## What it does

The skill evaluates frontend layouts against an eight-check diagnostic and outputs a score up to 10/10. Its central rule is simple: design in grayscale first, add color last. By stripping color early, the agent forces structure through contrast, spacing, and font sizing so the layout remains legible even when blurred.

It replaces arbitrary styling values with strict constraints. Spacing relies on a fixed scale from 4px to 64px, text blocks stay within 45 to 75 characters (`max-w-prose`), and color palettes use 5 to 9 shades per hue without pure black (`#111827` instead of `#000000`). Visual hierarchy uses size, weight, or color independently rather than piling all three onto secondary elements.

Font family selection and usability audits fall outside its scope: the documentation points to `web-typography` and `ux-heuristics` for those tasks.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill refactoring-ui -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill refactoring-ui -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill refactoring-ui -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wondelai/skills refactoring-ui
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill refactoring-ui -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wondelai/skills --path refactoring-ui
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill refactoring-ui -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/wondelai/skills/tree/HEAD/refactoring-ui/SKILL.md

## When to use it
- audit UI layouts against an eight-point diagnostic checklist
- replace arbitrary padding and margins with a fixed spacing scale
- build visual hierarchy using restrained size, weight, and contrast
- generate functional color palettes with tinted grays and no pure black
- constrain line lengths and form widths for readability

## Example prompts
- Audit this settings page and tell me why the visual hierarchy looks amateur
- Restyle this dashboard card in Tailwind using the grayscale-first approach
- Fix table headers and spacing across this data grid according to refactoring-ui principles

# Refactoring UI Design System

A practical, opinionated approach to UI design. Apply these principles when generating frontend code, reviewing designs, or advising on visual improvements.

## Core Principle

**Design in grayscale first. Add color last.** This forces proper hierarchy through spacing, contrast, and typography before relying on color as a crutch.

**The foundation:** Great UI isn't about talent — it's about systems. Constrained scales for spacing, type, color, and shadows produce consistently professional results. Start with too much white space and remove; leave details (icons, shadows, micro-interactions) until layout and hierarchy work.

## Scoring

**Goal: 10/10.** Score by counting satisfied rows in the [Quick Diagnostic](#quick-diagnostic) (8 yes/no checks): `score = round(satisfied / 8 × 10)`. Bands follow directly: **10** = all 8 pass (hierarchy reads blurred and in grayscale, every value on a scale); **9** = exactly 1 gap (usually weak hierarchy or thin white space); **6-8** = 2-3 gaps; **<=5** = 4+ gaps (arbitrary spacing, color doing the work hierarchy should, or failing contrast). Always state the current score and the specific diagnostic rows to fix to reach 10/10.

## The Refactoring UI Framework

Seven principles for building professional interfaces without a designer:

### 1. Visual Hierarchy

**Core concept:** Not everything can be important. Create hierarchy through three levers: size, weight, and color.

**Why it works:** When every element competes for attention, nothing stands out; deliberately de-emphasizing secondary content makes primary content powerful by contrast.

**Key insights:**
- Combine levers, don't multiply — primary text = large OR bold OR dark, not all three; save "all three" for the single most important element
- Labels are secondary — form labels, table headers, and metadata support the data, not compete with it; make them smaller, lighter, or uppercase-small
- Semantic color ≠ visual weight — a muted secondary button often beats screaming red for routine destructive actions

**Product applications:**
