+## 核心要点说明
+
+### 1. 双层插件架构
+
+| 层级 | 技术方案 | 性能 | 适用场景 | 开发语言 |
+|------|---------|------|---------|---------|
+| **Tier 1<br/>编译时插件** | 编译时链接 | 100%<br/>零损失 | • 核心Channel（OpenAI等）<br/>• 内置Hook<br/>• 高频调用路径 | Go only |
+| **Tier 2<br/>运行时插件** | go-plugin<br/>gRPC | 90-95%<br/>5-10%开销 | • 第三方扩展<br/>• 企业定制<br/>• 多语言集成 | Go/Python/<br/>Node.js/Rust |
+
+### 2. 核心组件
+
+#### Core层（核心引擎）
+- **interfaces/**: 定义ChannelPlugin、RelayHook、MiddlewarePlugin接口
+- **registry/**: 线程安全的插件注册中心，支持O(1)查找、优先级排序
+
+#### Relay Hook链
+- **执行流程**: OnBeforeRequest → Channel.DoRequest → OnAfterResponse
+- **特性**: 优先级排序、短路机制、数据共享（HookContext.Data）
+- **应用场景**: 联网搜索、内容过滤、日志增强、缓存策略
+
+### 3. Tier 1: 编译时插件（已实施 ✅）
+
+**特点**:
+- 零性能损失，编译后与硬编码无差异
+- init()函数自动注册到Registry
+- YAML配置启用/禁用
+
+**已实现**:
+- ✅ 31个Channel插件（OpenAI、Claude、Gemini等）
+- ✅ 2个Hook插件（web_search、content_filter）
+- ✅ Hook执行链
+- ✅ 配置系统（支持环境变量展开）
+
+### 4. Tier 2: 运行时插件（待实施 🚧）
+
+**基于**: [hashicorp/go-plugin](https://github.com/hashicorp/go-plugin)（Vault/Terraform使用）
+
+**优势**:
+- ✅ 进程隔离（第三方代码崩溃不影响主程序）
+- ✅ 多语言支持（gRPC协议）
+- ✅ 热插拔（无需重启）
+- ✅ 安全验证（Ed25519签名 + SHA256校验 + TLS加密）
+- ✅ 独立分发（插件商店）
+
+**适用场景**:
+- 第三方开发者扩展
+- 企业定制业务逻辑
+- Python ML模型集成
+- 第三方服务集成（Slack/钉钉/企业微信）
+- UI扩展
+
+### 5. 安全机制
+
+**Tier 1（编译时）**:
+- 内部代码审查
+- 编译期类型安全
+
+**Tier 2（运行时）**:
+- Ed25519签名验证
+- SHA256校验和
+- gRPC TLS加密
+- 进程资源限制（内存/CPU）
+- 插件商店审核机制
+- 可信发布者白名单
+
+### 6. 配置系统
+
+**单一配置文件**: `config/plugins.yaml`
+
+```yaml
+# Tier 1: 编译时插件
+plugins:
+  hooks:
+    - name: web_search
+      enabled: false
+      priority: 50
+      config:
+        api_key: ${WEB_SEARCH_API_KEY}
+
+# Tier 2: 运行时插件（待实施）
+external_plugins:
+  enabled: true
+  hooks:
+    - name: awesome_hook
+      binary: awesome-hook-v1.0.0/awesome-hook
+      checksum: sha256:abc123...
+
+# 插件商店
+marketplace:
+  enabled: true
+  api_url: https://plugins.new-api.com
+```
+
+### 7. 性能对比
+
+| 场景 | Tier 1 | Tier 2 | RPC开销 |
+|------|--------|--------|--------|
+| 核心Channel | 100% | N/A | 0% |
+| 内置Hook | 100% | N/A | 0% |
+| 第三方Hook | N/A | 92-95% | 5-8% |
+| Python插件 | N/A | 88-92% | 8-12% |
+
+### 8. 实施路线图
+
+#### Phase 1: 编译时插件系统 ✅ 已完成
+- Core Registry + Hook Chain
+- 31个Channel插件 + 2个Hook示例
+- YAML配置系统
+
+#### Phase 2: go-plugin基础
+- protobuf协议定义
+- PluginLoader实现
+- 签名验证系统
+- Python/Go SDK
+
+#### Phase 3: 插件商店
+- 商店后端API
+- Web UI（搜索、安装、管理）
+- CLI工具
+- 多语言SDK
+
+### 9. 扩展示例
+
+**新增Tier 1插件（编译时）**:
+```go
+// 1. 实现接口
+type MyHook struct{}
+func (h *MyHook) OnBeforeRequest(ctx *HookContext) error { /*...*/ }
+
+// 2. 注册
