total CBM, CFT, total weight, and per-container fill percentage with an overload flag.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    How many pallets fit in a given shipping container, truck trailer, rail wagon or air ULD. Use this whenever someone asks how many pallets (Euro 1200x800, standard 1200x1000, or US GMA 48x40) fit in a 20ft, 40ft, 40ft High Cube, 45ft, 53ft trailer or any other vessel. Returns the best single-layer floor count with pallets turned to their best orientation — a solved pallet-loading result, not length divided by length, so a 20ft holds 11 Euro pallets and a 40ft holds 25 — plus the double-stacked count with the load height that allows it, and how many the payload allows, which is what decides whether weight or floor space runs out first.

    Description, as the server wrote it
    Plan how one cargo size loads into a shipping container, truck trailer or rail wagon. Use this when someone asks how many of their boxes, cartons, crates or pallets (of a given size, and optionally weight) fit in a 20ft, 40ft, 40ft High Cube, 45ft, 53ft dry van, curtainsider or other vehicle, how many containers or trucks a quantity needs, or whether weight or space limits the load. Returns units per floor layer (mixed orientations), layers by interior height, units per load, whether space or payload binds, loads needed, utilisation, and a link to the same plan drawn on the web. One size per call; for several sizes, call once per size.

    Why it is in this group

    • The name "get_container_dimensions" says "get": a word for reading.
    Description, as the server wrote it
    Interior dimensions, volume, floor area and maximum payload for 47 shipping containers, truck trailers, rail wagons and air ULDs. Use this when someone asks for the internal or interior dimensions, cubic capacity, floor area, payload or weight limit of a container or trailer — 20ft, 40ft, 40ft High Cube, 45ft, reefer, open top, flat rack, 53ft dry van, curtainsider, boxcar, LD-3, PMC and more. Called with no arguments (optionally filtered by mode) it lists the whole catalog with the slug for each vessel.

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.
