DeepTutor是一款基于多智能体架构的个性化学习助手，其强大的插件系统让开发者能够轻松扩展AI学习功能。本教程将详细介绍如何开发DeepTutor插件，从理解核心架构到实现自定义能力，帮助您快速上手插件开发。

🏗️ DeepTutor插件系统架构概览

DeepTutor采用分层架构设计，插件系统位于核心能力层。系统通过能力注册机制管理所有功能模块，包括内置能力和插件扩展能力。

核心组件解析

DeepTutor的插件系统围绕以下几个核心组件构建：

能力协议层 (deeptutor/core/capability_protocol.py) - 定义插件接口规范
能力注册表 (deeptutor/runtime/registry/capability_registry.py) - 管理插件注册和发现
内置能力 (deeptutor/runtime/bootstrap/builtin_capabilities.py) - 系统预置功能模块
API路由层 (deeptutor/api/routers/plugins_api.py) - 提供插件管理接口

📦 插件开发基础：创建第一个DeepTutor插件

步骤1：理解能力协议

所有DeepTutor插件都必须继承BaseCapability基类，并实现run方法。以下是基本结构：

from deeptutor.core.capability_protocol import BaseCapability, CapabilityManifest
from deeptutor.core.context import UnifiedContext
from deeptutor.core.stream_bus import StreamBus

class MyCustomCapability(BaseCapability):
    manifest = CapabilityManifest(
        name="my_custom_plugin",
        description="我的自定义插件描述",
        stages=["stage1", "stage2", "stage3"],
        tools_used=["rag", "web_search"],
        cli_aliases=["myplugin"],
    )
    
    async def run(self, context: UnifiedContext, stream: StreamBus) -> None:
        # 插件逻辑实现
        async with stream.stage("stage1", source=self.manifest.name):
            # 第一阶段处理
            pass
        # ... 更多阶段

步骤2：查看内置能力示例

DeepTutor提供了多个内置能力作为开发参考：

深度解题能力 (deeptutor/capabilities/deep_solve.py) - 多智能体问题求解
深度问答能力 (deeptutor/capabilities/deep_question.py) - 智能问答生成
深度研究能力 (deeptutor/capabilities/deep_research.py) - 研究分析功能
数学动画能力 (deeptutor/capabilities/math_animator.py) - 数学可视化

步骤3：插件注册机制

插件通过CapabilityRegistry自动注册。系统启动时会扫描并加载所有插件：

# 能力注册表示例
class CapabilityRegistry:
    def __init__(self) -> None:
        self._capabilities: dict[str, BaseCapability] = {}
    
    def register(self, capability: BaseCapability) -> None:
        self._capabilities[capability.name] = capability
    
    def load_plugins(self) -> None:
        # 自动发现并加载插件
        for manifest in discover_plugins():
            capability = load_plugin_capability(manifest)
            self.register(capability)

🔧 插件开发实战：创建学习进度追踪插件

项目结构规划

my_learning_tracker/
├── __init__.py
├── capability.py          # 插件主类
├── manifest.yaml         # 插件元数据
├── agents/              # 智能体模块
│   ├── progress_agent.py
│   └── analysis_agent.py
└── tools/               # 工具模块
    └── progress_tool.py

核心代码实现

# capability.py
from deeptutor.core.capability_protocol import BaseCapability, CapabilityManifest
from deeptutor.core.context import UnifiedContext
from deeptutor.core.stream_bus import StreamBus

class LearningTrackerCapability(BaseCapability):
    manifest = CapabilityManifest(
        name="learning_tracker",
        description="学习进度追踪与分析插件",
        stages=["收集数据", "分析进度", "生成报告", "提供建议"],
        tools_used=["rag", "code_execution"],
        cli_aliases=["track"],
        request_schema={
            "type": "object",
            "properties": {
                "student_id": {"type": "string"},
                "course_name": {"type": "string"},
                "time_range": {"type": "string"}
            }
        }
    )
    
    async def run(self, context: UnifiedContext, stream: StreamBus) -> None:
        # 实现四个阶段的学习追踪流程
        async with stream.stage("收集数据", source=self.manifest.name):
            data = await self._collect_learning_data(context)
            
        async with stream.stage("分析进度", source=self.manifest.name):
            analysis = await self._analyze_progress(data)
            
        async with stream.stage("生成报告", source=self.manifest.name):
            report = await self._generate_report(analysis)
            
        async with stream.stage("提供建议", source=self.manifest.name):
            suggestions = await self._provide_suggestions(report)
            
        await stream.final_output(suggestions)

插件配置与集成

配置文件示例 (manifest.yaml):

name: learning_tracker
version: 1.0.0
description: 学习进度追踪插件
entry_point: my_learning_tracker.capability:LearningTrackerCapability
dependencies:
  - pandas>=2.0.0
  - matplotlib>=3.7.0

安装与激活:

# 将插件目录复制到DeepTutor插件目录
cp -r my_learning_tracker /path/to/deeptutor/plugins/

# 重启DeepTutor服务
python -m deeptutor.api.main

🚀 高级插件开发技巧

技巧1：利用现有工具链

DeepTutor提供了丰富的内置工具，插件可以直接调用：

# 使用RAG工具进行知识检索
from deeptutor.tools.rag_tool import RAGTool

rag = RAGTool()
results = await rag.search(context.query, limit=5)

# 使用代码执行工具
from deeptutor.tools.code_executor import CodeExecutor
executor = CodeExecutor()
output = await executor.execute(code="print('Hello, World!')")

技巧2：多阶段流程设计

遵循DeepTutor的多阶段设计模式，将复杂任务分解为多个可管理的阶段：

async def run(self, context: UnifiedContext, stream: StreamBus) -> None:
    # 阶段1：数据准备
    async with stream.stage("数据准备", source=self.name):
        prepared_data = await self._prepare_data(context)
    
    # 阶段2：智能分析  
    async with stream.stage("智能分析", source=self.name):
        analysis_result = await self._analyze_data(prepared_data)
    
    # 阶段3：结果生成
    async with stream.stage("结果生成", source=self.name):
        final_result = await self._generate_output(analysis_result)
    
    # 阶段4：反馈优化
    async with stream.stage("反馈优化", source=self.name):
        optimized = await self._optimize_with_feedback(final_result)
    
    await stream.final_output(optimized)

技巧3：与Web界面集成

插件可以通过Web界面与用户交互：

配置前端路由 - 在Web应用中添加插件相关页面
API端点集成 - 通过REST API暴露插件功能
实时通信 - 使用WebSocket推送进度更新

🧪 插件测试与调试

单元测试示例

# test_my_plugin.py
import pytest
from deeptutor.core.context import UnifiedContext
from my_learning_tracker.capability import LearningTrackerCapability

@pytest.mark.asyncio
async def test_learning_tracker_basic():
    capability = LearningTrackerCapability()
    context = UnifiedContext(
        query="测试学习进度追踪",
        config_overrides={"detailed_answer": True}
    )
    
    # 模拟运行
    result = await capability._collect_learning_data(context)
    assert result is not None
    assert "progress_data" in result
