freedesignmd is a free library of curated design.md files for AI agents like Claude, Cursor, and Lovable. Each DESIGN.md is a single markdown file that defines your color tokens, typography, spacing, components, and layout rules — exactly the context an AI coding tool needs to ship consistent UI on the first try.
Most AI-generated apps look the same: generic gradients, mismatched buttons, drifting spacing. A good design.md file fixes that. It gives your agent a small, strict contract: which fonts to load, which radii to use, how cards stack, what a primary CTA looks like. Same prompt, ten times — same UI.
Every file in the directory is free to download, free to remix, and free to ship in commercial work. No login. No paywall. Just copy the markdown, drop it into your project root as DESIGN.md, and tell your agent to follow it.
