## What it does

The skill produces HTML and CSS for a progressive blur at the top or bottom of the viewport. It builds the effect from several backdrop-filter layers, masks, and increasing blur values from 0.5px to 64px. Before generating the snippet, the agent confirms the side, area height, and z-index position relative to the UI.

Place `.gradient-blur` inside `<body>` near the top of the DOM, with visible content behind it. The backdrop-filter works on what sits underneath the layer. Keep `pointer-events: none` so the overlay does not block clicks. High blur values are GPU-heavy, so reducing the number of layers is the right check for low-end devices.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**

```

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

### Windsurf (Devin Desktop)

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

### OpenCode

## When to use it
- add a soft blur along the top edge of a page
- create a bottom gradient blur over visible content
- tune blur strength through CSS layers
- place the overlay below modals but above page content

## Example prompts
- Add a bottom progressive blur to the page with a height of 65% and explain where `.gradient-blur` belongs.
- Create a top progressive blur for this interface and keep its `z-index` below the modal.
- Reduce the progressive blur layers for a low-end device. Keep `pointer-events: none` so clicks pass through.

# Progressive Blur Skill

## Workflow
1. Confirm placement (top or bottom), height, and z-index relative to UI.
2. Provide the matching snippet and a short usage checklist.
3. Offer only targeted tweaks (height, blur steps, direction, opacity stops).

## Usage checklist
- Insert the HTML inside `<body>`.
- Keep the `.gradient-blur` element near the top of the DOM.
- Ensure the background behind it exists (backdrop-filter blurs what is behind).
- Adjust `z-index` to sit above content but below modals.
