Turns requirements and PRDs into wireframes, user flows, and accessibility specs. You'd use this in the planning phase before architecture and development to map out screens, navigation paths, and interaction patterns. It's got WCAG 2.1 AA compliance built in with contrast checkers and accessibility checklists, plus templates for design docs and user flows. The ASCII wireframes are practical for text-based collaboration, and the mobile-first approach with breakpoint scripts keeps responsive design consistent. Hands off component specs and design tokens to developers so they're not guessing at spacing or interaction states. It runs parallel subagents to design multiple screens simultaneously, which makes sense for larger apps with 5-10 distinct flows.
