Anthropic’s frontend-design skill helps an agent make deliberate visual decisions before building an interface. It is useful when a landing page or application looks generic even though its components work. The starting point is the actual subject, its audience and the page’s main job.
The instructions ask the agent to connect typography, color, layout and content to that brief. A display face should contribute to the page’s identity; section labels and numbering should communicate something real about the information. Familiar layouts remain available when they suit the project, but the skill asks for a reason to choose them.
The workflow includes planning, implementation and critique. It also treats interface writing as part of the design: labels should describe actions people understand, rather than expose internal machinery. Motion, when useful, should serve the page and respect reduced-motion preferences. Responsive layout and visible keyboard focus remain part of the final check.
This is an instruction package, not a ready-made component library. It needs an agent with the tools required to build and inspect the target interface. A useful input includes the product context, real content and any existing visual constraints. The skill is Apache-2.0 licensed; its guidance does not substitute for inspecting the rendered result.
