<hr>
<h2 id="专业系统的流动性监控框架">专业系统的流动性监控框架</h2>
<p>这套框架涵盖15个指标，覆盖资金需求、资金供给、货币价格三个维度，从IPO抽血到北上资金、从SHIBOR到产业资本增减持，每周更新，每个指标给出A到E的评级，最终加权得出&quot;股市流动性综合评级&quot;。</p>
<p>从2018年3月的C级，到2018年8月的B级，再到2019年2月的B级——每一次评级背后都有清晰的逻辑支撑。3月是因为货币偏紧、产业资本持续减持；8月是因为央行开始降准、北上资金逆势流入；2019年初则叠加了社融超预期放量的信号。</p>
<p>这套体系的完整性和自洽性，放在今天依然值得学习。</p>

<hr>
<h2 id="这些数据当时真的帮到人了吗">这些数据，当时真的帮到人了吗？</h2>
<p>如果我们开着倒视镜回看当时的报告以及当时的市场，会发现。</p>
<p>2018年是A股当时调整的起点，2018年初市场延续2017年蓝筹行情冲高，在春节特朗普签署对华301调查备忘录，引起中美贸易战的恐慌，A股应声大跌。当时的流动性报告评价长期是C，而2018年8月，报告给出B级评级，当时北上资金持续流入，货币政策转松，各项指标改善明显。但上证指数从那时起继续跌了将近半年，一直跌到2019年1月才见底。如果你在8月看到B级评级就认为&quot;流动性改善，可以加仓&quot;，那接下来几个月的体验并不会太好。</p>
<p>这不是在批评报告本身——报告从未声称自己是择时工具。但问题是，<strong>大多数读报告的人，心里期待的恰恰是某种择时信号。</strong> 这是报告的功能与读者期待之间的结构性错位。</p>
<hr>
<h2 id="资金面数据的本质一面记录过去的镜子">资金面数据的本质：一面记录过去的镜子</h2>
<p>回头想想，这件事其实并不奇怪。</p>
<p>成交量、换手率、融资买入额——这些数据记录的是市场参与者<strong>已经完成的行为</strong>。北上资金本周净流入多少亿，说明的是外资上周买了什么，而不是下周会买什么。基金发行量高，说明的是现在情绪乐观，而乐观情绪恰恰是在市场已经涨了一段时间之后才产生的。</p>
<p>换句话说，资金面数据天生是同步的，在很多情况下甚至是滞后的。<strong>用它来预判方向，是对它能力边界的误读。</strong></p>
<hr>
<h2 id="那么它在哪里真的有用">那么，它在哪里真的有用？</h2>
<p>经过这番翻看和反思，我认为资金面数据的价值主要体现在两个地方。</p>
<p><strong>第一，判断当前所处的宏观流动性环境。</strong> DR007、SHIBOR、国债收益率的水位，决定了整个市场的定价环境。资金便宜的时候，市场可以容忍更高的估值；资金昂贵的时候，高估值股票的压力会系统性增大。这不是择时，是理解市场背景的基础底层，需要长期跟踪，而不是单周数据的涨跌。</p>
<p><strong>第二，识别情绪的极端状态。</strong> 这是我认为资金面数据最有价值的地方，但它指向的不是&quot;方向预判&quot;，而是&quot;风险感知&quot;。</p>
<p>当融资余额占流通市值的比例跌破某个历史低位，当新基金发行几乎停滞，当成交量萎缩至冰点，当产业资本开始大规模净增持——这些信号叠加在一起，说明的不是&quot;明天会涨&quot;，而是&quot;市场已经把悲观情绪定价得相当充分了&quot;。反过来，当爆款基金频出、融资盘快速攀升、大宗交易折价率消失——这不是涨势结束的精确时点，但它提示你应该开始认真审视自己的持仓风险。</p>
<p><strong>极值是提醒你调整心态的信号，而不是给你确定性答案的信号。</strong></p>
<hr>
<h2 id="我们真正需要的可能比我们想象的少">我们真正需要的，可能比我们想象的少</h2>
<p>八年前，一份合格的资金面研报需要追踪15个指标、每周更新数十张图表。今天，信息的获取成本更低了，数据的种类更多了，但投资者面对数据时的困惑，似乎并没有减少。</p>
<p>这让我觉得，问题可能不在于数据的数量，而在于我们与数据的关系。</p>
<p>我们总是希望数据能告诉我们该怎么做。但数据能做到的，其实只是帮助我们更清楚地看到当下的状态。把&quot;看清状态&quot;当成&quot;预判未来&quot;，是投资者面对数据时最常见、也最昂贵的一种误解。</p>
<p>真正有用的资金面框架，大概只需要三件事：持续感知货币环境的松紧，定期观察情绪指标是否走向极端，以及在极端信号出现时，保持足够的耐心等待基本面或政策面的共鸣。</p>
<p>剩下的那些图表，不看也罢。</p>

<h2 id="一进入项目四层目录各司其职">一、进入项目：四层目录，各司其职</h2>
<p>Anthropic 在 GitHub 上发布了一个叫 financial-services 的项目，随后出现了不少介绍它的文章，标题大多是&quot;Anthropic 开源了金融 AI Agent&quot;&ldquo;10 个金融角色全覆盖&quot;之类。但仔细看那些介绍，大多数停在截图和目录层面——这个项目有哪些文件夹，大概能做什么，就到此为止了。</p>
<p>这篇文章想做两件更具体的事：一是搞清楚这个项目<strong>里面到底有什么、怎么用</strong>；二是从它的文件里提炼出<strong>可以直接借鉴的方法</strong>——如果你有自己的专业工作流，怎么把它固化成像这个项目一样的 Skill 文件。</p>
<p>先把项目结构说清楚。整个 repo 有四个顶层目录：</p>

