| name | web-shader-extractor |
| description | Extract a real WebGL / WebGPU / Canvas / shader effect from a live webpage (e.g. an animated
gradient mesh, fluid/metaball, gaussian-splat scene, image distortion) and port it to a
standalone, dependency-light JS project you can run locally or drop into an HTML artifact. Use
when the user points at a site's visual effect and wants to reproduce/port/replay it, especially
complex GPU effects our vanilla recipes don't cover.

web-shader-extractor (install-on-demand companion)
This is a thin wrapper. The upstream skill has no open license, so motion-anything cannot
redistribute its code — it is fetched on demand instead. Everything below is motion-anything's own
description; the implementation lives upstream.
What it does
Locks onto a page's rendering surface (WebGL/WebGPU/Canvas), records shader / resource / render-graph
/ timing / input evidence, builds an evidence-matched local baseline, then projectizes it into a
standalone runnable. This is the right tool for the "复杂网页效果 (WebGL / 高斯泼溅)" need that our
2D compositor deliberately does not draw — see WEBGL.md.
How to invoke
- If not already installed, fetch it (one-time, needs network):
npx skills add https://github.com/lixiaolin94/skills --skill web-shader-extractor
- Then follow that skill's flow against the target URL / effect.
- Bring the extracted effect back as a background layer in an HTML artifact; motion-anything adds
the surrounding tasteful motion.
Note for maintainers
If lixiaolin94/skills adds a permissive license, vendor it here properly (like skills/web-clone)
so it ships offline with the product. Until then, keep this wrapper.
