Home interior design delivered as an interactive house designer page (one offline HTML, 2D / 3D / furniture / MEP / ceilings / quote / drawing set). From an existing floor plan (image, PDF, DXF, CAD) it reconstructs the plan in the designer. From a brief with no plan, the model first settles a design plan with the user (rooms, finishes, equipment, smart home, wiring preferences as clickable decisions), describes the layout as a grid with intent, and programs draw it; then the designer lays out…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CAD Skill Everything the user ends up with is the house designer in `designer/`: its page, its checks, its exports. Two routes lead there: reconstructing an existing floor plan, or designing from a brief. Both routes edit the same thing in the end: the designer's HouseSpec (`designer/reference/spec-format.md`; read it before editing a spec). On route A the reconstruction scripts and the GUIDE's generator scripts write it; on route B the layout program writes the first one, and from then on anything spec-format describes can be changed in the spec itself (below). Both routes have the same delivery gates: the designer's check at **0 errors and 0 warnings**, the MEP audit without ✗, and the designer's qa passed; whatever truly cannot be fixed (the original drawing is like that) is explained item by item. ## Pick the route | The user has | Route | |---|---| | An existing floor plan: image, screenshot, scan, CAD PDF, DXF, black CAD screenshot, two plans (original + layout) | **A — reconstruct.** Read `designer/GUIDE.md` and follow it from section 0 to 6 (its paths are relative to `designer/`). | …

How to install
mdr add codingfeng101/canvasanvil/cad-skill@sha256:59aa1df560dcf44eThe line at the top of this page pins the label git:20261108.7975556, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
