## What it does

This skill instructs AI assistants to use Iconify Solar Duotone Bold as the standard icon set. It enforces consistent sizing across grouped components and pairs glyphs with labels on controls, navigation bars, and feature cards.

Duotone rendering relies on balanced opacity. Secondary fills must reinforce the main glyph silhouette, while stroke weights and hues match the underlying background contrast. The instructions explicitly warn against using standalone icons for unfamiliar actions.

Compatibility breaks if you blend different aesthetics: mixing Solar Duotone Bold with unrelated outline icons inside the same control cluster is strictly prohibited.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill solar-duotone-bold -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill solar-duotone-bold -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill solar-duotone-bold -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills solar-duotone-bold
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill solar-duotone-bold -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/web-design/solar-duotone-bold
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill solar-duotone-bold -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/MengTo/Skills/tree/HEAD/agent-skills/web-design/solar-duotone-bold/SKILL.md

## When to use it
- style component navigation using Solar Duotone Bold icons
- adjust duotone fill opacity to maintain glyph legibility
- align icon dimensions across grouped interface elements
- pair unfamiliar action icons with descriptive text labels

## Example prompts
- Build a feature grid using Solar Duotone Bold icons paired with clear labels
- Update the sidebar navigation buttons to use the Solar Duotone Bold icon family
- Adjust the duotone opacity and stroke contrast for icons on this dark surface

# Solar Duotone Bold Skill

## Use When
- A UI needs cohesive icons with a richer look than generic outline icons.

## Workflow
1. Use Iconify Solar Duotone Bold as the default icon family.
2. Keep icon sizes consistent within a component group.
3. Pair icons with clear labels for navigation, controls, and feature cards.
4. Use duotone opacity intentionally so secondary fills support the main glyph shape.
5. Match stroke, fill, and color treatment to the surrounding surface contrast.

## Guardrails
- Do not mix Solar Duotone Bold with unrelated outline icon families in the same control set.
- Do not rely on icons alone for unfamiliar actions.
