2ProductionAgent — 生产级一行调用接口。 

3 

4将 LLM Provider → ToolExecutor → Bridge → BaseTool/Skill 全链路封装， 

5提供结构化日志、结果统计，开箱即用。 

6 

7用法: 

8 from agentos.agent.production_agent import ProductionAgent 

9 

10 agent = ProductionAgent() 

11 result = agent.run("分析我的 CSV 文件 sales.csv") 

12 

13 print(result.output) 

14 print(f"{result.total_steps} steps, {result.total_latency_ms:.0f}ms")
