This skill is retired. Redesigns, restyles and reviews of existing pages and app screens are part of design-taste-frontend, which audits the existing page in a real browser first, keeps its content and working behaviour, and then rebuilds the design to a dealt direction with before-and-after screenshots.
If you were called by name, follow the design-taste-frontend skill (its "Redesign or review" route). If it is not installed:
