Use this skill when designing an AI feature that returns UI components (cards, forms, charts, tables, layouts) instead of text. Covers the component-vs-text decision tree, GenUX layout primitives, disclosure rules, validation gates for model-composed UI, and graceful fallback to text when the model can't compose. Triggers on "generative UI", "GenUX", "streamUI", "AI returns components", "AI SDK RSC", "Anthropic Artifacts", "ChatGPT Canvas", "design AI components", "model composes UI".
