WHY IT NEEDS A POLICY

Why export_to_images needs a policy

This tool creates new files (image exports) on disk, which classifies it as Write rather than Read (which would only query/retrieve data without creating artifacts). It is not Destructive because the export does not delete or overwrite existing presentation files. While file I/O occurs, it is not arbitrary code execution (Execute category), and there is no financial impact.

From the tool's definition Exports all slides as individual image files to a directory, creating new files on the filesystem. The action is reversible (exported images can be deleted), and no existing data is modified or destroyed.
