WHY IT NEEDS A POLICY

Why sprout_upload_media needs a policy

This tool creates new data (media files) in Sprout Social in a reversible manner. It does not execute arbitrary code, destroy data, or move money. The severity is medium because uploading media could enable spam, malicious content distribution, or brand impersonation if misused by an agent, but the action itself is reversible (media can be deleted).

From the tool's definition Tool description states 'Upload media to Sprout Social' and 'Returns a media_id for use in post creation', indicating it creates/stores new media assets in the system.
