Why AgentScope Exists: The Drawback It Solves

As LLM functions develop extra advanced, builders more and more depend on a number of brokers working collectively. Nevertheless, many groups battle with managing agent interactions, shared state, and long-term reminiscence reliably. 

AgentScope solves these issues by introducing specific agent abstractions, message-passing mechanisms, and structured reminiscence administration. Its core targets embody: 

• Transparency and Flexibility: The entire functioning of an agent’s pipeline, which incorporates prompts, reminiscence contents, API calls, and power utilization, is seen to the developer. You’re allowed to cease an agent in the course of its reasoning course of, test or change its immediate, and proceed execution with none difficulties. 
• Multi-Agent Collaboration: With regards to performing sophisticated duties, the necessity for a number of specialised brokers is most well-liked over only one massive agent. AgentScope has built-in assist for coordinating many brokers collectively. 
• Integration and Extensibility: AgentScope was designed with extensibility and interoperability in thoughts. It makes use of the newest requirements just like the MCP and A2A for communication, which not solely permit it to attach with exterior companies but additionally to function inside different agent frameworks. 
• Manufacturing Readiness: The traits of many early agent frameworks didn’t embody the aptitude for manufacturing deployment. AgentScope aspires to be “production-ready” proper from the beginning. 

In conclusion, AgentScope is designed to make the event of advanced, agent-based AI methods simpler. It offers modular constructing blocks and orchestration instruments, thus occupying the center floor between easy LLM utilities and scalable multi-agent platforms. 

Core Ideas and Structure of AgentScope

• Agent Abstraction and Message Passing: AgentScope symbolizes each agent as a standalone entity with a particular perform, psychological state, and choice-making course of. Brokers don’t trade implicit secret context, thus minimizing the prevalence of unpredictable actions. 
• Fashions, Reminiscence, and Instruments: AgentScope divides intelligence, reminiscence, and execution into separate parts. This partitioning permits the builders to make adjustments to every half with out disrupting all the system. 
• Mannequin Abstraction and LLM Suppliers: AgentScope abstracts LLMs behind a consolidated interface, henceforth permitting easy transitions between suppliers. Builders can select between OpenAI, Anthropic, open-source fashions, or native inference engines. 
• Quick-Time period and Lengthy-Time period Reminiscence: AgentScope differentiates between short-term conversational reminiscence and long-term persistent reminiscence. Quick-term reminiscence offers the context for fast reasoning, whereas long-term reminiscence retains information that lasts. 
• Instrument and Perform Invocation: AgentScope provides brokers the chance to name exterior instruments through structured perform execution. These instruments may encompass APIs, databases, code execution environments, or enterprise methods. 

Key Capabilities of AgentScope

AgentScope is an all-in-one bundle of a number of highly effective options which permits multi-agent workflows. Listed here are some principal strengths of the framework already talked about:  

• Multi-Agent Orchestration: AgentScope is a grasp within the orchestration of quite a few brokers working to realize both overlapping or opposing targets. Furthermore, the builders have the choice to create a hierarchical, peer-to-peer, or perhaps a coordinator-worker method.  

async with MsgHub(
    individuals=[agent1, agent2, agent3],
    announcement=Msg("Host", "Introduce yourselves.", "assistant"),
) as hub:
    await sequential_pipeline([agent1, agent2, agent3])

    # Add or take away brokers on the fly
    hub.add(agent4)
    hub.delete(agent3)

    await hub.broadcast(Msg("Host", "Wrap up."), to=[])

• Instrument Calling and Exterior Integrations: AgentScope has a easy and easy integration with the exterior methods through software calling mechanisms. This function helps to show brokers from easy conversational entities into environment friendly automation parts that perform actions.  
• Reminiscence Administration and Context Persistence: With AgentScope, the builders have the facility of explicitly controlling the context of the brokers’ storage and retrieval. Thus, they resolve what info will get retained and what will get to be transient. The advantages of this transparency embody the prevention of context bloating, fewer hallucinations, and reliability in the long run. 

QuickStart with AgentScope

Should you observe the official quickstart, the method of getting AgentScope up and working is kind of simple. The framework necessitates Python model 3.10 or above. Set up will be carried out both via PyPI or from the supply:

From PyPI:

Run the next instructions within the command-line:

pip set up agentscope 

to put in the newest model of AgentScope and its dependencies. (If you’re utilizing the uv setting, execute uv pip set up agentscope as described within the docs) 

From Supply:  

Step 1: Clone the GitHub repository: 

git clone -b important https://github.com/agentscope-ai/agentscope.git 
cd agentscope 

Step 2: Set up in editable mode: 

pip set up -e . 

It will set up AgentScope in your Python setting, linking to your native copy. You may also use uv pip set up -e . if utilizing an uv setting.  

After the set up, you need to have entry to the AgentScope courses inside Python code. The Hiya AgentScope instance of the repository presents a really fundamental dialog loop with a ReActAgent and a UserAgent.  

