This is the frontend design skill that actually has opinions. Use it when you need to build, critique, or polish UI, whether that's a landing page, dashboard, or component library. It enforces real standards: contrast ratios you can measure, typography ceilings that prevent 11rem headlines, motion with reduced-motion fallbacks baked in. The setup is methodical: it reads your project context, checks for existing design systems, generates brand palettes for greenfield work, and loads different guidance depending on whether you're building marketing surfaces or product UI. No prototypes, no shortcuts unless you ask. It screenshots and tests as it goes. If you've ever inherited AI-generated frontend that looked designed but felt unfinished, this is the correction.
