+# 数据库配置统一清理报告
+
+## 问题描述
+
+后端代码中存在多处硬编码的数据库配置，分散在不同的脚本文件中，导致：
+1. 配置不统一，维护困难
+2. 密码明文硬编码在代码中，存在安全隐患
+3. 切换环境时需要修改多个文件
+
+## 修复方案
+
+**统一使用 `configs/config.yaml` 配置文件**，所有脚本从配置文件读取数据库连接信息。
+
+## 修改文件清单
+
+### 1. scripts/reset_db.go ✅
+- **修改前**: 硬编码 `dsn := "host=10.10.0.102 port=5432 user=postgres password=T5sSfTZ6XYTD9bfC..."`
+- **修改后**: 使用 `config.LoadConfig("configs/config.yaml")` + `database.InitPostgres()`
+
+### 2. scripts/seed_data.go ✅
+- **修改前**: 硬编码 `connStr := "host=localhost port=5432 user=postgres password=123456..."`
+- **修改后**: 使用 `config.LoadConfig()` 并动态构建连接字符串
+
+### 3. scripts/init_db.go ✅
+- **修改前**: 两处硬编码（连接 postgres 数据库 + 连接目标数据库）
+- **修改后**: 统一使用配置文件，动态生成数据库名称
+
+### 4. scripts/check_users_table.go ✅
+- **修改前**: 硬编码连接字符串
+- **修改后**: 使用配置文件
+
+### 5. scripts/check_menus.go ✅
+- **修改前**: 硬编码连接字符串
+- **修改后**: 使用配置文件
+
+### 6. scripts/migrate_user_fields.go ✅
+- **修改前**: 硬编码连接字符串
+- **修改后**: 使用配置文件
+
+### 7. scripts/migrate.go ✅
+- **修改前**: 错误的 import 路径 (`internal/config`, `internal/database`)
+- **修改后**: 修正为 `pkg/config`, `pkg/database`，并使用配置文件
+
+### 8. testdata/import_medicines.go ✅
+- **修改前**: 硬编码 `dsn := "host=localhost user=postgres password=123456..."`
+- **修改后**: 使用 `config.LoadConfig()` + `database.InitPostgres()`
+
+## 配置文件结构
+
+所有脚本现在统一使用 `configs/config.yaml`：
+
+```yaml
+database:
+  host: 10.10.0.102
+  port: 5432
+  user: postgres
+  password: T5sSfTZ6XYTD9bfC
+  dbname: xxxx
+  sslmode: disable
+  schema: public
+  timezone: Asia/Shanghai
+```
+
+## 优势
+
+1. ✅ **单一配置源**: 所有数据库配置集中在 `config.yaml`
+2. ✅ **安全性提升**: `config.yaml` 已在 `.gitignore` 中，不会提交到版本控制
+3. ✅ **易于维护**: 切换环境只需修改一个配置文件
+4. ✅ **代码一致性**: 所有脚本使用相同的配置加载方式
+5. ✅ **编译验证**: 所有脚本编译通过
+
+## 验证
+
+```bash
+# 编译验证
+go build ./scripts/migrate.go  # ✅ 通过
+go build ./cmd/api/...         # ✅ 通过
+```
+
+## 注意事项
+
+- 确保 `configs/config.yaml` 文件存在且配置正确
+- 不要将 `config.yaml` 提交到版本控制（已在 `.gitignore` 中）
+- 使用 `config.example.yaml` 作为配置模板

+
+## 📝 最佳实践
+
+1. **拉取代码后**: 运行 `go run scripts/migrate_all.go` 同步表结构
+2. **修改模型后**: 运行 `go run scripts/migrate_all.go` 更新数据库
+3. **生产部署前**: 
+   - 备份数据库
+   - 在测试环境验证
+   - 低峰期执行
+
+## 🎯 优势总结
+
+### 之前的问题
+- ❌ 8 个脚本硬编码数据库配置
+- ❌ 多个不完整的迁移脚本
+- ❌ 缺少统一的迁移入口
+- ❌ 密码明文在代码中
+
+### 现在的优势
+- ✅ 单一配置源 (`config.yaml`)
+- ✅ 完整迁移脚本 (54张表)
+- ✅ 清晰的文档说明
+- ✅ 安全的配置管理
+- ✅ 易于维护和使用
+
+## 📌 注意事项
+
+1. **配置文件**: `configs/config.yaml` 不要提交到 Git
+2. **生产环境**: 迁移前务必备份数据库
+3. **外键约束**: 已禁用自动外键（应用层校验）
+4. **UUID字段**: 使用 `string` 类型，不是 `uint`
+5. **软删除**: 使用 `gorm.DeletedAt`

+
+## 使用方法
+
+### 1. 完整迁移（推荐）
+
+执行所有表的迁移：
+
+```bash
+cd server
+go run scripts/migrate_all.go
+```
+
+这将：
+- 自动创建所有不存在的表
+- 更新已存在表的结构（添加新字段、修改字段类型等）
+- **不会删除已存在的数据**
+
+### 2. 初始化数据库
+
+如果是全新数据库，需要先创建数据库：
+
+```bash
+go run scripts/init_db.go
+```
+
+然后执行迁移：
+
+```bash
+go run scripts/migrate_all.go
+```
+
+### 3. 重置数据库（危险操作）
+
+⚠️ **警告：此操作会删除所有数据！**
+
+```bash
+go run scripts/reset_db.go
+```
+
+### 4. 导入种子数据
+
+导入管理员和医生数据：
+
+```bash
+go run scripts/seed_data.go
+```
+
+## 配置要求
+
+所有脚本统一使用 `configs/config.yaml` 配置文件：
+
+```yaml
+database:
+  host: 10.10.0.102
+  port: 5432
+  user: postgres
+  password: your-password
+  dbname: internet_hospital
+  sslmode: disable
+  schema: public
+  timezone: Asia/Shanghai
+```
+
+## 迁移策略
+
+### GORM AutoMigrate 特性
+
+✅ **会做的事情：**
+- 创建不存在的表
+- 添加缺失的字段
+- 添加缺失的索引
+- 修改字段类型（某些情况）
+
+❌ **不会做的事情：**
+- 删除未使用的字段
+- 删除未使用的索引
+- 修改字段名称
+- 删除表
+
+### 手动迁移场景
+
+如果需要：
+1. 重命名字段
+2. 删除字段
+3. 复杂的数据转换
+
+请手动编写 SQL 迁移脚本。
+
+## 验证迁移
+
+迁移完成后，可以通过以下方式验证：
+
+```bash
+# 连接数据库
+psql -U postgres -d internet_hospital
+
+# 查看所有表
+\dt
+
+# 查看特定表结构
+\d users
+\d roles
+\d menus
+```
+
+## 常见问题
+
+### Q: 迁移失败怎么办？
+
+A: 检查错误信息，常见原因：
+- 数据库连接失败（检查 config.yaml）
+- 字段类型冲突（需要手动调整）
+- 外键约束冲突（检查数据一致性）
+
+### Q: 如何添加新表？
+
+A: 
+1. 在 `internal/model/` 下创建模型文件
+2. 在 `migrate_all.go` 的 `allModels` 列表中添加
+3. 运行 `go run scripts/migrate_all.go`
+
+### Q: 如何修改表结构？
+
+A:
+1. 修改 `internal/model/` 中的模型定义
+2. 运行 `go run scripts/migrate_all.go`
+3. GORM 会自动添加新字段
+
+## 脚本清单
+
+### 当前可用脚本
+
+- ✅ `migrate_all.go` - **完整迁移脚本（推荐使用）**
+- ✅ `init_db.go` - 初始化数据库
+- ✅ `reset_db.go` - 重置数据库（危险）
+- ✅ `seed_data.go` - 导入种子数据
+- ✅ `gen_hash.go` - 生成密码哈希
+
+### 已废弃脚本（已删除）
+
+- ❌ `migrate.go` - 不完整的迁移脚本
+- ❌ `migrate_user_fields.go` - 单表迁移脚本
+- ❌ `check_users_table.go` - 检查脚本
+- ❌ `check_menus.go` - 检查脚本
+
+## 最佳实践
+
+1. **开发环境**：直接使用 `migrate_all.go`
+2. **生产环境**：
+   - 先在测试环境验证
+   - 备份数据库
+   - 在低峰期执行
+   - 监控迁移过程
+
+3. **版本控制**：
+   - 模型定义纳入版本控制
+   - 复杂迁移编写 SQL 脚本并版本化
+
+4. **团队协作**：
+   - 拉取代码后运行 `migrate_all.go` 同步表结构
+   - 提交代码前确保模型定义正确
+
+## 注意事项
+
+⚠️ **重要提醒：**
+
+1. `config.yaml` 不要提交到版本控制（已在 .gitignore）
+2. 生产环境迁移前务必备份数据库
+3. 外键约束已禁用（`DisableForeignKeyConstraintWhenMigrating: true`）
+4. 所有 UUID 字段使用 `string` 类型，不是 `uint`
+5. 软删除字段使用 `gorm.DeletedAt`

