Summary
Introduces AG-UI, an open protocol and UI layer for standardizing agent-to-user communication with rich UIs. Details how AG-UI, in conjunction with CopilotKit, provides a standardized communication channel between backend agents (like those built with ADK) and frontend applications. Highlights the benefits of this integration, including generative UI, shared state, human-in-the-loop capabilities, and frontend tool interaction. Provides a quick start guide with a command to clone a starter repository and code examples for defining an ADK agent and connecting it to a React/Next.js frontend using CopilotKit.
