A Coding Guide to Build a Scalable Multi-Agent System with Google ADK

This tutorial delves into the advanced capabilities of Google’s Agent Development Kit (ADK) by guiding you through the process of building a multi-agent system. The system will be equipped with specialized roles and tools, allowing agents to perform tasks such as web research, mathematical computation, data analysis, and content creation. By integrating Google Search, asynchronous execution, and modular architecture, we will demonstrate how to orchestrate a powerful, production-ready agent workflow using the Gemini model.

Installing the Google ADK Package

To get started, we need to install the Google ADK package:

!pip install google-adk

Next, we will import the necessary libraries and authenticate our access by retrieving the Google API key. This ensures our agents can interact seamlessly with Google’s tools and services.

Setting Up the API Key

def get_api_key():
    api_key = os.getenv("GOOGLE_API_KEY")
    if not api_key:
        from getpass import getpass
        api_key = getpass("Enter your Google API Key: ")
        if not api_key:
            raise ValueError("API key is required to run this tutorial")
        os.environ["GOOGLE_API_KEY"] = api_key
    return api_key

Creating Specialized Agents

We will define a TaskResult data structure to store outputs from each agent. Then, we will build a multi-agent system using Google ADK, assigning specialized roles such as researcher, calculator, analyst, and writer. Through asynchronous methods, we will demonstrate each agent’s capabilities and compile a final summary of their performance and insights.

class AdvancedADKTutorial:
    def __init__(self):
        self.model = "gemini-1.5-flash"
        self.agents = {}
        self.results = []
        
    def create_specialized_agents(self):
        self.agents['researcher'] = Agent(
            name="researcher",
            model=self.model,
            instruction="You are a research specialist. Use Google Search to find accurate, up-to-date information.",
            description="Specialist in web research and information gathering",
            tools=[google_search]
        )
        self.agents['calculator'] = Agent(
            name="calculator",
            model=self.model,
            instruction="You are a mathematics expert. Solve calculations step-by-step.",
            description="Expert in mathematical calculations and problem solving"
        )
        self.agents['analyst'] = Agent(
            name="analyst",
            model=self.model,
            instruction="You are a data analysis expert. Calculate basic statistics.",
            description="Specialist in data analysis and statistical insights"
        )
        self.agents['writer'] = Agent(
            name="writer",
            model=self.model,
            instruction="You are a professional writing assistant. Help with content creation.",
            description="Expert in content creation and document writing"
        )

Demonstrating Agent Capabilities

We will utilize asynchronous functions to showcase the capabilities of each specialized agent, including:

  • Research tasks using Google Search.
  • Mathematical calculations, including financial metrics.
  • Data analysis for business insights.
  • Content generation for reports and documentation.

Each demonstration will highlight the agent’s ability to process inputs and provide actionable outputs, showcasing the flexibility of the multi-agent system.

Summary of Agent Performances

def display_comprehensive_summary(self):
    print(f"Total agents created: {len(self.agents)}")
    print(f"Total tasks completed: {len(self.results)}")
    print(f"Model used: {self.model}")
    print("Agent capabilities demonstrated include advanced web research, mathematical computations, data analysis, and content creation.")

Through this hands-on experience, we will gain confidence in using ADK to develop robust agent-based solutions for real-world problems. The ADK framework supports error handling, extensibility, and seamless integration with various tools.

Conclusion

In summary, this guide provides a comprehensive overview of building a scalable multi-agent system using Google ADK. By understanding the target audience’s needs and challenges, we can tailor our approach to ensure effective learning and application. The insights gained from this tutorial will empower professionals to harness the potential of AI in their workflows, leading to enhanced productivity and innovation.
