MASLibPy: Multi-Agent System Library

maslibpy is a lightweight, modular Python library designed to facilitate the creation and management of multi-agent systems. It provides a structured framework for building agents, defining their communication protocols, and integrating them with various Large Language Models (LLMs).

Features

• Modular design for agent creation and management.
• Built-in support for system, user, and assistant message flows.
• Seamless integration with multiple LLM providers (e.g., OpenAI, Together, Groq, Replicate).
• Easy-to-use APIs for invoking and orchestrating agent interactions.
• Dynamic crew management for multi-agent collaborations.

File Descriptions

Agent:

• baseagent.py: Contains the base agent class BaseAgent with core properties like id, name, role, and goal. Also includes integration with LLMs.
• agent.py: Implements the Agent class, extending BaseAgent. It defines the agent's behavior, including how queries are handled and responses are generated.
• agent_prompt.py: Provides the template prompt used by agents for structured reasoning and interaction.

Message:

• base.py: Defines the foundational BaseMessage class for managing the message flow within the system.
• system.py: Implements the SystemMessage class for system-level communication.
• user.py: Implements the UserMessage class for user-initiated communication.
• assistant.py: Implements the AIMessage class for assistant responses.

Pattern:

• sequential.py: Implements the Crew class, which manages a group of agents and orchestrates their collaborative tasks using an LLM backend in a sequantial manner.

LLM:

• llm.py: Manages LLM integration, including provider validation, model invocation, and environment variable checks for API keys.
• constants.py: Defines environment variables, supported LLM providers, and available model configurations.

Example Usage

Note: pattern/sequential.py was previsously crew/crew.py

from maslibpy.agent.agent import Agent
from maslibpy.crew.crew import Crew
from maslibpy.llm.llm import LLM

    name="Symptom Collector Agent",
    role="Gather user-provided symptoms and health details.",
    goal="Ensure accurate and complete collection of symptoms to aid in diagnosis",
    backstory=" A meticulous assistant trained in identifying and documenting symptoms for medical evaluations.",
    llm=LLM(provider="groq",model_name="groq/llama-3.1-8b-instant")
)

diagnosis_agent=Agent(
    name="Diagnosis Agent",
    role="Analyze symptoms to hypothesize potential diagnoses.",
    goal=" Provide an accurate and reasoned diagnosis based on the input symptoms",
    backstory="A seasoned diagnostician trained on vast medical data to recognize patterns in health issues.",
    llm=LLM(provider="groq",model_name="groq/llama-3.1-8b-instant")
)

treatment_recommender_agent=Agent(
    name="Treatment Recommender Agent",
    role="Suggest treatments or next steps based on diagnosis.",
    goal=" Recommend the most effective and feasible treatment options.",
    backstory="A caring guide with expertise in medical treatments, always prioritizing patient well-being.",
    llm=LLM(provider="groq",model_name="groq/llama-3.1-8b-instant")
)

sys_prompt="""
You are an assistant helping in healthcare diagnosis.  
- Step 1: Symptom Collector: Collect and summarize symptoms and relevant information from the user.  
- Step 2: Diagnosis Agent: Based on the collected symptoms, suggest a potential diagnosis with reasoning.  
- Step 3: Treatment Recommender: Provide treatment options or next steps.  
Always think step-by-step and clearly explain your reasoning at each stage.

# Main #

crew=Crew([symptom_collector_agent,diagnosis_agent,treatment_recommender_agent],
          system_prompt=sys_prompt)
