Tool items
The behavior pack defines 50 items, all plain items that stack to 1. They include the Building Assistant Kit, measure, circle and mound items, paste controls, history items and X, Y and Z position steps.
- Measuring: the author says it gives distance, dimensions and volume.
- Shapes: the changelog lists sphere, circle and torus generation, with customisable materials and placement modes.
- Structures: copy and save with 10 library slots, plus rotation, position adjustment, a placement preview, renaming, overwriting and deletion.

Files and languages
The behavior pack runs 13 JavaScript files from scripts/main.js. The resource pack has 15 texture files in textures/items, 1 entity texture, 1 model file and 1 client entity definition. Two languages are included: en_US and ja_JP.
- 1 custom entity is defined.
- No vanilla entity or item files are replaced.
Requirements and compatibility
- The manifest's minimum Minecraft version is 1.26.30 for both packs. That is the lowest version declared, not a promise for every later release.
- Both the behavior pack and the resource pack must be active in the world. The author's post says both are required.
- Experimental toggles: the script modules @minecraft/server 2.8.0 and @minecraft/server-ui 2.1.0 are stable versions, so the files do not point to Beta APIs.
- The author says some operations need the target chunks to be loaded.
- File size: 147.02 KB as one .mcaddon, 94 files inside.
