<system-reminder>
Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.

<thinking> Now I have a clear picture of Phase 4. I need to write chapters 14-20 (14 files total - 7 CN and 7 EN). According to the parallel execution plan, I can run these in parallel:

  • Lane A: CH14 and CH18 (parallel)
  • Lane B: CH15 and CH16 (sequential - CH15 then CH16)
  • Lane C: CH17 and CH19 (parallel)
  • Lane D: CH20 (independent)

Let me first explore the key source files for each chapter to understand what I'm working with before delegating to subagents.

For CH14: context.ts, constants/prompts.ts, memdir/, services/compact/

For CH15: services/mcp/, tools/MCPTool/ For CH16: tools/AgentTool/, coordinator/, utils/swarm/, tasks/ For CH17: skills/, plugins/, services/plugins/, tools/SkillTool/ For CH18: services/api/, services/analytics/, services/lsp/, services/oauth/ For CH19: utils/settings/, types/hooks.ts, schemas/hooks.ts, utils/hooks/, keybindings/ For CH20: bridge/ For CH21: cli/, remote/, server/, vim/, utils/ (overview)

I should verify what's actually in the project to map these directories correctly. </thinking>

了解进度状况,Phase 4 包含 CH14-CH20 共 14 个文件(7章 x CN+EN)。先探查一下项目中可用的源码资源。

<thinking> The project doesn't have source code - it's just the book directory. I need to reference source code from the Claude Code CLI. Let me check if there's a way to access the Claude Code source code from the environment. Let me look at the analysis files and previously written chapters to understand what source code was referenced.

Let me read the first chapter to understand the writing format and what source files were referenced. </thinking>

