+
+## 🎯 我需要...
+
+### 💬 AI 对话功能
+
+**前端：**
+```tsx
+import { AIStreamChat } from '@/shared/components/Chat';
+<AIStreamChat apiEndpoint="/api/v1/xxx/chat/stream" enableDeepThinking={true} />
+```
+
+**后端：**
+```typescript
+import { createStreamingService } from '../../../common/streaming';
+const service = createStreamingService(reply);
+await service.streamGenerate(messages);
+```
+
+📚 [详细文档](./00-通用能力层清单.md#2-chat-通用组件)
+
+---
+
+### 🤖 调用 LLM
+
+```typescript
+import { LLMFactory } from '../../../common/llm/adapters/LLMFactory';
+
+const llm = LLMFactory.getAdapter('deepseek-v3');
+const response = await llm.chat(messages);
+
+// 流式
+for await (const chunk of llm.chatStream(messages)) {
+  console.log(chunk.content);
+}
+```
+
+📚 [详细文档](./01-LLM大模型网关/)
+
+---
+
+### 📁 文件存储
+
+```typescript
+import { storage } from '../../../common/storage';
+
+// 上传
+const url = await storage.upload('path/file.pdf', buffer);
+
+// 下载
+const buffer = await storage.download('path/file.pdf');
+```
+
+📚 [详细文档](./00-通用能力层清单.md#4-存储服务)
+
+---
+
+### ⚡ 异步任务
+
+```typescript
+import { JobFactory } from '../../../common/jobs';
+
+const queue = JobFactory.getQueue();
+
+// 创建任务
+await queue.createJob('job-name', { taskId: 'xxx' });
+
+// 注册Worker
+queue.registerWorker('job-name', async (job) => {
+  // 处理逻辑
+});
+```
+
+📚 [详细文档](./Postgres-Only异步任务处理指南.md)
+
+---
+
+### 📄 文档处理
+
+```typescript
+import { ExtractionClient } from '../../../common/document/ExtractionClient';
+
+const client = new ExtractionClient();
+const text = await client.extractText(buffer, 'pdf');
+```
+
+📚 [详细文档](./02-文档处理引擎/)
+
+---
+
+### 🔍 知识库检索（RAG）
+
+```typescript
+import { DifyClient } from '../../../common/rag/DifyClient';
+
+const dify = new DifyClient(apiKey, baseURL);
+const results = await dify.retrievalSearch(query, options);
+```
+
+📚 [详细文档](./03-RAG引擎/)
+
+---
+
+### 💾 缓存服务
+
+```typescript
+import { cache } from '../../../common/cache';
+
+await cache.set('key', value, 3600);  // TTL: 3600秒
+const value = await cache.get('key');
+await cache.delete('key');
+```
+
+📚 [详细文档](./00-通用能力层清单.md#6-缓存服务)
+
+---
+
+### 📝 日志记录
+
+```typescript
+import { logger } from '../../../common/logging';
+
+logger.info('[Module] 操作描述', { userId: 'xxx', detail: 'xxx' });
+logger.error('[Module] 错误', { error, stack: error.stack });
+```
+
+📚 [详细文档](./00-通用能力层清单.md#7-日志服务)
+
+---
+
+### 🔐 认证授权
+
+**后端：**
+```typescript
+import { authenticate, getUserId } from '../../../common/auth';
+
+// 路由
+fastify.get('/api', { preHandler: [authenticate] }, handler);
+
+// 控制器
+const userId = getUserId(request);
+```
+
+**前端：**
+```typescript
+import { getAccessToken } from '@/framework/auth/api';
+const token = getAccessToken();
+
+// 或使用 apiClient（自动携带token）
+import apiClient from '@/common/api/axios';
+await apiClient.get('/api/xxx');
+```
+
+📚 [详细文档](../04-开发规范/10-模块认证规范.md)
+
+---
+
+### 📋 Prompt 管理
+
+```typescript
+import { PromptService } from '../../../common/prompt/prompt.service';
+
+const promptService = new PromptService();
+const prompt = await promptService.getActivePrompt('template_code');
+const rendered = promptService.renderPrompt(template, variables);
+```
+
+📚 [详细文档](./00-通用能力层清单.md#11-prompt-管理系统)
+
+---
+
+## 🏗️ 架构原则
+
+### ✅ 正确做法
+
+```typescript
+// 1. 使用通用能力，不要重复造轮子
+import { createStreamingService } from '../../../common/streaming';
+
+// 2. 遵循云原生规范
+await storage.upload();  // 不要用 fs.writeFileSync()
+
+// 3. 使用结构化日志
+logger.info('[Module] 操作', { detail });  // 不要用 console.log()
+
+// 4. 统一认证
+fastify.get('/api', { preHandler: [authenticate] });
+
+// 5. 标准化API格式
+// OpenAI Compatible, not 自定义格式
+```
+
+### ❌ 错误做法
+
+```typescript
+// 1. 自己实现已有的能力
+reply.raw.write('data: ...');  // ❌ 应该用 StreamingService
+
+// 2. 直接操作本地文件
+fs.writeFileSync('/tmp/file');  // ❌ 应该用 storage
+
+// 3. 使用 console.log
+console.log('debug');  // ❌ 应该用 logger
+
+// 4. 硬编码用户ID
+const userId = 'test';  // ❌ 应该用 getUserId(request)
+
+// 5. 自定义格式
+{ type: 'delta', content: 'xxx' }  // ❌ 应该用 OpenAI Compatible
+```