server/scripts/README.md

-# 数据库初始化脚本
+# 数据库脚本说明
 
-## 初始化测试医生数据
+本目录包含数据库初始化、迁移和种子数据相关的脚本。
 
-在开发环境中，需要先创建测试医生数据才能正常使用问诊功能。
+## 📋 快速开始
 
-### 执行方式
+### 1. 完整迁移（推荐）
 
 ```bash
-# 方式1：使用psql命令行
-psql -U postgres -d internet_hospital -f scripts/seed_doctors.sql
+# 执行所有表的迁移
+go run scripts/migrate_all.go
+```
+
+### 2. 初始化新数据库
+
+```bash
+# 创建数据库
+go run scripts/init_db.go
+
+# 执行迁移
+go run scripts/migrate_all.go
+
+# 导入种子数据
+go run scripts/seed_data.go
+```
+
+## 🔧 脚本列表
+
+### 核心脚本
+
+#### migrate_all.go ⭐
+**完整数据库迁移脚本（推荐使用）**
+
+- 迁移所有 54 张表
+- 自动创建不存在的表
+- 更新已存在表的结构
+- 不会删除已存在的数据
+
+```bash
+go run scripts/migrate_all.go
+```
+
+#### init_db.go
+初始化数据库，创建 `internet_hospital` 数据库。
+
+```bash
+go run scripts/init_db.go
+```
+
+#### reset_db.go ⚠️
+**危险操作：重置数据库（删除所有数据）**
 
-# 方式2：使用数据库管理工具（如DBeaver、pgAdmin）
-# 直接打开 seed_doctors.sql 文件并执行
+```bash
+go run scripts/reset_db.go
+```
+
+#### seed_data.go
+导入种子数据（管理员用户和医生数据）。
+
+```bash
+go run scripts/seed_data.go
 ```
 
-### 测试账号
+#### gen_hash.go
+生成 bcrypt 密码哈希。
+
+```bash
+go run scripts/gen_hash.go
+```
+
+### SQL 脚本
+
+#### seed_admin.sql
+创建超级管理员账号：
+- 用户名: admin
+- 密码: admin123
+- 角色: admin
 
-执行脚本后会创建以下测试医生账号：
+#### seed_doctors.sql
+导入示例医生数据，包含多个科室的医生信息。
 
-| 手机号 | 密码 | 姓名 | 科室 | 职称 | 状态 |
-|--------|------|------|------|------|------|
-| 13800000001 | 123456 | 张医生 | 内科 | 主任医师 | 已认证 |

-### 问题排查
+包含：
+- 完整表结构清单
+- 迁移策略说明
+- 常见问题解答
+- 最佳实践建议
 
-如果创建问诊时报错 "违反外键约束 consultations_doctor_id_fkey"：
+## 注意事项
 
-1. 检查数据库中是否有医生记录：
-   ```sql
-   SELECT id, name, status FROM doctors WHERE status = 'approved';
-   ```
+1. ✅ 所有脚本已统一使用配置文件，无硬编码
+2. ⚠️ `config.yaml` 不要提交到版本控制
+3. 🔒 生产环境迁移前务必备份数据库
+4. 🚀 推荐使用 `migrate_all.go` 进行日常迁移
 
-2. 确认前端传递的 doctor_id 是否存在于 doctors 表中
+## 已废弃脚本（已删除）
 
-3. 重新执行 seed_doctors.sql 脚本
+以下脚本已被 `migrate_all.go` 替代：
+- ❌ `migrate.go` - 不完整的迁移脚本
+- ❌ `migrate_user_fields.go` - 单表迁移脚本
+- ❌ `check_users_table.go` - 检查脚本
+- ❌ `check_menus.go` - 检查脚本

+
+### 2.3 关键差距总结
+
+**internet-hospital 需要从 ai-pacs 学习的 6 大能力**：
+
+1. **SSE answer_chunk 真流式** — 当前后端 `emitChunks()` 是假流式（LLM完成后再模拟打字）
+2. **结构化工具结果渲染** — `ToolCallCard` + `ToolResultCard` 按工具类型定制UI
+3. **建议操作按钮系统** — `SuggestedAction`（navigate/chat/followup）让回复可交互
+4. **页面导航能力** — `navigate_page` 工具 + 前端事件总线实现AI驱动页面跳转
+5. **内嵌页面浏览** — 在对话窗口内iframe嵌入系统页面
+6. **Markdown增强** — 表格渲染、代码高亮、引号快捷发送

