Share Sweep
Find the files shared outside your organisation: paste a Drive sharing export (CSV, GAM file list or Drive API JSON) and your own domain, and the page finds public files, anyone-with-the-link shares, outside editors and personal mailboxes, and maps where it all goes, all free. A metered run plans what to revoke, what to make view-only, what to keep and what to ask the owner. Built on the SkillSafe skill @googleworkspace/recipe-audit-external-sharing.
gpt-terra Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
