# StyleSeed — Design Judgment Engine > Teaches Claude Code design judgment, not just design data. 69 visual rules that make AI output look designed, not generated. ## What It Teaches - **Color discipline** — `#2A2A2A` as refined black, 5-level grayscale, one accent color maximum - **Spatial rhythm** — alternating section heights, 2:1 number-to-unit ratios - **Information hierarchy** — card/background separation, progressive density - **Shadow & elevation** — 4% opacity ceiling, dark mode border substitution - **Component variance** — never 4 identical KPI cards, stagger content types - **Motion & feedback** — 200ms normal, spring for entrance, ease-out for exit ## Quick Start ```bash # Copy engine into your project cp -r styleseed/engine/* your-project/ # Or just point Claude at the repo # "Refer to https://github.com/bitjaru/styleseed — read engine/CLAUDE.md and DESIGN-LANGUAGE.md" ``` ## Includes - 69 visual design rules (brand-agnostic) - 48 React components (shadcn-style, Tailwind CSS v4 + Radix UI) - 11 slash commands (`/ss-page`, `/ss-review`, `/ss-audit`, `/ss-lint`, etc.) - Swappable brand skins (Toss, Stripe, Linear, Vercel, Notion, Raycast, Arc) ## Links - **Repository:** https://github.com/bitjaru/styleseed - **Live demo:** https://styleseed-demo.vercel.app - **License:** MIT