AgentScope doesn’t require any further server configurations; it merely is a Python library. Following the set up, it is possible for you to to create brokers, design pipelines, and do some testing instantly. 

Making a Multi-Agent Workflow with AgentScope

Let’s create a practical multi-agent system wherein two AI fashions, Claude and ChatGPT, possess totally different roles and compete with one another: Claude generates issues whereas GPT makes an attempt to unravel them. We will clarify every a part of the code and see how AgentScope really manages to carry out this interplay. 

1. Setting Up the Atmosphere 

Importing Required Libraries 

import os
import asyncio
from typing import Checklist

from pydantic import BaseModel
from agentscope.agent import ReActAgent
from agentscope.formatter import OpenAIChatFormatter, AnthropicChatFormatter
from agentscope.message import Msg
from agentscope.mannequin import OpenAIChatModel, AnthropicChatModel
from agentscope.pipeline import MsgHub

All the mandatory modules from AgentScope and Python’s commonplace library are imported. The ReActAgent class is used to create the clever brokers whereas the formatters make sure that messages are ready accordingly for the varied AI fashions. Msg is the communication technique between brokers supplied by AgentScope. 

Configuring API Keys and Mannequin Names 

os.environ["OPENAI_API_KEY"] = "your_openai_api_key"
os.environ["ANTHROPIC_API_KEY"] = "your_claude_api_key"

OPENAI_API_KEY = os.environ["OPENAI_API_KEY"]
ANTHROPIC_API_KEY = os.environ["ANTHROPIC_API_KEY"]

CLAUDE_MODEL_NAME = "claude-sonnet-4-20250514"
GPT_SOLVER_MODEL_NAME = "gpt-4.1-mini"

This setup will assist in authenticating the API credentials for each OpenAI and Anthropic. And to entry a selected mannequin we now have to go the particular mannequin’s title additionally.  

2. Defining Knowledge Constructions for Monitoring Outcomes 

Spherical Log Construction: 

class RoundLog(BaseModel):
    round_index: int
    creator_model: str
    solver_model: str
    downside: str
    solver_answer: str
    judge_decision: str
    solver_score: int
    creator_score: int

This information mannequin holds all the knowledge concerning each spherical of the competition in real-time. Collaborating fashions, generated issues, solver’s suggestions, and present scores are being recorded thus making it straightforward to assessment and analyze every interplay. 

International Rating Construction: 

class GlobalScore(BaseModel):
    total_rounds: int
    creator_model: str
    solver_model: str
    creator_score: int
    solver_score: int
    rounds: Checklist[RoundLog]

The general competitors outcomes throughout all rounds are saved on this construction. It preserves the ultimate scores and all the rounds historical past thus providing us a complete view of brokers’ efficiency within the full workflow. 

Normalizing Agent Messages 

def extract_text(msg) -> str:
    """Normalize an AgentScope message (or related) right into a plain string."""
    if isinstance(msg, str):
        return msg

    get_tc = getattr(msg, "get_text_content", None)
    if callable(get_tc):
        textual content = get_tc()
        if isinstance(textual content, str):
            return textual content

    content material = getattr(msg, "content material", None)
    if isinstance(content material, str):
        return content material

    if isinstance(content material, checklist):
        elements = []
        for block in content material:
            if isinstance(block, dict) and "textual content" in block:
                elements.append(block["text"])
        if elements:
            return "n".be a part of(elements)

    text_attr = getattr(msg, "textual content", None)
    if isinstance(text_attr, str):
        return text_attr

    messages_attr = getattr(msg, "messages", None)
    if isinstance(messages_attr, checklist) and messages_attr:
        final = messages_attr[-1]
        last_content = getattr(final, "content material", None)
        if isinstance(last_content, str):
            return last_content

        last_text = getattr(final, "textual content", None)
        if isinstance(last_text, str):
            return last_text

    return ""

Our perform here’s a supporting one that permits us to acquire readable textual content from agent responses with reliability whatever the message format. Totally different AI fashions have totally different buildings for his or her responses so this perform takes care of all of the totally different codecs and turns them into easy strings we are able to work with. 

4. Constructing the Agent Creators 

Creating the Drawback Creator Agent (Claude) 

def create_creator_agent() -> ReActAgent:
    return ReActAgent(
        title="ClaudeCreator",
        sys_prompt=(
            "You're Claude Sonnet, performing as an issue creator. "
            "Your process: in every spherical, create ONE life like on a regular basis downside that "
            "some individuals may face (e.g., scheduling, budgeting, productiveness, "
            "communication, private choice making). "
            "The issue ought to:n"
            "- Be clearly described in 3–6 sentences.n"
            "- Be self-contained and solvable with reasoning and customary sense.n"
            "- NOT require non-public information or exterior instruments.n"
            "Return ONLY the issue description, no resolution."
        ),
        mannequin=AnthropicChatModel(
            model_name=CLAUDE_MODEL_NAME,
            api_key=ANTHROPIC_API_KEY,
            stream=False,
        ),
        formatter=AnthropicChatFormatter(),
    )

This utility produces an assistant that takes on the position of Claude and invents life like issues of on a regular basis life that aren’t essentially such. The system immediate specifies the form of issues to be created, primarily making it the situations the place reasoning is required however no exterior instruments or non-public info are required for fixing them. 

