Two design skills · both proven

minimalist-ui 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.

minimalist-ui

Classic style skill, opt-in: it runs only when called by name. Editorial product UI with a warm monochrome palette, typographic contrast and flat bento grids.

theme-factory

Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.

We don’t pick a winner for you: the pages are the evidence. Both proofs can be repeated with the brief, model and commit shown above. See alternatives to minimalist-ui or alternatives to theme-factory.
