AutoGen实现多代理—AI Agentic Design Patterns with AutoGen（二）

1. AutoGen顺序对话在客户入职案例上的应用

在这里插入图片描述
如图，客户入职前会经历三个阶段，一个代理收集客户的信息，一个代理收集客户的感兴趣话题，一个代理根据前两个代理的基础信息与客户代理对话，产生聊天信息。

2. 代码实践

2.1 准备环境

llm_config={"model": "gpt-3.5-turbo"}from autogen import ConversableAgent

2.2 构建Agent

# 创建获取用户信息的Agent，包括名字和地址
onboarding_personal_information_agent = ConversableAgent(name="Onboarding Personal Information Agent",system_message='''You are a helpful customer onboarding agent,you are here to help new customers get started with our product.Your job is to gather customer's name and location.Do not ask for other information. Return 'TERMINATE' when you have gathered all the information.''',llm_config=llm_config,code_execution_config=False,human_input_mode="NEVER",
)

# 创建获取用户话题的Agent
onboarding_topic_preference_agent = ConversableAgent(name="Onboarding Topic preference Agent",system_message='''You are a helpful customer onboarding agent,you are here to help new customers get started with our product.Your job is to gather customer's preferences on news topics.Do not ask for other information.Return 'TERMINATE' when you have gathered all the information.''',llm_config=llm_config,code_execution_config=False,human_input_mode="NEVER",
)

# 创建与客户交互的Agent，基于客户提供的基础信息
customer_engagement_agent = ConversableAgent(name="Customer Engagement Agent",system_message='''You are a helpful customer service agenthere to provide fun for the customer based on the user'spersonal information and topic preferences.This could include fun facts, jokes, or interesting stories.Make sure to make it engaging and fun!Return 'TERMINATE' when you are done.''',llm_config=llm_config,code_execution_config=False,human_input_mode="NEVER",is_termination_msg=lambda msg: "terminate" in msg.get("content").lower(),
)

# 创建客户代理Agent
customer_proxy_agent = ConversableAgent(name="customer_proxy_agent",llm_config=False,code_execution_config=False,human_input_mode="ALWAYS",is_termination_msg=lambda msg: "terminate" in msg.get("content").lower(),
)

2.3 创建任务

现在，你可以制定一系列任务来促进新用户的入职流程。

chats = [{"sender": onboarding_personal_information_agent,"recipient": customer_proxy_agent,"message": "Hello, I'm here to help you get started with our product.""Could you tell me your name and location?","summary_method": "reflection_with_llm","summary_args": {"summary_prompt" : "Return the customer information ""into as JSON object only: ""{'name': '', 'location': ''}",},"max_turns": 2,"clear_history" : True},{"sender": onboarding_topic_preference_agent,"recipient": customer_proxy_agent,"message": "Great! Could you tell me what topics you are ""interested in reading about?","summary_method": "reflection_with_llm","max_turns": 1,"clear_history" : False},{"sender": customer_proxy_agent,"recipient": customer_engagement_agent,"message": "Let's find something fun to read.","max_turns": 1,"summary_method": "reflection_with_llm",},
]

2.4 开始对话

from autogen import initiate_chatschat_results = initiate_chats(chats)

执行阶段包含面板交互，提示输入用户的名字、地址和感兴趣的话题，输出如下：

********************************************************************************
Starting a new chat....********************************************************************************
Onboarding Personal Information Agent (to customer_proxy_agent):Hello, I'm here to help you get started with our product.Could you tell me your name and location?--------------------------------------------------------------------------------
Provide feedback to Onboarding Personal Information Agent. Press enter to skip and use auto-reply, or type 'exit' to end the conversation: Alice
customer_proxy_agent (to Onboarding Personal Information Agent):Alice--------------------------------------------------------------------------------
Onboarding Personal Information Agent (to customer_proxy_agent):Thank you, Alice. Could you also let me know your location, please?--------------------------------------------------------------------------------

}

2.5 打印摘要

for chat_result in chat_results:print(chat_result.summary)print("\n")

输出如下：

{"name": "Alice","location": "New York"
}Alice is interested in reading about dogs.Alice from New York is interested in reading about dogs. She is about to dive into the wonderful world of dogs, learning about the world's oldest known breed, the Saluki, and the joy and love that dogs bring into our lives.