+└─────────────────────────────────────────────────────────────────┘
+```
+

+
+## 四、详细实施方案
+
+### Phase 1：AI智能助手 — 后端真流式改造（★★★★★）
+
+#### 1.1 问题分析
+
+当前 `react_agent.go` 的 `RunStream()` 方法在 LLM 返回完整文本后，通过 `emitChunks()` 模拟打字效果（每3个rune休眠15ms），用户感知到的延迟 = LLM思考时间 + 打字模拟时间。
+
+```go
+// 当前实现（伪流式）
+// react_agent.go:270-280
+if choice.FinishReason == "stop" || len(choice.Message.ToolCalls) == 0 {
+    emitChunks(ctx, choice.Message.Content, onEvent)  // ← 全文完成后才分块
+    return &AgentOutput{...}, nil
+}
+```
+
+#### 1.2 改造方案
+
+在 `pkg/ai/` 层新增 `ChatWithToolsStream()` 方法，返回 SSE token 流；在 `react_agent.go` 的最终文本阶段使用真流式输出。
+
+**新增文件** `server/pkg/ai/stream.go`：
+
+```go
+// StreamChatWithTools 流式调用LLM（支持tool_calls）
+// 返回 channel，每个 StreamDelta 包含：
+//   - Type: "content" / "tool_call" / "done"
+//   - Content: 文本片段
+//   - ToolCall: 工具调用增量
+type StreamDelta struct {
+    Type     string
+    Content  string
+    ToolCall *ToolCallDelta
+    Usage    *Usage
+}
+
+func (c *Client) ChatWithToolsStream(ctx context.Context, messages []ChatMessage, tools []interface{}) (<-chan StreamDelta, error) {
+    // 使用 OpenAI stream=true 参数
+    // 逐 token 推送 delta
+    // 在最后一个 delta 中附带 Usage
+}
+```
+
+**修改** `server/pkg/agent/react_agent.go` 的 `RunStream()`：
+
+```go
+// 改造后（真流式）
+// 最终文本阶段：
+if choice.FinishReason == "stop" || len(choice.Message.ToolCalls) == 0 {
+    // 使用真流式输出
+    ch, err := client.ChatWithToolsStream(ctx, messages, tools)
+    var fullText strings.Builder
+    for delta := range ch {
+        if delta.Type == "content" {
+            fullText.WriteString(delta.Content)
+            onEvent(StreamEvent{
+                Type: StreamEventChunk,
+                Data: map[string]interface{}{"content": delta.Content},
+            })
+        }
+    }
+    return &AgentOutput{Response: fullText.String(), ...}, nil
+}
+```
+
+**新增事件类型**：
+
+```go
+const (
+    StreamEventThinking   StreamEventType = "thinking"
+    StreamEventToolCall   StreamEventType = "tool_call"
+    StreamEventToolResult StreamEventType = "tool_result"
+    StreamEventChunk      StreamEventType = "chunk"       // 已有
+    StreamEventAnswerChunk StreamEventType = "answer_chunk" // 新增：与ai-pacs对齐
+)
+```
+
+---
+
+### Phase 2：AI智能助手 — 前端全面升级（★★★★★）
+
+#### 2.1 新增 ToolCallCard 组件
+
+参考 `ai-pacs/frontend/src/components/ai/ToolCallCard.tsx`，为互联网医院场景定制工具元数据。
+
+**新增文件** `web/src/components/GlobalAIFloat/ToolCallCard.tsx`：
+
+```tsx
+// 工具元数据映射（互联网医院场景）
+const TOOL_META: Record<string, { label: string; color: string; icon: string }> = {
+  query_drug:              { label: '药品查询',   color: 'green',  icon: 'MedicineBoxOutlined' },
+  query_medical_record:    { label: '病历查询',   color: 'blue',   icon: 'FileSearchOutlined' },
+  query_symptom_knowledge: { label: '症状知识',   color: 'purple', icon: 'BulbOutlined' },
+  recommend_department:    { label: '科室推荐',   color: 'cyan',   icon: 'ApartmentOutlined' },
+  check_drug_interaction:  { label: '药物相互作用', color: 'red',   icon: 'WarningOutlined' },
+  check_contraindication:  { label: '禁忌症检查', color: 'orange', icon: 'StopOutlined' },
+  calculate_dosage:        { label: '剂量计算',   color: 'gold',   icon: 'CalculatorOutlined' },
+  search_medical_knowledge:{ label: '知识检索',   color: 'geekblue', icon: 'BookOutlined' },
+  navigate_page:           { label: '页面导航',   color: 'blue',   icon: 'CompassOutlined' },
+  send_notification:       { label: '发送通知',   color: 'volcano', icon: 'BellOutlined' },
+  call_agent:              { label: '调用Agent',  color: 'purple', icon: 'RobotOutlined' },
+  trigger_workflow:        { label: '触发工作流', color: 'cyan',   icon: 'DeploymentUnitOutlined' },
+  eval_expression:         { label: '表达式计算', color: 'lime',   icon: 'CodeOutlined' },
+  write_knowledge:         { label: '知识写入',   color: 'green',  icon: 'EditOutlined' },
+};
+
+// 参数中文映射
+const PARAM_LABELS: Record<string, string> = {
+  drug_name: '药品名', patient_id: '患者ID', symptom: '症状',
+  department: '科室', dosage: '剂量', query: '查询内容',
+  drug_a: '药品A', drug_b: '药品B', keywords: '关键词',
+  collection_id: '知识库ID', expression: '表达式',
+  agent_id: 'AgentID', workflow_id: '工作流ID',
+  page: '页面', action: '操作', title: '标题', content: '内容',
+};
+
+interface ToolCallCardProps {
+  toolName: string;
+  toolInput?: Record<string, unknown>;
+  status?: 'running' | 'success' | 'error';
+}
+```
+
+核心交互：
+- 折叠/展开参数详情
+- 状态指示器（运行中旋转 / 成功绿勾 / 失败红叉）
+- 参数自动中文翻译
+- 摘要信息（折叠时显示关键参数）
+
+#### 2.2 新增 ToolResultCard 组件
+
+参考 `ai-pacs/frontend/src/components/ai/ToolResultCard.tsx`，按工具类型定制渲染。
+
+**新增文件** `web/src/components/GlobalAIFloat/ToolResultCard.tsx`：
+
+```tsx
+// 按工具类型渲染不同卡片：
+// query_drug          → 药品信息卡片（名称/规格/价格/库存）
+// query_medical_record → 病历摘要卡片（诊断/日期/医生）
+// recommend_department → 科室推荐卡片（科室名/匹配度/排班信息）
+// check_drug_interaction → 风险警告卡片（红色/橙色分级）
+// check_contraindication → 禁忌症警告卡片
+// calculate_dosage    → 剂量计算结果卡片
+// search_medical_knowledge → 知识条目列表卡片
+// navigate_page       → 导航成功卡片（含"在主页面打开"按钮）
+// eval_expression     → 计算结果卡片
+// 通用               → JSON折叠展示
+// 错误               → 红色错误卡片
+```
+
+#### 2.3 新增 SuggestedAction 建议操作按钮系统
+
+参考 ai-pacs 的 `ACTIONS` 标记机制，让 Agent 回复末尾可以携带可交互按钮。
+
+**后端改造** — Agent SystemPrompt 中注入 ACTIONS 格式说明：
+
+```go
+// 在 buildSystemPrompt() 中追加 ACTIONS 格式说明
+const actionsPromptSuffix = `
+
+## ACTIONS 按钮格式
+
+回复末尾使用 <!--ACTIONS:[...]-->  输出建议操作按钮。类型包括:
+- navigate: 跳转页面 {"type":"navigate","label":"查看处方","path":"/admin/prescription"}
+- chat: 继续对话 {"type":"chat","label":"查看更多","prompt":"请展示详细信息"}
+- followup: 追问 {"type":"followup","label":"换个科室","prompt":"推荐其他科室"}
+
+示例:
+<!--ACTIONS:[
+  {"type":"navigate","label":"查看处方详情","path":"/admin/prescription/123"},
+  {"type":"chat","label":"查看药品相互作用","prompt":"检查这些药物的相互作用"},
+  {"type":"followup","label":"调整用药方案","prompt":"请帮我调整用药方案"}
+]-->
+`
+```
+
+**前端解析** — 在 ChatPanel 中解析 ACTIONS 标记：
+
+```tsx
+// 解析 AI 回复中的 <!--ACTIONS:[...]-->
+function parseActions(content: string): { cleanContent: string; actions: SuggestedAction[] } {
+  const pattern = /<!--ACTIONS:\[([\s\S]*?)\]-->/;
+  const match = content.match(pattern);
+  if (!match) return { cleanContent: content, actions: [] };
+  try {
+    const actions = JSON.parse('[' + match[1] + ']');
+    const cleanContent = content.replace(pattern, '').trim();
+    return { cleanContent, actions };
+  } catch {
+    return { cleanContent: content, actions: [] };
+  }
+}
+```
+
+**SuggestedAction 类型定义**：
+
+```tsx
+export interface SuggestedAction {
+  type: 'navigate' | 'chat' | 'followup';
+  label: string;
+  path?: string;       // navigate 类型
+  prompt?: string;      // chat/followup 类型
+  page?: string;        // 兼容 ai-pacs 格式
+  sub_action?: string;
+  params?: Record<string, unknown>;
+}
+```
+
+#### 2.4 新增 navigate_page 工具
+
+**新增文件** `server/pkg/agent/tools/navigate_page.go`：
+
+```go
+type NavigatePageTool struct{}
+
+func (t *NavigatePageTool) Name() string { return "navigate_page" }
+func (t *NavigatePageTool) Description() string {
+    return "导航到互联网医院系统页面"
+}
+func (t *NavigatePageTool) Parameters() []agent.ToolParameter {
+    return []agent.ToolParameter{
+        {Name: "page", Type: "string", Description: "目标页面模块",
+         Required: true,
+         Enum: []string{
+             "admin/dashboard", "admin/patients", "admin/doctors",
+             "admin/consultations", "admin/prescription", "admin/pharmacy",
+             "admin/agents", "admin/workflows", "admin/knowledge",
+             "doctor/workbench", "doctor/consult",
+             "patient/home", "patient/consult",
+         }},
+        {Name: "action", Type: "string", Description: "操作类型: view/edit/add",
+         Required: false},
+        {Name: "id", Type: "string", Description: "记录ID", Required: false},
+    }
+}
+
+func (t *NavigatePageTool) Execute(ctx context.Context, params map[string]interface{}) (interface{}, error) {
+    page := params["page"].(string)
+    path := "/" + page
+    if action, ok := params["action"].(string); ok && action != "" {
+        if id, ok := params["id"].(string); ok && id != "" {
+            path = fmt.Sprintf("/%s/%s/%s", page, action, id)
+        }
+    }
+    return map[string]interface{}{
+        "action": "navigate",
+        "page":   path,
+        "label":  page,
+    }, nil
+}
+```
+
+#### 2.5 前端事件总线 + 导航处理
+
+**修改** 管理端/医生端/患者端的 Layout，添加全局事件监听：
+
+```tsx
+// 在 admin/layout.tsx、doctor layout、patient layout 中添加
+useEffect(() => {
+  const handler = (e: CustomEvent) => {
+    const { action, page } = e.detail || {};
+    if (action === 'navigate' && page) {
+      router.push(page);
+    }
+  };
+  window.addEventListener('ai-action', handler as EventListener);
+  return () => window.removeEventListener('ai-action', handler as EventListener);
+}, [router]);
+```
+
+#### 2.6 内嵌页面浏览
+
+参考 ai-pacs 的 `AiSidebar` 中 embed 功能，在 FloatContainer 全屏模式下支持左右分栏：
+
+```tsx
+// FloatContainer.tsx 全屏模式改造
+// 左侧 1/4: 对话面板
+// 右侧 3/4: iframe 嵌入页面
+
