📌 Version

Current release: v1.1.0 · See the Changelog · All releases

No build tools, dependencies, or runtime required — this is a pure instruction & knowledge layer for AI agents.

✨ What It Does

🚀 Quick Start

Option A — Install with npx (recommended)

Drop the kit into any project, no clone needed:

npx ux-ui-agent-skills init          # full kit into the current folder
npx ux-ui-agent-skills add tokens taste design-systems   # just some areas
npx ux-ui-agent-skills list          # see all areas

Flags: --force (overwrite existing files) · --dry (preview, change nothing).

Option B — Clone

git clone https://github.com/plugin87/ux-ui-agent-skills.git
cp -r ux-ui-agent-skills/ your-project/

Then start using — open the project in Claude Code or any Claude-powered IDE. CLAUDE.md loads automatically, activating the agent persona with full access to every tokens / components / taste / design-system file and the runnable /skills.

"Design a notification component with all states and accessibility"
"Review this login page against WCAG 2.2 and Nielsen's heuristics"
"Generate React + Tailwind code for a data table with sorting and pagination"
"Create a color token palette for a fintech brand using blue as the primary"
"Audit this form for accessibility issues — give me a prioritized findings table"
"Write the empty state and error copy for the onboarding flow"
"Spec the motion for the modal open/close with reduced-motion fallback"

🎮 How to Use

There are three ways to drive the kit. Use whichever fits the moment.

1. Just ask (zero commands)

CLAUDE.md loads automatically, so plain requests already route to the right knowledge. Describe what you want and the agent self-routes via the built-in Request Router:

"Generate a Svelte button with all states and dark mode"
"Make this landing page feel like Linear"
"Migrate our Material 3 colors into this token system"

2. Run a skill explicitly (/skill)

Type a slash command to invoke a capability directly. Each skill loads only the files it needs and can run its own scripts.

/design-code  a pricing card in Vue, dark-mode aware
/apply-aesthetic  stripe   →  make the dashboard feel like Stripe
/a11y-audit  this checkout form
/migrate-design-system  from Material 3 to our tokens

3. Run the scripts (real, no dependencies)

Plain python3 — useful in the terminal or CI:

python3 scripts/validate_tokens.py                 # validate token JSON + alias refs
python3 scripts/contrast.py "#1d1d1f" "#ffffff"    # WCAG contrast ratio + pass/fail
python3 scripts/design_systems.py list             # browse the 138-system library
python3 scripts/design_systems.py show apple        # inspect one system
python3 scripts/scaffold_component.py "Date Picker" # emit a component spec stub

Typical flow

1. /apply-aesthetic linear      → set the visual direction (tokens re-pointed)
2. /design-component Combobox    → spec it with states + a11y
3. /design-code  Combobox in React + Tailwind   → production code
4. /a11y-audit                   → verify contrast, keyboard, focus
5. /design-review                → score + findings before ship

Tip: skills compose. apply-aesthetic always re-verifies contrast through a11y-audit; redesign calls design-review + a11y-audit automatically.

[!NOTE]
The design-taste layer (taste/) and the 138-system library (design-systems/library/) set visual direction; the system (tokens, components, accessibility) keeps it correct. Taste serves the Aesthetics tier and never overrides accessibility. Skills under .claude/skills/ run with agent permissions — review before use.

🎨 Token Architecture

The design token system follows a 3-tier hierarchy using the DTCG standard:

┌─────────────────────┐     ┌─────────────────────┐     ┌─────────────────────┐
│  COMPONENT TOKENS   │ ──► │  SEMANTIC TOKENS    │ ──► │  PRIMITIVE TOKENS   │
│  button-bg-primary  │     │  action.primary     │     │  blue.600 = #2563EB │
│  (use in code)      │     │  (use in design)    │     │  (raw palette)      │
└─────────────────────┘     └─────────────────────┘     └─────────────────────┘

Dark mode works by swapping semantic tokens — primitives stay the same.

🧰 Supported Frameworks — any

The Framework Adapter Protocol defines a universal token→framework contract, so the agent can target a stack even with no dedicated file (it generates an adapter on demand).

Full references

Concise adapters — Vue 3 · Svelte 5 · Angular · SolidJS · Web Components (Lit) · React Native · Flutter · Jetpack Compose · vanilla CSS · CSS-in-JS (emotion/vanilla-extract/Panda)

🔌 Design-System Interop — any

Adopt, build on, or migrate between external design systems via a role-based crosswalk (interop-protocol + crosswalk). Curated tables: Material Design 3 · Apple HIG · Fluent 2 · Carbon · shadcn/ui · Radix (others derived on demand). Plus a library of 138 brand-grade design systems (apple, linear, stripe, vercel, notion, spotify, tesla…) under design-systems/library/.

♿ Accessibility Standards

All outputs follow WCAG 2.2 Level AA as a minimum:

• ✅ Color contrast: 4.5:1 (text), 3:1 (UI components)
• ✅ Keyboard navigable with visible focus indicators
• ✅ Screen reader compatible with proper ARIA roles and live regions
• ✅ Touch targets: 24×24px minimum (WCAG 2.5.8)
• ✅ WCAG 2.2 criteria: Focus Not Obscured, Target Size, Accessible Authentication

⭐ Design Review Output

When reviewing designs, the agent scores across 6 weighted dimensions:

Findings are categorized: 🔴 Critical (must fix) → 🟠 Major (fix this sprint) → 🟡 Minor (when convenient) → 🔵 Enhancement (backlog).

🛠️ Customization

This is a starter kit — make it yours:

• Brand colors — edit tokens/colors.json primitives, then update semantic references
• Typography — swap font families in tokens/typography.json and framework files
• Components — add new components following the existing spec format in components/
• Frameworks — add new framework files in frameworks/ (e.g., vue.md, flutter.md)
• Workflows — adapt review rubrics and checklists in workflows/ to your team's process

📋 Requirements

• Claude Code CLI or any Claude-powered IDE
• A Claude model with sufficient context (Sonnet, Opus, or Haiku)
