+# tracked 任务跟踪模式实现计划
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 在 metadata 中新增 tracked 布尔开关，控制 plan/build/archive 三阶段是否启用 task.md 任务跟踪。
+
+**Architecture:** 在 `RuneConfig.metadata` 新增 `tracked` 字段，默认 `false`，内置默认配置为 `true`。`task-parser.ts` 新增 `validateTaskFormat` 函数做格式校验。`config.ts` 的 `validateConfig` 在 tracked=true 时校验 plan 必须包含 task 文档。`assembler.ts` 的 build/archive 阶段根据 tracked 分支处理。
+
+**Tech Stack:** TypeScript, Bun, bun:test
+
+---
+
+### Task 1: 类型变更 — metadata.tracked
+
+**Files:**
+
+- Modify: `src/types.ts:38-42`
+- Test: `tests/core/config.test.ts`
+
+- [ ] **Step 1: 写失败测试 — validateConfig 在 tracked=true 时要求 plan.documents 包含 task**
+
+在 `tests/core/config.test.ts` 的 `validateConfig` describe 块内追加：
+
+```typescript
+it("tracked=true 时 plan.documents 必须包含 task 文档", () => {
+  const config: RuneConfig = {
+    stages: {
+      plan: {
+        documents: [{ name: "design", prompt: "生成设计" }],
+      },
+    },
+    metadata: { tracked: true },
+  };
+  expect(() => validateConfig(config)).toThrow(ConfigError);
+});
+
+it("tracked=true 且 plan.documents 包含 task 时不报错", () => {
+  const config: RuneConfig = {
+    stages: {
+      plan: {
+        documents: [
+          { name: "design", prompt: "生成设计" },
+          { name: "task", prompt: "生成任务" },
+        ],
+      },
+    },
+    metadata: { tracked: true },
+  };
+  expect(() => validateConfig(config)).not.toThrow();
+});
+
+it("tracked=false 时 plan.documents 不包含 task 也不报错", () => {
+  const config: RuneConfig = {
+    stages: {
+      plan: {
+        documents: [{ name: "design", prompt: "生成设计" }],
+      },
+    },
+    metadata: { tracked: false },
+  };
+  expect(() => validateConfig(config)).not.toThrow();
+});
+
+it("tracked 未配置时等同于 false，不强制要求 task 文档", () => {
+  const config: RuneConfig = {
+    stages: {
+      plan: {
+        documents: [{ name: "design", prompt: "生成设计" }],
+      },
+    },
+  };
+  expect(() => validateConfig(config)).not.toThrow();
+});
+```
+
+- [ ] **Step 2: 运行测试确认失败**
+
+Run: `bun test tests/core/config.test.ts`
+Expected: 新增的 "tracked=true 时 plan.documents 必须包含 task 文档" 测试 FAIL（validateConfig 尚无此校验）
+
+- [ ] **Step 3: 修改 types.ts — metadata 新增 tracked 字段**
+
+在 `src/types.ts` 的 `RuneConfig` 接口中，修改 `metadata` 类型：
+
+```typescript
+export interface RuneConfig {
+  stages: StagesConfig;
+  metadata?: {
+    command?: string;
+    tracked?: boolean;
+  };
+}
+```
+
+- [ ] **Step 4: 修改 config.ts — validateConfig 新增 tracked 校验**
+
+在 `src/core/config.ts` 的 `validateConfig` 函数中，在现有校验逻辑之前追加：
+
+```typescript
+if (config.metadata?.tracked && plan) {
+  const hasTaskDoc = plan.documents.some((d) => d.name === "task");
+  if (!hasTaskDoc) {
+    throw new ConfigError('tracked 开启时 plan.documents 必须包含 name 为 "task" 的文档');
+  }
+}
+```
+
+- [ ] **Step 5: 运行测试确认通过**
+
+Run: `bun test tests/core/config.test.ts`
+Expected: ALL PASS
+
+- [ ] **Step 6: 提交**
+
+```bash
+git add src/types.ts src/core/config.ts tests/core/config.test.ts
+git commit -m "feat: metadata.tracked 类型与 validateConfig 校验"
+```

