What it does
One DESIGN.md file that tells an AI screen generator exactly how your product should look, so the screens stop coming out generic. It is written for Google Stitch, but the file reads fine as a plain style brief. You describe the feel you want. The skill sets three dials first: how dense the layout is, how much it breaks symmetry, and how much it moves. Then it names each colour with a hex code and a job, caps you at one accent, and bans the purple neon look. It picks fonts, spacing, and button and card behaviour, and ends with a list of banned clichés. Review the result against your real brand before you use it.
You give it
- A few lines on your product and its mood
- Who the product is for
