AI agents are no longer just research concepts — they’re being deployed in production systems across industries. Google’s Agent Development Kit (ADK) makes it easier than ever to build, orchestrate, and deploy intelligent agents using Python. In this guide, I’ll walk you through building your first AI agent from scratch using Google ADK.

What is Google ADK?

Google ADK (Agent Development Kit) is an open-source framework designed to help developers build multi-agent AI systems. It provides:

• A structured way to define agents and their tools

• Built-in orchestration for sequential and parallel workflows

• Native integration with Gemini AI models

• YAML-based configuration for agent behavior

Think of it as the backbone that connects your AI model to real-world actions.