+const [embedUrl, setEmbedUrl] = useState<string | null>(null);
+
+// 全屏模式渲染
+{isFullscreen && (
+  <div style={{ display: 'flex', flex: 1, overflow: 'hidden' }}>
+    <div style={{ width: embedUrl ? '25%' : '100%', minWidth: 300, borderRight: embedUrl ? '1px solid #e5e7eb' : 'none' }}>
+      <ChatPanel role={role!} onEmbed={setEmbedUrl} />
+    </div>
+    {embedUrl && (
+      <div style={{ flex: 1, display: 'flex', flexDirection: 'column' }}>
+        {/* 地址栏 */}
+        <div style={{ padding: '6px 12px', background: '#f8fafc', borderBottom: '1px solid #e5e7eb', display: 'flex', alignItems: 'center', gap: 8 }}>
+          <span style={{ flex: 1, fontSize: 12, color: '#64748b', fontFamily: 'monospace' }}>
+            {window.location.origin}{embedUrl}
+          </span>
+          <Button size="small" onClick={() => { router.push(embedUrl); setEmbedUrl(null); }}>
+            在主页面打开
+          </Button>
+          <Button size="small" onClick={() => setEmbedUrl(null)}>关闭</Button>
+        </div>
+        <iframe src={embedUrl} style={{ flex: 1, border: 'none' }} />
+      </div>
+    )}
+  </div>
+)}
+```
+
+#### 2.7 键盘快捷键
+
+**修改** `web/src/app/(main)/admin/layout.tsx`（及其他Layout）：
+
+```tsx
+// Ctrl+K / Cmd+K 切换AI助手
+useEffect(() => {
+  const handler = (e: KeyboardEvent) => {
+    if ((e.ctrlKey || e.metaKey) && e.key === 'k') {
+      e.preventDefault();
+      const store = useAIAssistStore.getState();
+      store.isOpen ? store.closeWidget() : store.openWidget();
+    }
+  };
+  document.addEventListener('keydown', handler);
+  return () => document.removeEventListener('keydown', handler);
+}, []);
+```
+
+#### 2.8 Markdown 增强
+
+**修改** `web/src/components/MarkdownRenderer/index.tsx`，增加：
+
+```tsx
+// 1. 表格渲染（参考 ai-pacs ChatMessage.tsx 的 renderMarkdown）
+// 2. 代码块语法高亮
+// 3. 引号文本 → 可点击快捷发送按钮
+//    "查看处方" → <span data-quick-prompt="查看处方" class="quick-btn">查看处方 →</span>
+// 4. 有序/无序列表美化
+```
+
+---
+
+### Phase 3：角色管理模块（★★★★）
+
+#### 3.1 数据模型
+
+**新增文件** `server/internal/model/role.go`：
+
+```go
+// Role 角色表
+type Role struct {
+    ID          uint           `gorm:"primaryKey" json:"id"`
+    Code        string         `gorm:"type:varchar(50);uniqueIndex;not null" json:"code"`      // 角色编码: super_admin, hospital_admin, dept_admin, doctor, pharmacist, patient
+    Name        string         `gorm:"type:varchar(100);not null" json:"name"`                 // 角色名称
+    Description string         `gorm:"type:text" json:"description"`                           // 角色描述
+    Type        string         `gorm:"type:varchar(20);default:'custom'" json:"type"`           // system(系统内置不可删) / custom(自定义)
+    Status      string         `gorm:"type:varchar(20);default:'active'" json:"status"`         // active / disabled
+    Sort        int            `gorm:"default:0" json:"sort"`                                  // 排序
+    CreatedAt   time.Time      `json:"created_at"`
+    UpdatedAt   time.Time      `json:"updated_at"`
+    DeletedAt   gorm.DeletedAt `gorm:"index" json:"-"`
+
+    // 关联
+    Permissions []Permission   `gorm:"many2many:role_permissions;" json:"permissions,omitempty"`
+    Menus       []Menu         `gorm:"many2many:role_menus;" json:"menus,omitempty"`
+}
+
+// Permission 权限表
+type Permission struct {
+    ID          uint      `gorm:"primaryKey" json:"id"`
+    Code        string    `gorm:"type:varchar(100);uniqueIndex;not null" json:"code"`  // 权限编码: admin:user:list, admin:user:create
+    Name        string    `gorm:"type:varchar(100);not null" json:"name"`              // 权限名称
+    Module      string    `gorm:"type:varchar(50)" json:"module"`                      // 所属模块: user, consult, prescription, agent
+    Action      string    `gorm:"type:varchar(20)" json:"action"`                      // 操作: list, create, update, delete, export
+    Description string    `gorm:"type:text" json:"description"`
+    CreatedAt   time.Time `json:"created_at"`
+}
+
+// UserRole 用户-角色关联表（替代 User.Role 单字段）
+type UserRole struct {
+    ID     uint   `gorm:"primaryKey" json:"id"`
+    UserID string `gorm:"type:uuid;index;not null" json:"user_id"`
+    RoleID uint   `gorm:"index;not null" json:"role_id"`
+}
+```
+
+#### 3.2 预置角色与权限
+
+```go
+// 系统初始化时自动创建的角色
+var SystemRoles = []Role{
+    {Code: "super_admin",    Name: "超级管理员", Type: "system", Description: "拥有全部权限"},
+    {Code: "hospital_admin", Name: "医院管理员", Type: "system", Description: "管理端全部功能"},
+    {Code: "dept_admin",     Name: "科室管理员", Type: "system", Description: "管理本科室数据"},
+    {Code: "doctor",         Name: "医生",      Type: "system", Description: "在线问诊、开处方"},
+    {Code: "pharmacist",     Name: "药师",      Type: "system", Description: "处方审核"},
+    {Code: "patient",        Name: "患者",      Type: "system", Description: "在线就诊"},
+}
+
+// 权限粒度示例（共约 50+ 权限项）
+var SystemPermissions = []Permission{
+    // 用户管理
+    {Code: "admin:patient:list",   Name: "查看患者列表", Module: "user", Action: "list"},
+    {Code: "admin:patient:detail", Name: "查看患者详情", Module: "user", Action: "read"},
+    {Code: "admin:doctor:list",    Name: "查看医生列表", Module: "user", Action: "list"},
+    {Code: "admin:doctor:review",  Name: "医生资质审核", Module: "user", Action: "update"},
+    {Code: "admin:admin:list",     Name: "管理员列表",   Module: "user", Action: "list"},
+    {Code: "admin:admin:create",   Name: "创建管理员",   Module: "user", Action: "create"},
+    // 问诊管理
+    {Code: "admin:consult:list",   Name: "查看问诊列表", Module: "consult", Action: "list"},
+    {Code: "admin:consult:detail", Name: "查看问诊详情", Module: "consult", Action: "read"},
+    // 处方管理
+    {Code: "admin:rx:list",        Name: "处方列表",     Module: "prescription", Action: "list"},
+    {Code: "admin:rx:review",      Name: "处方审核",     Module: "prescription", Action: "update"},
+    // AI平台
+    {Code: "admin:agent:list",     Name: "Agent列表",    Module: "agent", Action: "list"},
+    {Code: "admin:agent:manage",   Name: "Agent管理",    Module: "agent", Action: "update"},
+    {Code: "admin:workflow:list",  Name: "工作流列表",   Module: "workflow", Action: "list"},
+    {Code: "admin:knowledge:list", Name: "知识库列表",   Module: "knowledge", Action: "list"},
+    // 系统管理
+    {Code: "admin:role:list",      Name: "角色列表",     Module: "system", Action: "list"},
+    {Code: "admin:role:manage",    Name: "角色管理",     Module: "system", Action: "update"},
+    {Code: "admin:menu:list",      Name: "菜单列表",     Module: "system", Action: "list"},
+    {Code: "admin:menu:manage",    Name: "菜单管理",     Module: "system", Action: "update"},
+    // ...更多权限
+}
+```
+
+#### 3.3 后端服务层
+
+**新增文件** `server/internal/service/admin/role_service.go`：
+
+```go
+// RoleService 角色管理服务
+type RoleService struct {
+    db *gorm.DB
+}
+
+func (s *RoleService) ListRoles(ctx context.Context, keyword string, status string) ([]model.Role, error)
+func (s *RoleService) GetRole(ctx context.Context, id uint) (*model.Role, error)
+func (s *RoleService) CreateRole(ctx context.Context, req *CreateRoleReq) error
+func (s *RoleService) UpdateRole(ctx context.Context, id uint, req *UpdateRoleReq) error
+func (s *RoleService) DeleteRole(ctx context.Context, id uint) error
+func (s *RoleService) AssignPermissions(ctx context.Context, roleID uint, permissionIDs []uint) error
+func (s *RoleService) AssignMenus(ctx context.Context, roleID uint, menuIDs []uint) error
+func (s *RoleService) GetRolePermissions(ctx context.Context, roleID uint) ([]model.Permission, error)
+func (s *RoleService) GetRoleMenus(ctx context.Context, roleID uint) ([]model.Menu, error)
+func (s *RoleService) GetUserPermissions(ctx context.Context, userID string) ([]string, error)  // 返回权限code列表
+```
+
+#### 3.4 后端API
+
+```
+GET    /admin/roles                     → 角色列表（含权限统计）
+GET    /admin/roles/:id                 → 角色详情（含权限+菜单）
+POST   /admin/roles                     → 创建角色
+PUT    /admin/roles/:id                 → 更新角色
+DELETE /admin/roles/:id                 → 删除角色（系统角色不可删）
+PUT    /admin/roles/:id/permissions     → 分配权限 { permission_ids: [1,2,3] }
+PUT    /admin/roles/:id/menus           → 分配菜单 { menu_ids: [1,2,3] }
+GET    /admin/permissions               → 全部权限列表（按模块分组）
+PUT    /admin/users/:id/roles           → 给用户分配角色 { role_ids: [1,2] }
+GET    /admin/users/:id/permissions     → 查询用户有效权限
+```
+
+#### 3.5 中间件改造
+
+**修改** `server/pkg/middleware/auth.go`，新增权限校验中间件：
+
+```go
+// RequirePermission 权限校验中间件
+func RequirePermission(permCode string) gin.HandlerFunc {
+    return func(c *gin.Context) {
+        userID := c.GetString("user_id")
+        permissions := getUserPermissionCodes(userID) // 从 Redis 缓存或DB查
+        if !contains(permissions, permCode) {
+            c.JSON(403, gin.H{"error": "权限不足", "required": permCode})
+            c.Abort()
+            return
+        }
+        c.Next()
+    }
+}
+
+// 路由注册示例
+adminGroup.GET("/patients", middleware.RequirePermission("admin:patient:list"), handler.GetPatients)
+```
+
+#### 3.6 前端页面
+
+**新增文件** `web/src/app/(main)/admin/roles/page.tsx`：
+
+```

+
+**前端API** `web/src/api/role.ts`：
+
+```ts
+export const roleApi = {
+  list: (params?: { keyword?: string; status?: string }) =>
+    get<Role[]>('/admin/roles', { params }),

+};
+```
+
+---
+
+### Phase 4：菜单管理模块（★★★★）
+
+#### 4.1 数据模型
+
+**新增文件** `server/internal/model/menu.go`：
+
+```go
+// Menu 菜单表
+type Menu struct {
+    ID        uint           `gorm:"primaryKey" json:"id"`

+}
+```
+
+#### 4.2 预置菜单数据
+
+```go
+// 系统初始化时创建的菜单（与现有 admin/layout.tsx 硬编码菜单对齐）
+var SystemMenus = []Menu{
+    {Code: "dashboard",     Name: "运营大盘",    Path: "/admin/dashboard",      Icon: "DashboardOutlined",   Sort: 1},

+
+#### 4.3 后端服务层
+
+**新增文件** `server/internal/service/admin/menu_service.go`：

+
+#### 4.4 后端API
+
+```
+GET    /admin/menus                     → 全部菜单树
+GET    /admin/menus/user                → 当前用户可见菜单树（前端渲染用）

+PUT    /admin/menus/sort                → 批量排序 { items: [{id:1, sort:1, parent_id:null}, ...] }
+```
+
+#### 4.5 前端页面
+
+**新增文件** `web/src/app/(main)/admin/menus/page.tsx`：
+
+```

+```
+
+核心交互：
+- **树形拖拽排序**：使用 `@ant-design/pro-components` 的 `DndContext` 或 `dnd-kit` 实现
+- **点击编辑**：点击菜单项，右侧显示编辑表单
+- **图标选择器**：下拉选择 Ant Design 图标
+- **实时预览**：修改后左侧树实时刷新
+
+**前端API** `web/src/api/menu.ts`：
+
+```ts
+export const menuApi = {
+  tree: () => get<Menu[]>('/admin/menus'),
+  userTree: () => get<Menu[]>('/admin/menus/user'),
+  create: (data: CreateMenuReq) => post('/admin/menus', data),
+  update: (id: number, data: UpdateMenuReq) => put(`/admin/menus/${id}`, data),
+  delete: (id: number) => del(`/admin/menus/${id}`),
+  sort: (items: MenuSortItem[]) => put('/admin/menus/sort', { items }),
+};
+```
+
+#### 4.6 动态菜单渲染改造
+
+**修改** `web/src/app/(main)/admin/layout.tsx`：
+
+```tsx
+// 现有：硬编码 menuItems 数组
+// 改造后：从 API 获取 + 缓存
+
+const [dynamicMenus, setDynamicMenus] = useState<MenuItem[]>([]);
+
+useEffect(() => {
+  // 优先从 localStorage 读取缓存
+  const cached = localStorage.getItem('admin_menus');
+  if (cached) {
+    setDynamicMenus(JSON.parse(cached));
+  }
+  // 异步刷新
+  menuApi.userTree().then(res => {
+    const items = buildAntdMenuItems(res.data);
+    setDynamicMenus(items);
+    localStorage.setItem('admin_menus', JSON.stringify(items));
+  });
+}, []);
+
+// 菜单树转 Ant Design Menu items
+function buildAntdMenuItems(menus: Menu[]): MenuItem[] {
+  return menus
+    .filter(m => m.visible && m.status === 'active')
+    .sort((a, b) => a.sort - b.sort)
+    .map(m => ({
+      key: m.path || m.code,
+      icon: getIconComponent(m.icon),  // 动态加载 Ant Design 图标
+      label: m.name,
+      children: m.children?.length ? buildAntdMenuItems(m.children) : undefined,
+    }));
+}
+```
+
+---
+
+## 五、User 模型与权限兼容改造
+
+### 5.1 User 表改造
+
+```go
+// 保留 Role 字段做向后兼容，新增 UserRole 关联
+type User struct {
+    // ...原有字段保持不变...
+    Role string `gorm:"type:varchar(20);default:'patient'" json:"role"` // 保留作为快捷字段
+
+    // 新增关联
+    Roles []Role `gorm:"many2many:user_roles;" json:"roles,omitempty"`
+}
+```
+
+### 5.2 兼容策略
+
+1. **双写**：创建/修改用户时，同时写 `User.Role` 和 `user_roles` 关联表
+2. **读取优先级**：`user_roles` 表优先，若为空则回退到 `User.Role` 字段
+3. **前端适配**：登录返回的 `user` 对象增加 `permissions: string[]` 和 `menus: Menu[]`
+
+### 5.3 前端权限控制
+
+```tsx
+// 新增 Hook: usePermission
+export function usePermission() {
+  const { user } = useUserStore();
+  const permissions = user?.permissions || [];
+
+  const hasPermission = useCallback((code: string) => {
+    if (user?.role === 'super_admin') return true;  // 超管拥有全部权限
+    return permissions.includes(code);
+  }, [permissions, user]);
+
+  return { hasPermission };
+}
+
+// 使用示例
+const { hasPermission } = usePermission();
+{hasPermission('admin:patient:create') && <Button>新建患者</Button>}
+```
+

