Human approval matters because AI agents can misunderstand instructions, use tools incorrectly, or act on bad information. A review step lets a person catch mistakes before they become actions.
In practice
Approval is especially important for sending messages, publishing content, modifying production systems, deleting data, making purchases, changing permissions, or contacting customers.
What to watch
Approvals should show what the agent plans to do and why. A vague "approve" button is weak protection if the human cannot inspect the proposed action.
