A2UI Developer Guide

This skill provides the reference for building applications, agents, and client libraries with the A2UI (Agent-Driven User Interfaces) Protocol.

A2UI is a streaming protocol that lets agents emit interactive UI components directly into a chat stream.

Core Mandates

When using A2UI, consult the reference documentation in the references/ directory. Do not guess the structure of the JSON payload, client data models, or component formats. Always verify against the specification.
