Spur is an image generation system for Claude. Paste it into claude.ai and type “install Spur.” Claude becomes an image studio with over 200 tools.
Spur installs a graphics toolchain into Claude's environment. Describe what you want. The model browses its library, picks the right tool for the job, and writes the code that produces the image. There is no image model in the loop. Just code and math.
The model already knows how to use POV-Ray, Cairo, matplotlib, OpenSCAD, and the rest. Spur tells it which one to reach for, when, and how to combine them. The result is reproducible: every image is a script that can be run again.