+
+## 三、升级改造方案
+
+### Phase 1：Tool 智能筛选（核心安全需求）
+
+> 提示词要求：**严禁将全量 Tool 列表暴露给模型**，仅向模型提供最小必要工具集
+
+#### 3.1.1 问题
+
+当前 `buildAgentFromDef` 将 Agent 定义中的 **全部 Tools** 传给 OpenAI，当 Tool 数量增长到 50+ 时：
+- Token 消耗大幅增加
+- 模型选择准确率下降
+- 安全风险：模型可见不必要的能力
+
+#### 3.1.2 方案
+
+**后端新增 Tool 筛选层**
+
+```
+用户消息 → 向量召回 Top20 → LLM 精排 Top5 → 传入 ReAct 推理
+```
+
+**实现步骤：**
+
+1. **新增文件** `pkg/agent/tool_selector.go`
+
+```go
+// ToolSelector 工具智能筛选器
+type ToolSelector struct {
+    embedder  EmbeddingProvider    // 复用 RAG 的 Embedder
+    toolIndex map[string][]float64 // tool_name → embedding 向量
+}
+
+// Select 根据用户意图筛选最相关的 Tool
+func (s *ToolSelector) Select(ctx context.Context, query string, candidates []string, topK int) []string {
+    // 1. 向量召回 Top20
+    // 2. LLM 精排 Top5
+    // 3. 返回筛选后的 tool names
+}
+```
+
+2. **修改** `pkg/agent/react_agent.go` 的 `RunStream` 方法
+
+```go
+// 在构建 tool schemas 之前增加筛选步骤
+func (a *ReActAgent) RunStream(...) {
+    // 新增：根据用户消息筛选 tools
+    selectedTools := a.selector.Select(ctx, input.Message, a.cfg.Tools, 5)
+    // 使用筛选后的 tools 构建 schema
+    toolSchemas := a.registry.GetSchemas(selectedTools)
+    ...
+}
+```
+
+3. **新增数据库字段** `agent_tools` 表
+
+```sql
+ALTER TABLE agent_tools ADD COLUMN embedding vector(1536);  -- pgvector
+ALTER TABLE agent_tools ADD COLUMN usage_count int DEFAULT 0;
+ALTER TABLE agent_tools ADD COLUMN avg_score float DEFAULT 0;
+```
+
+4. **工具注册时自动生成 embedding**
+
+在 `syncToolsToDB` 中，对每个 Tool 的 `name + description + parameters` 生成向量并存储。
+
+**影响范围：**
+- 新增：`pkg/agent/tool_selector.go`
+- 修改：`pkg/agent/react_agent.go`（RunStream 增加筛选）
+- 修改：`internal/agent/init.go`（syncToolsToDB 增加 embedding）
+- 修改：`internal/model/agent.go`（AgentTool 增加字段）
+
+---
+
+### Phase 2：热代码 Tool 自动生成
+
+> 提示词要求：当现有 Tool 无法满足需求时，自动生成标准化工具代码
+
+#### 3.2.1 问题
+
+当前只能通过以下方式添加 Tool：
+- 手动写 Go 代码（需重新编译部署）
+- 通过 HTTP Tool 管理界面配置（仅限 HTTP 调用）
+
+无法像提示词所述自动生成代码并热加载。
+
+#### 3.2.2 方案
+
+**基于"模板化 SQL/HTTP Tool"的可行方案**（Go 不支持 Python 式热加载，但可以：）
+
+1. **新增 `CodeGenTool`** — LLM 生成的不是 Go 代码，而是**结构化 Tool 配置**
+
+```go
+// pkg/agent/tools/code_gen_tool.go
+
+type CodeGenTool struct{}
+
+func (t *CodeGenTool) Name() string { return "generate_tool" }
+func (t *CodeGenTool) Description() string {
+    return "当现有工具无法完成任务时，自动生成新的工具定义并注册"
+}
+
+func (t *CodeGenTool) Execute(ctx context.Context, params map[string]interface{}) (interface{}, error) {
+    // 1. 分析任务需求
+    // 2. 判断适合 SQL Tool 还是 HTTP Tool
+    // 3. 生成 Tool 配置（SQL模板/HTTP配置）
+    // 4. 写入数据库 + 注册到 ToolRegistry
+    // 5. 返回生成结果
+}
+```
+
+2. **新增 `DynamicSQLTool`** — 基于数据库的 SQL 查询工具
+
+```go
+// 新增文件: pkg/agent/tools/sql_tool.go
+
+type SQLToolDefinition struct {
+    ID           uint   `gorm:"primaryKey"`
+    Name         string `gorm:"uniqueIndex"`
+    Description  string
+    SQLTemplate  string // SELECT * FROM users WHERE {{condition}}
+    Parameters   string // JSON
+    ResultFormat string // table / single / count
+    Status       string
+}
+
+type DynamicSQLTool struct {
+    def *SQLToolDefinition
+}
+```
+
+3. **Tool 自动生成流程**
+
+```
+用户请求 → Agent 判断无匹配 Tool
+  → 调用 generate_tool
+    → LLM 分析任务 → 生成 SQL/HTTP 配置
+    → 写入 sql_tool_definitions / http_tool_definitions 表
+    → 热注册到 ToolRegistry（无需重启）
+    → 执行新 Tool 并返回结果
+```
+
+4. **新增数据库表** `sql_tool_definitions`
+
+```sql
+CREATE TABLE sql_tool_definitions (
+    id SERIAL PRIMARY KEY,
+    name VARCHAR(100) UNIQUE NOT NULL,
+    display_name VARCHAR(200),
+    description TEXT,
+    sql_template TEXT NOT NULL,       -- SQL 模板，支持 {{param}} 占位符
+    parameters JSONB DEFAULT '[]',    -- 参数定义
+    result_format VARCHAR(20) DEFAULT 'table',  -- table/single/count
+    read_only BOOLEAN DEFAULT true,   -- 只允许 SELECT
+    status VARCHAR(20) DEFAULT 'active',
+    created_by VARCHAR(100),
+    created_at TIMESTAMP DEFAULT NOW(),
+    updated_at TIMESTAMP DEFAULT NOW()
+);
+```
+
+**安全约束：**
+- SQL Tool 默认只允许 SELECT（read_only=true）
+- 新生成的 Tool 先标记为 `pending_review`
+- 管理员审核通过后才标记为 `active`
+- 所有生成操作记录到 `system_logs`
+
+**影响范围：**
+- 新增：`pkg/agent/tools/code_gen_tool.go`
+- 新增：`pkg/agent/tools/sql_tool.go`
+- 新增：`internal/model/sql_tool.go`
+- 修改：`internal/agent/init.go`（加载 SQL Tools）
+- 修改：`internal/agent/handler.go`（SQL Tool 管理 API）
+
+---
+
+### Phase 3：前端路由标准化 & 事件封装
+
+> 提示词要求：`{模块}/edit/{id}`、`{模块}/add/{id}` 标准化路由 + navigation_event 封装
+
+#### 3.3.1 问题
+
+当前前端路由不统一：
+```
+/admin/doctors         ← 列表页 ✅ 符合
+/patient/consult/text/[id]  ← 非标准格式
+/patient/consult/create     ← 非 add/{id} 格式
+/doctor/patient/[id]        ← 非标准格式
+```
+
+AI 导航事件仅有简单的 `ai-action` CustomEvent，缺乏结构化。
+
+#### 3.3.2 方案
+
+**3.3.2.1 路由注册表**
+
+新增前端路由注册表，将所有页面路由标准化管理：
+
+```typescript
+// web/src/config/routes.ts
+
+export interface RouteDefinition {
+  code: string;           // 业务模块标识
+  path: string;           // Next.js 实际路由
+  name: string;           // 中文名称
+  permissions?: string[]; // 需要的权限
+  operations: {           // 支持的操作
+    list?: string;        // 列表页路由
+    detail?: string;      // 详情页路由模板 (含 :id)
+    add?: string;         // 新增页路由模板
+    edit?: string;        // 编辑页路由模板 (含 :id)
+  };
+}
+
+export const ROUTE_REGISTRY: RouteDefinition[] = [
+  {
+    code: 'admin_dashboard',
+    path: '/admin/dashboard',
+    name: '管理仪表盘',
+    permissions: ['admin:dashboard:view'],
+    operations: {
+      list: '/admin/dashboard',
+    },
+  },
+  {
+    code: 'admin_patients',
+    path: '/admin/patients',
+    name: '患者管理',
+    permissions: ['admin:patients:list'],
+    operations: {
+      list: '/admin/patients',
+      detail: '/admin/patients/:id',
+      edit: '/admin/patients/edit/:id',
+    },
+  },
+  {
+    code: 'admin_doctors',
+    path: '/admin/doctors',
+    name: '医生管理',
+    permissions: ['admin:doctors:list'],
+    operations: {
+      list: '/admin/doctors',
+      detail: '/admin/doctors/:id',
+      edit: '/admin/doctors/edit/:id',
+      add: '/admin/doctors/add/0',
+    },
+  },
+  // ... 50+ 页面全部注册
+];
+
+// 工具函数
+export function resolveRoute(code: string, operation: string, params?: Record<string, string>): string | null {
+  const def = ROUTE_REGISTRY.find(r => r.code === code);
+  if (!def) return null;
+  let path = def.operations[operation as keyof typeof def.operations];
+  if (!path) return null;
+  if (params) {
+    Object.entries(params).forEach(([k, v]) => {
+      path = path!.replace(`:${k}`, v);
+    });
+  }
+  return path;
+}
+```
+
+**3.3.2.2 前端事件标准化**
+
+```typescript
+// web/src/lib/navigation-event.ts
+
+export interface NavigationEvent {
+  type: 'navigation_event';
+  page_code: string;       // 业务模块标识
+  intent: string;          // view_list | view_detail | edit | add
+  route: string;           // 实际路由
+  params: Record<string, unknown>;
+}
+
+// 发送导航事件给 AI Agent
+export function emitNavigationEvent(event: NavigationEvent) {
+  window.dispatchEvent(new CustomEvent('ai-navigation', { detail: event }));
+}
+
+// 从 AI 指令解析并执行导航
+export function executeNavigationAction(action: {
+  action: string;
+  page: string;
+  operation: string;
+  route: string;
+  params: Record<string, unknown>;
+}) {
+  // 1. 校验权限
+  // 2. 解析路由
+  // 3. 执行跳转
+  window.dispatchEvent(new CustomEvent('ai-action', {
+    detail: { action: 'navigate', page: action.route },
+  }));
+}
+```
+
+**3.3.2.3 后端 navigate_page Tool 升级**
+
+```go
+// 升级 navigate_page.go
+
+func (t *NavigatePageTool) Parameters() []agent.ToolParameter {
+    return []agent.ToolParameter{
+        {
+            Name:        "page_code",
+            Type:        "string",
+            Description: "业务模块标识（如 admin_doctors, patient_consult）",
+            Required:    true,
+        },
+        {
+            Name:        "operation",
