WHY IT NEEDS A POLICY

Why create_staged_upload needs a policy

This tool enables file uploads and bulk data imports to the Shopify store, which modifies store state by introducing new data. While uploads themselves are Write operations (reversible via deletion), the 'bulk import data' capability could introduce significant amounts of data. However, without evidence of automatic execution or irreversible deletion, this is Write rather than Execute or Destructive.

From the tool's definition Tool creates staged upload targets for file uploads, including 'bulk import data before processing.' The act of creating upload targets and uploading files constitutes data creation/modification.
