reseed-cli

Drop a design system from any URL into your codebase, where your AI editor can use it.

reseed extracts the design language of any website — colors, typography, spacing, component patterns, the rules that make it feel that way — and drops a design-system.md rules file into your project. Cursor, Claude Code, and Windsurf read the rules and start producing UI that looks like the site you picked.

npx reseed-cli login
npx reseed-cli init https://linear.app

That's it. From the next prompt on, your AI editor follows Linear's design language.

The package is reseed-cli on npm; the binary on your PATH is reseed. So you can also npm i -g reseed-cli once and then run reseed init ….

What lands in your repo

.reseed/
├── design-system.md         ← rules file, loaded via CLAUDE.md / AGENTS.md
├── theme.css                ← Tailwind v4 @theme tokens (or tailwind.config.ts for v3)
├── design-reference.html    ← self-contained visual reference
└── source.json              ← frozen extraction record

reseed init also appends a one-line pointer to your existing CLAUDE.md or AGENTS.md so your AI editor automatically discovers the rules.

How it works

1. Reseed scrapes the page on its servers (Playwright + Claude vision).
2. Returns a structured rules file written from a senior designer's perspective: identity paragraph, hard rules, token tables, component patterns, anti-patterns.
3. Writes the four files into your repo.

Cost is shared via your account's quota: 3 free extractions, then $19/month for 15 extractions on PRO. Sign up at reseedapp.com.

Editor integrations

Reseed appends a single pointer to whichever rules file your editor reads:

• Cursor → .cursor/rules
• Claude Code → CLAUDE.md
• Windsurf / Cline → AGENTS.md
• GitHub Copilot → .github/copilot-instructions.md

If none exist, Reseed creates CLAUDE.md with the pointer.