+            Type:        "string",
+            Description: "操作类型",
+            Required:    false,
+            Enum:        []string{"open_list", "open_detail", "open_edit", "open_add"},
+        },
+        {
+            Name:        "id",
+            Type:        "string",
+            Description: "记录ID（detail/edit 时使用）",
+            Required:    false,
+        },
+    }
+}
+
+func (t *NavigatePageTool) Execute(ctx context.Context, params map[string]interface{}) (interface{}, error) {
+    pageCode, _ := params["page_code"].(string)
+    operation, _ := params["operation"].(string)
+    id, _ := params["id"].(string)
+
+    // 从路由注册表查找
+    route := resolveRoute(pageCode, operation, id)
+
+    // 返回标准化导航指令
+    return map[string]interface{}{
+        "action":    "navigate",
+        "page":      pageCode,
+        "operation": operation,
+        "route":     route,
+        "params":    map[string]interface{}{"id": id},
+    }, nil
+}
+```
+
+**影响范围：**
+- 新增：`web/src/config/routes.ts`
+- 新增：`web/src/lib/navigation-event.ts`
+- 修改：`web/src/app/(main)/admin/layout.tsx`（监听标准化事件）
+- 修改：`pkg/agent/tools/navigate_page.go`（输出标准化指令）
+- 修改：`pkg/agent/react_agent.go`（System Prompt 增加路由表）
+
+---
+
+### Phase 4：路由权限联动
+
+> 提示词要求：导航指令需同步校验权限边界
+
+#### 3.4.1 方案
+
+在 `navigate_page` Tool 中增加权限校验：
+
+```go
+func (t *NavigatePageTool) Execute(ctx context.Context, params map[string]interface{}) (interface{}, error) {
+    // ... 解析参数
+
+    // 从 context 获取 userID
+    userID, _ := ctx.Value("user_id").(string)
+
+    // 校验权限
+    required := getRoutePermissions(pageCode)
+    if !checkUserPermission(userID, required) {
+        return map[string]interface{}{
+            "action":  "permission_denied",
+            "page":    pageCode,
+            "message": "您没有访问该页面的权限",
+        }, nil
+    }
+
+    // 正常返回导航指令
+    return map[string]interface{}{
+        "action":    "navigate",
+        "page":      pageCode,
+        "operation": operation,
+        "route":     route,
+    }, nil
+}
+```
+
+**影响范围：**
+- 修改：`pkg/agent/tools/navigate_page.go`（增加权限校验）
+- 修改：`pkg/agent/react_agent.go`（传递 userID 到 context）
+
+---
+
+### Phase 5：Skill 升级为多 Agent 协作编排
+
+> 提示词要求：Skill 由多 Agent 协作编排逻辑构成，支持串行/并行/DAG
+
+#### 3.5.1 问题
+
+当前 Skill 仅是 `Tools + SystemPromptAddon`，本质上只是一个 Tool 集合，没有真正的多 Agent 协作。
+
+#### 3.5.2 方案
+
+**升级 AgentSkill 模型**
+
+```go
+// internal/model/agent_skill.go (升级)
+
+type AgentSkill struct {
+    ID                uint      `gorm:"primaryKey"`
+    SkillID           string    `gorm:"uniqueIndex"`
+    Name              string
+    Description       string
+    Category          string
+    // 保留原有字段
+    Tools             string    `gorm:"type:jsonb;default:'[]'"`
+    SystemPromptAddon string
+    QuickReplies      string    `gorm:"type:jsonb;default:'[]'"`
+    Icon              string
+    // 新增：多 Agent 编排
+    OrchestrationMode string    `gorm:"type:varchar(20);default:'simple'"` // simple | serial | parallel | dag
+    AgentSteps        string    `gorm:"type:jsonb;default:'[]'"`           // Agent 编排步骤
+    ContextSchema     string    `gorm:"type:jsonb;default:'{}'"`
+    Status            string    `gorm:"type:varchar(20);default:'active'"`
+    CreatedAt         time.Time
+    UpdatedAt         time.Time
+}
+```
+
+**AgentSteps JSON 格式：**
+
+```json
+[
+  {
+    "step_id": "step_1",
+    "agent_id": "symptom_analyzer",
+    "input_mapping": {"message": "{{user_message}}"},
+    "output_key": "analysis_result"
+  },
+  {
+    "step_id": "step_2",
+    "agent_id": "dept_recommender",
+    "depends_on": ["step_1"],
+    "input_mapping": {"symptoms": "{{step_1.analysis_result}}"},
+    "output_key": "recommendation"
+  }
+]
+```
+
+**新增 Skill 执行引擎：**
+
+```go
+// pkg/agent/skill_executor.go
+
+type SkillExecutor struct {
+    agentService AgentServiceInterface
+}
+
+func (e *SkillExecutor) Execute(ctx context.Context, skill model.AgentSkill, input map[string]interface{}) (map[string]interface{}, error) {
+    switch skill.OrchestrationMode {
+    case "serial":
+        return e.executeSerial(ctx, skill, input)
+    case "parallel":
+        return e.executeParallel(ctx, skill, input)
+    case "dag":
+        return e.executeDAG(ctx, skill, input)
+    default:
+        // simple 模式：与现有行为兼容
+        return e.executeSimple(ctx, skill, input)
+    }
+}
+```
+
+**影响范围：**
+- 修改：`internal/model/agent_skill.go`（增加字段）
+- 新增：`pkg/agent/skill_executor.go`
+- 修改：`internal/agent/service.go`（Chat 流程增加 Skill 编排判断）
+- 修改：`internal/agent/skill_handler.go`（管理 API 支持新字段）
+
+---
+
+### Phase 6：Agent 输出标准化
+
+> 提示词要求：固定 JSON 结构输出 execution_plan / navigation_actions 等
+
+#### 3.6.1 方案
+
+**升级 AgentOutput 结构**
+
+```go
+// pkg/agent/react_agent.go (修改)
+
+type AgentOutput struct {
+    Response     string           `json:"response"`
+    ToolCalls    []ToolCallResult `json:"tool_calls,omitempty"`
+    Iterations   int              `json:"iterations"`
+    FinishReason string           `json:"finish_reason"`
+    TotalTokens  int              `json:"total_tokens"`
+    TraceID      string           `json:"trace_id,omitempty"`
+    // 新增：标准化输出
+    ExecutionPlan     []PlanStep          `json:"execution_plan,omitempty"`
+    NavigationActions []NavigationAction  `json:"navigation_actions,omitempty"`
+    NewToolsGenerated []string            `json:"new_tools_generated,omitempty"`
+}
+
+type PlanStep struct {
+    Step        int    `json:"step"`
+    Action      string `json:"action"`
+    Tool        string `json:"tool,omitempty"`
+    Description string `json:"description"`
+    Status      string `json:"status"` // pending | running | done | failed
+}
+
+type NavigationAction struct {
+    Action    string                 `json:"action"`
+    Page      string                 `json:"page"`
+    Operation string                 `json:"operation"`
+    Route     string                 `json:"route"`
+    Params    map[string]interface{} `json:"params"`
+}
+```
+
+**前端适配：**
+
+```typescript
+// 在 ChatPanel 中处理标准化输出
+if (output.navigation_actions?.length > 0) {
+    output.navigation_actions.forEach(action => {
+        executeNavigationAction(action);
+    });
+}
+
+if (output.execution_plan?.length > 0) {
+    // 渲染执行计划卡片
+    renderExecutionPlan(output.execution_plan);
+}
+```
+
+---
+
+### Phase 7：Tool 质量评分 & 可观测性
+
+> 提示词要求：支持调用统计、质量评分、失效清理
+
+#### 3.7.1 方案
+
+**升级 AgentTool 表**
+
+```sql
+ALTER TABLE agent_tools ADD COLUMN usage_count INT DEFAULT 0;
+ALTER TABLE agent_tools ADD COLUMN success_count INT DEFAULT 0;
+ALTER TABLE agent_tools ADD COLUMN avg_duration_ms INT DEFAULT 0;
+ALTER TABLE agent_tools ADD COLUMN quality_score FLOAT DEFAULT 0;     -- 0-100
+ALTER TABLE agent_tools ADD COLUMN last_used_at TIMESTAMP;
+ALTER TABLE agent_tools ADD COLUMN auto_disabled BOOLEAN DEFAULT false; -- 自动禁用
+```
+
+**新增 Tool 监控服务：**
+
+```go
+// pkg/agent/tool_monitor.go
+
+// UpdateToolMetrics 每次工具调用后更新指标
+func UpdateToolMetrics(toolName string, success bool, durationMs int) {
+    db := database.GetDB()
+    if success {
+        db.Model(&model.AgentTool{}).Where("name = ?", toolName).Updates(map[string]interface{}{
+            "usage_count":     gorm.Expr("usage_count + 1"),
+            "success_count":   gorm.Expr("success_count + 1"),
+            "last_used_at":    time.Now(),
+        })
+    } else {
+        db.Model(&model.AgentTool{}).Where("name = ?", toolName).Updates(map[string]interface{}{
+            "usage_count":  gorm.Expr("usage_count + 1"),
+            "last_used_at": time.Now(),
+        })
+    }
+}
+
+// AutoDisableUnhealthyTools 自动禁用低质量 Tool
+func AutoDisableUnhealthyTools() {
+    // 成功率低于 50% 且调用次数 > 100 的自动禁用
+}
+```
+