Creating the Drawback Solver Agent (GPT) 

def create_solver_agent() -> ReActAgent:
    return ReActAgent(
        title="GPTSolver",
        sys_prompt=(
            "You're GPT-4.1 mini, performing as an issue solver. "
            "You'll obtain a sensible on a regular basis downside. "
            "Your process:n"
            "- Perceive the issue.n"
            "- Suggest a transparent, actionable resolution.n"
            "- Clarify your reasoning in 3–8 sentences.n"
            "If the issue is unclear or unimaginable to unravel with the given "
            "info, you MUST explicitly say: "
            ""I can not remedy this downside with the knowledge supplied.""
        ),
        mannequin=OpenAIChatModel(
            model_name=GPT_SOLVER_MODEL_NAME,
            api_key=OPENAI_API_KEY,
            stream=False,
        ),
        formatter=OpenAIChatFormatter(),
    )

This software additionally provides start to a different agent powered by GPT-4.1 mini whose important process is to discover a resolution to the issue. The system immediate dictates that it should give a transparent resolution together with the reasoning, and most significantly, to acknowledge when an issue can’t be solved; this frank recognition is important for correct scoring within the competitors. 

5. Implementing the Judging Logic 

Figuring out Resolution Success 

def solver_succeeded(solver_answer: str) -> bool:
    """Heuristic: did the solver handle to unravel the issue?"""
    textual content = solver_answer.decrease()

    failure_markers = [
        "i cannot solve this problem",
        "i can't solve this problem",
        "cannot solve with the information provided",
        "not enough information",
        "insufficient information",
    ]

    return not any(marker in textual content for marker in failure_markers)

This judging perform is straightforward but highly effective. If the solver has really supplied an answer or confessed failure the perform will test. By trying to find sure expressions that present the solver was not capable of handle the problem, the winner of each spherical will be determined robotically with out the necessity for human intervention. 

6. Operating the Multi-Spherical Competitors 

Foremost Competitors Loop

    solver_agent = create_solver_agent()
    creator_score = 0
    solver_score = 0
    round_logs: Checklist[RoundLog] = []

    for i in vary(1, num_rounds + 1):
        print(f"n========== ROUND {i} ==========n")

        # Step 1: Claude creates an issue
        creator_msg = await creator_agent(
            Msg(
                position="consumer",
                content material="Create one life like on a regular basis downside now.",
                title="consumer",
            ),
        )

        problem_text = extract_text(creator_msg)
        print("Drawback created by Claude:n")

                content material=(
                    "Right here is the issue you need to remedy:nn"
                    f"{problem_text}nn"
                    "Present your resolution and reasoning."
                ),
                title="consumer",
            ),
        )

        solver_text = extract_text(solver_msg)
        print("GPT-4.1 mini's resolution:n")
        print(solver_text)
        print("n---n")

        # Step 3: Choose the consequence
        if solver_succeeded(solver_text):
            solver_score += 1
            judge_decision = "Solver (GPT-4.1 mini) efficiently solved the issue."
        else:
            creator_score += 1
            judge_decision = (
                "Creator (Claude Sonnet) will get the purpose; solver failed or admitted failure."
            )

        print("Choose choice:", judge_decision)
        print(f"Present rating -> Claude: {creator_score}, GPT-4.1 mini: {solver_score}")

        round_logs.append(
            RoundLog(
                round_index=i,
                creator_model=CLAUDE_MODEL_NAME,
                solver_model=GPT_SOLVER_MODEL_NAME,
                downside=problem_text,
                solver_answer=solver_text,
                judge_decision=judge_decision,
                solver_score=solver_score,
                creator_score=creator_score,
            )
        )

    global_score = GlobalScore(
        total_rounds=num_rounds,
        creator_model=CLAUDE_MODEL_NAME,
        solver_model=GPT_SOLVER_MODEL_NAME,
        creator_score=creator_score,
        solver_score=solver_score,
        rounds=round_logs,
    )

    # Ultimate abstract print
    print("n========== FINAL RESULT ==========n")
    print(f"Whole rounds: {num_rounds}")
    print(f"Creator (Claude Sonnet) rating: {creator_score}")
    print(f"Solver (GPT-4.1 mini) rating: {solver_score}")

    if solver_score > creator_score:
        print("nOverall winner: GPT-4.1 mini (solver)")
    elif creator_score > solver_score:
        print("nOverall winner: Claude Sonnet (creator)")
    else:
        print("nOverall consequence: Draw")

    return global_score

This represents the core of our multi-agent course of. Each spherical Claude proposes a difficulty, GPT tries to unravel it, and we resolve the scores are up to date and the whole lot is logged. The async/await sample makes the execution easy, and after all of the rounds are over, we current the entire outcomes that point out which AI mannequin was total higher.
