关键证据: "When we had our first retreat in Utah early this year, nobody had heard of Harness Engineering. This time we had a whole session on it." 与会者分享了具体实践——限制 context 大小、使用 Rust 替代 Python、形式化方法验证。
核心结论2: Agent 的"工作单元"是当前核心争议——所有 session 都在回答同一个问题："How much do we let an agent decide, and how do we stay confident in what it does?" 不同团队在设置同一组控制参数：工作单元大小、交接准备、返回值检查、Agent 边界约束。
关键证据: Kief Morris 的跨 session 综合发现——"people were making the same handful of choices over and over about a single thing: the unit of work they were prepared to hand to an agent."
关键证据: Sam Ruby 的"Bring Me a Rock"session——"When a manager reaches for an LLM instead of routing the work to the team, they didn't pick up a tool — they made a hire." 非工程师使用 LLM 的风险不是权限问题，而是 manage by method 而非 by objective 的旧病。
