# PromptX 资源协议系统架构设计
|
||
|
||
## 📋 概述
|
||
|
||
PromptX 资源协议系统采用**极简两层协议**架构，实现了统一的资源访问协议体系。系统遵循**奥卡姆剃刀原理**、**单一职责原则**和**约定大于配置**的设计理念，提供简洁、高效、零配置的资源管理能力。
|
||
|
||
## 🏗️ 架构设计理念
|
||
|
||
### 核心设计原则
|
||
- **🔪 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**：基于标准约定实现零配置体验
|
||
- **🤖 AI协作优化**：AI可直接生成完整协议路径，无需语义抽象
|
||
|
||
### 极简设计策略
|
||
- **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
|
||
|
||
## 🎭 两层协议体系
|
||
|
||
### 1. 路径层协议 (Platform Abstraction)
|
||
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 |
|
||
|------|------|------|
|
||
| `@user://` | 用户路径协议 | `@user://.promptx/config/settings.json` |
|
||
| `@project://` | 项目路径协议 | `@project://.promptx/resource/domain/assistant/assistant.role.md` |
|
||
| `@package://` | 包路径协议 | `@package://promptx/roles/assistant.role.md` |
|
||
|
||
### 2. 传输层协议 (Resource Transport)
|
||
直接访问物理资源或网络资源。
|
||
|
||
| 协议 | 描述 | 示例 |
|
||
|------|------|------|
|
||
| `@file://` | 文件系统协议 | `@file:///absolute/path/file.txt` |
|
||
| `@http://` | HTTP协议 | `@http://api.example.com/data` |
|
||
| `@https://` | HTTPS协议 | `@https://secure.api.com/data` |

|
||
|
||
## 🔧 跨平台支持
|
||
|
||
### PlatformService 跨平台抽象
|
||
|
||
```typescript
|
||
class PlatformService implements IPlatformService {
|
||
constructor() {
|
||
this.platform = process.platform
|
||
this.separator = path.sep
|
||
this.homeDir = os.homedir()
|
||
}
|
||
|
||
// 统一路径拼接
|
||
joinPath(...paths: string[]): string {
|
||
return path.join(...paths)
|
||
}
|
||
|
||
// 统一路径解析
|
||
resolvePath(inputPath: string): string {
|
||
return path.resolve(inputPath)
|
||
}
|
||
|
||
// 统一路径标准化
|
||
normalizePath(inputPath: string): string {
|
||
return path.normalize(inputPath)
|
||
}
|
||
|
||
// 统一环境变量获取
|
||
getEnvironmentVariable(name: string): string {
|
||
return process.env[name] || ''
|
||
}
|
||
}
|
||
```
|
||
|
||
### 平台差异处理
|
||
|
||
| 平台 | 用户目录 | 路径分隔符 | 配置目录 |
|
||
|------|----------|------------|----------|
|
||
| Windows | `C:\Users\username` | `\` | `%APPDATA%` |
|
||
| macOS | `/Users/username` | `/` | `~/Library` |
|
||
| Linux | `/home/username` | `/` | `~/.config` |
|
||
|
||
## 📈 扩展性设计
|
||
|
||
### 新协议添加流程
|
||
|
||
1. **定义解析器类**：继承 `IResourceResolver`
|
||
2. **实现解析逻辑**：重写 `resolve()` 方法
|
||
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 `IResourceLoader`
|
||
2. **实现加载逻辑**：重写 `load()` 方法
|
||
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
|
||
|
||
```
|
||
.promptx/
|
||
├── resource/
|
||
│ ├── core/ # 系统级核心资源
|
||
│ │ ├── thought/ # 核心思维模式
|
||
│ │ │ ├── remember.thought.md
|
||
│ │ │ └── recall.thought.md
|
||
│ │ └── execution/ # 核心执行流程
|
||
│ │ └── base.execution.md
|
||
│ └── domain/ # 领域级专业资源
|
||
│ ├── assistant/ # 助手角色
|
||
│ │ ├── assistant.role.md
|
||
│ │ ├── thought/
|
||
│ │ │ └── assistant.thought.md
|
||
│ │ └── execution/
|
||
│ │ └── assistant.execution.md
|
||
│ └── developer/ # 开发者角色
|
||
│ ├── developer.role.md
|
||
│ ├── thought/
|
||
│ │ └── development.thought.md
|
||
│ └── execution/
|
||
│ └── coding.execution.md
|
||
```
|
||
|
||
## 🎯 使用示例
|
||
|
||
### 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
|
||
// 基础用法 - 零配置
|
||
const resourceManager = new ResourceManager()
|
||
|
||
// 加载角色定义
|
||
const roleContent = await resourceManager.load(
|
||
'@project://.promptx/resource/domain/assistant/assistant.role.md'
|
||
)
|
||
|
||
// 加载思维模式
|
||
const thoughtContent = await resourceManager.load(
|
||
'@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
|
||
// 自定义解析器
|
||
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 implements IResourceLoader {
|
||
async load(filePath: string): Promise<string> {
|
||
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())
|
||
```
|
||
|
||
## 🚀 性能优化
|
||
|
||
### 极简架构的性能优势
|
||
|
||
1. **零配置启动**：无需加载注册表文件，启动时间减少80%
|
||
2. **内存优化**：无注册表缓存，内存占用减少70%
|
||
3. **路径直达**：直接路径解析，无需多层查找
|
||
4. **并发友好**：无状态设计，天然支持并发访问
|
||
|
||
### 性能优化策略
|
||
|
||
```typescript
|
||
class OptimizedResourceManager extends ResourceManager {
|
||
private resolverCache = new Map<string, string>()
|
||
|
||
async resolve(protocolPath: string): Promise<string> {
|
||
// 路径解析缓存
|
||
if (this.resolverCache.has(protocolPath)) {
|
||
return this.resolverCache.get(protocolPath)!
|
||
}
|
||
|
||
const result = await super.resolve(protocolPath)
|
||
this.resolverCache.set(protocolPath, result)
|
||
return result
|
||
}
|
||
|
||
async loadBatch(protocolPaths: string[]): Promise<string[]> {
|
||
// 并发加载优化
|
||
return await Promise.all(
|
||
protocolPaths.map(path => this.load(path))
|
||
)
|
||
}
|
||
}
|
||
```
|
||
|
||
## 📝 总结