<p>根目录下的 <code>.claude-plugin/marketplace.json</code> 是整个 repo 的&quot;目录页&rdquo;，把所有可独立安装的插件（20 个）列在一起，作为一个 marketplace 源发布。</p>
<p><strong>这几部分之间是什么关系？</strong></p>
<p><code>vertical-plugins</code> 是技能的&quot;原料库&quot;。每个 vertical 收录了一个金融子领域的技能文件（Skill）和用户可手动触发的斜杠命令（如 <code>/dcf</code>、<code>/comps</code>）。连接外部数据平台的 MCP 配置并不分散在各个 vertical，而是统一集中在 <code>financial-analysis</code> core plugin 里，其余 vertical 共享这一份连接器配置。如果你只是想在 Claude 里执行 <code>/dcf</code> 这样的命令，装对应的 vertical 就够了。</p>
<p><img alt="vertical-plugins-overview-bilingual" loading="lazy" src="/posts/anthropic-financial-services/1.vertical-plugins-overview-bilingual.png"></p>
<p><img alt="1.vertical-plugins-skill-map-bilingual" loading="lazy" src="1.vertical-plugins-skill-map-bilingual.png"></p>
<p><code>agent-plugins</code> 是把这些原料拼装好的&quot;成品&quot;。每个插件针对一个完整工作流（比如建模、月末结账、KYC 审查），把它需要用的技能从 vertical 里复制一份打包进来，安装后不需要额外依赖。两者的关系是：vertical 是积木，agent-plugin 是用积木拼好的成品，两者可以独立安装，也可以一起用。</p>
<p><img alt="2.agent-plugins-skill-matrix-bilingual" loading="lazy" src="/posts/anthropic-financial-services/2.agent-plugins-skill-matrix-bilingual.png"></p>
<p><code>partner-built/</code> 是第三方数据平台方独立开发并贡献的插件，目前收录两个：LSEG 和 S&amp;P Global 各一套。它们在结构上与 <code>agent-plugins</code> 一致，可以通过插件市场正常安装，但由各自的平台方负责维护。这两个插件将各自平台的数据查询能力——市场行情、公司基本面、行业研究——以 Skill 文件的形式封装进来，让 Claude 可以直接调用平台数据，而不需要用户手动切换到对应的数据终端。使用这类插件通常需要持有对应平台的订阅授权。</p>
<p><img alt="partner-built-plugins-skill-map-bilingual" loading="lazy" src="/posts/anthropic-financial-services/3.partner-built-plugins-skill-map-bilingual.png"></p>
<p><code>managed-agent-cookbooks</code> 和 <code>agent-plugins</code> 对应同一批工作流，两者实际上引用的是同一套目录和文件——相同的系统提示与 Skill 文件，Cowork 和 Managed Agent wrapper 都指向同一个 <code>agent-plugins/&lt;slug&gt;/</code>。区别在于部署方式：Cowork 用插件市场安装；Managed Agents API 则由开发者通过 <code>deploy-managed-agent.sh</code> 脚本自行部署到自己的系统里。cookbook 里在这套共享文件基础上额外补充了无头部署所需的内容：子工作者分工定义（<code>agent.yaml</code>）和引导示例（steering-event examples）。</p>
<p><img alt="managed-agent-cookbooks-pattern-bilingual" loading="lazy" src="/posts/anthropic-financial-services/4.managed-agent-cookbooks-pattern-bilingual.png"></p>
<p><code>claude-for-msft-365-install</code> 和上面几部分没有功能关联。它不是一个 AI 工作流，而是给 IT 管理员用的安装向导——把 Claude 的 Microsoft 365 插件部署到企业租户里，处理 Azure 权限配置、生成 manifest 等步骤。它是一个 Claude Code 插件，不是 Cowork 插件。</p>
<p><code>scripts/</code> 是维护工具，包含五个脚本：<code>sync-agent-skills.py</code> 负责把 vertical 里修改过的技能同步到打包了它的 agent-plugin；<code>check.py</code> 在推代码前做 lint、交叉引用校验，以及检测 agent-plugin 里打包的技能是否已与 vertical 源文件产生偏差（drift）；<code>deploy-managed-agent.sh</code> 负责把指定工作流部署到 Managed Agents API；<code>orchestrate.py</code> 是路由 <code>handoff_request</code> 事件的参考事件循环实现；<code>validate.py</code> 负责额外的校验工作。</p>

<h2 id="二plugin-体系三种-skill-编排原型">二、Plugin 体系：三种 Skill 编排原型</h2>
<p>Plugin 是 Anthropic 推出的一种即插即用打包格式，将完整的 Skill、MCP 配置、Hooks 和 Subagents 捆绑在一起发布——工作流所需的全部配置，作为一个独立单元安装或卸载，不需要逐项手动配置。</p>
<p>Agent-plugins 与 Vertical-plugins 内容高度重叠，但 Agent-plugins 以角色为起点，结构更容易理解。以它为例精读，可以更清楚地看到 Anthropic 如何设计 Plugin 体系。</p>
<p><code>agent-plugins</code> 层有 10 个角色，每个角色持有若干 Skill，但 Skill 之间的编排方式差异很大。精读这些 Agent 文件后，可以归纳出三种原型。</p>

<p>代表：<code>model-builder</code></p>
<p>这个 Agent 的系统提示非常简洁，核心是这段：</p>

<p>这个 Agent 是一个<strong>调度器</strong>。用户说&quot;帮我做一个 AAPL 的 DCF&quot;，Agent 判断这是 DCF 请求，调用 <code>dcf-model</code> Skill；用户说&quot;做一个 Comps&quot;，Agent 调用 <code>comps-analysis</code> Skill。每个 Skill 是一个独立的专家，Agent 本身不执行金融分析，只做路由和编排。</p>
<p>这种模式适合的场景是：用户的请求类型是可枚举的，每种类型对应一套相对固定的处理流程。</p>

<p>这是严格的<strong>流水线</strong>。上一个步骤的输出，是下一个步骤的输入。技能之间的关系不是&quot;选择哪个&quot;，而是&quot;必须按顺序全部执行&quot;。</p>
<p>值得注意的是，这个 Agent 明确声明：<strong>No GL posting</strong>（不进行总账过账）。所有的技能只起草日记账分录，不实际写入 GL 系统。&ldquo;诊断不执行&quot;是一种通过架构设计的安全边界，而不是依靠 Agent 自我约束。</p>

