## What it does

The skill guides an agent to layer cursor-driven fluid ripples over existing images. It renders the source graphic through a `Shader` root containing `ImageTexture` and `CursorRipples`. The original semantic `<img>` stays beneath the canvas at z-index `0`. That keeps the layout accessible and delivers an immediate fallback if WebGPU is absent or motion is reduced.

Old reveal implementations must go. Leaving radial masks, duplicated hover images, or custom `requestAnimationFrame` listeners alongside the shader creates coordinate drift and wastes GPU cycles. In Vite setups, never put `shaders` in `optimizeDeps.exclude` because its CommonJS dependencies require pre-bundling.

Interactive links and copy stay above the canvas, while the shader layer receives `pointer-events: none`. The library listens to pointer events globally, so manual event tracking is unnecessary. Note that commercial releases require verifying current Shaders license terms.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill shaders-cursor-ripples -a codex
```

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills shaders-cursor-ripples
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**

npx skills add MengTo/Skills --skill shaders-cursor-ripples -a gemini-cli
```

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

### Windsurf (Devin Desktop)

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

### OpenCode

## When to use it
- replace CSS spotlight reveals with WebGPU water ripple distortion
- keep accessible image fallbacks when WebGPU fails or motion is reduced
- clean up redundant pointer listeners and radial gradient mask layers
- configure lazy loading for shader code without breaking Vite pre-bundling

## Example prompts
- Add cursor ripples to the hero image using Shaders ImageTexture and CursorRipples components.
- Replace the drifting CSS spotlight mask with an interactive WebGPU ripple effect.
- Set up a lazy-loaded CursorRippleShader with prefers-reduced-motion fallback.

description: Add cursor-following fluid WebGPU distortion over an existing image with the Shaders library's ImageTexture and CursorRipples components. Use when a hero, gallery, or media panel needs a water-ripple mouse effect; when replacing a drifting CSS spotlight or flashlight reveal; or when a prompt says to borrow only the shader interaction from a Shaders.com reference while preserving the current brand, image, copy, and layout.

# Shaders Cursor Ripples

## Core Contract

1. Preserve the existing page, content, and semantic image.
2. Install `shaders` and import from the active framework subpath.
3. Render the source image through one `Shader` canvas.
4. Place `CursorRipples` after `ImageTexture` so it post-processes that image.
5. Keep `toneMapping="aces"` on the root.
6. Let Shaders track the cursor. Remove custom spotlight coordinates, radial masks, duplicated reveal images, and pointer animation loops.
7. Keep one real image beneath the canvas as the accessible loading and WebGPU fallback.
8. Disable the shader for reduced motion and unsupported WebGPU.
9. Lazy-load the shader code so the library does not inflate the initial page bundle.

When the user asks for only the shader effect, do not copy a reference's ribbon, blob, glow, typography, layout, copy, colors, or identity. Do not substitute the Shaders `Water` component: `CursorRipples` is the interactive image-displacement effect.

## Inspect Before Editing

- Find the real media wrapper, image URL, crop, overlays, z-index, and existing motion.
- Confirm the wrapper has a non-zero rendered width and height.
- Search for old reveal code such as `data-reveal-hover`, `mask-image: radial-gradient`, duplicated images, `requestAnimationFrame`, and manual pointer listeners.
- Preserve unrelated parallax or entrance motion unless it conflicts with the shader canvas.
- Check the installed `shaders` version and current framework API when the package may have changed.

## Install

```bash
npm install shaders
```

Import from `shaders/react`, `shaders/vue`, `shaders/svelte`, or `shaders/solid`. For Vite projects, never add `shaders` to `optimizeDeps.exclude`; its CommonJS dependencies need Vite pre-bundling. No `optimizeDeps` entry is normally required.

Before a commercial release, verify the current Shaders license terms.

## Required Composition

Keep the component order and values below:

```tsx
<Shader toneMapping="aces">
  <ImageTexture url={imageUrl} objectFit="cover" />
  <CursorRipples decay={7.3} radius={0.6} />
</Shader>
```
