WHY IT NEEDS A POLICY

Why wp_media_import needs a policy

The tool creates/writes new data (media files) to the WordPress database and filesystem. While it does not delete or overwrite existing media (which would be Destructive), and does not directly execute arbitrary code or trigger external side effects dependent on malicious arguments (which would be Execute), it does irreversibly add data.

From the tool's definition Tool is named 'wp_media_import' with description 'Import media from URL' — this creates new media assets in WordPress by fetching and storing content from an external source.
