Have you ever wondered how we use our own tools to build themselves? In this session, you'll go behind the scenes of the Gemini CLI, where we’ll show you how we’re evolving it from a command line into an enterprise-grade developer agent. You will explore our modular capabilities for complex workflows, specifically focusing on skills and extensions. We’ll provide a deep dive into agent-to-agent (A2A) communication, demonstrating how we use it to supercharge the CLI with local and remote agents. And we'll detail how we address the challenge of scale, ensuring speed and security for Google-scale development.
