Ein UI Skill for Claude Code

Claude Code skill providing guidance for Ein UI, a liquid glass morphism component library for React/Next.js.

What's New: OKLCH Color Palette System

This skill now enforces custom OKLCH color palettes derived from the user's brand/anchor color. No more generic cyan/purple "AI slop" — every project gets a unique, professional palette.

How It Works

1. The skill prompts for the user's anchor color before any design work
2. A 7-color OKLCH palette is generated using a chroma-varying algorithm
3. All components, glows, and backgrounds reference the palette via CSS variables (--color-1 through --color-7)
4. Zero hardcoded colors — the entire theme changes by updating one anchor color

Color Science

The palette uses chroma tapering — peak saturation at the anchor lightness, naturally fading toward light and dark extremes. This is the key difference between professional and AI-generated palettes.

Anchor: oklch(0.60 0.15 280)  →  Full chroma at mid-lightness
Light:  oklch(0.95 0.045 280) →  Subtle, not neon
Dark:   oklch(0.20 0.045 280) →  Rich, not muddy

Use the OKLCH Color Palette Generator or the built-in algorithm in the skill to generate palettes.

Installation

Option 1: Personal Skill (Recommended)

Install as a global skill available in all your projects:

# Clone and copy to Claude Code skills directory
git clone https://github.com/unobtuse/einui-claude-skill.git
mkdir -p ~/.claude/skills/einui
cp -r einui-claude-skill/skills/einui/* ~/.claude/skills/einui/

After installation, /einui will be available in Claude Code.

Option 2: Local Plugin

Install as a Claude Code plugin:

# Clone to local plugins directory
mkdir -p ~/.claude/plugins/local
git clone https://github.com/unobtuse/einui-claude-skill.git ~/.claude/plugins/local/einui

Then enable in ~/.claude/settings.json:

{
  "enabledPlugins": {
    "einui@local": true
  }
}

Option 3: Project-Level

For a single project only:

mkdir -p .claude/skills/einui
cp -r einui-claude-skill/skills/einui/* .claude/skills/einui/
