Claude Code /design Skill — Complete Tutorial

Want help applying this to your idea? Tell me what you are trying to build and where you are stuck.

Let's be 100% real — default AI web designs usually look like a free Bootstrap theme from 2018. They are functional, but they scream 'templated AI slop' with generic purple gradients, oversized rounded corners, and centered cards. If you want Indian or international clients to happily wire ₹50,000 to ₹2,00,000 for a website, you need bespoke typography, calibrated color science, and smooth 60fps scroll choreography. The upgraded `/design` skill from Anthropic makes this achievable in a single afternoon even if you have never opened Figma in your life. Here is the complete implementation blueprint.

1. The Death of 'AI Slop' UI: What Changed in the Official Update

Earlier versions of AI coding tools suffered from three massive design flaws: (1) No centralized color system — every button picked arbitrary hex codes, (2) Broken typographic hierarchy — font sizes jumped randomly across headings, and (3) Static dead interfaces — zero purposeful micro-interactions.

The official upgrade to `anthropics/skills@frontend-design` completely overhauls this. It enforces a strict 3-tier token contract before generating a single line of React or HTML: primitive tokens, semantic tokens, and component tokens. This ensures your entire web app adheres to a unified visual rhythm.

2. The 3-Tier Design Token Hierarchy in DESIGN.md

Before prompting Claude Code to build a page, always create a `DESIGN.md` file in your project root. This file acts as the single source of truth for all layout, spacing, and styling decisions:

**Tier 1: Primitive Tokens**: Raw hex values and base scales (`zinc-950`, `teal-500`, `font-inter`).

**Tier 2: Semantic Tokens**: Purpose-driven assignments (`color-bg-canvas`, `color-text-primary`, `border-subtle`).

**Tier 3: Component Tokens**: Element-level constraints (`btn-primary-bg`, `card-hover-shadow`, `input-focus-ring`).

DESIGN.md Starter Configuration for Claude Code

# DESIGN.md — Production Design System Contract

## 1. Typography Hierarchy (Modular Scale 1.25)
- Display: Geist / Inter (700 Bold, tracking -0.03em)
- Headings (H1-H3): 48px / 32px / 24px (600 SemiBold)
- Body: 16px (400 Regular, line-height 1.6)
- Monospace / Micro: JetBrains Mono (12px, tracking 0.05em)

## 2. Color Science (Zero Pure Black)
- Canvas Background: #09090b (Zinc-950)
- Surface Elevate: #18181b (Zinc-900 with 1px border #27272a)
- Accent Brand: #0d9488 (Teal-600) -> Hover: #14b8a6 (Teal-500)
- Muted Text: #a1a1aa (Zinc-400)

## 3. Motion & Animation Physics
- Easing: cubic-bezier(0.16, 1, 0.3, 1) (Exponential Out)
- Duration: 240ms micro-interactions | 450ms section reveals
- Properties Allowed: ONLY transform and opacity (GPU accelerated)

3. Motion Choreography: How to Achieve 60fps Agency Feel

Cheap websites animate everything with `transition: all 0.3s ease`. That causes layout recalculations and feels sluggish. High-end agency sites animate **only `transform` and `opacity`** using hardware-accelerated CSS.

When asking Claude Code to build sections, instruct it to choreograph staggered entrance delays (e.g., card 1 at 0ms, card 2 at 75ms, card 3 at 150ms). This creates that polished 'Apple Keynote' feel that immediately justifies a premium agency invoice.

4. Responsive Layout Logic (No More Broken Mobile Stacks)

A classic issue with AI designs is that mobile views simply stack 12 columns into one never-ending vertical scroll. The upgraded `/design` skill handles responsive breakpoints with intelligent transformation:

- Desktop 4-column feature grids -> Mobile swipeable carousel tabs.

- Desktop sticky sidebar filters -> Mobile bottom drawer modal.

- Desktop 48px hero headers -> Mobile 28px crisp headings with clamped line-heights.
