 ## 🏗️ 架构设计理念
 
 ### 核心设计原则
-- **🔪 奥卡姆剃刀原理**：追求最简洁有效的解决方案，去除不必要的复杂性
+- **🔪 奥卡姆剃刀原理**：删除不必要的抽象层，追求最简洁有效的解决方案
 - **🎯 单一职责原则**：每个组件只负责一个明确的职责，避免功能混杂
-- **⚙️ 约定大于配置**：优先使用智能约定减少用户配置，提供零配置体验
+- **⚙️ 约定大于配置**：基于标准约定实现零配置体验
-- **🔄 装饰器模式**：层次化装饰，功能逐步增强，灵活可组合
+- **🤖 AI协作优化**：AI可直接生成完整协议路径，无需语义抽象
 
-### MVP 设计策略
+### 极简设计策略
-- **专注核心功能**：去除缓存、复杂验证等非核心功能
+- **删除语义层协议**：AI直接使用完整路径，无需 `@role://` 等语义抽象
+- **删除注册表机制**：基于约定的目录结构，无需维护映射关系
+- **专注核心功能**：只保留路径解析和内容加载的核心能力
 - **渐进式扩展**：架构支持后续功能的平滑增加
-- **跨平台优先**：统一处理 Windows、macOS、Linux 平台差异
 
-## 🎭 三层协议体系
+## 🎭 两层协议体系
 
-### 1. 语义层协议 (AI功能协议)
+### 1. 路径层协议 (Platform Abstraction)
-负责AI功能的语义抽象，通过注册表查找实际资源路径。
+提供跨平台的路径抽象，统一处理不同操作系统的路径差异。
 
 | 协议 | 描述 | 示例 |
 |------|------|------|
-| `@role://` | AI角色定义协议 | `@role://product-manager` |

+| `@package://` | 包路径协议 | `@package://promptx/roles/assistant.role.md` |
-| `@knowledge://` | 知识体系协议 | `@knowledge://javascript` |
 
-### 2. 路径层协议 (路径抽象协议)
+### 2. 传输层协议 (Resource Transport)
-提供跨平台的路径抽象，直接进行路径转换。

-## 🔍 注册表协议引用机制
-
-### 注册表结构说明
-
-PromptX 的注册表本身也使用协议引用，而不是直接存储物理路径：
-
-```json
-{
-  "id": "promptx-architect",
-  "source": "project", 
-  "protocol": "role",
-  "name": "Promptx Architect 角色",
-  "reference": "@project://.promptx/resource/domain/promptx-architect/promptx-architect.role.md"
-}
-```
-
-### 二次协议解析流程
-
-语义层协议的解析需要经过两个步骤：
-
-1. **第一次解析**：`@role://promptx-architect` → 查找注册表 → `@project://...`
-2. **第二次解析**：`@project://...` → 路径层解析器 → 物理文件路径
-
-这种设计的优势：
-- **🔄 协议一致性**：注册表也遵循统一的协议语法
-- **🎯 灵活性**：资源可以存储在不同的位置（用户、项目、包等）
-- **🔧 可维护性**：修改资源位置只需更新注册表，不影响引用方
-- **📈 扩展性**：支持跨项目、跨用户的资源引用

 ### 新协议添加流程
 
-1. **定义协议类**：继承 `ResourceProtocol`
+1. **定义解析器类**：继承 `IResourceResolver`
-2. **实现解析器**：继承 `ResourceResolver`
+2. **实现解析逻辑**：重写 `resolve()` 方法
-3. **注册协议**：添加到协议注册表
+3. **注册解析器**：添加到ResourceManager
 4. **测试验证**：编写单元测试
 
+```typescript
+// 示例：添加S3协议支持
+class S3Resolver implements IResourceResolver {
+  async resolve(protocolPath: string): Promise<string> {
+    // @s3://bucket/key → s3://bucket/key
+    return protocolPath.replace('@s3://', 's3://')
+  }
+  
+  canResolve(protocol: string): boolean {
+    return protocol === 's3'
+  }
+}
+
+// 注册新协议
+resourceManager.registerResolver('s3', new S3Resolver())
+```
+
 ### 新加载器添加流程
 
-1. **定义加载器类**：继承 `ResourceLoader`
+1. **定义加载器类**：继承 `IResourceLoader`
 2. **实现加载逻辑**：重写 `load()` 方法
-3. **注册加载器**：添加到加载器工厂
+3. **注册加载器**：添加到ResourceManager
 4. **测试验证**：编写单元测试
 
