Human-in-the-Loop Approval

Human-in-the-loop approval inserts a manual confirmation checkpoint before an agent executes a high-impact or irreversible tool call, such as sending money or deleting records. The agent proposes the action and its arguments, and a person reviews and authorizes it before execution proceeds. This gate catches misinterpretations and manipulation, trading some autonomy for safety on consequential side-effecting operations.
