WHY IT NEEDS A POLICY

Why download_sketchfab_model needs a policy

This tool downloads an external asset and imports it into the Blender scene, which is a write/modification operation — it adds new data to the scene. It does not execute arbitrary code, delete data, or involve financial transactions. The blast radius is medium since it can introduce arbitrary external content into the working environment.
