What Click Path Audit does

Click Path Audit is a specialized tool designed for developers seeking to uncover defects in user interface interactions that traditional debugging methods often overlook. It meticulously tracks the state changes triggered by user actions, such as button clicks and form submissions, to ensure that the final UI state aligns with user expectations. This skill is particularly useful in scenarios where users report issues with button functionality that do not manifest as conventional errors, such as missing connections or runtime failures. By auditing the interactions, developers can pinpoint subtle bugs that arise from shared state interactions, silent rollbacks, or race conditions between function calls.

The auditing process involves a systematic approach to each interactive touchpoint within the application. It identifies the handling functions associated with user actions and traces each function call in sequence. The skill evaluates the state read and written by each function, checking for side effects that might unintentionally reset or alter the expected state. This comprehensive analysis helps developers detect whether a subsequent function call negates the effect of a previous one, ensuring that the final state reflects the intended user experience. For example, a button designed to create a new email might call two functions that work correctly in isolation but conflict with each other, resulting in no visible action.

Click Path Audit is best utilized during significant application changes, such as after a major refactor or before a release, to validate key user flows. It is particularly effective in environments using shared state management libraries like Zustand or Redux, where state interactions can become complex and lead to unexpected results. By providing detailed reports on identified issues, including severity levels and suggested fixes, this skill empowers developers to improve the reliability and user experience of their applications.

However, it is important to note that Click Path Audit is not suitable for diagnosing API-level defects, style/layout issues, or performance-related concerns. For these types of problems, other debugging or performance analysis tools should be employed. This skill excels in environments where user interface interactions are critical and where traditional debugging may fall short in revealing underlying issues.

When to use it

Use this skill when users report UI issues that don't trigger conventional errors, especially after significant code changes.

When not to use it

Avoid using it for API-level problems, style issues, or performance-related debugging.

What you can build with it

Post-Refactor Validation

After a major code refactor, use Click Path Audit to ensure that UI interactions still function as intended.

User Reported Issues

When users report that buttons are unresponsive, employ this skill to trace the interactions and identify hidden bugs.

Pre-Release Testing

Before deploying a new version of your application, run Click Path Audit to validate key user flows and catch any potential issues.

/click-path-audit — 行为流审计

发现静态代码审查遗漏的缺陷:状态交互副作用、顺序调用间的竞态条件,以及相互静默撤销的处理程序。

解决的问题

传统调试检查:

  • 函数是否存在?(缺少连接)
  • 是否崩溃?(运行时错误)
  • 是否返回正确类型?(数据流)

但未检查:

  • 最终 UI 状态是否与按钮标签承诺一致?
  • 函数 B 是否静默撤销了函数 A 刚刚执行的操作?
  • 共享状态(Zustand/Redux/context)是否存在抵消预期操作的副作用?

真实案例:一个"新邮件"按钮依次调用了 setComposeMode(true)selectThread(null)。两者单独工作正常。但 selectThread 有一个副作用重置了 composeMode: false。按钮毫无反应。系统化调试发现了 54 个缺陷——这个被遗漏了。


工作原理

针对目标区域内的每个交互触点:

1. 识别处理函数(onClick、onSubmit、onChange 等)
2. 按顺序追踪处理函数中的每个函数调用
3. 对于每个函数调用:
   a. 它读取了哪些状态?
   b. 它写入了哪些状态?
   c. 它是否对共享状态产生了副作用?
   d. 它是否作为副作用重置/清除了任何状态?
4. 检查:后续调用是否会撤销前面调用的状态变更?
5. 检查:最终状态是否符合用户对按钮标签的预期?
6. 检查:是否存在竞态条件(异步调用以错误顺序解析)?

执行步骤

步骤 1:映射状态存储

在审计任何触点之前,构建每个状态存储操作的副作用映射:

对于作用域内的每个 Zustand 存储 / React 上下文:
  对于每个操作/设置器:
    - 它设置了哪些字段?
    - 它是否作为副作用重置了其他字段?
    - 文档:actionName → {sets: [...], resets: [...]}

这是关键参考。"新邮件"缺陷在不知道 selectThread 重置了 composeMode 的情况下是不可见的。

输出格式:

STORE: emailStore
  setComposeMode(bool) → 设置: {composeMode}
  selectThread(thread|null) → 设置: {selectedThread, selectedThreadId, messages, drafts, selectedDraft, summary} 重置: {composeMode: false, composeData: null, redraftOpen: false}
  setDraftGenerating(bool) → 设置: {draftGenerating}
  ...

