Reseed CLI: Extract Design Systems from Any Site for Claude Code and Cursor

Reseed is a CLI tool that extracts a real design system from any live website — your own, a reference, or a competitor — and drops it directly into your repo. The output includes a tailwind.config.ts with actual colors, spacing, type scale, and radii; a design-system.md that agents can read every session; and a self-contained reference HTML so the model has visual ground truth.

How It Works

The pipeline runs entirely with Claude Code and plain TypeScript. Opus 4.7 performs the vision analysis on source screenshots. The rest is TypeScript to keep costs bounded and output reproducible across runs. Run it once, commit, and every future Claude Code or Cursor session in that repo respects the design system.

Key Workflow Insight

The creator found that Claude kept defaulting to generic "AI tells" — purple gradients, glassmorphism, drop-shadow stacks, oversized rounded cards. The fix wasn't more prompting; it was giving the agent an explicit list of patterns the source design avoids. That single change made the generated UI stop looking AI-generated.

Availability

The tool is free to try with 3 extractions on the free tier, no credit card needed. Available at https://reseedapp.com.
