# DevTask 模块实施计划

> **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:** 实现开发任务（DevTask）模块 V1，包含数据模型、Store、任务列表、详情、工时记录与"与我相关"聚合接入。

**Architecture:** 前端纯 localStorage Mock，遵循已有模块结构。三个 Store（DevTask / TaskWorklog / TaskCategory）+ 库函数 + 版本详情页内嵌 Tab + 工作台聚合扩展。

**Tech Stack:** Next.js 14 App Router + TypeScript + Zustand + Tailwind + Shadcn/ui + lucide-react

**Spec 文档:** `docs/specs/2026-06-11-dev-task-module-design.md`

## Task 13: 版本详情页接入 DevTaskTab

**Files:**
- Modify: `apps/web/app/versions/[id]/page.tsx`

- [ ] **Step 1: 在版本详情页导入 DevTaskTab 并接入 "开发任务" Tab**

在文件顶部增加导入：

```tsx
import { DevTaskTab } from '@/components/dev-task/DevTaskTab';
```

在 Tab 内容渲染区域，找到 `activeTab === 'tasks'` 对应的占位区域（当前显示"功能开发中，敬请期待"），替换为：

```tsx
{activeTab === 'tasks' && (
  <DevTaskTab
    versionId={versionId}
    requirementIds={versionReqs.map((r) => r.id)}
  />
)}
```

其中 `versionReqs` 是该版本已关联的需求列表（已在页面中通过 `requirements.filter(r => r.versionId === versionId)` 获取）。

- [ ] **Step 2: 在浏览器中验证**

Run: `pnpm dev --filter=web`

打开 http://localhost:3000/versions/{任意版本id}，切换到"开发任务" Tab：
- 应看到空状态 + "创建第一个任务"按钮
- 点击新建，填写表单创建任务
- 创建后列表出现，点击行展开详情抽屉
- 测试登记工时、标记阻塞、状态流转

- [ ] **Step 3: Commit**

```bash
git add apps/web/app/versions/[id]/page.tsx
git commit -m "feat(dev-task): 版本详情页接入开发任务 Tab"
```

---

## Task 14: "与我相关"工作台扩展

**Files:**
- Modify: `apps/web/app/workspace/page.tsx`

- [ ] **Step 1: 扩展工作台支持 DevTask 实体**

在 workspace/page.tsx 中：

1. 导入新依赖：

```tsx
import { useDevTaskStore } from '@/stores/useDevTaskStore';
import { useTaskCategoryStore } from '@/stores/useTaskCategoryStore';
import { DEV_TASK_STATUS_LABEL } from '@/lib/dev-task';
import { StatusBadge } from '@/components/dev-task/StatusBadge';
```

2. 扩展 TabKey 类型和 TABS 数组，增加 `'devTask'` 分组：

```tsx
type TabKey = 'all' | 'research' | 'product' | 'ui' | 'devTask';

// 在 TABS 数组末尾追加：
{ key: 'devTask', label: '开发任务', icon: Code2 },
```

3. 在组件内获取 DevTask 数据：

```tsx
const { tasks: devTasks, fetchTasks } = useDevTaskStore();
const { categories, fetchCategories } = useTaskCategoryStore();

useEffect(() => { fetchTasks(); }, [fetchTasks]);
useEffect(() => { fetchCategories(); }, [fetchCategories]);
```

4. 筛选"我的开发任务"：

```tsx
const myDevTasks = useMemo(
  () => devTasks.filter((t) => t.assigneeId === userName && t.status !== 'done'),
  [devTasks, userName],
);
```

5. 更新 counts 对象增加 devTask 计数：

```tsx
devTask: myDevTasks.length,
```

6. 更新 all 计数为 `myPlans.length + myDevTasks.length`

7. 在 filtered 渲染区域，当 `activeTab === 'devTask'` 时渲染开发任务卡片（复用 DevTaskRow 或简化展示）。

- [ ] **Step 2: 在浏览器验证**

打开 http://localhost:3000/workspace：
- 左侧导航出现"开发任务"分组
- 计数正确
- 点击后右侧展示我负责的未完成开发任务

- [ ] **Step 3: Commit**

```bash
git add apps/web/app/workspace/page.tsx
git commit -m "feat(dev-task): 与我相关工作台接入开发任务聚合"
```