+```typescript
+// 示例：添加YAML加载器
+class YamlLoader implements IResourceLoader {
+  async load(filePath: string): Promise<string> {
+    const buffer = await fs.readFile(filePath)
+    const yamlData = yaml.parse(buffer.toString())
+    return JSON.stringify(yamlData, null, 2)
+  }
+  
+  canLoad(filePath: string): boolean {
+    return filePath.endsWith('.yml') || filePath.endsWith('.yaml')
+  }
+}
+
+// 注册新加载器
+resourceManager.registerLoader(new YamlLoader())
+```
+
+## 🎯 标准约定体系
+
+### AI生成的标准路径模式
+
+```typescript
+// AI遵循的标准约定
+const STANDARD_CONVENTIONS = {
+  // 核心思维能力（系统级）
+  coreThoughts: '@project://.promptx/resource/core/thought/{name}.thought.md',
+  
+  // 角色专用思维（领域级）  
+  roleThoughts: '@project://.promptx/resource/domain/{role}/thought/{name}.thought.md',
+  
+  // 执行流程（领域级）
+  executions: '@project://.promptx/resource/domain/{role}/execution/{name}.execution.md',
+  
+  // 知识体系（领域级）
+  knowledge: '@project://.promptx/resource/domain/{role}/knowledge/{name}.knowledge.md',
+  
+  // 角色定义（领域级）
+  roles: '@project://.promptx/resource/domain/{role}/{role}.role.md'
+}
+```
+
+### 标准约定目录结构

 ## 🎯 使用示例
 
-### 基础用法
+### AI直接生成完整路径
+
+```xml
+<!-- AI生成的DPML - 使用完整协议路径 -->
+<role>
+  <personality>
+    @!project://.promptx/resource/core/thought/remember.thought.md
+    @!project://.promptx/resource/core/thought/recall.thought.md
+    @!project://.promptx/resource/domain/assistant/thought/assistant.thought.md
+  </personality>
+  
+  <principle>
+    @!project://.promptx/resource/domain/assistant/execution/assistant.execution.md
+  </principle>
+  
+  <knowledge>
+    @!project://.promptx/resource/domain/assistant/knowledge/general.knowledge.md
+  </knowledge>
+</role>
+```
+
+### 程序化使用
 
 ```typescript
-// 语义层协议使用
+// 基础用法 - 零配置
-const roleContent = await resourceSystem.load('@role://product-manager')
+const resourceManager = new ResourceManager()
-const thoughtContent = await resourceSystem.load('@thought://creativity')
 
-// 路径层协议使用
+// 加载角色定义
-const userConfig = await resourceSystem.load('@user://config/settings.json')
+const roleContent = await resourceManager.load(
-const projectFile = await resourceSystem.load('@project://src/index.js')
+  '@project://.promptx/resource/domain/assistant/assistant.role.md'
+)
 
-// 传输层协议使用
+// 加载思维模式
-const localFile = await resourceSystem.load('@file:///path/to/file.txt')
+const thoughtContent = await resourceManager.load(
-const remoteData = await resourceSystem.load('@https://api.example.com/data')
+  '@project://.promptx/resource/core/thought/remember.thought.md'
+)
+
+// 检查资源存在性
+const exists = await resourceManager.exists(
+  '@user://.promptx/config/settings.json'
+)
+
+// 只解析路径不加载内容
+const physicalPath = await resourceManager.resolve(
+  '@project://.promptx/resource/domain/assistant/assistant.role.md'
+)
 ```
 
 ### 高级用法
 
 ```typescript
-// 协议验证
-const isValid = RoleProtocol.validatePath('@role://invalid-name')
-
 // 自定义解析器
-class CustomResolver extends ResourceResolver {
+class CustomResolver implements IResourceResolver {
   async resolve(protocolPath: string): Promise<string> {
     // 自定义解析逻辑
     return this.customResolveLogic(protocolPath)
   }
+  
+  canResolve(protocol: string): boolean {
+    return protocol === 'custom'
+  }
 }
 
 // 自定义加载器
-class XmlLoader extends ResourceLoader {
+class XmlLoader implements IResourceLoader {
   async load(filePath: string): Promise<string> {
-    const buffer = await this.readFile(filePath)
+    const buffer = await fs.readFile(filePath)
     return this.parseXmlContent(buffer)
   }
+  
+  canLoad(filePath: string): boolean {
+    return filePath.endsWith('.xml')
+  }
 }
+
+// 注册扩展
+resourceManager.registerResolver('custom', new CustomResolver())
+resourceManager.registerLoader(new XmlLoader())
 ```

+    }
+    
+    const result = await super.resolve(protocolPath)
