How external rule documents steer the design direction of AI-generated interfaces

AI 会把界面做好看了，但它把怎么好看写成了一份文档

The design direction of an AI-generated interface depends on external rules. The article groups the base model, rule documents, component libraries and compilers into what it calls the interface generation core. It uses Anthropic's frontend-design skill document as an example: the flow outputs color, typography, layout and design principles first, then writes frontend components. It contrasts this with OpenAI Intelligent UI, which relies on standardized components and streaming rendering.

Why it matters: Anthropic writes the interface design process into a skill document, fixing color, typography and layout before generating components, a method others can reuse to constrain model output to a brand direction.