## Task 15: 任务类型管理页

**Files:**
- Create: `apps/web/app/admin/categories/page.tsx`

- [ ] **Step 1: 创建 admin/categories/page.tsx**

管理页面：展示所有任务类型列表（按 group 分组），支持新增/编辑名称/删除（系统预置项不可删除）。

```tsx
'use client';

import { useState, useEffect } from 'react';
import { Plus, Pencil, Trash2, Shield } from 'lucide-react';
import { useTaskCategoryStore } from '@/stores/useTaskCategoryStore';
import { CATEGORY_GROUP_LABEL } from '@/lib/task-category';
import type { CategoryGroup } from '@/lib/task-category';

export default function CategoriesPage() {
  const { categories, fetchCategories, addCategory, updateCategory, deleteCategory } = useTaskCategoryStore();
  useEffect(() => { fetchCategories(); }, [fetchCategories]);

  const [newName, setNewName] = useState('');
  const [newGroup, setNewGroup] = useState<CategoryGroup>('development');
  const [editingId, setEditingId] = useState<string | null>(null);
  const [editName, setEditName] = useState('');

  const groups: CategoryGroup[] = ['development', 'testing', 'implementation', 'other'];

  const handleAdd = () => {
    if (!newName.trim()) return;
    addCategory(newName.trim(), newGroup);
    setNewName('');
  };

  const handleSaveEdit = (id: string) => {
    if (editName.trim()) updateCategory(id, { name: editName.trim() });
    setEditingId(null);
  };

  return (
    <div className="p-6 max-w-2xl mx-auto space-y-6">
      <h1 className="text-[16px] font-semibold text-[var(--ink)]">任务类型管理</h1>

      {/* 新增 */}
      <div className="flex gap-2">
        <input value={newName} onChange={(e) => setNewName(e.target.value)} onKeyDown={(e) => { if (e.key === 'Enter') handleAdd(); }} placeholder="新类型名称" className="flex-1 h-9 rounded-lg border border-[var(--line)] px-3 text-[13px] focus:border-[var(--accent)] focus:outline-none" />
        <select value={newGroup} onChange={(e) => setNewGroup(e.target.value as CategoryGroup)} className="h-9 rounded-lg border border-[var(--line)] px-3 text-[13px]">
          {groups.map((g) => <option key={g} value={g}>{CATEGORY_GROUP_LABEL[g]}</option>)}
        </select>
        <button onClick={handleAdd} className="h-9 px-4 rounded-lg text-[12px] font-medium bg-[var(--accent)] text-white hover:bg-[var(--accent-hover)]"><Plus className="h-3.5 w-3.5 inline" /> 添加</button>
      </div>

      {/* 分组列表 */}
      {groups.map((g) => {
        const items = categories.filter((c) => c.group === g);
        if (items.length === 0) return null;
        return (
          <div key={g}>
            <h2 className="text-[13px] font-medium text-[var(--ink-soft)] mb-2">{CATEGORY_GROUP_LABEL[g]}</h2>
            <div className="rounded-lg border border-[var(--line)] divide-y divide-[var(--line)]">
              {items.map((cat) => (
                <div key={cat.id} className="flex items-center gap-3 px-4 py-2.5">
                  {cat.color && <span className="h-3 w-3 rounded-full" style={{ backgroundColor: cat.color }} />}
                  {editingId === cat.id ? (
                    <input value={editName} onChange={(e) => setEditName(e.target.value)} onBlur={() => handleSaveEdit(cat.id)} onKeyDown={(e) => { if (e.key === 'Enter') handleSaveEdit(cat.id); }} autoFocus className="flex-1 h-7 rounded border border-[var(--line)] px-2 text-[13px] focus:border-[var(--accent)] focus:outline-none" />
                  ) : (
                    <span className="flex-1 text-[13px] text-[var(--ink)]">{cat.name}</span>
                  )}
                  {cat.isSystem && <Shield className="h-3 w-3 text-[var(--ink-muted)]" title="系统预置" />}
                  {!cat.isSystem && (
                    <>
                      <button onClick={() => { setEditingId(cat.id); setEditName(cat.name); }} className="p-1 rounded hover:bg-[var(--bg-subtle)]"><Pencil className="h-3 w-3 text-[var(--ink-muted)]" /></button>
                      <button onClick={() => deleteCategory(cat.id)} className="p-1 rounded hover:bg-red-50"><Trash2 className="h-3 w-3 text-[var(--ink-muted)] hover:text-red-500" /></button>
                    </>
                  )}
                </div>
              ))}
            </div>
          </div>
        );
      })}
    </div>
  );
}
```

- [ ] **Step 2: 验证页面加载正常**

打开 http://localhost:3000/admin/categories，确认：
- 分组显示正确
- 系统预置项有盾牌图标，无删除按钮
- 可新增自定义类型
- 可编辑/删除自定义类型

- [ ] **Step 3: Commit**

```bash
git add apps/web/app/admin/categories/page.tsx
git commit -m "feat(dev-task): 添加任务类型管理页面"
```

## Task 16: 最终验证 & 收尾

- [ ] **Step 1: 完整流程验证**

在浏览器中走完整流程：

1. 打开版本详情页 → "开发任务" Tab → 新建任务（填写所有字段）
2. 创建多个任务（不同需求、不同类型、不同负责人）
3. 打开详情抽屉 → 流转状态（todo → in_progress → testing → submitted → done）
4. 测试回退（testing → in_progress）
5. 标记阻塞 → 解除阻塞
6. 登记工时 → 确认 actualHours 累加正确
7. 验证进度条随状态变化
8. 打开"与我相关" → 确认开发任务出现在个人工作台
9. 打开"任务类型管理" → 新增/编辑/删除自定义类型
10. 刷新页面，确认 localStorage 持久化正常

- [ ] **Step 2: Commit all remaining changes**

```bash
git add -A
git commit -m "feat(dev-task): 开发任务模块 V1 完成（类型库+Store+UI+工作台聚合）"
```
