Abstract

This research proposes a lightweight autonomous agent framework based on the ReAct paradigm, designed to solve complex tasks through adaptive decision-making and multi-agent collaboration. Unlike traditional frameworks that rely on fixed workflows generated by an LLM-based scheduler, this framework dynamically generates next actions during agent execution based on prior trajectories, which enhances their robustness. To address potential termination issues caused by adaptive execution paths, I propose a timely abandonment strategy with a probabilistic penalty mechanism. For multi-agent collaboration, I introduce a memory transfer mechanism that enables shared and dynamically updated memory among agents. The framework’s innovative timely abandonment strategy dynamically adjusts the probability of task abandonment via probabilistic penalties, allowing developers to balance conservative and exploratory tendencies in agent execution strategies by tuning hyperparameters. This significantly improves adaptability and task efficiency in complex environments. Additionally, agents can be expanded through external tool use, supported by modular design and MCP protocol compatibility for flexible action space expansion. Through explicit division of labor, the multi-agent collaboration mechanism enables agents to focus on specific task components, thereby significantly improving execution efficiency and quality.

Experiments

The experimental results demonstrate that the ceo-py framework significantly outperforms autogen and langchain in handling tasks of varying complexity, especially in multi-step tasks with possible failures.

  • one-step-task: Tasks that can be completed with a single tool call.
  • multi-step-task: Tasks that require multiple tool calls to complete, with no possibility of tool failure.
  • multi-step-task-with-possible-failure: Tasks that require multiple tool calls to complete, where tools may fail, requiring the agent to retry and correct errors.

The deepseek-v3 model is not supported by autogen-agentchat==0.4.9.2.

Installation

  • From PYPI

      pip install ceo-py

  • From Github

    Get access to unreleased features.

      pip install git+https://github.com/vortezwohl/CEO-Agentic-AI-Framework.git

Quick Start

To start building your own agent, follow the steps listed.

  1. set environmental variable OPENAI_API_KEY

     # .env
 OPENAI_API_KEY=sk-...

  2. import required dependencies

    • Agent lets you instantiate an agent.

    • Personality is an enumeration class used for customizing personalities of agents.

      • Personality.PRUDENT makes the agent’s behavior more cautious.

      • Personality.INQUISITIVE encourages the agent to be more proactive in trying and exploring.

    • get_openai_model gives you a BaseChatModel as thought engine.

    • @ability(brain: BaseChatModel, cache: bool = True, cache_dir: str = '') is a decorator which lets you declare a function as an Ability.

    • @agentic(agent: Agent) is a decorator which lets you declare a function as an AgenticAbility.

     from ceo import (
     Agent,
     Personality,
     get_openai_model,
     ability,
     agentic
 )

  3. declare functions as basic abilities

     @ability
 def calculator(expr: str) -> float:
     # this function only accepts a single math expression
     return simplify(expr)

 @ability
 def write_file(filename: str, content: str) -> str:
     with open(filename, 'w', encoding='utf-8') as f:
         f.write(content)
     return f'{content} written to {filename}.'

  4. instantiate an agent

    You can grant abilities to agents while instantiating them.

     model = get_openai_model()
 agent = Agent(abilities=[calculator, write_file], brain=model, name='CEO', personality=Personality.INQUISITIVE)

    • You can also grant more abilities to agents later:

        agent.grant_ability(calculator)

      or

        agent.grant_abilities([calculator])

    • To deprive abilities:

        agent.deprive_ability(calculator)

      or

        agent.deprive_abilities([calculator])

    You can change an agent’s personality using method change_personality(personality: Personality)

     agent.change_personality(Personality.PRUDENT)

  5. assign a request to your agent

     agent.assign("Here is a sphere with radius of 9.5 cm and pi here is 3.14159, find the area and volume respectively then write the results into a file called 'result.txt'.")

  6. leave the rest to your agent

     response = agent.just_do_it()
 print(response)

ceo also supports multi-agent collaboration scenario, declare a function as agent calling ability with @agentic(agent: Agent), then grant it to an agent. See example.

Integration with MCP

I provide McpAgent to support tool calls based on the MCP protocol. Below is a brief guide to integrating McpAgent with mcp.stdio_client:

  1. import required dependencies

    • McpAgent allows you to instantiate an agent capable of accessing MCP tools.

