## What it does

This skill establishes a structured workflow for interface planning and design system creation. It directs the AI assistant to gather technical constraints and establish visual hierarchy before writing frontend code.

Layouts start at 320px. The workflow enforces mobile-first scaling across 768px, 1024px, and 1440px breakpoints. Components follow atomic design principles, organizing elements into basic atoms up to complete organisms. Accessibility rules follow WCAG 2.1 AA specifications, enforcing 4.5:1 text contrast, 3:1 interface element contrast, keyboard navigation, and semantic ARIA labeling.

Deliverables provide design tokens, component variant specifications, and performance budgets tied to Core Web Vitals. The skill assumes you need clear interface specifications before beginning frontend implementation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add DauQuangThanh/hanoi-rainbow --skill frontend-ui-ux-design -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/frontend-ui-ux-design/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/frontend-ui-ux-design/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add DauQuangThanh/hanoi-rainbow --skill frontend-ui-ux-design -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/frontend-ui-ux-design/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add DauQuangThanh/hanoi-rainbow --skill frontend-ui-ux-design -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/frontend-ui-ux-design/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install DauQuangThanh/hanoi-rainbow frontend-ui-ux-design
```

2. **Manually: put the files in place**
- File: `.github/skills/frontend-ui-ux-design/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add DauQuangThanh/hanoi-rainbow --skill frontend-ui-ux-design -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/DauQuangThanh/hanoi-rainbow --path skills/frontend-ui-ux-design
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/frontend-ui-ux-design/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add DauQuangThanh/hanoi-rainbow --skill frontend-ui-ux-design -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/DauQuangThanh/hanoi-rainbow/tree/HEAD/skills/frontend-ui-ux-design/SKILL.md

## When to use it
- generate atomic component libraries with states and variants
- audit interface specifications against WCAG 2.1 AA accessibility
- build mobile-first responsive layouts starting from 320px
- document design tokens and component specs for developer handoff

## Example prompts
- Design a responsive settings dashboard starting at 320px mobile width with dark mode tokens.
- Create an atomic component specification for our checkout form with WCAG 2.1 AA contrast checks.
- Generate handoff documentation and layout breakpoints for tablet 768px and desktop 1440px.

# Frontend UI/UX Design

## Overview

This skill enables creation of production-ready frontend UI/UX designs from research through implementation. Follow a structured design process that balances user needs, business goals, technical constraints, and accessibility requirements.

## Design Workflow

## 1. Understand Requirements

**Gather Context:**

- Project goals and success metrics
- Target audience and user personas
- Technical constraints (frameworks, browsers, devices)
- Brand guidelines and design language
- Accessibility requirements (WCAG level)

**Clarify Scope:**

- Type of deliverable (wireframes, mockups, design system, component library)
- Fidelity level (low, medium, high)
- Responsive breakpoints needed
- Browser and device support

### 2. Research & Strategy

**User Research:**

- Analyze user needs, goals, and pain points
- Review existing analytics or user feedback
- Identify key user journeys and scenarios
- Define information architecture

**For complete research process**: See [uiux-design-process.md](references/uiux-design-process.md) for detailed research, personas, journey mapping, and information architecture guidelines.

### 3. Design & Prototype

**Create Wireframes:**

- Start with low-fidelity layouts
- Focus on content hierarchy and structure
- Define user flows for key tasks
- Iterate based on feedback

**Apply Visual Design:**

- Define color palette (primary, secondary, semantic colors)
- Establish typography scale and spacing system
- Design components with variants and states
- Ensure visual hierarchy and consistency

**For design principles**: See [design-principles.md](references/design-principles.md) for visual hierarchy, consistency, simplicity, feedback, and error prevention guidelines.

**For design systems**: See [design-systems.md](references/design-systems.md) when building comprehensive design systems with design tokens, governance, and documentation.

### 4. Ensure Accessibility

**WCAG Compliance:**

- Minimum contrast ratios (4.5:1 for text, 3:1 for large text/UI)
- Keyboard navigation support
```
