Design System Generator & Auditor

Your AI generates or audits design systems for visual consistency and style coherence. It extracts tokens from code, researches competitors, scores UI across dimensions, and produces design tokens, rationale docs, and interactive previews.

What is this skill?

Use this skill to generate or audit design systems, check visual consistency, and review PRs that touch styling. Use when generating or auditing a design system, checking visual consistency, or reviewing a PR that touches styling.

When to use

  • Starting a new project that needs a design system
  • Auditing an existing codebase for visual consistency
  • Before a redesign — understand what you have
  • When the UI looks "off" but you can't pinpoint why
  • Reviewing PRs that touch styling

  2. Examples

How It Works

Mode 1: Generate Design System

Analyzes your codebase and generates a cohesive design system:

1. Scan CSS/Tailwind/styled-components for existing patterns
2. Extract: colors, typography, spacing, border-radius, shadows, breakpoints
3. Research 3 competitor sites for inspiration (via browser MCP)
4. Propose a design token set (JSON + CSS custom properties)
5. Generate DESIGN.md with rationale for each decision
6. Create an interactive HTML preview page (self-contained, no deps)

Output: DESIGN.md + design-tokens.json + design-preview.html

Mode 2: Visual Audit

Scores your UI across 10 dimensions (0-10 each):

1. Color consistency — are you using your palette or random hex values?
2. Typography hierarchy — clear h1 > h2 > h3 > body > caption?
3. Spacing rhythm — consistent scale (4px/8px/16px) or arbitrary?
4. Component consistency — do similar elements look similar?
5. Responsive behavior — fluid or broken at breakpoints?
6. Dark mode — complete or half-done?
7. Animation — purposeful or gratuitous?
8. Accessibility — contrast ratios, focus states, touch targets
9. Information density — cluttered or clean?
10. Polish — hover states, transitions, loading states, empty states

Each dimension gets a score, specific examples, and a fix with exact file:line.

Mode 3: AI Slop Detection

Identifies generic AI-generated design patterns:

- Gratuitous gradients on everything
- Purple-to-blue defaults
- "Glass morphism" cards with no purpose
- Rounded corners on things that shouldn't be rounded
- Excessive animations on scroll
- Generic hero with centered text over stock gradient
- Sans-serif font stack with no personality

Examples

Generate for a SaaS app:

/design-system generate --style minimal --palette earth-tones

Audit existing UI:

/design-system audit --url http://localhost:3000 --pages / /pricing /docs
