Two design skills · both proven

canvas-design vs vercel-react-view-transitions

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.

Brief: “Build a photo gallery for a small travel photographer as a single HTML page using React from a CDN: a grid of twelve photos drawn with inline SVG or CSS gradients, where clicking a photo smoothly expands it into a detail view with a caption and location, and going back animates it into its place in the grid.
