kilkellym/ArchSmarterFamFab ? reverse-engineered prompt

Build me a Revit add in that lets me turn a photo or sketch of furniture, lighting, or other building parts into a parametric family.

I want a simple workflow inside Revit, where I open a family template, click a FamFab button, choose an image, and have it send that image to Claude using my own Anthropic API key. Then it should show me a 3D preview of the generated family, let me tweak a few parameters, and only when I click generate should it create the actual geometry, parameters, reference planes, and subcategories in the Family Editor.

It should also let me load a JSON family definition directly instead of calling the API, and save my settings locally. Please make it work as a Revit add in with a clean settings window and preview window, and keep the prompt or schema easy to edit in the source if I want to improve it later. If you need current docs for Revit or WebView2, look them up online.
