3. 智能体创建实战：打造专属AI助手

3.1 基础智能体构建

from modelengine.agent import AgentBuilder
from modelengine.memory import ConversationMemory
from modelengine.tools import WebSearch, Calculator, FileProcessor

# 创建智能体构建器
builder = AgentBuilder()

# 定义智能体角色
agent = builder.create_agent(
    name="技术顾问助手",
    role="专业的AI技术顾问，擅长解答编程和技术架构问题",
    capabilities=["code_generation", "problem_solving", "architect_design"]

)

# 保存智能体配置
agent_config = agent.export_config()
with open("tech_advisor_agent.json", "w") as f:
    f.write(agent_config)

3.2 智能体调试控制台

// 智能体调试界面示例代码
class AgentDebugger {
  constructor(agentId) {
    this.agentId = agentId;
    this.sessionId = this.generateSessionId();
  }
  
  async sendMessage(message) {
    const response = await fetch('/api/agent/chat', {
      method: 'POST',
      headers: {'Content-Type': 'application/json'},
      body: JSON.stringify({
        agent_id: this.agentId,
        session_id: this.sessionId,
        message: message,
        debug: true  // 启用调试模式
      })
    });
    
    const result = await response.json();
    
    // 显示调试信息
    this.displayDebugInfo(result.debug);
    return result.response;
  }
  
  displayDebugInfo(debugData) {
    console.log("思维链:", debugData.chain_of_thought);
    console.log("使用的工具:", debugData.tools_used);
    console.log("置信度:", debugData.confidence);
    console.log("处理时间:", debugData.processing_time + "ms");
  }
}

4. 知识库智能管理：文档自动总结与检索优化

4.1 知识库自动构建

from modelengine.knowledge import KnowledgeBase
from modelengine.processors import DocumentProcessor

# 初始化知识库
kb = KnowledgeBase(
    name="企业技术文档",
    embedding_model="text-embedding-v1"
)

# 文档自动处理流水线
processor = DocumentProcessor()

# 支持多种文档格式
documents = processor.process_directory(
    path="./documents/",
    file_types=[".pdf", ".docx", ".md", ".html"],
    chunk_size=500,
    overlap=50
)

# 智能文档总结
for doc in documents:
    # 自动生成摘要
    summary = processor.generate_summary(
        text=doc.content,
        max_length=200
    )
    
    # 提取关键词
    keywords = processor.extract_keywords(
        text=doc.content,
        top_k=10
    )
    
    # 添加到知识库
    kb.add_document(
        content=doc.content,
        metadata={
            "title": doc.metadata.get("title", ""),
            "summary": summary,
            "keywords": keywords,
            "source": doc.metadata.get("source", "")
        }
    )

    "strategy": "hybrid",
    "embedding_weight": 0.7,
    "keyword_weight": 0.3,
    "reranker": "bge-reranker-large",
    "max_results": 5,
    "score_threshold": 0.65
}

# 智能查询增强
def enhanced_retrieval(query, context=None):
    # 查询扩展
    expanded_queries = query_expander.expand(query)
    
    # 多路检索
    results = []
    for expanded_query in expanded_queries:
        # 向量检索
        vector_results = kb.vector_search(
            query=expanded_query,
            top_k=3
        )
        
        # 关键词检索
        keyword_results = kb.keyword_search(
            query=expanded_query,
            top_k=3
        )
        
        # 结果融合与重排序
        merged = result_merger.merge(
            [vector_results, keyword_results],
            weights=[0.7, 0.3]
        )
        
        results.extend(merged)
    
    # 去重与排序
    final_results = reranker.rerank(
        query=query,
        documents=results,
        context=context
    )
    
    return final_results[:retrieval_config["max_results"]]
