+## 本地部署指南
+
+
+### 环境要求
+- Python 3.10+
+- Node.js 18+
+- PostgreSQL 16+
+
+### 1. 安装数据库：PostgreSQL及pgvector插件（向量搜索)
+
+#### 方式一：Docker安装（推荐）
+使用 Docker + Docker Compose 部署 PostgreSQL 16 + pgvector 插件。
+
+**1. 创建docker-compose.yml文件**
+
+内容如下：
+
+```yaml
+version: '3.8'
+
+services:
+  db:
+    image: pgvector/pgvector:pg16
+    container_name: pgvector-db
+    environment:
+      POSTGRES_USER: myuser
+      POSTGRES_PASSWORD: your_password
+      POSTGRES_DB: mydb
+    ports:
+      - "5432:5432"
+    volumes:
+      - pgdata:/var/lib/postgresql/data
+    restart: unless-stopped
+
+volumes:
+  pgdata:
+```
+
+**说明：**
+- 使用 `pgvector/pgvector:pg16` 镜像，内置 PostgreSQL 16 + pgvector 插件
+- 数据保存在 Docker 卷 `pgdata` 中，重启不会丢失
+- 监听宿主机端口 5432，可用本地工具如 pgAdmin, DBeaver, psql 连接
+- 默认数据库名称：mydb
+- 默认用户名：myuser
+- 默认密码：your_password
+
+**2. 启动服务**
+
+在 `docker-compose.yml` 所在目录下运行：
+```bash
+docker-compose up -d
+```
+
+查看容器状态：
+```bash
+docker ps
+```
+
+输出应包含一个名为 `pgvector-db` 的容器，状态为 Up。
+
+**3. 验证 pgvector 安装成功**
+
+进入 PostgreSQL 容器：
+```bash
+docker exec -it pgvector-db psql -U myuser -d mydb
+```
+
+启用 pgvector 插件：
+```sql
+CREATE EXTENSION IF NOT EXISTS vector;
+```
+ 
+插入并查询向量数据（示例，可以在客户端，如dbeaver等）**
+
+```sql
+-- 创建表，包含一个向量字段（维度为3）
+CREATE TABLE items (
+  id SERIAL PRIMARY KEY,
+  embedding vector(3)
+);
+
+-- 插入向量数据
+INSERT INTO items (embedding) VALUES
+  ('[1,1,1]'),
+  ('[2,2,2]'),
+  ('[1,0,0]');
+
+-- 查询与 [1,1,1] 最接近的向量（基于欧几里得距离）
+SELECT id, embedding
+FROM items
+ORDER BY embedding <-> '[1,1,1]'
+LIMIT 3;
+```
+-- 上述没报错且有结果返回，即安装成功
+
+### 2. 后端部署
+```bash
+# 克隆项目
+git clone https://github.com/lkpAgent/chat-agent.git
+cd chat-agent/backend
+
+#创建python虚拟环境，推荐使用conda创建虚拟环境
+conda create -n chat-agent python=3.10
+conda activate chat-agent
+
+# 安装依赖
+pip install -r requirements.txt
+
+# 配置环境变量,windows下直接复制.env.example文件为.env  
+cp .env.example .env
+
+# 编辑.env文件，配置数据库连接和AI API密钥。相关配置信息见后面的配置说明
+
+# 配置完数据库信息后，初始化数据库表及创建登录账号(用户名: test@example.com, 密码: 123456)
+cd backend/tests
+python init_db.py
+
+# 启动后端服务，默认8000端口
+python -m uvicorn th_agenter.main:app --reload --host 0.0.0.0 --port 8000
+# 或者直接运行main.py
+# cd backend/th_agenter
+# python main.py
+
+```
+
+
+### 3. 前端部署
+```bash
+# 进入前端目录
+cd ../frontend
+
+# 安装依赖
+npm install
+
+# 配置环境变量
+cp .env.example .env
+# 编辑.env文件，配置后端API地址
+VITE_API_BASE_URL = http://localhost:8000
+
+# 开发环境，启动前端服务，默认端口3000
+npm run dev
+# 发布到生产环境，比如部署在{nginx_home}/html/yourdomain，则指定base路径编译
+# npm run build -- --base=yourdomain
+```
+启动成功后，访问http://localhost:3000，会进入到登录页面，默认账号密码为test@example.com/123456