危险的重置(清除不属于自身状态的操作):
  selectThread → 重置 composeMode(由 setComposeMode 拥有)
  reset → 重置所有内容

步骤 2:审计每个触点

针对目标区域内的每个按钮/开关/表单提交:

TOUCHPOINT: [按钮标签] 在 [组件:行]
  HANDLER: onClick → {
    调用 1: functionA() → 设置 {X: true}
    调用 2: functionB() → 设置 {Y: null} 重置 {X: false}  ← 冲突
  }
  EXPECTED: 用户看到 [按钮标签所承诺的描述]
  ACTUAL: X 为 false,因为 functionB 重置了它
  VERDICT: BUG — [描述]

检查以下每种缺陷模式:

模式 1:顺序撤销

handler() {
  setState_A(true)     // 设置 X = true
  setState_B(null)     // 副作用:重置 X = false
}
// 结果:X 为 false。第一次调用毫无意义。

模式 2:异步竞态

handler() {
  fetchA().then(() => setState({ loading: false }))
  fetchB().then(() => setState({ loading: true }))
}
// 结果:最终的 loading 状态取决于哪个先完成

模式 3:过期闭包

const [count, setCount] = useState(0)
const handler = useCallback(() => {
  setCount(count + 1)  // 捕获了过时的 count
  setCount(count + 1)  // 同样的过时 count — 只增加 1,而不是 2
}, [count])

模式 4:缺失状态转换

// 按钮显示"保存",但处理程序仅验证,从未实际保存
// 按钮显示"删除",但处理程序设置了一个标志而未调用API
// 按钮显示"发送",但API端点已被移除/损坏

模式 5:条件死路径

handler() {
  if (someState) {        // 此时 someState 始终为 false
    doTheActualThing()    // 永远不会执行到
  }
}

模式 6:useEffect 干扰

// Button 设置 stateX = true
// useEffect 监听 stateX 并将其重置为 false
// 用户看不到任何变化

步骤 3:报告

针对发现的每个缺陷:

CLICK-PATH-NNN: [严重性: 严重/高/中/低]
  触点: [按钮标签] 位于 [文件:行号]
  模式: [顺序撤销 / 异步竞态 / 过期闭包 / 缺失过渡 / 死路径 / useEffect 干扰]
  处理函数: [函数名或内联]
  追踪:
    1. [调用] → 设置 {字段: 值}
    2. [调用] → 重置 {字段: 值}  ← 冲突
  预期: [用户期望的结果]
  实际: [实际发生的结果]
  修复: [具体修复方案]

范围控制

此审计成本较高。请适当限定范围:

  • 全应用审计: 在发布或重大重构后使用。按页面启动并行代理。
  • 单页面审计: 在构建新页面或用户报告按钮失效后使用。
  • 存储聚焦审计: 在修改 Zustand 存储后使用——审计所有使用已更改操作的消费者。

全应用推荐的代理拆分:

Agent 1:映射所有状态存储(步骤 1)——这是所有其他代理的共享上下文
Agent 2:仪表盘(任务、笔记、日志、想法)
Agent 3:聊天(DanteChatColumn、JustChatPage)
Agent 4:邮件(ThreadList、DraftArea、EmailsPage)
Agent 5:项目(ProjectsPage、ProjectOverviewTab、NewProjectWizard)
Agent 6:CRM(所有子标签页)
Agent 7:个人资料、设置、保险库、通知
Agent 8:管理套件(所有页面)

代理 1 必须首先完成。其输出是所有其他代理的输入。


何时使用

  • 系统化调试发现"无缺陷"但用户报告 UI 失效后
  • 修改任何 Zustand 存储操作后(检查所有调用者)
  • 任何涉及共享状态的重构后
  • 发布前,针对关键用户流程
  • 当按钮"无反应"时——这是解决该问题的工具

何时不使用

  • 针对 API 级别缺陷(错误的响应结构、缺失端点)——使用系统化调试
  • 针对样式/布局问题——视觉检查
  • 针对性能问题——性能分析工具

与其他技能的集成

  • /superpowers:systematic-debugging(发现其他 54 种缺陷类型)之后运行
  • /superpowers:verification-before-completion(验证修复是否有效)之前运行
  • 反馈至 /superpowers:test-driven-development——此处发现的每个缺陷都应添加测试

示例:启发此技能的缺陷

ThreadList.tsx "新邮件"按钮:

onClick={() => {
  useEmailStore.getState().setComposeMode(true)   // ✓ 设置 composeMode = true
  useEmailStore.getState().selectThread(null)      // ✗ 重置 composeMode = false
}}

存储定义:

selectThread: (thread) => set({
  selectedThread: thread,
  selectedThreadId: thread?.id ?? null,
  messages: [],
  drafts: [],
  selectedDraft: null,
  summary: null,
  composeMode: false,     // ← 这个静默重置导致按钮失效
  composeData: null,
  redraftOpen: false,
})

系统化调试遗漏了它,因为:

  • 按钮有 onClick 处理程序(未失效)
  • 两个函数都存在(无缺失连接)
  • 两个函数均未崩溃(无运行时错误)
  • 数据类型正确(无类型不匹配)

点击路径审计捕获了它,因为:

  • 步骤 1 映射出 selectThread 重置了 composeMode
  • 步骤 2 追踪处理程序:调用 1 设置为 true,调用 2 重置为 false
  • 判定:顺序撤销——最终状态与按钮意图矛盾
