A DESIGN.md for Claude Code, from any website

Tell Claude Code "make it look like that site" and you get a default blue button and Arial. Give it a DESIGN.md and it has something real to follow. Borrowstyle reads the website in your tab and writes that file for you in about half a second.

What is a DESIGN.md?

A plain Markdown file that describes a design system in words and values: which colour is primary, which is the background, how big an H1 is, how much space sits between sections, how round the corners are. AI coding tools read Markdown well, so a DESIGN.md in your repo becomes the brief Claude Code works from on every prompt.

DESIGN.md written by Borrowstyle, ready for an AI coding tool

What Borrowstyle puts in it

  • Colours with their roles (primary, surface, text, border, accent).
  • Every type style with size, weight and line height.
  • The spacing scale, corner radius and shadows.
  • The main parts of the page, like buttons, cards and inputs, with their measurements.
  • When a font is paid, its name plus a free stand-in.

Same prompt, with and without the file

Without a DESIGN.md, the AI guesses. With one, it uses the real values: the right purple, the right light headline weight, the right corner. The difference is the file, not the prompt.

Borrow the system, not the brand

Use the file to get the feel right: rhythm, type, tone of colour. Don't ship another company's logo, images, text or paid fonts. Make it yours (Pro) swaps your colours and fonts in before you hand it to Claude.
