Two design skills · both proven

brainstorming 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.

brainstorming

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 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.”
