-The A2UI (Agent-to-UI) protocol type system and parsing/resolution utilities for TypeScript, targeting the **A2UI v0.9.1 stable release**. Defines the wire format agents use to drive generative UI surfaces — framework-agnostic, no Angular dependency, runs in any TypeScript environment.
+The A2UI (Agent-to-UI) protocol layer behind generative UI in [Threadplane](https://github.com/cacheplane/angular-agent-framework), the AI agent UI framework for Angular, targeting the **A2UI v0.9.1 stable release**. It defines the wire format an agent uses to drive a UI surface, plus the parser and resolver that read it — framework-agnostic, pure TypeScript, no Angular dependency, usable in any TypeScript environment.

+The chat surface of [Threadplane](https://github.com/cacheplane/angular-agent-framework), the AI agent UI framework for Angular. Headless primitives plus opinionated compositions read a runtime-neutral `Agent` contract, so the UI is built once and runs over LangGraph or AG-UI without changes. Angular 20–22, on Signals and DI.
