WHY IT NEEDS A POLICY

Why generate_from_template needs a policy

This tool creates and produces new design screens/UI artifacts based on templates and user input. While it generates code-like outputs (UI designs), the effect is reversible (generated screens can be modified, deleted, or regenerated). It does not execute arbitrary commands, delete data, or perform financial operations.

From the tool's definition Tool description states it 'Generates a screen from a predefined UI template with user customizations' - this creates new UI/design artifacts. The verb 'generates' combined with 'from a template' indicates creation of new design outputs.
