| pack_boxes | Calculate how many identical boxes fit in a rectangular space, and where. The space is a shipping container, a pallet area, leftover container space, or a larger box. Give the box's L/W/H and EITHER a `container` preset OR the space's L/W/H (all in millimetres - container presets are mm). Boxes mix orientations across regions to pack densely; the plain maximum-load answer uses the exact SmartPacker T solver. Args: box_length: Box length. box_width: Box width. box_height: Box height. container: Container preset instead of explicit space dims (fills the internal usable L/W/H in mm; overrides space_* when recognised). ISO dry: 20GP 20HQ 40GP 40HQ 45GP 45HQ; NA domestic: 53HC 48HC; reefers: 20RF 40RF 40RH; EU pallet-wide: 40HQ-PW 45HQ-PW. Many aliases (20/40/45, 20ft, 40HC, 40', 40 reefer, ...). space_length: Space length (front-back). Use this OR `container`. space_width: Space width (left-right). space_height: Space height (up). count: How many boxes to load. 0 (default) loads the maximum. to_front: Anchor a partial load to the front (else the back). to_left: Anchor a partial load to the left (else the right). to_bottom: Kept for compatibility, no effect: boxes always rest on the floor. box_weight: Weight of one box (optional; same unit as max_weight). max_weight: Max total load weight (optional; 0 = no weight limit). include_image: Set true ONLY when the user wants to SEE or visualize the loading plan / 3D layout (e.g. "show the loading plan", "visualize it", "what does it look like?"). Default false is faster and lighter and still returns `image_url`, a shareable link to the 3D render. When true, the image is ALSO embedded inline (Claude Desktop and Cherry Studio display it; the claude.ai web app shows only the link either way). Returns the maximum that fits, how many were loaded, the fill rate, the region/block decomposition (each block's position, orientation, and grid), any weight limit applied, an `image_url` link to the rendered 3D loading plan, and - when include_image is true - the inline image too. | Read-only |
| send_feedback | Send a question, suggestion, or bug report about this container-loading tool to the Zhihuo maintainers. Use this when the user wants to ask the tool's authors a question, suggest an improvement (e.g. another container type or output field), or report a result that looks wrong. The note reaches the Zhihuo team. Args: message: The question, suggestion, or bug report, in plain text. contact: Optional email or handle if the user would like a reply. category: Optional tag - "question", "suggestion", "bug", or "other". Returns a short confirmation string. | Changes data |
