Delete subject data unless blocked by an active legal hold.
AI agents call delete_privacy_subject to permanently remove resources in ComplyOS — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes personal data records. Even though deletion can be blocked by legal holds, the primary function is destructive data removal that cannot be undone. In a compliance context, misuse by an AI agent could result in unauthorized deletion of regulated personal information, violating data protection obligations and creating potential legal/regulatory liability.
From the tool's definition Tool name is 'delete_privacy_subject' and description explicitly states it 'Delete[s] subject data unless blocked by an active legal hold.' The verb 'delete' combined with 'subject data' indicates irreversible removal of personal information.
