A2UI: LLM-generated UI protocol (Google)

A new open source UI Toolkit to facilitate LLM-generated UIs. A2UI is built with A2A protocol and allows an A2A agent to send interactive components instead of just text, using a high level framework-agnostic format that can be rendered natively on any surface (starting with examples for web and mobile).

- Based on A2A - Streamable JSON Lines (JSONL) - Truly Framework-Agnostic