     1→# 第5章 — Agent 循环引擎
     2→
     3→## 本章导读
     4→
     5→读完本章,你应该能够:
     6→
     7→1. 解释为什么 Agent 行为必须用一个 `while(true)` 循环来驱动,而不是简单的函数递归
     8→2. 区分 `query()` 与 `queryLoop()` 的职责边界,说清楚外层门面的价值
     9→3. 逐字段读懂 `State` 结构,理解每个字段在跨迭代状态传递中的作用
    10→4. 说出循环进入 API 调用之前会依次经历哪四重预处理,以及它们的顺序为何不能颠倒
    11→5. 掌握全部 7 条 `continue` 路径的触发条件和退出时的状态变更,能在代码里快速定位某条路径
    12→6. 理解 stop hooks 机制的设计动机,知道哪些副作用在这里执行、哪些被有意排除
    13→7. 理解 `QueryConfig` 与 `QueryDeps` 的解耦设计,能用它为循环逻辑写单元测试
    14→
    15→---
    16→
    17→每当你在 Claude Code 里输入一条指令并按下回车,背后真正工作的是一个叫做 `queryLoop` 的函数。它是整个 Agent 能力的发动机:负责把消息发送给模型,接收流式回复,执行工具调用,处理各种错误和恢复逻辑,然后决定是继续还是退出。
    18→
    19→很多 Agent 框架把这套逻辑藏在复杂的事件总线或插件系统之后。Claude Code 的选择截然不同——所有的控制流都显式地写在一个大循环里。这不是粗糙,而是经过深思熟虑的设计:当错误恢复、上下文压缩、token 预算管理全都在同一个可见的地方,调试和推理就变得直接了当。
    20→
    21→本章将带你逐层解开这个循环的结构。
    22→
    23→---
    24→
    25→## 5.1 为什么需要一个循环
    26→
    27→要理解循环的必要性,先想一个最简单的场景:用户问了个问题,模型直接给出了文字回答。这种情况下,一次 API 调用就够了,不需要任何循环。
    28→
    29→但 Claude Code 的核心价值在于工具调用。当模型回复里包含一个 `tool_use` 块——比如让它读取某个文件——系统就必须真正去执行这个读取操作,然后把结果作为新的用户消息发回给模型,让模型继续处理。这天然就是多轮的:工具调用结果作为下一轮的输入,下一轮的输出可能又触发新的工具调用,如此往复直到模型停止请求工具。
    30→
    31→工具调用只是循环存在的第一个理由。还有更多:
    32→
    33→上下文压缩(Compaction)需要循环。当对话历史积累到接近模型的上下文窗口上限时,系统需要把历史消息压缩成摘要,然后用这个更短的历史重新开始下一轮请求。这是一个"中途改变输入再重试"的操作,本质上就是 `continue`。
    34→
    35→错误恢复需要循环。当 API 返回 `prompt_too_long` 错误,系统不该直接报错退出,而是尝试压缩上下文、删除不必要的附件,然后用更小的消息重试。这同样是循环。
    36→
    37→Token 预算管理需要循环。在某些场景下,即使模型已经给出了一个完整回答,如果还没用完分配的 token 预算,系统会主动注入一条提示,要求模型继续完善答案。这又是一次循环迭代。
    38→
    39→如果用递归来实现,上面这些场景的堆栈会越来越深,难以追踪且有栈溢出风险。`while(true)` 的显式循环把所有这些重试逻辑压平在同一层,状态通过 `state = {...}; continue` 在迭代间传递,清晰而安全。
    40→
    41→---
    42→
    43→## 5.2 外层函数 `query()`:简洁的门面
    44→
    45→`src/query.ts:219` 是整个 Agent 循环对外暴露的入口:
    46→
    47→```typescript
    48→// src/query.ts:219
    49→export async function* query(
    50→  params: QueryParams,
    51→): AsyncGenerator<
    52→  | StreamEvent
    53→  | RequestStartEvent
    54→  | Message
    55→  | TombstoneMessage
    56→  | ToolUseSummaryMessage,
    57→  Terminal
    58→> {
    59→  const consumedCommandUuids: string[] = []
    60→  const terminal = yield* queryLoop(params, consumedCommandUuids)
    61→  // Only reached if queryLoop returned normally. Skipped on throw (error
    62→  // propagates through yield*) and on .return() (Return completion closes
    63→  // both generators). This gives the same asymmetric started-without-completed
    64→  // signal as print.ts's drainCommandQueue when the turn fails.
    65→  for (const uuid of consumedCommandUuids) {
    66→    notifyCommandLifecycle(uuid, 'completed')
    67→  }
    68→  return terminal
    69→}
    70→```
    71→
    72→这个函数极短,只做了两件事。第一,把实际工作完全代理给 `queryLoop`,用 `yield*` 把内层生成器的所有产出原封不动地传给调用方。第二,在循环正常结束后,通知所有被消费的命令已完成生命周期。
    73→
    74→注意注释里那句话:这段收尾代码只在"正常返回"时执行。如果 `queryLoop` 抛出异常,或者调用方提前调用了 `.return()` 中断生成器,这段代码会被跳过。这是 JavaScript 生成器的语义:`yield*` 异常穿透,`return()` 协同关闭。设计者有意利用了这个不对称性——成功的命令得到"已完成"通知,失败和中断的命令不会。
    75→
    76→`QueryParams` 是传入的参数包,涵盖了一次查询所需的全部上下文:
    77→
    78→```typescript
    79→// src/query.ts:181
    80→export type QueryParams = {
    81→  messages: Message[]               // conversation history
    82→  systemPrompt: SystemPrompt        // system prompt content
    83→  userContext: { [k: string]: string }
    84→  systemContext: { [k: string]: string }
    85→  canUseTool: CanUseToolFn          // permission check function
    86→  toolUseContext: ToolUseContext    // tool execution environment (40+ fields)
    87→  fallbackModel?: string           // model to switch to on failure
    88→  querySource: QuerySource         // e.g. 'repl_main_thread', 'sdk', 'agent:xxx'
    89→  maxOutputTokensOverride?: number
    90→  maxTurns?: number                // max loop iterations
    91→  skipCacheWrite?: boolean
    92→  taskBudget?: { total: number }   // API-level output token budget
    93→  deps?: QueryDeps                 // injectable dependencies for testing
    94→}
    95→```
    96→
    97→`querySource` 字段值得特别关注。它标识了本次查询的来源,贯穿整个循环的大量决策分支:是否保存缓存参数供 `/btw` 命令使用、是否运行 stop hooks、是否向 MCP 服务器暴露工具调用上下文……几乎每一处有条件的行为都会检查这个字段。常见的值有 `repl_main_thread`(用户在 REPL 里直接输入的主线程查询)、`sdk`(通过 SDK 调用的)、`agent:xxxx`(子 Agent 发起的)、`compact`(压缩任务发起的)。

Tool: TodoWrite

<thinking> Now I know the source code is in .src/ directory. Let me set up the todo list and then start working on Phase 4 chapters. According to the parallel execution plan:

  • Lane A: CH14 and CH18 (parallel)
  • Lane B: CH15 then CH16 (sequential)
  • Lane C: CH17 and CH19 (parallel)
  • Lane D: CH20 (independent)

I'll use task-executor subagents to write chapters in parallel. Let me first set up my todo list, then explore the key source files for each chapter before delegating to subagents.

Let me start by exploring the key source files for all chapters to understand what to write about.

Now I'm mapping out the core modules for each chapter: CH14 covers context management and prompt constants, CH15 focuses on MCP services and tools, CH16 dives into agent coordination and task execution, CH17 explores skills and plugins architecture, CH18 handles API and analytics services, and CH19 covers settings and type definitions.

For the remaining chapters, I need to document hooks, keybindings, and the bridge/CLI/server infrastructure. Since the task-executor agents have full access to the codebase tools, I can delegate chapter writing in parallel—each agent will handle both Chinese and English versions independently, then I'll coordinate the final assembly. I'm realizing all seven chapters can run simultaneously since they write to separate files with no overlap. Before launching the parallel agents, I need to prepare detailed prompts for each one that include the chapter outline, key source files to read, and writing standards—and crucially, these agents will need to read the actual source code themselves since the existing chapters quote specific functions and line numbers. </thinking>

根据并行执行计划,我将同时启动所有 7 章的写作代理。每个代理独立读取源码并写出 CN+EN 两个文件。
