Default AI web output has a look: Inter everywhere, flat layouts, timid spacing, motion that feels random. This skill exists to beat that default. It drives a build from strong references and one precise prompt instead of a vague description, then runs deliberate review passes until the site earns the word premium.
The steps that do the work: detect greenfield versus redesign first, because misclassifying that is the biggest source of bad output. Lock the typography and palette before any code. Choose honestly between a real design system with an official package and an aesthetic, and never confuse the two. Then iterate section by section, never regenerating the whole page.
This is the process behind the Elizabeth Ige site and the redesign of the site you are reading. The skill is a set of instructions Claude follows, which means the taste is versioned, reusable, and improvable like any other code.
