## What it does

The skill works in two directions. Analysis scripts walk your CSS and report a colour inventory, font sizes, spacing distribution, inconsistencies, plus contrast ratios, focus indicators and touch target sizes against WCAG. Generation scripts take a seed colour or a JSON spec and produce a palette, a typographic scale, a token file or a component template.

Everything runs as TypeScript scripts: `analyze-styles.ts`, `extract-tokens.ts`, `analyze-accessibility.ts`, `generate-palette.ts`, `generate-typography.ts`, `generate-tokens.ts`, `generate-component.ts`. Tokens come out as css, scss, tailwind, style-dictionary or tokens-studio. Components target React, Vue, Svelte and plain HTML/CSS, with tailwind among the styling options.

You need Deno installed with `--allow-read` and `--allow-write` permissions. No Deno, no scripts — check that before you install anything else. The audit mode also expects real CSS or design files to read, so it earns its place once there is code to review.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill frontend-design -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill frontend-design -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill frontend-design -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jwynia/agent-skills frontend-design
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill frontend-design -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jwynia/agent-skills --path skills/tech/frontend/design/frontend-design
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill frontend-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/jwynia/agent-skills/tree/HEAD/skills/tech/frontend/design/frontend-design/SKILL.md

## When to use it
- spot colour and spacing drift across a stylesheet
- extract design tokens from a legacy codebase
- build a palette from a single seed colour
- set up a type scale with a clear hierarchy
- check contrast and focus states before shipping

## Example prompts
- analyze styles.css and show me where colours and spacing drift
- generate a warm palette from #2563eb and output it as css
- generate a Button component for react with tailwind styling

# Frontend Design

Create distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. This skill combines design philosophy guidance with practical TypeScript tooling for analyzing existing designs and generating design system artifacts.

**Core Principle**: Choose a clear aesthetic direction and execute it with precision. Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.

## When to Use This Skill

**Use when**:
- Building web components, pages, or applications
- Auditing existing CSS for design inconsistencies
- Extracting design tokens from legacy codebases
- Generating color palettes and typography systems
- Creating component templates across frameworks
- Checking accessibility compliance for design elements

**Don't use when**:
- Simple text content changes
- Backend-only work
- Non-visual functionality

## Prerequisites

- **Deno** runtime (for script execution)
- Optional: Existing CSS/design files for analysis
- Optional: Design tokens file for reference

## Quick Start

This skill operates in three modes:

### 1. Analyze Mode
Audit existing styles, extract tokens, check accessibility.

```bash
# Audit CSS for design patterns and inconsistencies
deno run --allow-read scripts/analyze-styles.ts styles.css

# Extract design tokens from existing CSS
deno run --allow-read scripts/extract-tokens.ts ./src --format css

# Check accessibility (contrast, focus states)
deno run --allow-read scripts/analyze-accessibility.ts component.tsx
```

### 2. Specify Mode
Create JSON specifications defining what to generate. See `assets/` for schema examples.

### 3. Generate Mode
Create palettes, typography systems, tokens, and components.

```bash
# Generate a color palette
deno run --allow-read --allow-write scripts/generate-palette.ts --seed "#2563eb" --theme warm

# Generate typography system
deno run --allow-read --allow-write scripts/generate-typography.ts --display "Playfair Display" --body "Source Sans Pro"
````
