+# 设计文档：office-agent 文档生成/编辑 Workflow 体系
+
+**日期：** 2026-05-18
+
+---
+
+## 概述
+
+在 monorepo 中新增三个包，实现通过 `office-agent` CLI 生成或编辑 Word 文档的完整 workflow 体系。
+
+| 包 | npm name | 职责 |
+|---|---|---|
+| `workflow-template-document` | `@uncaged/workflow-template-document` | 纯结构：角色定义、meta schema、调度表、descriptor |
+| `workflow-agent-office` | `@uncaged/workflow-agent-office` | writer 角色执行器：调用 `office-agent` CLI |
+| `workflow-agent-docx-diff` | `@uncaged/workflow-agent-docx-diff` | differ 角色执行器：调用 `docx-diff` CLI |
+
+Template 只定义结构，不含执行逻辑。执行器与 template 解耦。
+
+---
+
+## 一、`workflow-template-document`
+
+### Thread 启动输入
+
+```typescript
+// src/types.ts
+type DocumentStartInput = {
+  prompt: string;           // 用户指令
+  inputDocx: string | null; // null = 生成模式；本机绝对路径 = 编辑模式
+};
+```
+
+start.content 为 JSON `{ prompt, inputDocx }` 或纯文本（fallback：generate 模式，整段作为 prompt）。
+
+### 角色与 Meta
+
+`WriterMeta` 使用 discriminated union，在 schema 层区分两种模式：
+
+```typescript
+const writerMetaSchema = z.discriminatedUnion("mode", [
+  z.object({
+    mode: z.literal("generate"),
+    outputDocx: z.string(),   // 生成产物绝对路径
+    sourceDocx: z.null(),
+  }),
+  z.object({
+    mode: z.literal("edit"),
+    outputDocx: z.string(),   // 修改后产物：<outputDir>/modified.docx
+    sourceDocx: z.string(),   // 原始副本：<outputDir>/original.docx
+  }),
+]);
+type WriterMeta = z.infer<typeof writerMetaSchema>;
+
+// differ：仅编辑模式执行
+const differMetaSchema = z.object({
+  sourceDocx: z.string(),
+  modifiedDocx: z.string(),
+  diffDocx: z.string(),
+});
+type DifferMeta = z.infer<typeof differMetaSchema>;
+```
+
+两个角色的 `systemPrompt` 均为 `""`。
+
+### 调度表
+
+```
+START → writer ──(mode = "edit")──→ differ → END
+               ↘(mode = "generate")→ END
+```
+
+### 公开导出
+
+template 导出两个对象供消费方使用：
+
+- `documentWorkflowDefinition: WorkflowDefinition<DocumentMeta>` — 传入 `createWorkflow` 的 `def` 参数
+- `buildDocumentDescriptor(): WorkflowDescriptor` — bundle 导出用
+
+```typescript
+// bundle 侧用法
+export const descriptor = buildDocumentDescriptor();
+export const run = createWorkflow(documentWorkflowDefinition, { adapter, overrides });
+```
+
+### 包文件结构
+
+```
+packages/workflow-template-document/
+  src/
+    types.ts           # DocumentStartInput
+    roles/
+      writer.ts        # writerMetaSchema, WriterMeta, writerRole
+      differ.ts        # differMetaSchema, DifferMeta, differRole
+      index.ts
+    roles.ts           # DocumentMeta, documentRoles
+    moderator.ts       # writerIsEditMode condition + documentTable
+    definition.ts      # documentWorkflowDefinition
+    descriptor.ts      # buildDocumentDescriptor()
+    index.ts
+  __tests__/
+    moderator.test.ts
+  package.json
+  tsconfig.json
+```
+
+### 依赖
+
+```json
+{
+  "@uncaged/workflow-protocol": "workspace:^",
+  "@uncaged/workflow-runtime": "workspace:^",
+  "@uncaged/workflow-register": "workspace:^",
+  "zod": "^4.0.0"
+}
+```
+
+---
+
+## 二、`workflow-agent-office`
+
+### office-agent CLI 接口
+
+```bash
+# 生成模式：在 CWD 生成 output.docx
+office-agent create "<prompt>" -o output.docx
+
+# 编辑模式：在 CWD 对 modified.docx 进行修改（覆写）
+office-agent edit modified.docx "<instruction>"
+```
+
+- 两个命令均为阻塞调用（CLI 内部消费 SSE，退出即完成）
+- 输出文件落到调用方设定的 CWD
+- 退出码 0 = 成功，非零 = 失败
+
+### 文件命名约定
+
+| 模式 | 文件 | 路径 |
+|---|---|---|
+| generate | 输出 | `<outputDir>/output.docx` |
+| edit | 原始副本（workflow-owned 快照） | `<outputDir>/original.docx` |
+| edit | 修改后产物 | `<outputDir>/modified.docx` |
+
+edit 模式先将 `inputDocx` 复制为 `original.docx`（不可变快照），再复制为 `modified.docx`，对 `modified.docx` 调用 CLI。agent 覆写 `modified.docx`，`original.docx` 保持不变。differ 对比这两个 workflow-owned 文件，不依赖用户原始路径。
+
+### 执行流程
+
+**生成模式（`inputDocx = null`）：**
+1. `mkdir -p <outputDir>`（`<config.outputDir>/<ctx.threadId>`）
+2. `const command = config.command ?? "office-agent"`
+3. `spawnCli(command, ["create", prompt, "-o", "output.docx"], { cwd: outputDir, timeoutMs })`
+4. 验证 `outputDir/output.docx` 存在
+5. 返回 `JSON.stringify({ mode: "generate", outputDocx, sourceDocx: null })`
+
+**编辑模式（`inputDocx ≠ null`）：**
+1. `mkdir -p <outputDir>`
+2. `copyFile(inputDocx, <outputDir>/original.docx)`
+3. `copyFile(inputDocx, <outputDir>/modified.docx)`
+4. `const command = config.command ?? "office-agent"`
+5. `spawnCli(command, ["edit", "modified.docx", prompt], { cwd: outputDir, timeoutMs })`
+6. 验证 `outputDir/modified.docx` 存在
+7. 返回 `JSON.stringify({ mode: "edit", outputDocx: modifiedPath, sourceDocx: originalPath })`
+
+### AdapterFn 实现（直接实现，不经过 runtime.extract）
+
+CLI 产出确定性 JSON，直接 `schema.parse(JSON.parse(raw))` 跳过 LLM extraction：
+
+```typescript
+export function createOfficeAgent(config: OfficeAgentConfig): AdapterFn {
+  return <T>(_systemPrompt: string, schema: z.ZodType<T>) =>
+    async (ctx: ThreadContext, _runtime: WorkflowRuntime): Promise<RoleResult<T>> => {
+      const { prompt, inputDocx } = parseStartInput(ctx.start.content);
+      const raw = await runOfficeAgent(config, ctx.threadId, prompt, inputDocx);
+      const meta = schema.parse(JSON.parse(raw)) as T;
+      return { meta, childThread: null };
+    };
+}
+```
+
+`_systemPrompt` 为 writer 角色的 systemPrompt（空字符串），实际指令从 `ctx.start.content` 解析。
+
+### 配置
+
+```typescript
+type OfficeAgentConfig = {
+  outputDir: string;        // 输出根目录，runner 在此下按 threadId 建子目录
+  command: string | null;   // null → runner 内 resolve 为 "office-agent"
+  timeout: number | null;   // null → 不设超时；单位 ms
+};
+```
+
+### 错误处理
+
+```typescript
+if (!result.ok) {
+  const e = result.error;
+  if (e.kind === "non_zero_exit")
+    throw new Error(`office-agent failed (exit ${e.exitCode}): ${e.stderr}`);
+  if (e.kind === "timeout")
+    throw new Error("office-agent: timed out");
+  // "spawn_failed"
+  throw new Error(`office-agent: spawn failed: ${e.message}`);
+}
+if (!existsSync(expectedPath))
+  throw new Error(`office-agent: output file not found: ${expectedPath}`);
+```
+
+### packageDescriptor
+
+```typescript
+// src/package-descriptor.ts
+export const packageDescriptor: PackageDescriptor = {
+  name: "@uncaged/workflow-agent-office",
+  version: "0.1.0",
+  capabilities: ["office-agent-cli", "docx-generate", "docx-edit"],
+  configSchema: {
+    type: "object",
+    required: ["outputDir"],
+    properties: {
+      outputDir: { type: "string", description: "Root directory for workflow outputs." },
+      command:   { anyOf: [{ type: "string" }, { type: "null" }], description: "Path to office-agent CLI; null uses PATH." },
+      timeout:   { anyOf: [{ type: "number" }, { type: "null" }], description: "Timeout in ms; null means no limit." },
+    },
+    additionalProperties: false,
+  },
+};
+```
+
+### 包文件结构
+
+```
+packages/workflow-agent-office/
+  src/
+    types.ts                # OfficeAgentConfig, OfficeAgentOpt
+    runner.ts               # runOfficeAgent()（spawnCli 封装 + 文件验证）
+    agent.ts                # createOfficeAgent(): AdapterFn
+    package-descriptor.ts   # packageDescriptor
+    index.ts
+  __tests__/
+    runner.test.ts
+    agent.test.ts
+  package.json
+  tsconfig.json
+```
+
+### 依赖
+
+```json
+{
+  "@uncaged/workflow-protocol": "workspace:^",
+  "@uncaged/workflow-util": "workspace:^",
+  "@uncaged/workflow-util-agent": "workspace:^"
+}
+```
+
+---
+
+## 三、`workflow-agent-docx-diff`
+
+`differ` 角色专用执行器。从 `ctx.steps` 读取 `WriterMeta`，调用本地 `docx-diff` CLI。
+
+### docx-diff 退出码约定
+
