Two design skills · both proven

design-system vs theme-factory

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.

design-system

Token architecture, component specifications, and slide generation. Three-layer tokens (primitive→semantic→component), CSS variables, spacing/typography scales, component specs, strategic slide creation. Use for design tokens, systematic design, brand-compliant presentations.

Brief: “Create the design system for Ledgerline, bookkeeping software for freelance designers, as a single HTML page: color tokens with light and dark values, a type scale, spacing and radius tokens, and live examples of buttons, inputs, a table row, a toast and a card built only from those tokens.”

theme-factory

Brief: “Build the one-page invitation site for the Harvest Table, a community garden's autumn dinner: a hero with the date and place, the story of the garden, the menu by course, the people cooking, a map drawn in inline SVG, and an RSVP form with success and error states. Make it feel warm and finished.”
