WHAT IT DOES

What create_legal_hold does on ComplyOS

AI agents use create_legal_hold to create or update resources in ComplyOS — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ComplyOS environment.

WHY IT NEEDS A POLICY

Why create_legal_hold needs a policy

The tool creates a legal hold record (Write) that actively prevents data deletion. It does not itself delete data, but it enforces a preservation constraint that has significant legal and operational consequences. Misuse could wrongly freeze data deletion for individuals or organizational records, creating compliance and legal exposure — hence high severity.
