What it does
Shader for Interfaces helps an agent choose between CSS, SVG, Canvas 2D, Three.js/WebGL2 and vgpu/WebGPU, write an effect in GLSL or WGSL and wire it into a page. References cover particles, texture distortion, data surfaces, color, React Three Fiber integration, performance and accessibility. The effect stays a backdrop: text and controls live in the DOM, `prefers-reduced-motion` is supported, and the result is checked on the live page on desktop and mobile. Version 0.1.0 shipped on August 30, 2026.
Who it is for. Frontend developers and design engineers who need a restrained shader behind a header or card instead of a full-screen demo.
Good fit when
- You need to decide whether CSS is enough or WebGL is unavoidable.
- A pointer-reactive backdrop behind a pricing block must respect reduced motion.
- A `ShaderMaterial` shader renders black after a window resize.
- A small dataset is drawn as a GPU surface with a legend and a text alternative.
Not a fit when
- You need feedback simulations, render graphs or renderer migrations: out of scope.
- You want a full-screen game or a heavy 3D scene.
- The project has no browser surface: checks run on a live page.
Example request
Use shader-for-interfaces to add a restrained WebGL backdrop behind the pricing header, honor reduced motion and verify the page on mobile.Limitations
The skill handles focused effects: one draw, modest particles and fixed quality caps. Dependent render targets, simulations and adaptive quality controllers are out of scope, and the agent should say so. Version 0.1.0, an early project. The last commit is from September 2026. Effects need a browser with WebGL2 or WebGPU support, and you must verify the no-GPU fallback yourself. The skill reminds the agent about fallbacks and accessibility but does not guarantee them.
How to disable. Remove the skill folder with the Skills CLI or by hand from the agent's skills directory, then start a new task.
FAQ
How do I install for all agents?
Add `--global` to the Skills CLI install command and the skill reaches supported agents on the machine.
Is Node.js required?
Only for the Skills CLI, vgpu tooling and pixel checks. The skill instructions themselves have no dependencies.
Can I use it for commercial work?
Yes, the MIT license allows commercial and client work. Scope is set by technical complexity.
Which renderers does it cover?
CSS, SVG, Canvas 2D, Three.js with WebGL2 and GLSL, and vgpu with WebGPU and WGSL. The choice depends on the task.
What should I prepare?
Name the project, the effect's role, interaction states, target devices, design tokens and for data the units, domain and missing-value behavior.

README in short
The skill is portable across agents and frameworks, and vgpu is added only when the renderer decision justifies it. Mention targets, browsers and design tokens in your request.
