Two design skills · both proven

brainstorming 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.

You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or planning anything new, in software or out of it (a talk, a business, a renovation).

Brief: “A small bakery with one location wants more weekday morning customers. They have a loyal weekend crowd, an Instagram account with 2,000 followers, and no budget for paid ads. Work through this with me and produce the result as a single HTML page: the questions you would ask, the ideas you considered, the three you recommend with how to test each one in two weeks, and what you would measure.”

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. Filtering the grid by country should animate the reordering too.”