<p>各个估值技能之间没有依赖关系——DCF 不需要等 Comps 跑完，LBO 不依赖 3-statement 的输出。它们各自完成自己的分析，最后 <code>pitch-deck</code> 技能把所有结果组装成一份完整的投行 pitch 材料。</p>
<p><code>market-researcher</code> 的结构完全一样：<code>sector-overview</code>、<code>competitive-analysis</code>、<code>comps-analysis</code>、<code>idea-generation</code> 分别覆盖行业概述、竞争格局、估值可比、投资标的四个维度，最后由 note-writer 整合成一份研究报告。</p>
<p>这和管道型的核心区别是：管道型里每一步必须等上一步的输出才能开始；多视角组装型里各分析技能平行运转，彼此不传递中间结果，只在最后一步汇总。</p>
<p>这种模式还有一个共同特征：工作流在<strong>两个节点</strong>明确停下来等人审批。<code>pitch-agent</code> 的系统提示写明：Excel 模型建完停一次，deck 生成后再停一次。每份中间交付物都需要人确认后才继续推进。这和管道型&quot;一路跑到底再等签字&quot;不同，是有意把人嵌入在流程中间，而不是只在末尾。</p>

<p>从 Plugin 层往下走一层，深入具体的 Skill 文件，看 Anthropic 如何把真实的专业工作流编码为 AI 行为规范。</p>
<p><code>dcf-model</code> 是整个 financial-services 项目里设计密度最高的 Skill 文件：1263 行，包含完整的工作流、专门的&quot;正确做法&quot;章节、专门的&quot;错误做法&quot;章节、质量检查清单，以及强制运行的外部验证脚本。研究这个文件的价值，不在于它包含了多少金融知识，而在于它展示了一套<strong>把复杂领域工作流编码为 AI 行为规范的方法</strong>。</p>

<p>这是一个典型的<strong>模式选择</strong>设计：在任何实质性工作开始之前，先确定执行路径。两种环境的工具和约束截然不同——Office JS 环境不需要 <code>recalc.py</code>（Excel 原生计算），但禁用 openpyxl；独立文件模式则必须通过 <code>recalc.py</code> 进行公式验证。</p>
<p><strong>为什么要放在最前面</strong>：如果这个判断出现在工作流的中间，当 Agent 在第五步发现自己用错了工具，前五步的所有工作都需要重来。模式判断前置，是在确保路径错误不会在工作流深处才被发现。</p>
<p><code>comps-analysis</code> Skill 用了同样的逻辑，但针对的是分析情境而非技术环境。在开始任何分析之前，它要求先回答四个问题：</p>

<p>这四个答案决定了后续选哪些指标、如何组织输出。两个 Skill 遵循相同的设计原则：<strong>把判断逻辑前置到工作流入口，而不是让 Agent 在执行过程中动态切换路径</strong>。</p>
<h3 id="2-把工作流切成有定义输出的小块">2. 把工作流切成有定义输出的小块</h3>
<p>DCF 的工作流是 10 步，但它的独特之处不在于步骤数量，而在于步骤之间有<strong>明确的确认节点</strong>，且这些节点是 Critical Constraints 里的硬性要求：</p>

<p><strong>这五个节点不是平均分布的</strong>，每一个都位于依赖链的上游——若此处之后出现错误，需要重建大量下游计算。把确认节点放在这些位置，是在最小化错误传播的范围。</p>
<p>另一个设计细节是每个节点都有<strong>定义好的展示内容</strong>。不是&quot;向用户展示一些信息&rdquo;，而是&quot;展示原始输入模块（收入、利润率、股份数、净债务）&quot;——明确指定了要展示什么。Agent 在确认节点只需填充既定格式，不需要判断&quot;我应该展示什么&quot;。</p>
<p><strong>可迁移的原则</strong>：确认节点的位置应该根据错误传播成本来决定，而不是按时间平均分布；每个节点的输出应有明确的内容定义。</p>

<p>&ldquo;请立即停止&quot;这个措辞不常见。它是对一个具体行为倾向的干预：AI 没有约束时，倾向于在 Python 里算出结果，然后把数字直接写进单元格——这样做产生的是&quot;死&quot;模型，用户修改假设时静态数字不会更新。这条约束把一个隐性的专业要求（模型必须是&quot;活的&rdquo;）变成了一个<strong>带自我中断点的明确禁令</strong>。</p>

<p>这条约束的技术细节程度很高：具体的 API 调用顺序、具体的错误消息文本（<code>InvalidArgument: The number of rows or columns in the input array doesn't match</code>）。这种细节不会凭空出现在文档里。背后大概率是：Agent 在某次运行时触发了这个 bug，有人 debug 了问题，找到了正确写法，然后把正确和错误的例子都记录进了 Skill 文件。</p>
<p><strong>这是从 bug 经历到规范文档的转化过程</strong>。Skill 文件里类似细节度的约束，基本上都有这个来源。这也是理解&quot;为什么要有 Critical Constraints 章节&quot;的关键：它不只是预防性的设计，很大程度上是从实际运行中踩过的坑提炼出来的规范。</p>
<p><strong>约束三：recalc.py 强制验证</strong></p>

<p><code>recalc.py</code> 是一个用 LibreOffice 强制重算 Excel 公式、扫描所有错误单元格、输出 JSON 报告的外部脚本。它的存在基于一个对 AI 行为的工程认知：AI 会声称任务已完成，但实际上某些公式存在错误。这条约束不信任 AI 的自我报告，用外部机器验证来兜底——&ldquo;交付&quot;这个节点变成了可机械化验证的门槛：不是 Agent 说&quot;模型完成了&rdquo;，而是 <code>recalc.py</code> 返回 <code>&quot;status&quot;: &quot;success&quot;</code> 才算完成。</p>
<p><strong>三条约束背后的共同逻辑</strong>：每一条都针对 AI 在没有约束时的一个已知行为倾向——用静态数字（省事）、自报完成（乐观）、写嵌套 IF（直觉但不专业）。Critical Constraints 把这些已知失误模式从隐性风险变成了显性禁区。</p>

