This repository is the web-based user interface for the Google Agent Development Kit (ADK). It functions as a comprehensive IDE and debugging console for building, running, and evaluating AI agents. The application is built on Angular (v21.0.0) using Standalone Components and Signals, serving as a client to a backend agent runtime. Key capabilities include a visual workflow builder for agent graphs, real-time chat interfaces supporting text/audio/video streaming, OpenTelemetry trace ingestion and visualization, and a structured evaluation framework for agent performance metrics. It acts as the control plane for agent execution, handling configuration via YAML and managing session state through WebSocket and HTTP communication.
