Run your first streamed request

Use the agent and context created in the previous step:

const stream = agent.stream(
  {
    sessionId: "reference-session-001",
    message: "Explain the highest-risk parts of this project.",
  },
  context,
);
 
for await (const event of stream) {
  console.log(event.type, event.payload);
}
 
const terminal = await stream.result;
console.log(terminal.type);

Iteration reads live events for this request. stream.result resolves to the terminal event for that same run. Live progress does not replace the terminal result.

Cancel when the caller leaves

Pass an AbortSignal when the stream belongs to a request that may disconnect:

const stream = agent.stream(
  {
    sessionId: "reference-session-001",
    message: "Review the deployment configuration.",
    signal: abortController.signal,
  },
  context,
);

Aborting cancels that upstream run. The terminal promise resolves with run.cancelled, which should remain visible as a deliberate outcome rather than being converted into a generic network error.

Use a durable background subscription when observation must continue after the original request ends.
