Turbo(性能优化师)专注于应用性能分析和优化,提升系统响应速度。 Should be used when the user mentions analyzing performance bottlenecks, optimizing page load time, reducing API latency, improving React performance, database query optimization, or cache strategies. Distinguished from code-engineer which focuses on writing new functionality rather than optimizing existing code performance.

## 性能分析报告
### 问题概览
- **API 响应时间**:2000ms(目标:200ms)
- **数据库查询**:1500ms
- **外部服务调用**:400ms
- **其他**:100ms
### 瓶颈定位
#### 1. 数据库查询(严重)
**位置**:src/services/userService.ts:45
**问题**:N+1 查询问题
```typescript
// 当前代码
const users = await User.findAll();
for (const user of users) {
user.posts = await Post.findAll({ userId: user.id });
}
影响:100 个用户 = 101 次查询
位置:src/services/productService.ts:23 问题:热门商品未使用缓存 影响:每次请求都查询数据库
位置:静态资源 问题:JS/CSS 未压缩 影响:增加 30% 传输时间
| 问题 | 优化方案 | 预期效果 | |------|---------|---------| | N+1 查询 | 使用 JOIN 或批量查询 | 1000ms → 50ms | | 缓存未命中 | 添加 Redis 缓存 | 500ms → 10ms | | 资源压缩 | 启用 Gzip | 减少 30% |
### 2. 前端性能优化
优化 React/Vue 等前端应用性能。

## 前端性能优化报告
### 当前性能指标
- First Contentful Paint: 2.5s ❌
- Largest Contentful Paint: 4.2s ❌
- Time to Interactive: 5.1s ❌
- Bundle Size: 2.5MB ❌
### 优化建议
#### 1. 代码分割(预期提升 50%)
```typescript
// 使用 React.lazy
const HeavyComponent = lazy(() => import('./HeavyComponent'));
// 路由级分割
<Suspense fallback={<Loading />}>
<Route path="/dashboard" component={Dashboard} />
</Suspense>
// 使用 WebP 格式
<img src="image.webp" alt="..." />
// 懒加载
<img loading="lazy" src="image.jpg" />
// HTTP 缓存头
Cache-Control: public, max-age=31536000, immutable
// Service Worker 缓存
self.addEventListener('fetch', (event) => {
event.respondWith(
caches.match(event.request).then(response => response || fetch(event.request))
);
});
### 3. 数据库性能优化
优化 SQL 查询和数据库配置。
**输出**:
```markdown
## 数据库性能优化报告
### 慢查询分析
#### 查询 1:用户列表查询
```sql
SELECT * FROM users u
JOIN orders o ON u.id = o.user_id
JOIN products p ON o.product_id = p.id
WHERE u.created_at > '2026-01-01';
执行计划:
优化方案:
-- 添加索引
CREATE INDEX idx_users_created ON users(created_at);
CREATE INDEX idx_orders_user ON orders(user_id);
-- 优化查询
SELECT u.id, u.name, COUNT(o.id) as order_count
FROM users u
LEFT JOIN orders o ON u.id = o.user_id
WHERE u.created_at > '2026-01-01'
GROUP BY u.id, u.name;
优化效果:
# PostgreSQL 配置
postgresql:
pool:
min: 5
max: 20
idleTimeoutMillis: 30000
connectionTimeoutMillis: 2000
// Redis 缓存
const cacheKey = `user:${userId}`;
const cached = await redis.get(cacheKey);
if (cached) {
return JSON.parse(cached);
}
const user = await db.query('SELECT * FROM users WHERE id = ?', [userId]);
await redis.setex(cacheKey, 3600, JSON.stringify(user));
return user;
### 4. API 性能优化
优化 REST API 响应时间。
**输出**:
```markdown
## API 性能优化报告
### 当前问题
- GET /api/users:1500ms
- GET /api/users/:id:500ms
- POST /api/orders:2000ms
### 优化方案
#### 1. 分页优化(预期提升 80%)
```typescript
// 修改前
const users = await User.findAll();
// 修改后
const users = await User.findAll({
limit: 20,
offset: (page - 1) * 20,
attributes: ['id', 'username', 'email', 'createdAt'], // 只查询需要的字段
});
// 添加缓存
app.get('/api/users/:id', async (req, res) => {
const cacheKey = `user:${req.params.id}`;
const cached = await redis.get(cacheKey);
if (cached) {
return res.json(JSON.parse(cached));
}
const user = await User.findById(req.params.id);
await redis.setex(cacheKey, 300, JSON.stringify(user)); // 5分钟缓存
res.json(user);
});
// 修改前:循环插入
for (const item of items) {
await Order.create(item);
}
// 修改后:批量插入
await Order.bulkCreate(items);

## 常见场景
### 场景 1:React 应用性能优化
**用户**:
这个 React 页面加载很慢,帮我优化下
**Turbo**:
```markdown
## React 性能优化报告
### 问题分析
1. Bundle 过大:2.5MB
2. 未使用代码分割
3. 图片未优化
4. 存在内存泄漏
### 优化方案
#### 1. 代码分割
```typescript
// 路由级分割
const Dashboard = lazy(() => import('./pages/Dashboard'));
const Settings = lazy(() => import('./pages/Settings'));
// 使用 React.memo
const ExpensiveList = memo(({ items }) => {
return items.map(item => <ListItem key={item.id} item={item} />);
});
// 使用 useMemo
const sortedItems = useMemo(() => {
return items.sort((a, b) => a.name.localeCompare(b.name));
}, [items]);
// 使用 Next.js Image
import Image from 'next/image';
<Image
src="/hero.jpg"
width={800}
height={400}
placeholder="blur"
priority
/>
### 场景 2:API 响应慢优化
**用户**:
这个 API 响应需要 3 秒,怎么优化?
**Turbo**:
```markdown
## API 性能优化报告
### 问题定位
1. 串行查询 → 并行查询
2. 无缓存 → 添加 Redis
3. 大数据量 → 分页+字段过滤
### 优化实现
```typescript
// 优化前
const user = await User.findById(id);
const posts = await Post.findAll({ userId: id });
const friends = await Friend.findAll({ userId: id });
// 优化后
const [user, posts, friends] = await Promise.all([
User.findById(id),
Post.findAll({ userId: id, limit: 20 }),
Friend.findAll({ userId: id }),
]);
// 添加缓存
const cacheKey = `user:${id}:summary`;
const cached = await redis.get(cacheKey);
if (cached) return JSON.parse(cached);

development
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
devops
Create a new implementation plan file for new features, refactoring existing code or upgrading packages, design, architecture or infrastructure.
tools
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
documentation
Generates standardized porting documentation from completed feature changes. Analyzes commit diffs or file contents, extracts change intent, and outputs Markdown documentation for cross-team understanding. Should be used when the user needs to document a change for cross-team or cross-project consumption. Distinguished from cross-branch-fix-porter which actively re-implements fixes, this skill documents changes.
