name cad-skill description Generate interior design planning artifacts, 2D SVG floorplans, BOM outputs, analysis boards, and renovation image sets from structured requirements. Use for staged interior-design work that moves through plan, 2D drafting, BOM, and image outputs. CAD Skill Trigger Use when the task requires one step in an interior-design workflow. First-Use Reminder On the first use of this skill in a conversation, remind the user that image generation reads config/image-provider.json , and that it must be filled in before any image can be produced. Order Confirm the task is an interior-design task. Route the task to one step only: plan , 2d_svg , bom , or images . Collect missing required context for that step. Read the required references. Produce the step artifact. Export preview artifacts when requested. Bundle artifacts when requested.

Prefer plan when no usable plan exists. Use 2d_svg for drawing, redrawing, and localized floorplan edits. Use bom only when a plan exists. Use images only when the task is to produce analysis boards, drawing boards, or render images. Plan Contract Output one cad_plan artifact only. Keep assumptions explicit. Keep room names, functional needs, and constraints executable. Do not output SVG, BOM, or image tasks in the same step. 2D SVG Contract Output one cad_patch artifact or one full SVG result. Use patch for small precise edits. Use replace for broad redraws or unstable patch cases. Keep output limited to the 2D floorplan step. Export a local preview image when requested. BOM Contract Output one cad_bom.csv artifact only. Base BOM on the current plan and 2D SVG. Keep columns normalized and machine-readable. Images Contract Use prompts/overall-analysis-board.md to generate the text-model prompt for the overall analysis board. Use prompts/key-strategy-board.md to generate the text-model prompt for the key strategy board. Use prompts/master-renovation-scheme.md first to generate the text-model prompt for the master renovation scheme, then lock that JSON as the source of truth. After the master scheme, use one dedicated prompt file per sheet to generate seven different text-model prompts: prompts/renovation-plan-layout.md prompts/floor-finish-plan.md prompts/reflected-ceiling-plan.md prompts/wall-setting-out-plan.md prompts/mep-plan.md prompts/elevation-index-and-interior-elevations.md prompts/detail-drawings.md Do not reuse one prompt for all seven outputs. For every analysis board or sheet, first produce a dedicated image prompt with the host model, then pass that image prompt to the configured image model. Require config/image-provider.json before image generation. Do not ask the user to paste API keys into chat. Stop and tell the user to fill config/image-provider.json when apiKey or model is missing.