<p>两个章节的篇幅大致相当。这个结构有一个工程理由：AI 在没有约束时通常不会选择&quot;明显错误&quot;的路径，而是会选择**&ldquo;看起来没问题但实际上有缺陷&quot;的路径**——因为那条路通常更省事。</p>
<p>以情景逻辑的实现为例：</p>
<p><strong>AI 的自然倾向（Common Mistakes 记录的错误做法）</strong>：在每个公式里嵌套 IF</p>

<p>这个清单不是&quot;建议确认&quot;，而是交付的硬性门槛。</p>
<p>它的价值不只是防遗漏，而是把&quot;一份合格的投行 Excel 模型长什么样&quot;这个专业判断，结晶成了一个 Agent 可以逐条自检的可执行列表。这让&quot;合格&quot;从一个依赖经验的主观判断，变成了一个可以机械化验证的标准。</p>
<p>如果你为自己的工作流设计 Skill 文件，在文件末尾加一个&quot;交付前检查清单&quot;，可能是成本最低、收益最高的一个设计决策。</p>
<p>以下是按照 <code>dcf-model</code> Skill 生成的 Excel 截图，每个假设节点均保留在独立区域，所有计算单元格使用公式而非静态数值：</p>

<h2 id="四agent-工程的核心用权限定义边界">四、Agent 工程的核心：用权限定义边界</h2>
<h3 id="分工的方式决定了边界在哪里">分工的方式决定了边界在哪里</h3>
<p>多 Agent 系统里最常见的分工方式有两种：一是按任务阶段划分——一个 Agent 负责采集，一个负责分析，一个负责输出；二是按协调者与执行者划分——一个 Orchestrator 负责分解任务、指派工作，多个 Worker 各自执行，这是当前主流框架普遍采用的模式。两者都依赖系统提示来约束行为——告诉每个 Agent 它是什么角色、该做什么、不该做什么。</p>
<p>问题在于，指令是软的。模型幻觉、提示注入、边界情况下的判断失误，都可能让 Agent 越过文字边界。</p>
<p><code>managed-agent-cookbooks</code> 里的设计给出了一个不同的答案：<strong>用工具权限定义边界，而不只是用指令约束行为</strong>。分工的依据不再是&quot;这个 Agent 懂什么&quot;或&quot;它扮演什么角色&quot;，而是&quot;它被允许与外部世界发生什么样的交互&quot;。</p>
<h3 id="pitch-agent最直接的例子">pitch-agent：最直接的例子</h3>
<p><code>pitch-agent</code> 做的事情很好理解：给定一个目标公司，生成一份 pitch deck。它把工作分给三个子代理：</p>
<table>
  <thead>
      <tr>
          <th>子代理</th>
          <th>工具集</th>
          <th>职责</th>
      </tr>
  </thead>
  <tbody>
      <tr>
          <td><code>researcher</code></td>
          <td>Read + Grep + CapIQ/Daloopa MCP</td>
          <td>拉取可比公司和交易数据，返回结构化数据</td>
      </tr>
      <tr>
          <td><code>modeler</code></td>
          <td>Read + <strong>Bash</strong> + CapIQ/Daloopa MCP</td>
          <td>在 Python 沙盒里跑 DCF/LBO 计算</td>
      </tr>
      <tr>
          <td><code>deck-writer</code></td>
          <td>Read + <strong>Write</strong> + Edit</td>
          <td>把结果写成 .xlsx 和 .pptx 文件</td>
      </tr>
  </tbody>
</table>
<p>工具配置里有一行注释：</p>
<div class="highlight"><pre tabindex="0" class="chroma"><code class="language-yaml" data-lang="yaml"><span class="line"><span class="cl">- {<span class="w"> </span><span class="nt">manifest</span><span class="p">:</span><span class="w"> </span><span class="l">./subagents/deck-writer.yaml }  </span><span class="w"> </span><span class="c"># only leaf with Write</span><span class="w">
</span></span></span></code></pre></div><p><em>译：整个工作流里，唯此节点持有写入权限。</em></p>
<p>整个工作流里，只有 <code>deck-writer</code> 持有 <code>Write</code> 权限。<code>researcher</code> 能访问外部数据源，但写不了文件；<code>modeler</code> 能执行 Python 脚本做计算，但同样没有 Write——它把计算结果传给下一层，而不是自己写出最终文件。</p>
<p>不需要读懂系统提示，只看工具集，就能知道这个系统里哪个节点会产生持久的副作用。安全边界变成了可以直接检查的配置，而不是需要理解意图才能判断的文字。</p>
<h3 id="meeting-prep-agent当输入不可信时">meeting-prep-agent：当输入不可信时</h3>
<p><code>meeting-prep-agent</code> 处理的是更有现实风险的场景：它要读取客户邮件和外部新闻——这些都是不可控的外部输入。</p>
<p>它的 <code>news-reader</code> 子代理，系统提示开头是：</p>

