Two design skills · both proven

ui-ux-pro-max vs web-artifacts-builder

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work.

ui-ux-pro-max

UI/UX design intelligence for web, mobile, and desktop.

Brief: “Build the dashboard home screen for Tally, a personal finance app: a sidebar, a header with the account switcher, a balance hero, a monthly spending chart drawn with inline SVG, a recent transactions list, budget progress cards, and an upcoming bills panel. It should feel like a finished product, with hover states and subtle motion.”

web-artifacts-builder

Brief: “Build a single-page trip planner for a four-day weekend in Lisbon as one self-contained HTML file: a day-by-day itinerary with editable stops, a running budget that totals by category, a packing checklist with progress, and a simple map panel drawn with inline SVG that highlights the selected day's stops. State should live in the page and update everywhere when anything changes.”