+
+### Task 2: validateTaskFormat 函数
+
+**Files:**
+
+- Modify: `src/core/task-parser.ts`
+- Test: `tests/core/task-parser.test.ts`
+
+- [ ] **Step 1: 写失败测试**
+
+在 `tests/core/task-parser.test.ts` 追加新的 describe 块：
+
+```typescript
+import { validateTaskFormat } from "../../src/core/task-parser.ts";
+
+describe("validateTaskFormat", () => {
+  it("合法 task 内容通过校验", () => {
+    expect(() => validateTaskFormat("- [x] 已完成\n- [ ] 未完成")).not.toThrow();
+  });
+
+  it("无 checkbox 项时抛错", () => {
+    expect(() => validateTaskFormat("# 标题\n一些描述")).toThrow();
+  });
+
+  it("空内容抛错", () => {
+    expect(() => validateTaskFormat("")).toThrow();
+  });
+
+  it("checkbox 文本为空时抛错", () => {
+    expect(() => validateTaskFormat("- [ ] \n- [x] 有内容")).toThrow();
+  });
+
+  it("checkbox 文本仅空格时抛错", () => {
+    expect(() => validateTaskFormat("- [ ]   ")).toThrow();
+  });
+
+  it("有 checkbox 且文本非空时通过", () => {
+    expect(() => validateTaskFormat("- [ ] 实现功能A")).not.toThrow();
+  });
+});
+```
+
+- [ ] **Step 2: 运行测试确认失败**
+
+Run: `bun test tests/core/task-parser.test.ts`
+Expected: 新增 validateTaskFormat 测试 FAIL（函数不存在）
+
+- [ ] **Step 3: 实现 validateTaskFormat**
+
+在 `src/core/task-parser.ts` 追加：
+
+```typescript
+export class TaskFormatError extends Error {
+  constructor(message: string) {
+    super(message);
+    this.name = this.constructor.name;
+  }
+}
+
+export function validateTaskFormat(content: string): void {
+  const tasks = parseTasks(content);
+  if (tasks.length === 0) {
+    throw new TaskFormatError("task.md 必须包含至少一个 checkbox 项");
+  }
+  for (const task of tasks) {
+    if (task.text.trim() === "") {
+      throw new TaskFormatError("task.md 中每个 checkbox 项必须有非空描述");
+    }
+  }
+}
+```
+
+- [ ] **Step 4: 运行测试确认通过**
+
+Run: `bun test tests/core/task-parser.test.ts`
+Expected: ALL PASS
+
+- [ ] **Step 5: 提交**
+
+```bash
+git add src/core/task-parser.ts tests/core/task-parser.test.ts
+git commit -m "feat: 新增 validateTaskFormat 校验函数"

+
+### Task 3: 默认配置新增 metadata.tracked
+
+**Files:**
+
+- Modify: `src/defaults/config.ts:3`
+- Test: `tests/defaults/config.test.ts`
+
+- [ ] **Step 1: 写失败测试**
+
+在 `tests/defaults/config.test.ts` 的 `defaultConfig` describe 块内追加：
+
+```typescript
+it("默认 metadata.tracked 为 true", () => {
+  expect(defaultConfig.metadata).toBeDefined();
+  expect(defaultConfig.metadata!.tracked).toBe(true);
+});
+```
+
+- [ ] **Step 2: 运行测试确认失败**
+
+Run: `bun test tests/defaults/config.test.ts`
+Expected: "默认 metadata.tracked 为 true" FAIL
+
+- [ ] **Step 3: 修改默认配置**
+
+在 `src/defaults/config.ts` 中，将 `defaultConfig` 增加 `metadata` 字段：
+
+```typescript
+export const defaultConfig: RuneConfig = {
+  metadata: {
+    tracked: true,
+  },
+  stages: {
+```
+
+- [ ] **Step 4: 运行测试确认通过**

+
+**Files:**
+
+- Modify: `src/core/assembler.ts:76-120`
+- Test: `tests/core/assembler.test.ts`
+
+- [ ] **Step 1: 写失败测试**
+
+在 `tests/core/assembler.test.ts` 的 `assembleBuildPrompt` describe 块内追加：
+
+```typescript
+it("tracked=false 时只输出通用提示词", async () => {
+  const config: RuneConfig = {
+    stages: { build: { prompt: "按规划文档逐步实现功能" } },
+    metadata: { tracked: false },

+
+- [ ] **Step 2: 运行测试确认失败**
+
+Run: `bun test tests/core/assembler.test.ts`
+Expected: 新增测试 FAIL（当前 assembleBuildPrompt 不检查 tracked，始终读 task.md）
+
+- [ ] **Step 3: 修改 assembleBuildPrompt**
+
+修改 `src/core/assembler.ts` 的 `assembleBuildPrompt` 函数：
+
+```typescript
+export async function assembleBuildPrompt(
+  config: RuneConfig,
