## What it does

The skill describes duplicating the item sequence, then moving the track with a linear transform from 0 to -50%. Keep item widths stable to avoid a jump when the sequence restarts. A mask or fading edges can soften where the marquee enters or leaves a section.

The motion can pause or slow on hover when interaction calls for it. For `prefers-reduced-motion`, use a static arrangement or very slow movement. Avoid scrolling content people need to read carefully. Large shadows and filters on every moving item can also burden the CPU, so this skill advises against applying them across the track.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill marquee-loop -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill marquee-loop -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills marquee-loop
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill marquee-loop -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- loop a row of logos without a visible break
- present testimonials in a scrolling track
- build a marquee from screenshots or tags
- prevent jumps when the animation repeats

## Example prompts
- Create a logo marquee that loops without a visible break.
- Add a testimonials track and account for `prefers-reduced-motion`.
- Show these screenshots in a marquee that slows on hover.

# Marquee Skill

## Use When
- A design needs a seamless infinite loop for logos, testimonials, screenshots, tags, or short feature chips.

## Workflow
1. Duplicate the item sequence so the end and beginning match perfectly.
2. Animate the track with a linear transform from 0 to -50%.
3. Keep item widths stable to prevent jumps during the loop.
4. Mask or fade the edges when the marquee enters or exits a section.
5. Pause or slow the marquee on hover only when interaction is useful.
6. Respect prefers-reduced-motion with a static wrap or very slow movement.

## Guardrails
- Do not animate unique content that users must read carefully.
- Do not use large CPU-heavy shadows or filters on every moving item.