+## 七、架构对比
+
+### 改造前
+

提示词.txt

+你是一名**企业级 AI 架构生成与编排专家**，负责基于系统现有数据资产，自动化构建可复用、可扩展、可治理、可视化的 Tool-Agent-Skill 三层 AI 能力体系，同时实现前端路由与交互的模型驱动标准化。
+
+## 一、系统基线资源
+你可直接使用并依赖以下已完备的系统资产：
+- 全量后端接口定义与能力边界
+- 全量数据库表结构、字段、关联关系
+- 全量前端页面结构、交互逻辑、路由体系
+- 全量菜单树与权限路由体系
+
+## 二、核心目标
+以**数据库结构为核心驱动源**，全自动完成：
+1. 从数据表/接口反向生成标准化 Tool
+2. 基于 Tool 组装与生成专用 Agent
+3. 基于多 Agent 协作编排形成高阶 Skill
+4. 实现前端路由与操作的模型驱动、指令化与标准化
+5. 构建一套可自进化、可观测、可管控的企业级 AI 编排框架
+
+## 三、执行优先级与决策链路（严格遵循）
+1. **优先复用**：优先匹配并调用系统中已注册、可复用的 Tool；
+2. **Tool 缺失则自动生成**：若无匹配 Tool，自动生成热代码 Tool → 入库 → 注册 → 测试验证 → 正式启用；
+3. **单 Tool 无法完成 → 尝试单 Agent**：由单个 Agent 绑定多 Tool 完成任务；
+4. **单 Agent 无法完成 → 检索已有 Skill**：优先使用已编排完成的高阶能力；
+5. **Skill 缺失 → 自动任务拆解**：由 LLM 对复杂任务进行结构化拆解，识别子任务依赖与执行顺序；
+6. **按需生成缺失 Agent**：为子任务创建专用智能体并绑定对应 Tool；
+7. **按序编排为新 Skill**：以串行/并行/DAG 方式将多 Agent 组装为 Skill；
+8. **注册入库并执行**：Skill 完成注册后正式投入使用。
+
+## 四、Tool 筛选与安全策略（强制约束）
+1. 第一层：通过向量检索召回 Top20 候选 Tool；
+2. 第二层：通过 LLM 语义精排筛选 Top5 最优 Tool；
+3. 安全约束：**严禁将全量 Tool 列表暴露给模型**，仅向模型提供最小必要工具集。
+
+## 五、热代码 Tool 自动生成机制（核心能力）
+当判定现有 Tool 无法满足任务需求时，自动执行：
+1. 分析任务所需接口/逻辑/数据操作；
+2. 生成标准化 Python 热代码函数；
+3. 写入 `ai_tool` 数据表并完成元信息注册；
+4. 自动集成到 LangChain 生态；
+5. 生成单元测试并执行验证；
+6. 验证通过后标记为正式可用 Tool。
+
+## 六、Agent 与 Skill 构建规范
+- **Agent**：由「限定范围 Tool 集合 + 系统指令 + 记忆策略」构成，通过 `ai_agent` 与 `ai_agent_tool` 表管理；
+- **Skill**：由「多 Agent 协作编排逻辑」构成，支持串行、并行、DAG 三种编排模式，通过 `ai_skill` 与 `ai_skill_agent` 表管理。
+
+## 七、前端模型驱动导航与路由规范（核心补充）
+### 7.1 前端路由标准化格式
+所有前端页面路由需严格遵循以下结构：
+- 列表页：`{业务模块标识}`（例：user_management、role_config）
+- 编辑页：`{业务模块标识}/edit/{id}`（例：user_management/edit/123、role_config/edit/456）
+- 新增页：`{业务模块标识}/add/{id}`（注：{id} 为关联父级ID，无父级时填充 `0`，例：user_management/add/0、dept_config/add/789）
+
+### 7.2 前端事件封装规则
+前端所有菜单点击、页面跳转、操作触发行为，需统一封装为「自然语言意图 + 结构化路由事件」后发送给 Agent，示例格式：
+```json
+{
+  "type": "navigation_event",
+  "page_code": "user_management",
+  "intent": "view_list",
+  "route": "user_management",
+  "params": {}
+}
+```
+```json
+{
+  "type": "navigation_event",
+  "page_code": "user_management",
+  "intent": "edit_user",
+  "route": "user_management/edit/123",
+  "params": {"id": 123}
+}
+```
+
+### 7.3 Agent 输出指令规范
+Agent 需输出包含标准化路由的结构化执行指令，前端仅负责解析并跳转至指定路由，示例：
+```json
+{
+  "action": "navigate",
+  "page": "user_management",
+  "operation": "open_edit",
+  "route": "user_management/edit/123",
+  "params": {"id": 123}
+}
+```
+```json
+{
+  "action": "navigate",
+  "page": "user_management",
+  "operation": "open_add",
+  "route": "user_management/add/0",
+  "params": {"parent_id": 0}
+}
+```
+
+### 7.4 路由与权限联动
+生成导航指令时，需同步校验目标路由的权限边界，确保输出的路由指令符合当前用户的权限范围，无权限时需返回标准化的权限提示指令。
+
+## 八、输出格式（严格遵循）
+所有决策与执行结果必须以固定 JSON 结构输出：
+```json
+{
+  "execution_plan": [],
+  "required_tools": [],
+  "new_tools_generated": [],
+  "agents_used": [],
+  "skill_created": null,
+  "navigation_actions": []
+}
+```
+其中 `navigation_actions` 字段需包含标准化路由信息，示例：
+```json
+"navigation_actions": [
+  {
+    "action": "navigate",
+    "page": "user_management",
+    "operation": "open_list",
+    "route": "user_management",
+    "params": {}
+  }
+]
+```
+
+## 九、架构设计核心原则（不可妥协）
+1. **可复用**：Tool/Agent/Skill 支持跨场景重复使用，前端路由支持跨页面复用；
+2. **可扩展**：支持无缝新增工具、智能体、技能、编排逻辑与前端路由；
+3. **可注册**：所有能力组件与路由规则支持统一注册、版本管理、状态管控；
+4. **可视化**：提供 Tool/Agent/Skill 与路由链路的可视化管理、调试、编排界面；
+5. **可治理**：支持权限、审计、调用统计、失效清理、质量评分全生命周期管控。
+
+### 总结
+1. 核心新增：明确前端路由标准化格式（列表页`xxx`、编辑页`xxx/edit/{id}`、新增页`xxx/add/{id}`），并关联前端事件封装与Agent指令输出，同步校验路由权限；
+2. 核心保留：Tool-Agent-Skill 三层能力体系的生成逻辑、Tool筛选策略、热代码生成机制、输出格式规范；
+3. 核心原则：所有组件与路由均需满足可复用、可扩展、可注册、可视化、可治理的企业级要求。
