Build generative UI apps with OpenUI and OpenUI Lang — the token-efficient open standard for LLM-generated interfaces. Use when mentioning OpenUI, @openuidev, generative UI, streaming UI from LLMs, component libraries for AI, or replacing json-render/A2UI. Covers scaffolding, defineComponent, system prompts, the Renderer, and debugging OpenUI Lang output.

Build, edit, or read durable apps in the workspace. REQUIRED before calling `app_create`, `app_update`, `get_app`, or `create_markdown_artifact`. Full reactive surface — `$state`, `Query`, `Mutation`, `@Run`/`@Set`/`@Reset`, scheduled refresh, persistent SQLite. Use for dashboards, briefings, command centers, trackers — any persistent surface the user reopens.

Provides comprehensive guidance for building AI-powered Generative UI applications with the Thesys C1 API and GenUI SDK. Use it when developing interactive UI components, chat interfaces, dashboards, or any application that benefits from dynamically generated React interfaces from natural language prompts.
