🎯 Tutorial 1: Your First ADK Agent

Welcome to your first step in the Google ADK journey! This tutorial introduces you to the fundamental concept of creating a simple AI agent using Google's Agent Development Kit.

🎯 What You'll Learn

• Basic Agent Creation: How to create your first ADK agent
• ADK Workflow: Understanding the agent lifecycle
• Simple Text Processing: Basic input/output handling
• Agent Configuration: Essential parameters and settings

🧠 Core Concept: What is an ADK Agent?

An ADK agent is a programmable AI assistant that can:

• Process user inputs (text, images, etc.)
• Use AI models (like Gemini) to understand and respond
• Perform specific tasks based on your instructions
• Return structured or unstructured responses

Think of it as creating a smart function that uses AI to handle complex tasks.

🔧 Key Components

1. LlmAgent Class

The main building block for creating AI agents in ADK:

from google.adk.agents import LlmAgent

2. Essential Parameters

• name: Unique identifier for your agent
• model: The AI model to use (e.g., "gemini-3-flash-preview")
• description: What your agent does
• instruction: How your agent should behave

3. Basic Workflow

1. Input: User sends a message
2. Processing: Agent uses AI model to understand and respond
3. Output: Agent returns a response

🚀 Tutorial Overview

In this tutorial, we'll create a Creative Writing Agent that:

• Helps users develop story ideas and characters
• Provides writing prompts and inspiration
• Assists with plot structure and pacing
• Demonstrates basic ADK functionality

🎯 Learning Objectives

By the end of this tutorial, you'll understand:

• ✅ How to create a basic ADK agent
• ✅ Essential agent parameters and their purpose
• ✅ How to run and test your agent
• ✅ Basic ADK workflow and lifecycle

🚀 Getting Started

1. Set up your environment:

   # Make sure you have your Google AI API key
   # Get your API key from: https://aistudio.google.com/
   

2. Install dependencies:

   # Install required packages
   pip install -r requirements.txt
   

3. Run the creative writing agent:

   # Start the ADK web interface
   adk web
   
   # In the web interface, select: creative_writing_agent
   

4. Test your agent:

   • Try asking for story ideas: "I want to write a story about a magical forest"
   • Get character help: "Help me create a protagonist for my sci-fi story"
   • Request writing prompts: "Give me a creative writing prompt"
   • Ask for plot advice: "How can I structure my story's climax?"

🔗 Next Steps

After completing this tutorial, you'll be ready for:

• Tutorial 2: Model agnostic Agent - create agents that work with different AI models
• Tutorial 3: Structured Output Agent - Learn to create type-safe, structured responses
• Tutorial 4: Tool Using Agent - Add custom tools and functions to your agent

💡 Pro Tips

• Start Simple: Begin with basic functionality and add complexity gradually
• Test Often: Use the ADK web interface to test your agents
• Read Instructions: Clear instructions lead to better agent behavior
• Experiment: Try different models and parameters to see the differences
