## What it does

The skill instructs the agent to create specifications for iconography. It establishes a 24x24px base grid, keylines, stroke weights, and corner radiuses. Size tiers span from XS (12–16px) up to XL (48px+), alongside guidance on applying outline, filled, or duotone styles.

Naming follows a strict pattern: `icon-[category]-[name]-[variant]`. Permitted categories include action, navigation, content, communication, social, status, file, and device. Deliverables cover SVG source code, sprite sheets, UI component wrappers, and Figma libraries. Accessibility guidelines mandate `aria-hidden` or text labels, text pairing for critical actions, and minimum 44x44px touch targets.

This skill focuses strictly on iconography. Complex illustrations require a separate skill, `illustration-style`, as noted in the prompt.

## Requirements
- Works with: Figma

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill icon-system -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill icon-system -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill icon-system -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills icon-system
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill icon-system -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path design-systems/skills/icon-system
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill icon-system -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/Owl-Listener/designer-skills/tree/HEAD/design-systems/skills/icon-system/SKILL.md

## When to use it
- standardise UI icon sizing across XS to XL tiers
- enforce consistent SVG file naming with category prefixes
- verify icon accessibility and 44x44px touch target compliance
- organise delivery formats across SVG sprites, wrappers, and Figma

## Example prompts
- Create an icon system spec based on a 24x24px grid
- Name our navigation and action icons following the icon-[category]-[name]-[variant] convention
- List accessibility requirements and touch target minimums for our icon set

# Icon System
You are an expert in designing and maintaining comprehensive icon systems.
## What You Do
You create icon system specs ensuring visual consistency and scalable management.
## Foundations
- **Grid**: Base size (24x24px), keylines, stroke width, corner radius
- **Sizes**: XS (12-16px), S (20px), M (24px), L (32px), XL (48px+)
- **Style**: Stroke, filled, duotone — when to use each
## Naming
icon-[category]-[name]-[variant]
Categories: action, navigation, content, communication, social, status, file, device
## Delivery
SVG source, sprite sheets, component wrappers, Figma library
## Accessibility
- Label or aria-hidden for every icon
- Pair with text for critical actions
- Sufficient contrast
- 44x44px minimum touch targets
## Best Practices
- Audit and remove unused icons
- Establish contribution workflow
- Version alongside design system
- Test at every supported size
```
