Guides Claude to build frontend interfaces that don't look like every other AI-generated site. It runs a full workflow: detects what's already in your codebase, plans the design approach, builds it, then verifies visually. The authority hierarchy is smart: existing patterns trump everything, your explicit instructions override the skill's defaults, and defaults only kick in for greenfield work. Nice that it's upfront about being a set of defaults, not hard rules. If you're tired of that generic shadcn aesthetic showing up everywhere, this gives Claude an opinionated framework for something more distinctive while still respecting what you've already built.
