Build ADK Agent with Skills

As AI agents become more capable, managing context, expertise, and scalability becomes increasingly challenging. In this session, we'll explore how Google Agent Development Kit (ADK) Skills help developers build modular, efficient, and production-ready agents by loading capabilities only when needed. You'll learn how Skills reduce context overhead, improve agent performance, and enable reusable expertise across multiple agents. Through examples and live demonstrations, we'll cover Skill design patterns and integration with external tools to build an AI agent.