+| 退出码 | 含义 | runner 处理 |
+|---|---|---|
+| 0 | 无差异 | 正常，验证 diffDocx 存在 |
+| 1 | 有差异 | 正常（显式处理为成功），验证 diffDocx 存在 |
+| 2+ | 错误 | throw |
+
+runner 收到 `SpawnCliError { kind: "non_zero_exit", exitCode: 1 }` 时视为成功，验证文件后继续；`exitCode >= 2` 才 throw。
+
+### 执行流程
+
+```
+1. 从 ctx.steps 找到 writer 步骤，读取 WriterMeta
+2. 验证 mode === "edit"（否则 throw）
+3. diffDocx = join(dirname(writer.outputDocx), "diff.docx")
+4. const command = config.command ?? "docx-diff"
+5. spawnCli(command,
+     [writer.sourceDocx, writer.outputDocx, "--output", "docx", "--out-file", diffDocx],
+     { cwd: null, timeoutMs: null })
+   exit 0 或 1 → 验证 diffDocx 存在
+   exit 2+ → throw
+6. 返回 JSON.stringify({ sourceDocx, modifiedDocx: writer.outputDocx, diffDocx })
+```
+
+### AdapterFn 实现（直接实现，不经过 runtime.extract）
+
+```typescript
+export function createDocxDiffAgent(config: DocxDiffAgentConfig = { command: null }): AdapterFn {
+  return <T>(_prompt: string, schema: z.ZodType<T>) =>
+    async (ctx: ThreadContext, _runtime: WorkflowRuntime): Promise<RoleResult<T>> => {
+      const writerStep = ctx.steps.find(s => s.role === "writer");
+      if (!writerStep) throw new Error("differ: no writer step found");
+      const writerMeta = writerStep.meta as WriterMeta;
+      if (writerMeta.mode !== "edit")
+        throw new Error("differ: writer did not run in edit mode");
+      const raw = await runDocxDiff(config, writerMeta);
+      const meta = schema.parse(JSON.parse(raw)) as T;
+      return { meta, childThread: null };
+    };
+}
+```
+
+### 配置
+
+```typescript
+type DocxDiffAgentConfig = {
+  command: string | null;   // null → runner 内 resolve 为 "docx-diff"
+};
+```
+
+### packageDescriptor
+
+```typescript
+export const packageDescriptor: PackageDescriptor = {
+  name: "@uncaged/workflow-agent-docx-diff",
+  version: "0.1.0",
+  capabilities: ["docx-diff-cli", "docx-diff-report"],
+  configSchema: {
+    type: "object",
+    properties: {
+      command: { anyOf: [{ type: "string" }, { type: "null" }], description: "Path to docx-diff CLI; null uses PATH." },
+    },
+    additionalProperties: false,
+  },
+};
+```
+
+### 包文件结构
+
+```
+packages/workflow-agent-docx-diff/
+  src/
+    types.ts                # DocxDiffAgentConfig
+    runner.ts               # runDocxDiff()（exit 1 处理 + 文件验证）
+    agent.ts                # createDocxDiffAgent(): AdapterFn
+    package-descriptor.ts   # packageDescriptor
+    index.ts
+  __tests__/
+    runner.test.ts
+    agent.test.ts
+  package.json
+  tsconfig.json
+```
+
+### 依赖
+
+```json
+{
+  "@uncaged/workflow-protocol": "workspace:^",
+  "@uncaged/workflow-util-agent": "workspace:^",
+  "@uncaged/workflow-template-document": "workspace:^"
+}
+```
+
+---
+
+## 四、外部 bundle（外部 workspace 消费）
+
+```typescript
+import { createOfficeAgent } from "@uncaged/workflow-agent-office";
+import { createDocxDiffAgent } from "@uncaged/workflow-agent-docx-diff";
+import {
+  buildDocumentDescriptor,
+  documentWorkflowDefinition,
+} from "@uncaged/workflow-template-document";
+import { createWorkflow } from "@uncaged/workflow-runtime";
+import { getDefaultWorkflowStorageRoot } from "@uncaged/workflow-util";
+import { join } from "node:path";
+
+const outputDir = join(getDefaultWorkflowStorageRoot(), "outputs");
+
+export const descriptor = buildDocumentDescriptor();
+export const run = createWorkflow(documentWorkflowDefinition, {
+  adapter: createOfficeAgent({ outputDir, command: null, timeout: null }),
+  overrides: { differ: createDocxDiffAgent() },
+});
+```
+
+---
+
+## 不在范围内
+
+- 重试逻辑（失败直接 throw）
+- office-agent server 的启停管理（假设 server 已在运行）
+- docx-diff HTML/terminal 格式输出（仅 docx）
+- 跨机器执行（`inputDocx` 须为本机有效绝对路径）
