We learn to use multi-agent systems through a case study of a "Philosopher Chat Room," where we construct philosophical thoughts and discussions on a question from Confucius, Socrates, and Aristotle.
Creating Agents#
We implement a Philosopher class that inherits from the BaseAgent base class. The constructor receives parameters such as the philosopher's name and language model, setting role prompts to allow the AI to play the role of a specific philosopher. Each philosopher agent has its own name and role positioning, using the same language model (llm) to express opinions based on their philosophical thoughts. This design allows us to simulate dialogues and exchanges of ideas among different philosophers:
from typing import List
from zigent.actions.BaseAction import BaseAction
from zigent.agents import ABCAgent, BaseAgent
# Define the Philosopher class, inheriting from the BaseAgent class
class Philosopher(BaseAgent):
def __init__(
self,
philosopher,
llm: LLM,
actions: List[BaseAction] = [],
manager: ABCAgent = None,
**kwargs
):
name = philosopher
# Role
role = f"""You are {philosopher}, the famous educator in history. You are very familiar with {philosopher}'s Book and Thought. Tell your opinion on behalf of {philosopher}."""
super().__init__(
name=name,
role=role,
llm=llm,
actions=actions,
manager=manager
)
# Initialize philosopher objects
Confucius = Philosopher(philosopher= "Confucius", llm = llm) # Confucius
Socrates = Philosopher(philosopher="Socrates", llm = llm) # Socrates
Aristotle = Philosopher(philosopher="Aristotle", llm = llm) # Aristotle
Arranging Actions#
We set up the "example task" for the philosopher agents through action arrangement, aiming to help the Agent better understand how to answer questions. This mainly includes setting example questions, defining the thinking process, and applying it to all philosophers. We established a "think first, summarize later" response pattern, which effectively provides the AI with a "template," telling it: "This is how we expect you to answer questions":
# Import necessary modules
from zigent.commons import AgentAct, TaskPackage
from zigent.actions import ThinkAct, FinishAct
from zigent.actions.InnerActions import INNER_ACT_KEY
from zigent.agents.agent_utils import AGENT_CALL_ARG_KEY
# Add example tasks for the philosopher agents
# Set example task: asking about the meaning of life
exp_task = "What do you think the meaning of life?"
exp_task_pack = TaskPackage(instruction=exp_task)
# First action: think about the meaning of life
act_1 = AgentAct(
name=ThinkAct.action_name,
params={INNER_ACT_KEY: f"""Based on my thought, we are born to live a meaningful life, and it is in living a meaningful life that our existence gains value. Even if a life is brief, if it holds value, it is meaningful. A life without value is merely existence, a mere survival, a walking corpse."""
},
)
# Observation result of the first action
obs_1 = "OK. I have finished my thought, I can pass it to the manager now."
# Second action: summarize the thinking results
act_2 = AgentAct(name=FinishAct.action_name, params={INNER_ACT_KEY: "I can summarize my thought now."})
# Observation result of the second action
obs_2 = "I finished my task, I think the meaning of life is to pursue value for the whole world."
# Combine actions and observations into a sequence
exp_act_obs = [(act_1, obs_1), (act_2, obs_2)]
# Add examples for each philosopher agent
# Add example for Confucius
Confucius.prompt_gen.add_example(
task = exp_task_pack, action_chain = exp_act_obs
)
# Add example for Socrates
Socrates.prompt_gen.add_example(
task = exp_task_pack, action_chain = exp_act_obs
)
# Add example for Aristotle
Aristotle.prompt_gen.add_example(
task = exp_task_pack, action_chain = exp_act_obs
)
Defining ManagerAgent#
Next, we implement a manager agent in the multi-agent system responsible for coordinating the three philosophers: Confucius, Socrates, and Aristotle. The manager's role is defined as: to sequentially ask each philosopher for their views and summarize them. The ManagerAgent sets up the example task flow of "What is the meaning of life?" which includes steps like thinking about how to handle the task, asking the philosophers for their views, and summarizing the views:
# Define the manager agent
from zigent.agents import ManagerAgent
# Set the basic information for the manager agent
manager_agent_info = {
"name": "manager_agent",
"role": "you are managing Confucius, Socrates and Aristotle to discuss on questions. Ask their opinion one by one and summarize their view of point."
}
# Set team members
team = [Confucius, Socrates, Aristotle]
# Create an instance of the manager agent
manager_agent = ManagerAgent(name=manager_agent_info["name"], role=manager_agent_info["role"], llm=llm, TeamAgents=team)
# Add example tasks for the manager agent
exp_task = "What is the meaning of life?"
exp_task_pack = TaskPackage(instruction=exp_task)
# Step one: think about how to handle the task
act_1 = AgentAct(
name=ThinkAct.action_name,
params={INNER_ACT_KEY: f"""I can ask Confucius, Socrates and Aristotle one by one on their thoughts, and then summarize the opinion myself."""
},
)
obs_1 = "OK."
# Step two: ask Confucius for his view
act_2 = AgentAct(
name=Confucius.name,
params={AGENT_CALL_ARG_KEY: "What is your opinion on the meaning of life?",
},
)
obs_2 = """Based on my thought, I think the meaning of life is to pursue value for the whole world."""
# Step three: think about the next action
act_3 = AgentAct(
name=ThinkAct.action_name,
params={INNER_ACT_KEY: f"""I have obtained information from Confucius, I need to collect more information from Socrates."""
},
)
obs_3 = "OK."
# Step four: ask Socrates for his view
act_4 = AgentAct(
name=Socrates.name,
params={AGENT_CALL_ARG_KEY: "What is your opinion on the meaning of life?",
},
)
obs_4 = """I think the meaning of life is finding happiness."""
# Step five: continue thinking about the next step
act_5 = AgentAct(
name=ThinkAct.action_name,
params={INNER_ACT_KEY: f"""I have obtained information from Confucius and Socrates, I can collect more information from Aristotle."""
},
)
obs_5 = "OK."
# Step six: ask Aristotle for his view
act_6 = AgentAct(
name=Aristotle.name,
params={AGENT_CALL_ARG_KEY: "What is your opinion on the meaning of life?",
},
)
obs_6 = """I believe the freedom of spirit is the meaning."""
# Final step: summarize all views
act_7 = AgentAct(name=FinishAct.action_name, params={INNER_ACT_KEY: "Their thought on the meaning of life is to pursue value, happiness and freedom of spirit."})
obs_7 = "Task Completed. The meaning of life is to pursue value, happiness and freedom of spirit."
# Combine all actions and observations into a sequence
exp_act_obs = [(act_1, obs_1), (act_2, obs_2), (act_3, obs_3), (act_4, obs_4), (act_5, obs_5), (act_6, obs_6), (act_7, obs_7)]
# Add examples to the manager agent's prompt generator
manager_agent.prompt_gen.add_example(
task = exp_task_pack, action_chain = exp_act_obs
)
Calling ManagerAgent#
Finally, we call this manager Agent, which will handle new tasks based on the example tasks and action sequences we set up earlier. In this example, we set a new task "Which came first, the chicken or the egg?" and then call the manager Agent to handle this task:
from zigent.commons import AgentAct, TaskPackage
exp_task = "Which came first, the chicken or the egg?"
exp_task_pack = TaskPackage(instruction=exp_task)
manager_agent(exp_task_pack)
The process is as follows:
