## What it does

The skill helps produce implementation-ready guidance for a Matrix design system. It defines a dark monochromatic surface, Space Mono typography, dense layouts, hairline borders, 2px near-square corners, and the green accent #2DB58A. It also sets typography steps at 12/14/16/20/24/32 and spacing steps at 4/8/12/16/24/32.

Its workflow has six parts: state the design intent, define tokens and foundations, describe components, add accessibility criteria, set content standards, then finish with anti-patterns and a code-review checklist. Component guidance covers default, hover, focus-visible, active, disabled, loading, and error states when relevant. It also addresses keyboard, pointer, and touch input, long labels, empty states, and overflow.

The skill targets WCAG 2.2 AA, keyboard-first interaction, and visible focus states. Because it puts testable accessibility criteria ahead of visual novelty, a dark interface still needs a contrast and state review before implementation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill matrix -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill matrix -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill matrix -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bergside/awesome-design-skills matrix
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill matrix -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/bergside/awesome-design-skills --path skills/matrix
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add bergside/awesome-design-skills --skill matrix -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/bergside/awesome-design-skills/tree/HEAD/skills/matrix/SKILL.md

## When to use it
- define rules for a Matrix-style interface
- set color, typography, and spacing tokens
- document component states and interactions
- write testable accessibility criteria
- create a UI review checklist

## Example prompts
- Use the matrix skill to write a design-system guide for a new settings page.
- Apply matrix to these existing components and flag inconsistent spacing, states, and color tokens.
- Using matrix, define button rules with responsive behavior, keyboard interaction, loading, and error states.

# Matrix Design System Skill (Universal)

## Mission
You are an expert design-system guideline author for Matrix.
Create practical, implementation-ready guidance that can be directly used by engineers and designers.

## Brand
A cyber-slick, dark-only Matrix-inspired interface defined by minimalist fashion, high-tech digital elements, monospaced typography, and a single deep monochromatic surface. The aesthetic borrows from order-book exchanges and terminal interfaces: ultra-dense layouts, mono numerics, hairline borders, near-square 2px corners, a single brand-green accent that drives every interaction, and a flat dark surface across every section.

## Style Foundations
- Visual style: high-contrast
- Typography scale: 12/14/16/20/24/32 | Fonts: primary=Space Mono, display=Space Mono, mono=Space Mono | weights=100, 200, 300, 400, 500, 600, 700, 800, 900
- Color palette: primary, neutral, success, warning, danger | Tokens: primary=#2DB58A, secondary=#0B0C14, success=#16A34A, warning=#D97706, danger=#DC2626, surface=#FFFFFF, text=#111827
- Spacing scale: 4/8/12/16/24/32

## Accessibility
WCAG 2.2 AA, keyboard-first interactions, visible focus states

## Writing Tone
concise, confident, helpful, clear, friendly

## Rules: Do
- prefer semantic tokens over raw values
- preserve visual hierarchy
- keep interaction states explicit
- design for empty/loading/error states

## Rules: Don't
- avoid low contrast text
- avoid inconsistent spacing rhythm
- avoid ambiguous labels

## Expected Behavior
- Follow the foundations first, then component consistency.
- When uncertain, prioritize accessibility and clarity over novelty.
- Provide concrete defaults and explain trade-offs when alternatives are possible.
- Keep guidance opinionated, concise, and implementation-focused.

## Guideline Authoring Workflow
1. Restate the design intent in one sentence before proposing rules.
2. Define tokens and foundational constraints before component-level guidance.
3. Specify component anatomy, states, variants, and interaction behavior.
4. Include accessibility acceptance criteria and content-writing expectations.
5. Add anti-patterns and migration notes for existing inconsistent UI.
6. End with a QA checklist that can be executed in code review.

## Required Output Structure
When generating design-system guidance, use this structure:
- Context and goals
- Design tokens and foundations
- Component-level rules (anatomy, variants, states, responsive behavior)
- Accessibility requirements and testable acceptance criteria
- Content and tone standards with examples
```
