NiceEval 里怎么驱动 agent：send、session 与 HITL

const turn = await t.send("布鲁克林今天天气怎么样?");

turn.message;   // 最后一条 assistant 消息
turn.data;      // 结构化产物:仅当这次 send 声明了 output 时存在,类型随声明(见下)
turn.status;    // "completed" | "failed" | "waiting"
turn.events;    // 这一轮的 StreamEvent[]
turn.usage;     // { inputTokens, outputTokens, ... },adapter 报了才有
turn.succeeded(); // 作用域断言:这一轮没失败、也没卡在未回答的 HITL 上

const turn = await t.send("这张发票总额多少?", {
  output: z.object({ amount: z.number(), currency: z.string() }),
});
t.check(turn.data.amount, equals(3200));   // turn.data 是 { amount: number; currency: string }

const turn = await t.sendFile("fixtures/invoice.png", "这张发票的总额是多少?");
t.check(turn.message, includes("$"));

const draft = await t.send("帮我拟一封跟进邮件。");
draft.succeeded();
t.check(draft.message, includes("此致"));
draft.judge.autoevals.closedQA("语气是否专业").atLeast(0.6);

await t.send("好,发出去。");
t.calledTool("send_email");

await t.send("我叫小明。");
await t.send("我叫什么?");
t.check(t.reply, includes("小明"));         // 主 session 记住了

const fresh = t.newSession();
await fresh.send("我叫什么?");
t.check(fresh.reply, satisfies((r) => !r.includes("小明"), "没有记忆泄漏"));

const draft = await t.send("拟一封跟进邮件,但先别发,等我确认。");
draft.parked();                              // t.parked() 断言 status === "waiting"

const request = t.requireInputRequest({
  prompt: /是否发送/,
  optionIds: ["approve", "reject"],
});

await t.respond({ request, optionId: "approve" });
t.calledTool("send_email");

await t.send("把这批改动逐项提交审批。");
t.requireInputRequest({ display: /审批/ });

await t.respondAll("approve");
t.succeeded();
