+## 🌟 平台能力使用规范（2025-11-16 新增）
+
+> **⭐ 重要提示**：平台已提供完整的基础设施服务  
+> **详细规范**：[云原生开发规范](./08-云原生开发规范.md)  
+> **详细文档**：[平台基础设施规划](../09-架构实施/04-平台基础设施规划.md)
+
+### 必须复用的平台服务
+
+**业务模块（ASL/AIA/PKB/DC等）禁止重复实现以下功能：**
+
+| 服务 | 导入方式 | 用途 |
+|------|---------|------|
+| **存储服务** | `import { storage } from '@/common/storage'` | 文件上传下载 |
+| **日志系统** | `import { logger } from '@/common/logging'` | 标准化日志 |
+| **异步任务** | `import { jobQueue } from '@/common/jobs'` | 长时间任务 |
+| **缓存服务** | `import { cache } from '@/common/cache'` | 分布式缓存 |
+| **数据库** | `import { prisma } from '@/config/database'` | 数据库操作 |
+| **LLM能力** | `import { LLMFactory } from '@/common/llm'` | LLM调用 |
+
+---
+
+### ✅ 正确示例：使用平台服务
+
+```typescript
+// backend/src/modules/asl/services/literatureService.ts
+import { storage } from '@/common/storage'
+import { logger } from '@/common/logging'
+import { jobQueue } from '@/common/jobs'
+import { cache } from '@/common/cache'
+import { prisma } from '@/config/database'
+
+export class LiteratureService {
+  async uploadPDF(projectId: string, pdfBuffer: Buffer) {
+    // 1. 使用平台存储服务
+    const key = `asl/projects/${projectId}/pdfs/${Date.now()}.pdf`
+    const url = await storage.upload(key, pdfBuffer)
+    
+    // 2. 使用平台日志系统
+    logger.info('PDF uploaded', { projectId, url })
+    
+    // 3. 使用平台数据库
+    const literature = await prisma.aslLiterature.create({
+      data: { projectId, pdfUrl: url, pdfFileSize: pdfBuffer.length }
+    })
+    
+    // 4. 使用平台缓存
+    await cache.set(`literature:${literature.id}`, literature, 3600)
+    
+    return literature
+  }
+  
+  async startScreening(projectId: string, literatureIds: string[]) {
+    // 5. 使用平台异步任务（长时间任务必须异步）
+    const job = await jobQueue.push('asl:screening', {
+      projectId,
+      literatureIds
+    })
+    
+    logger.info('Screening job created', { jobId: job.id })
+    return { jobId: job.id }  // 立即返回
+  }
+}
+```
+
+---
+
+### ❌ 错误示例：重复实现平台能力
+
+```typescript
+// ❌ 错误：在业务模块中自己实现存储
+// backend/src/modules/asl/storage/LocalStorage.ts  ← 不应该存在！
+import fs from 'fs'
+
+export class LocalStorage {
+  async upload(file: Buffer) {
+    await fs.writeFile('./uploads/file.pdf', file)  // ❌ 重复实现
+    return '/uploads/file.pdf'
+  }
+}
+
+// ❌ 错误：在业务模块中自己实现日志
+// backend/src/modules/asl/logger/logger.ts  ← 不应该存在！
+import winston from 'winston'
+
+export const logger = winston.createLogger({...})  // ❌ 重复实现
+
+// ❌ 错误：每次新建数据库连接
+import { PrismaClient } from '@prisma/client'
+
+export function getUser() {
+  const prisma = new PrismaClient()  // ❌ 连接泄漏
+  return prisma.user.findMany()
+}
+```
+
+**为什么错误？**
+- ❌ 重复代码，难以维护
+- ❌ 不同模块实现不一致
+- ❌ 无法统一切换环境（本地/云端）
+- ❌ 浪费开发时间
+- ❌ 云端部署会失败（Serverless限制）
+
+---
+
+### 文件上传规范
+
+```typescript
+// ✅ 正确：使用存储抽象层
+const url = await storage.upload('asl/pdf/123.pdf', buffer)
+
+// ❌ 错误：直接操作文件系统
+fs.writeFileSync('./uploads/123.pdf', buffer)  // Serverless容器重启会丢失
+
+// ❌ 错误：硬编码存储路径
+const filePath = 'D:/uploads/123.pdf'  // Windows路径，Linux无法运行
+```
+
+---
+
+### 异步任务规范
+
+```typescript
+// ✅ 正确：长时间任务（>10秒）必须异步处理
+app.post('/screening/start', async (req, res) => {
+  const job = await jobQueue.push('asl:screening', data)
+  res.send({ jobId: job.id })  // 立即返回，不等待完成
+})
+
+// 查询进度
+app.get('/screening/jobs/:id', async (req, res) => {
+  const job = await jobQueue.getJob(req.params.id)
+  res.send({ status: job.status, progress: job.progress })
+})
+
+// ❌ 错误：同步等待长时间任务
+app.post('/screening/start', async (req, res) => {
+  const results = await processAllLiteratures(data)  // 可能需要10分钟
+  res.send({ results })  // Serverless 30秒超时！
+})
+```
+
+---
+
+### 数据库连接规范
+
+```typescript
+// ✅ 正确：使用全局Prisma实例
+import { prisma } from '@/config/database'
+
+export async function getUsers() {
+  return await prisma.user.findMany()
+}
+
+// ❌ 错误：每次新建实例
+export async function getUsers() {
+  const prisma = new PrismaClient()  // 连接数耗尽！
+  return await prisma.user.findMany()
+}
+```
+
+---
+
+### 日志规范
+
+```typescript
+// ✅ 正确：使用平台日志系统
+import { logger } from '@/common/logging'
+
+logger.info('Operation successful', { userId, action: 'upload' })
+logger.error('Operation failed', { error: err.message, userId })
+
+// ❌ 错误：使用console.log
+console.log('Operation successful')  // 无法集中收集，难以查询
+
+// ❌ 错误：写本地日志文件
+fs.appendFileSync('./app.log', 'Operation successful')  // Serverless不支持
+```
+
+---