+## ✨ 核心能力
+
+
+
+### 🤖 智能问答
+
+
+- **多模型支持**：集成DeepSeek、智谱AI、豆包等国内主流AI服务商
+- **三种对话模式**：
+  - 自由对话：直接与AI模型交互
+  - RAG对话：基于知识库的检索增强生成
+  - 智能体对话：多智能体协作处理复杂任务
+- **多轮对话**：支持连续对话，上下文理解和记忆

+
+## 🌟 技术特色
+
+### 基于LangGraph的智能体对话系统
+- **自主规划能力**：智能体能够根据任务需求自主调用工具并规划执行流程
+- **动态工具调用**：根据上下文自动选择最合适的工具并执行
+- **多步任务分解**：复杂任务自动拆解为多个子任务并顺序执行
+
+**示例场景**：  
+当用户询问"推荐长沙和北京哪个适宜旅游"时：
+1. 智能体首先调用搜索工具查找相关信息
+2. 未找到合适结果时，自动规划调用天气查询工具
+3. 智能拆分为两次执行：先查询长沙天气，再查询北京天气
+4. 根据气温数据判断北京更适宜旅游
+5. 自动调用搜索工具查找北京景点信息
+6. 最终整合所有信息生成总结推荐
+
+第一步：调用搜索引擎搜索哪个城市更适宜旅游 
+![智能体问答界面](docs/images/agent1.png)
+
+第二步：搜索的内容没有找到合适的答案，意识到错了后，改变策划，重新调用天气工具，从天气的角度判断哪个城市更适合当下旅游 。
+并且自动进行任务拆解，对北京、长沙分别调用一次天气工具，获取到两个城市的天气情况。
+
+![智能体问答界面](docs/images/agent2.png) 
+
+第三步：根据天气判断北京更适合旅游，再调用搜索引擎工具，搜索北京的特色景点。最后将工具调用结果与问题进行总结，完成本次对话过程。

+            # 任务说明
+            请分析文档内容，识别出适合作为分割点的关键位置。分割点应该是能够将文档划分为有意义段落的文本片段。
+
+            
+            # 分割规则
+            请严格按照以下规则识别分割点：
+
+            ## 基本要求
+            1. 分割点必须是完整的句子开头或段落开头
+            2. 每个分割后的部分应包含相对完整的语义内容
+            3. 每个分割部分的理想长度控制在500字以内，严禁超过1000字。如果超过了1000字，要强制分段。
+
+            ## 短段落处理
+            4. 如果某部分长度可能小于50字，应将其与后续内容合并，避免产生过短片段
+
+            ## 唯一性保证（重要）
+            5. 确保每个分割点在文档中具有唯一性：
+               - 检查文内是否存在相同的文本片段
+               - 如果存在重复，需要扩展分割点字符串，直到获得唯一标识
+               - 扩展方法：在当前分割点后追加几个字符，形成更长的唯一字符串
+
+            ## 示例说明
+            原始文档：
+            "目录：
+            第一章 标题一
+            第二章 标题二
+            正文
+            第一章 标题一
+            这是第一章的内容
+
+            第二章 标题二

+
+            错误分割点："第一章 标题一"（在目录和正文中重复出现）
+
+            正确分割点："第一章 标题一\n这是第"（通过追加内容确保唯一性）

+            - 只返回分割点文本字符串
+            - 每个分割点用~~分隔

+                    请根据用户提出的问题，结合给出的数据集的详细信息，直接编写Python相关代码来计算pandas中的值。要求：
+                    1. 只返回代码，不返回其他内容
+                    2. 只允许使用pandas和内置库
+                    3. 确保代码能够直接执行并返回结果，包括import必要的内置库
+                    4. 返回的结果应该是详细的、完整的数据，而不仅仅是简单答案 
+                    5. 结果应该包含足够的上下文信息，让用户能够验证和理解答案 
+                    6. 优先返回DataFrame格式的结果，便于展示为表格 
+                    7. 务必不要再去写代码查看数据集的结构，提示词里已经给出了每个数据集的结构信息，直接根据提示词里的结构信息进行判断。
+                    8. 要求代码中最后一次print的结果，必需是最后的正确结果（用户所需要的数据）
+

+                    - 如果问"销售额最高的产品"，要返回产品名称、销售额、销售数量、市场占比等完整信息（如果表格有该这些字段信息）