    • StdioMcpConfig is an alias for mcp.client.stdio.StdioServerParameters and serves as the MCP server connection configuration.

    • @mcp_session(mcp_config: StdioMcpConfig) allows you to declare a function as an MCP session.

    • sync_call allows you to synchronizedly call a coroutine function.

     from ceo import (
     McpAgent,
     get_openai_model,
     StdioMcpConfig,
     mcp_session,
     sync_call
 )

  2. create an MCP session

    • To connect with a stdio based MCP server, use StdioMcpConfig.

        mcp_config = StdioMcpConfig(
      command='python',
      args=['./my_stdio_mcp_server.py'],
      env=dict(),
      cwd='./mcp_servers'
  )

      A function decorated with @mcp_session will receive an MCP session instance as its first parameter. A function can be decorated with multiple @mcp_session decorators to access sessions for different MCP servers.

        @sync_call
  @mcp_session(mcp_config)
  async def run(session, request: str) -> str:
      ...

    • To connect via HTTP with a SSE based MCP server, just provide the URL.

        @sync_call
  @mcp_session('http://localhost:8000/sse')
  async def run(session, request: str) -> str:
      ...

    • To connect via websocket with a WS based MCP server, provide the URL.

        @sync_call
  @mcp_session('ws://localhost:8000/message')
  async def run(session, request: str) -> str:
      ...

  3. create an McpAgent instance within the MCP session

    After creating McpAgent, you need to call the fetch_abilities() method to retrieve tool configurations from the MCP server.

     @sync_call
 @mcp_session(mcp_config)
 async def run(session, request: str) -> str:
     mcp_agent = await McpAgent(session=session, brain=model).fetch_abilities()
     ...

  4. assign tasks to the McpAgent instance and await execution result

     @sync_call
 @mcp_session(mcp_config)
 async def run(session, request: str) -> str:
     mcp_agent = await McpAgent(session=session, brain=model).fetch_abilities()
     result = await mcp_agent.assign(request).just_do_it()
     return result.conclusion

  5. call the function

     if __name__ == '__main__':
     ret = run(request='What can you do?')
     print(ret)

I also provide the complete MCP agent test script. See example.

Observability

To make the working process of agents observable, I provide two hooks, namely BeforeActionTaken and AfterActionTaken. They allow you to observe and intervene in the decision-making and execution results of each step of the agent’s actions. You can obtain and modify the agent’s decision results for the next action through the BeforeActionTaken hook, while AfterActionTaken allows you to obtain and modify the execution results of the actions (the tampered execution results will be part of the agent’s memory).

To start using hooks, follow the steps listed.

  1. bring in hooks and messages from CEO

     from ceo.brain.hook import BeforeActionTaken, AfterActionTaken
 from ceo.message import BeforeActionTakenMessage, AfterActionTakenMessage

  2. declare functions and encapsulate them as hooks

     def before_action_taken(agent: Agent, message: BeforeActionTakenMessage):
     print(f'Agent: {agent.name}, Next move: {message}')
     return message

 def after_action_taken(agent: Agent, message: AfterActionTakenMessage):
     print(f'Agent: {agent.name}, Action taken: {message}')
     return message

 before_action_taken_hook = BeforeActionTaken(before_action_taken)
 after_action_taken_hook = AfterActionTaken(after_action_taken)

    In these two hook functions, you intercepted the message and printed the information in the message. Afterwards, you returned the message unaltered to the agent. Of course, you also have the option to modify the information in the message, thereby achieving intervention in the agent’s working process.

  3. use hooks during the agent’s working process

     agent.assign(...).just_do_it(before_action_taken_hook, after_action_taken_hook)

      In multi-agent collaboration scenario, you can assign different personalities to each distinct agent. For example, in the aforementioned script, Jack’s capability is to perform calculations. I want him to try more and explore more, so Jack’s personality is set to Personality.INQUISITIVE. On the other hand, Taylor’s capability is to create and write files. For operations involving interaction with the external file system, I want him to be more cautious, so Taylor’s personality is set to Personality.PRUDENT.

 What is reinforcement learning (RL)?
 Reinforcement learning (RL) is a type of machine learning process that focuses on decision making by autonomous agents. An autonomous agent is any system that can make decisions and act in response to its environment independent of direct instruction by a human user. Robots and self-driving cars are examples of autonomous agents.