<p>最后，唯一持有 Write 的 <code>pack-writer</code> 在系统提示里写了一句：</p>

<p><em>译：永远不要直接打开客户提供的文档。</em></p>
<p>它只接收经过前两个子代理清洗过的结构化数据，永远不直接碰外部原始输入。</p>
<p><strong>这套设计的逻辑是：让接触不可信内容的节点没有执行能力，让有执行能力的节点不接触不可信内容。</strong></p>
<h3 id="skill-文件和脚本固化知识的两种形式">Skill 文件和脚本：固化知识的两种形式</h3>
<p>这个项目还有一个值得单独说的地方：它清楚地区分了哪些东西应该写成 Skill 文件，哪些应该写成脚本。</p>
<p><code>scripts/</code> 文件夹里有两个最能体现这个判断的脚本：</p>
<ul>
<li><code>check.py</code>：推代码前跑，检查每个 manifest 格式是否合法、所有交叉引用是否能解析、agent-plugin 里打包的技能有没有和 vertical 源文件产生偏差（drift）。</li>
<li><code>recalc.py</code>：交付 Excel 模型前跑，用 LibreOffice 强制重算所有公式，扫描 <code>#REF!</code>、<code>#DIV/0!</code>、<code>#VALUE!</code> 等错误，要求零错误才算通过。</li>
</ul>
<p>这两类工作为什么写成脚本而不是 Skill 文件？因为它们的正确标准是完全确定的——引用要么能解析要么不能，公式要么有错要么没有，没有&quot;大致正确&quot;的空间。如果交给 AI 自我声明，AI 会告诉你&quot;没问题&quot;，但实际上可能有问题。脚本不会说谎。</p>
<p>反过来，Skill 文件（<code>dcf-model</code>、<code>comps-analysis</code> 这类）处理的是另一类问题：什么情况下用四分位而不是均值、DCF 敏感性分析应该覆盖哪些变量、Comps 的样本排除标准是什么——这些判断依赖上下文，需要根据具体情况调整，正是语言模型擅长的部分。</p>
<p>一个简单的判断标准：如果一个工作的结果可以被机械验证（通过/不通过），写成脚本；如果需要根据上下文做专业判断，写成 Skill 文件。这个项目里两者都有，各自用在了正确的地方。</p>
<hr>
<h2 id="五如果你也想为自己构建一套-agent-工作流">五、如果你也想为自己构建一套 Agent 工作流</h2>
<p>以下几条经验，来自对这个项目 Skill 文件的观察，适用范围不止于金融行业，也不止于技术人员。</p>
<p><strong>1. 用权限划边界，不用指令立规矩</strong></p>
<p>上一章已经展示了这一点：给 Agent 配什么工具，比告诉它&quot;不要做什么&quot;更可靠。指令是软的，工具集是硬的。</p>
<p><strong>2. 把工作流切成小步，每步设一个&quot;给我看看&quot;的节点</strong></p>
<p>不要让 Agent 一口气完成整个任务再给你看结果。在最关键的依赖节点——也就是&quot;这里出错，后面的工作都得重来&quot;的地方——设置确认环节，让 Agent 先展示中间成果，你确认没问题再继续。</p>
<p>这不是不信任 AI，而是把错误的传播范围控制在最小。一个发现得越早的错误，修正成本越低。</p>
<p><strong>3. 写下&quot;绝对不能做什么&quot;，比写&quot;应该做什么&quot;更重要</strong></p>
<p>大多数人在设计 Skill 时，只写了&quot;应该怎么做&quot;。但 AI 在没有约束时，倾向于选择&quot;看起来没问题但实际上有缺陷&quot;的路——因为那条路通常更省事，结果在表面上也说得过去，问题只有在仔细检查时才会暴露。</p>
<p>试着专门写一节&quot;禁止事项&quot;，记录 AI 在这个任务上最可能走错的那些弯路。这是一个容易被忽视、但回报很高的设计决策。</p>
<p><strong>4. 把踩过的坑写进 Skill，让它变成规范</strong></p>
<p>每次 Agent 出现了你没有预料到的问题，不要只在那次对话里纠正它——把那个坑写进 Skill 文件，变成一条明确的约束或示例。</p>
<p>Skill 文件应该随着使用而变厚。它不是一次性写完就不动的东西，而是你和 Agent 协作经验的积累。你踩过的坑越多、记录得越清楚，Skill 就越可靠。</p>
<p><strong>5. 定义&quot;完成&quot;的标准，不要只靠 AI 说&quot;我完成了&quot;</strong></p>
<p>AI 有一个已知的行为倾向：它会说任务完成了，但有时候并没有——可能某些细节遗漏了，可能某个步骤只是看起来做了。</p>
<p>在 Skill 里写一个&quot;交付前检查清单&quot;，把你认为&quot;合格的成果长什么样&quot;转化成可以逐条核查的标准。让&quot;完成&quot;变成一个可验证的状态，而不是一个主观判断。这个清单可能是整个 Skill 文件里成本最低、收益最高的部分。</p>
<hr>
<h2 id="结语">结语</h2>
<p>与 Agent 共事，不是把任务丢给它、等它出结果。这个项目里更重要的一层是：把你的工作经验、判断规则、踩过的坑，一条一条写进它的行为约束里。</p>
<p>这是&quot;让 AI 做金融工作&quot;和&quot;让 AI 做好金融工作&quot;之间的差距。也是&quot;使用 Agent&quot;和&quot;与 Agent 共生&quot;之间的差距。</p>
<p>Skill 文件的密度，是从业者经验的密度。</p>

<p>我喜欢看动物世界。</p>
<p>或许是因为，动物之间的协作与竞争，和人类社会如出一辙——却又剥去了一切修饰，还原成最原始、最野生的社会关系。</p>
<p>你会看到母亲与孩子之间本能的依恋，看到不同物种之间出人意料的温馨友谊。偶尔也会看到一些动物科普，让我觉得这个世界比我以为的要有趣得多。</p>
<p>在某个你从未去过的地方，生活着你从未见过的物种，它们有着你想不到的自然习性。一切是那么的自然而然，那么的恰到好处。</p>
<hr>
<p>前段时间，我看过一段让我屏息的视频：沙漠里，一只母猫与毒蛇之间的搏斗。</p>
<p>毒蛇趁母猫外出，攻击了它的幼崽。母猫归来，誓死护住剩余的孩子，与蛇正面交锋。</p>
<p>它凭借充满智慧的策略与蛇进行僵持，用比蛇更敏捷的反应一点点占据优势，消耗蛇的体能。等蛇的动作开始迟钝，它抓住时机，一击毙命。</p>
<p>整个过程不过两三分钟，我暗自为母猫鼓劲，希望它为它的孩子实现复仇。</p>
<p>正当我准备点赞，却看到下面这一行小字：</p>
<p><strong>疑似使用 AI 生成。</strong></p>
<hr>
<p>今天，又是一段视频。</p>
<p>主角是走鹃——一种因为走得太快、翅膀近乎退化的鸟。视频里，它吃饱了没事干，主动去招惹郊狼玩耍。</p>
<p>说是玩耍，其实是勾引郊狼去抓他。</p>
<p>它用极快的步频、灵活的急转弯，以及偶尔腾空的绝技，把郊狼戏耍一番，洋洋得意。</p>
<p>我正打算把视频转发出去，又看到了那行小字：</p>
<p><strong>疑似使用 AI 生成。</strong></p>
<hr>
<p>我有一种深深的失落。</p>
<p>不是被骗的恼火，而是一种更深的茫然——我知道当下的 AI 视频技术已经炉火纯青，足以以假乱真。面对那些陌生的物种、陌生的环境，我完全无法判断眼前这一切究竟是大自然的鬼斧神工，还是某个人类精心设计的幻觉。</p>
<p>我还有什么可以相信？</p>
<p>我开始想：未来，会不会再也没有真正扎根于森林与海洋的摄影师和记录者？所有人都转型成了导演、编剧。那些用古法拍摄纪录片的人，在这场技术变革里，正在慢慢变成上一个时代的老师傅——预算被削减，流量被侵蚀，存在感日渐式微。</p>
<p>我们享受着 AI 视频带来的惊喜与娱乐，却也在一点点透支视频这种媒介本身的信任。</p>
<p>除了自己的眼睛，除了直播，我越来越难以相信这个时代的任何一段视频。</p>
<p>或许，判断一个视频是不是 AI 的方法，就是默认所有的视频都是 AI。</p>

<p>作者 Santiago 在找工作时，用它评估了 516 个岗位、生成了 631 份报告、最终投递 68 份，拿到了 Head of Applied AI 的 offer。</p>
<p>它吸引我的不只是结果，而是背后的两件事：<strong>他对求职流程的系统化思考，以及他用 Claude Code 构建多智能体协作的方式。</strong></p>
<p><img alt="image-20260409154848524" loading="lazy" src="/posts/career-ops-how-to-build-ai-job-hunting-tool/image-20260409154848524.png"></p>
<hr>
<h2 id="求职的系统化思考">求职的系统化思考</h2>
<h3 id="找工作包含大量的重复劳动">找工作包含大量的重复劳动</h3>
<p>Santiago 的核心洞察很朴素：求职中 70% 的工作是重复的分析劳动，而不是决策。读岗位描述、映射自己的技能、判断匹配度、改简历、填表单，这些动作每个岗位都要重复一遍。</p>
<p>他的数据也验证了这一点：631 份评估报告中，74% 的 offer 得分低于 4.0（满分 5.0）。也就是说，如果没有系统化筛选，大量时间会花在根本不合适的机会上。</p>
<p><img alt="Real evaluation: Datadog Staff AI Engineer, MCP Services — Score 4.55/5, archetype AI Platform + Agentic Workflows, role summary with 7 dimensions" loading="lazy" src="/posts/career-ops-how-to-build-ai-job-hunting-tool/datadog.webp"></p>
<h3 id="评估框架先于行动">评估框架先于行动</h3>
<p>他设计了一套 10 维加权评分体系，其中角色匹配和技能匹配是最关键的指标——不匹配直接 pass。其余维度包括资历、薪酬、公司阶段等。</p>
<p>这个框架的价值在于：把&quot;什么是好机会&quot;从直觉判断，变成了可执行的结构化标准。</p>
<p><img alt="image-20260409154940415" loading="lazy" src="/posts/career-ops-how-to-build-ai-job-hunting-tool/image-20260409154940415.png"></p>
<h3 id="简历是论证不是文档">简历是论证，不是文档</h3>
<p>他不是拿着一份简历到处投，而是基于每个岗位动态生成简历：从岗位描述中提取 15-20 个关键词，识别岗位属于 6 个工作方向中的哪一个，然后按相关性重排经历的优先级制。</p>
<p>同一份经历，不同的框架。他的原则是：<strong>什么都不编造，只是让最相关的证据出现在最显眼的位置。</strong></p>
<p><img alt="image-20260409155000625" loading="lazy" src="/posts/career-ops-how-to-build-ai-job-hunting-tool/image-20260409155000625.png"></p>
<hr>
<h2 id="用-claude-code-构建这套系统">用 Claude Code 构建这套系统</h2>
<h3 id="多个模式只用一个-skill-路由">多个模式，只用一个 Skill 路由</h3>
<p>Santiago 采用了渐进式披露的方式：把所有指令放进 <code>CLAUDE.md</code>，统一通过 <code>career-ops</code> skill 进行路由，再按模式注入额外参数。</p>
<p><code>modes/</code> 目录下有 14 个 <code>.md</code> 文件，负责精准的动态上下文注入。这给了我一个启发：<strong>并不是所有内容都要设计成 skill，直接作为 MD 文件保存在项目里，需要时注入调用就够了。</strong></p>
<p><img alt="image-20260409155531716" loading="lazy" src="/posts/career-ops-how-to-build-ai-job-hunting-tool/image-20260409155531716.png"></p>
<h3 id="ai-做推理脚本做确定性">AI 做推理，脚本做确定性</h3>
<p>AI 擅长评估和生成，但数据合并、去重这类需要确定性结果的操作，Santiago 选择用传统脚本来做——<code>verify-pipeline.mjs</code> 负责监控检查，<code>dedup-tracker.mjs</code> 按 <code>company+role</code> 去重。</p>
<p>同一个岗位可能在不同平台多次发布，他的实践中共发生了 680 次重复 URL 的去重。这件事比任何评分优化都能节省更多时间。</p>
<h3 id="批处理粗暴但可控的并行">批处理：粗暴但可控的并行</h3>
<p>Santiago 没有用 Claude Code 自带的 <code>/batch</code>，也没有设计 sub-agent 来完成批量调用。他的方案更&quot;粗暴&quot;：用 <code>batch-runner.sh</code> 通过 tmux 同时开多个会话，每个会话跑一个 <code>claude -p</code>，再用 <code>batch-state.tsv</code> 追踪谁完成、谁失败。</p>
<p>sub-agent（Task 工具）是在同一个 Claude Code 会话内部派生子任务，共享上下文窗口，受主进程调度；<code>claude -p</code> 则完全绕过会话管理，在操作系统层面用 bash 做进程编排。代价是每个 worker 需要手动事先编排好上下文——但好处是并行度和容错性更强。</p>
<p><img alt="image-20260409160343058" loading="lazy" src="/posts/career-ops-how-to-build-ai-job-hunting-tool/image-20260409160343058.png"></p>
<hr>
<h2 id="对我的启发">对我的启发</h2>
<p>Career-Ops 让我看到的不只是一个求职工具，而是一种用 Claude Code 构建领域系统的方法论——把复杂工作流拆成独立的 mode 文件，用路由表分发而非堆砌 skill；AI 做推理和生成，脚本做确定性操作，各取所长；批处理用 conductor-worker 模式， worker prompt 自包含，文件系统做通信。</p>
<p>这些经验不只适用于求职场景——但可以迁移的是思维方式，不是这套工具本身。</p>

