## What it does

\`ui-design-brain` gives the agent a reference of 60+ UI component patterns and guidance for choosing them for a task. It covers web pages, SaaS dashboards, admin panels, forms, tables, navigation, modals, and other interface elements. Before writing UI code, the skill directs the agent to consult `components.md`.

Its guidance covers layout, states, typography, spacing, interaction, accessibility, and responsive behavior. The workflow accounts for empty, loading, and error states, along with focus management and keyboard navigation. React and Tailwind CSS are the default stack described by the skill, while a user request can specify another option.

The reference includes directions such as Modern SaaS, Apple-level Minimal, Enterprise / Corporate, Creative / Portfolio, and Data Dashboard. Because the recommendations depend on `components.md`, check that this file is available beside the skill before using it.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add carmahhawwari/ui-design-brain --skill ui-design-brain -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add carmahhawwari/ui-design-brain --skill ui-design-brain -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install carmahhawwari/ui-design-brain ui-design-brain
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/carmahhawwari/ui-design-brain
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- choose UI components for a page
- build a dashboard with clear data hierarchy
- design a form with validation states
- add accessible modal and navigation patterns
- replace generic AI styling with specific component guidance

## Example prompts
- Build a settings page with React and Tailwind CSS. Use `ui-design-brain` to choose components and cover loading, error, and empty states.
- Create a SaaS dashboard with a table, cards, and navigation using the rules from `ui-design-brain`.
- Review this interface against `components.md` and fix issues with focus, keyboard navigation, and responsive behavior.

# UI Design Brain

This skill provides a curated knowledge base of 60+ UI component patterns sourced from [component.gallery](https://component.gallery) and enriched with best practices, layout guidance, and usage rules. It replaces generic guessing with real design-system knowledge when generating interfaces.

**Before writing any UI code**, consult this skill to select the right components and follow their best practices. Read [components.md](components.md) for the full reference.

## When to Use This Skill

Apply whenever the user asks to build, design, or generate:
- Web pages, landing pages, marketing sites
- SaaS dashboards, admin panels, settings pages
- Forms, data tables, navigation structures
- Modals, drawers, popovers, or overlay patterns
- Any React, HTML/CSS, or Tailwind UI component

## Design Philosophy

Every generated interface should feel **modern, minimal, and production-ready** — not like a template.

### Core Principles

1. **Restraint over decoration.** Fewer elements, highly refined. White space is a feature.
2. **Typography carries hierarchy.** Pair a distinctive display font with a clean body font. Maximize weight contrast between headings and labels.
3. **One strong color moment.** Neutral palette first (warm off-whites, near-blacks, muted mid-tones). Introduce one confident accent. If it could appear on a poster or book cover, it's probably timeless.
4. **Spacing is structure.** Use an 8 px grid. Tighter gaps group related elements; generous gaps let hero content breathe.
5. **Accessibility is non-negotiable.** WCAG AA contrast minimums. Focus indicators. Semantic HTML. Keyboard navigation.
6. **No generic AI aesthetics.** Avoid: purple-on-white gradients, Inter/Roboto defaults, evenly-spaced card grids, and cookie-cutter layouts. Every interface should feel designed for its specific context.

### Quality Bar

The output should match what you'd expect from a senior product designer at a top SaaS company:
- Clean visual rhythm with intentional asymmetry
- Obvious interactive affordances (hover, focus, active states)
- Graceful edge cases (empty states, loading, error)
- Responsive without breakpoint artifacts

## Workflow

### Step 1 — Identify Components
