WHY IT NEEDS A POLICY

Why scale_mesh_to_fit needs a policy

Based on the name alone, this tool likely scales/resizes a 3D mesh object to fit within certain dimensions, which is a reversible modification (Write). It operates on mesh geometry data in a 3D printing context. Confidence is low due to the empty description; it could be Execute if it triggers a printer action, but Write is the most reasonable inference from the name.

From the tool's definition Tool name 'scale_mesh_to_fit' — description is empty and uninformative.
