Two design skills · both proven

slides 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.

slides

Create strategic HTML presentations with Chart.js, design tokens, responsive layouts, copywriting formulas, and contextual slide strategies.

Brief: “Make an 8-slide HTML presentation for a seed pitch: Tallyroom, software that lets independent gyms take class bookings and payments in one place. Revenue $18,000 a month, growing 14% month over month, 140 gyms, raising $1.5M. Include the problem, product, traction with a chart, business model, market, team of three, and the ask.”

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.”