<p>最近我看到了一个十分有趣的多 agent 项目——三省六部制，首先用户是皇上，不论怎么讲，先过一把登基的瘾。它任命了一个太子，专门负责消息的分拣分发，平时和你闲聊，需要的时候就给下面派任务。下面有三省（中书·门下·尚书）：负责需求规划，质量品控，任务调度。 最后还有执行六部（现在加了一个早朝官，变七部了），分别执行代码编写、bug 修复、数据处理，对任务进行了细致的划分，一个部门掌握一小摊。</p>
<p>先不管效果怎么样，如果早朝的时候，所有agent都先说一遍吾皇万岁万岁万万岁，那这个系统还是提供情绪价值的。相关的帖子下面，最有趣的评论莫过于，这套系统最大的问题就是容易导致token爆炸，国库空虚🤣。</p>
<p>在这个有趣的开源项目之外，我开始思考一个问题：人类的分工套用在agent上是不是合适的？</p>
<hr>
<h2 id="人类为什么进行分工">人类为什么进行分工</h2>
<p>亚当·斯密在《国富论》开篇第一章便是论分工，他开宗明义地提到：劳动生产力最大的进步都是分工的结果。在亚当·斯密观察大头针工厂时，他发现当一个人试图完成所有工序，其效率远远低于一群各司其职的专人。当一个人专心完成一个工序时，经验的增长，判断力的提高，都进一步地提高生产力。</p>
<p>因此，当人类让 agent 深度参与自己的工作时，第一个想到的就是将全链条的工作进行切分。以市场调研为例，很多人设计的多 agent 工作流会包括：调研员（收集信息）、分析师（整理洞察）、策略师（给建议）、文案（写提案）——因为在正常人类社会中，这些本就由不同工种各自完成。</p>
<p>这个直觉很自然。但 AI 的&quot;分工&quot;，真的和人类的分工是一回事吗？</p>
<hr>
<h2 id="ai-分工面临的独特问题">AI 分工面临的独特问题</h2>
<h3 id="拆分越多丢失越多">拆分越多，丢失越多</h3>
<p>人类分工时，交接的是信息——一份文件、一个结论、一条指令。但 AI 在完成任务的过程中，积累的不只是信息，还有<strong>感知</strong>：在收集素材过程中形成的判断、在反复尝试中建立的路径感知。这些东西很难打包交接。</p>
<p>还是以市场调研为例。调研员 agent 在收集信息的过程中，会注意到某个数据的异常、某个用户反馈的微妙差异——这些构成了它对这个市场的&quot;感知&quot;。但当它把一份调研报告交给下一个分析师 agent 时，报告里有数据，没有这些感知。分析师拿到的是结论，不是过程；是表格，不是直觉。当一个多 agent 流水线把任务拆开，上一个节点往往只将最终产出交给下一个节点，而上下文信息在交接中被稀释掉了。拆得越细，丢失的越多。</p>
<h3 id="上下文够大之后">上下文够大之后</h3>
<p>多 agent 架构最初流行，有一个很实际的工程原因：早期模型的上下文窗口很小，一个 agent 根本装不下一条完整链路所需的信息，只能拆开来各管一段。</p>
<p>但现在的模型，上下文窗口已经足够大，能力也足够强，一个 agent 完全可以从头到尾完成整条链路上的工作。那些因为&quot;装不下&quot;而拆分的理由，正在逐渐失效。</p>
<p>不过，上下文边界并没有消失，只是变得更隐蔽。当 agent 发现自己接近上下文边界，它甚至会开始&quot;恐慌&quot;——着急把任务结束，以免撞上限制。OpenClaw 创始人 Peter Steinberger 在采访中提到，他会跟 agent 说&quot;take it slow，慢慢来&quot;。如果不这么说，agent 会在 thinking 里念叨&quot;哦，我的上下文快接近上限了，所以我需要……&ldquo;然后仓皇收尾。&ldquo;慢慢来&rdquo;，成了他工作流里神奇的提示词工程的一部分。</p>
<h3 id="角色隔离是值得主动设计的">角色隔离是值得主动设计的</h3>
<p>当然，有一种拆分是值得的：<strong>构建者与评估者的分离</strong>。</p>
<p>agent 在完成自己的任务之后，往往会自信地说&quot;我干得不错&rdquo;。这时候，就需要另一个带有空白上下文的 agent 来审视它——由于没有过去构建时的路径依赖，它更容易发现问题，也更容易提出结构化的意见。</p>
<p>这不是模拟人类的&quot;质检部门&quot;，而是利用了 AI 的一个特性：全新的上下文，意味着全新的眼光。</p>
<hr>
<h2 id="专家实践peter-的轻管理方案">专家实践：Peter 的「轻管理」方案</h2>
<p>我不想泛泛地讨论理论。Anthropic、LangChain 的博客里有很多类似的分析，最近关于 Harness Engineering 的讨论也受到了关注。让我们看看真正在用多 agent 工作流做出现象级应用的人是怎么做的。</p>
<p>Peter Steinberger 用多 agent 工作流开发了 OpenClaw。他在一个 3×3 的终端网格里并行运行 3 到 8 个 agent——但是，他没有一个主 agent 充当&quot;太子&quot;做大脑、做管理、做分配。他自己就是那个 main agent。</p>
<p>他对 background agents（后台自动跑的 agent）持明确的保留态度：因为他需要实时观察 agent 的走向，一旦发现偏离就立刻按 Escape 介入。这不是能力不够的问题——他每月花费上千美元订阅，拥有多个 ChatGPT 和 Claude 的最昂贵套餐，使用目前最聪明的模型，也从来没有做甩手掌柜，让它们无限制地自行运行。</p>
<p>他对分工的理解是：<strong>人作为质检者和方向控制器，agent 作为执行加速器。</strong></p>
<hr>
<h2 id="我们需要怎样的多-agent-1">我们需要怎样的多 agent</h2>
<p>这让我想起强化学习奠基人 Rich Sutton 在 2019 年写下的《The Bitter Lesson》——计算领域最著名的文章之一，苦涩的教训。他的核心结论是：人类用领域知识和精巧工程来&quot;指导&quot;AI 的那些努力，最终都败给了算力的暴力碾压。那些看起来聪明的人工设计，一次次被更大的计算规模所淘汰。</p>
<p>这个教训放到多 agent 设计上同样成立：越是精心模拟人类组织架构的复杂层级，越会随着模型本身的进化而失去意义。随意堆砌 agent 的数量，迎来的不是分工带来的效率提升，而是患上了大公司病——分工变成了互相推诿，每个节点都在等上一个节点，没有人真正在推进执行。</p>
<p>那什么样的多 agent 是值得设计的？</p>
<p><strong>串行认知隔离</strong>：提案者与评估者分开跑，各自拥有独立的上下文。不是因为模拟了人类的&quot;复核机制&quot;，而是因为 AI 评价自己的工作时，往往都说&quot;我做得不错&quot;——一个空白上下文的审视者，比任何 prompt 技巧都更有效。</p>
<p><strong>并行子任务</strong>：天然适合多 agent 的场景，用于提高速度。任务之间相互独立，并行不会带来上下文损耗，这才是真正的效率收益。</p>
<p>回到那个三省六部制的项目，正所谓登基易，治国难。当 agent 们忙成一锅粥，token 哗哗地烧，你是否还知道自己想要什么，看得出哪里跑偏，知道什么时候该伸手打断？</p>
<p>真正懂多agent的人，不是在享受登基的仪式感，而是知道什么时候该亲自出手——就像Peter按下Escape那一刻。</p>

<h2 id="归去来兮">归去来兮</h2>
<p>姜文在《邪不压正》里借人物之口说：「正经人谁写日记呀？写出来的哪能叫心里话？」</p>
<p>或许因为这句台词，潜意识里自己也觉得写日记下贱，所以很长一段时间里，我几乎停止了用文字表达自己。</p>
<p>我记得我高中的时候其实很喜欢写日记，那个时候想到什么写什么，有些同学苦于没有素材完成每日日记的作业，我学鲁迅论这个，论那个，看到什么都想论一论，都想谈一谈。后来，大学之后，文字就彻底变成了工具——课堂笔记、题型手册、知识框架，逐步养成了把知识体系化的习惯：在脑海里画一张思维导图，把论点、论据全部结构化。高效，清晰，但从来没有整理成文章。</p>
<p>后来，我的爱人问我：为什么写日记就下贱，为什么表达自己要被负面的指责。</p>
<p>这让我重新审视这句台词，重新思考写作本身。</p>
<p>真正让我开始动笔的，是因为我接触了 Daniel Miessler 的博客。他写 AI，写生活，写自己对世界的理解。他把写作作为一项重要的技能。</p>
<p>在他的启发下，我开始写一些东西，发在小红书和微信公众号上。有流量，有反馈，但真正让我觉得值得的，是我在书写的过程中，重新梳理自己的逻辑，想方设法的把它以幽默、缜密的方式表达出来。我写的支支吾吾，发现某些自以为想清楚的东西，其实只是一堆散乱的素材。把它们倒出来、整理成文章的过程，我对自己所讨论的议题有了更清楚的认识。</p>
<p><strong>知识外化</strong>，这是我写作带给我最大的收获。</p>
<h2 id="流量是一只猫">流量是一只猫</h2>
<p>做小红书的过程里，我也品尝过被流量牵着走的滋味。</p>
<p>有一两篇文章获得了关注，粉丝慢慢积累。我开始盯着后台，看今天又涨了几个。后来，可能因为我的网感欠佳，可能因为停更过，可能因为平台希望我花钱买流量——总之，最近的文章反馈不错，曝光却越来越少。</p>
<p>我特别喜欢的一位雕塑手绘博主遇到了同样的困惑。他把小红书的流量比作一只猫：</p>
<blockquote>
<p><strong>你不搭理它，它主动来蹭你。你追着要抱它，它高昂着尾巴走开。</strong></p></blockquote>
<p>我喜欢这个比喻。同时也引起我的思考：</p>
<p>如果写作的根本动力是知识外化，那粉丝与否、曝光多少、点赞数量，就不应该是我坐下来写字的理由。</p>
<p><strong>不被算法管的地方</strong>——这不就是博客？</p>
<h2 id="你好世界">你好，世界</h2>
<p>这是这个博客最开始的地方，这是我的博客和互联网说Hello world的地方。</p>
<p>我有很多想写的东西，关于 AI, 关于投资。</p>
<p>过去，如果你想研究一个领域，需要大量时间做基础功课。现在，这些基础功课 AI 能替你快速完成。人可以把更多精力放在底层逻辑的探索上、更高效方法论的构建上。</p>
<p>那些转瞬即逝的领域知识，不再是绊住你前进的石头——在 AI 的帮助下，它们成了了解这个世界的垫脚石。</p>
<p>我想把这个探索的过程写下来。</p>
<p>Daniel Miessler 的博客最早写于 1999 年，他关于人生与世界观的分享，让我受益良多。</p>
<p>我希望我也能像他一样，写很多年，写很多东西。为了我，或许也为了这个世界。</p>
<p>你好，世界。</p>
