<UseCaseHero title="将生产环境热修复转化为操作手册" description="从一次成功的故障响应会话中抽取精确步骤，让团队每次都能复现修复过程。" prompt="上周二的内存泄漏故障处置会话堪称教科书级——Devin 找到了连接池中的泄漏点，应用修复，在预发布环境验证后实现零停机部署：[session link]。从中提取一份可复用的热修复操作手册，让值班工程师在后续内存问题中都能按同样流程处理。" category="Devin 优化" features="高级, 操作手册" agent="advanced" intent="create" />

<div className="uc-detail-wrapper">
  <Tip>不想手动设置？把此页面的链接粘贴到 Devin 会话中，并让它为你完成全部设置。</Tip>

  <Steps>
    <Step title="识别值得沉淀为操作手册的故障会话">
      在解决一次生产故障后，你会得到一份 Devin 会话记录，里面完整记录了每一步诊断操作、执行的每条命令，以及在压力下做出的每个决策。这份记录就是为值班团队制作可复用操作手册的原材料，下次可以直接套用。

      不是每次故障会话都适合写成操作手册。重点关注 Devin 遵循了清晰、可重复方法论的会话——也就是你们团队经常遇到的那类故障：

      * **内存泄漏**——识别泄漏源头、应用修复、在发布后验证堆内存使用情况是否恢复正常
      * **连接池耗尽**——追踪根因、调优连接池参数、补充监控
      * **级联超时**——隔离故障上游、添加熔断器、验证恢复效果
    </Step>

    <Step title="创建操作手册">
      打开 [Devin 主页](https://app.devin.ai/?utm_source=docs\&utm_medium=use-case-gallery) 并启动一个新会话。描述你想要转化为操作手册的会话。

      粘贴故障会话链接，并描述操作手册应该覆盖的内容。要把**泛化范围**说清楚——操作手册应该适用于这一类故障，而不只是当前这个出问题的服务。

      <PromptBlock agent="advanced" intent="create">
        ```txt Create hotfix playbook from incident session theme={null}
        This session diagnosed and fixed a memory leak in our payments service
        caused by unclosed database connections:
        https://app.devin.ai/sessions/abc123

        Create a reusable hotfix playbook for memory-leak incidents that any
        on-call engineer can attach to a new session. It should:
        - Generalize the diagnostic steps (not payments-specific)
        - Include the heap profiling approach from the session
        - Capture how it validated the fix in staging before deploying
        - Keep the rollback procedure in case the fix makes things worse
        - Add a step for posting a summary to the #incidents Slack channel
        ```
      </PromptBlock>

      如果你有多次相同类型的已解决故障 (例如两次不同的内存泄漏会话) ，可以把它们都加进去。Devin 会识别跨会话的共性模式，生成更加健壮的[操作手册](/zh/product-guides/creating-playbooks)。
    </Step>

    <Step title="在下一次故障中验证效果">
      真正的检验标准，是这个操作手册能否在*不同*但同一类别的故障中奏效。当下一次内存问题出现时，新建一个 Devin 会话，附加这个操作手册，并指向受影响的服务。

      <PromptBlock>
        ```txt Diagnose memory leak in the notifications service theme={null}
        Use the attached hotfix playbook to investigate and fix a memory leak
        in the notifications service. OOM kills started at 03:12 UTC.
        The service is at src/services/notifications/.
        ```
      </PromptBlock>

      如果会话能够顺利解决故障，说明你的操作手册泛化得很好。如果遇到困难——比如泄漏模式不同，或者服务使用了不同的数据库驱动——就把这次会话重新交给 Devin，并让它改进这份操作手册。关于该工作流，可以参考[修复不稳定的数据库迁移操作手册](/zh/use-cases/gallery/improve-playbook-from-sessions)。
