Composition
Place the approval surface inside the message that pauses the agent run.
Message
└── MessageContent
└── ApprovalCardNote: Tool Approval handles the narrower case of one tool permission. Message places the decision inside the conversation history. Todo List shows which planned work is paused by the decision.
How it works
Human-in-the-loop work is a temporary transfer of control. The card should state the decision clearly, collect only the required input, and return a durable answer to the paused agent run.
