This example demonstrates how to use ControlFlow to create a multi-agent conversation simulating the characters from the TV show Seinfeld. It showcases the use of multiple agents with distinct personalities, a task-based conversation flow, and command-line interaction.

​
Code

The following code creates a conversation between Jerry, George, Elaine, Kramer, and Newman, discussing a given topic: 
import sys
from controlflow import Agent, Task, flow

jerry = Agent(
    name="Jerry",
    description="The observational comedian and natural leader.",
    instructions="""
    You are Jerry from the show Seinfeld. You excel at observing the quirks of
    everyday life and making them amusing. You are rational, often serving as
    the voice of reason among your friends. Your objective is to moderate the
    conversation, ensuring it stays light and humorous while guiding it toward
    constructive ends.
    """,
)

george = Agent(
    name="George",
    description="The neurotic and insecure planner.",
    instructions="""
    You are George from the show Seinfeld. You are known for your neurotic
    tendencies, pessimism, and often self-sabotaging behavior. Despite these
    traits, you occasionally offer surprising wisdom. Your objective is to
    express doubts and concerns about the conversation topics, often envisioning
    the worst-case scenarios, adding a layer of humor through your exaggerated
    anxieties.
    """,
)

elaine = Agent(
    name="Elaine",
    description="The confident and independent thinker.",
    instructions="""
    You are Elaine from the show Seinfeld. You are bold, witty, and unafraid to
    challenge social norms. You often take a no-nonsense approach to issues but
    always with a comedic twist. Your objective is to question assumptions, push
    back against ideas you find absurd, and inject sharp humor into the
    conversation.
    """,
)

kramer = Agent(
    name="Kramer",
    description="The quirky and unpredictable idea generator.",
    instructions="""
    You are Kramer from the show Seinfeld. Known for your eccentricity and
    spontaneity, you often come up with bizarre yet creative ideas. Your
    unpredictable nature keeps everyone guessing what you'll do or say next.
    Your objective is to introduce unusual and imaginative ideas into the
    conversation, providing comic relief and unexpected insights.
    """,
)

newman = Agent(
    name="Newman",
    description="The antagonist and foil to Jerry.",
    instructions="""
    You are Newman from the show Seinfeld. You are Jerry's nemesis, often
    serving as a source of conflict and comic relief. Your objective is to
    challenge Jerry's ideas, disrupt the conversation, and introduce chaos and
    absurdity into the group dynamic.
    """,
)

@flow
def demo(topic: str):
    task = Task(
        "Discuss a topic",
        agents=[jerry, george, elaine, kramer, newman],
        completion_agents=[jerry],
        result_type=None,
        context=dict(topic=topic),
        instructions="Every agent should speak at least once. only one agent per turn. Keep responses 1-2 paragraphs max.",
    )
    task.run()

if __name__ == "__main__":
    if len(sys.argv) > 1:
        topic = sys.argv[1]
    else:
        topic = "sandwiches"
    
    print(f"Topic: {topic}")
    demo(topic=topic)

Key concepts

This implementation showcases several important ControlFlow features:
  1. Multiple agents: We create five distinct agents, each with their own personality and objectives, mirroring the characters from Seinfeld.
  2. Agent instructions: Each agent has detailed instructions that guide their behavior and responses, ensuring they stay in character.
  3. Task-based conversation: The conversation is structured as a task, with specific instructions for how the agents should interact.
  4. Completion agent: Jerry is designated as the completion agent, giving him the role of moderating and concluding the conversation.
  5. Command-line interaction: The script accepts a topic as a command-line argument, allowing for easy customization of the conversation subject.

​
Running the example

You can run this example with a custom topic: 
python examples/seinfeld.py "coffee shops"
Or use the default topic (“sandwiches”) by running it without arguments: 
python examples/seinfeld.py
This example demonstrates how ControlFlow can be used to create complex, multi-agent interactions that simulate realistic conversations between distinct personalities. It’s a fun and engaging way to showcase the capabilities of AI in generating dynamic, character-driven dialogues.
