What Is Google’s Agent Development Kit? An Architectural Tour

Google’s Agent Development Kit (ADK) is a fundamental shift in how developers build AI-powered applications. Rather than treating large language models as simple request-response systems, ADK introduces an event-driven runtime architecture that orchestrates agents, tools and persistent state into cohesive applications.

This article explores the core architectural components of ADK and demonstrates how they work together, via a practical implementation of a weather agent.
