What it does

Webgl Experience is an agent skill from nexu-io/open-design. A full-screen, real-time WebGL/WebGL2 experience — animated shaders, 3D scenes, generative visuals, particle fields — rendered live on the GPU with a typographic overlay. Produced as a single self-contained index.html. Use when the brief asks for a "WebGL", "shader", "3D", "generative", "GPU", "interactive canvas", "hero animation", or "real-time visual" experience. OpenDesign serves this in powered-preview mode so the GPU stack actually runs.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Game Development, covering 3D graphics and WebGL and Shaders. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.

Credentials

Context cost

Webgl Experience loads about 903 tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 355 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~117
When it runs · the whole SKILL.md, loaded when a task matches: ~903

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

WebGL Experience Skill

Produce a single self-contained index.html that renders a real-time WebGL (or WebGL2) visual full-screen, with a clean typographic overlay on top.

Why this is a powered artifact

OpenDesign detects getContext('webgl2') / new Worker / SharedArrayBuffer and renders this file in powered preview — a cross-origin-isolated iframe with allow-same-origin. That means real Web Workers, SharedArrayBuffer, WASM, and the full GPU pipeline are available. You do not need to work around the opaque sandbox. Prefer webgl2 for modern features; fall back to webgl when the effect allows.

Resource map

webgl-experience/
├── SKILL.md      ← you're reading this
└── example.html  ← a working WebGL2 aurora-field reference (READ FIRST)

Workflow

Step 0 — Read the reference

Read example.html end to end. Note the shape: one full-viewport <canvas>, a fragment-shader draw loop on a fullscreen triangle, a DPR-aware resize, and a requestAnimationFrame tick. The overlay (kicker → h1 → sub) is pure HTML/CSS layered above the canvas via z-index.

Step 1 — Choose the visual

Pick ONE technique that fits the brief:

Fragment-shader field (default): domain-warped fbm noise, flow fields, plasma, gradients. Cheapest, always 60fps.
Raymarched scene: SDF spheres/boxes with soft shadows for a 3D hero.
Instanced geometry: thousands of points/quads driven by a vertex shader.
Post-processed image: sample a data-URI texture and distort/dither it.

Show full SKILL.md (167 more words)Show less

Step 2 — Build `index.html`

Keep it one file, zero external requests (inline the shader source; embed any texture as a data: URI). Powered mode allows CDN loads, but self-contained previews are faster and portable.
Always: alpha:false, DPR clamped to 2, viewport on resize, and a guard that shows a graceful message if the context is null.
Compile shaders with error logging (getShaderInfoLog) so a typo fails loudly, not silently black.

Step 3 — Overlay + brand

Map the two :root-level accent colors to the active DESIGN.md when one is present; otherwise use a restrained dark palette with a single vivid accent (the reference uses lime #63fe13).
Headline ≤ 14ch, one supporting line. Never cover the whole canvas — the visual is the hero.

Step 4 — Self-review (P0)

Renders continuously at ~60fps; the FPS badge updates.
No WebGL console errors; getError() clean after first frame.
Resizes crisply on window resize (no stretching / blur).
Readable overlay contrast over the brightest frame.
Degrades to a message (not a blank page) if webgl2 is unavailable.

A full-screen, real-time WebGL/WebGL2 experience — animated shaders, 3D scenes, generative visuals, particle fields — rendered live on the GPU with a typographic overlay.

When should I use Webgl Experience?

Webgl Experience fits situations like: the brief asks for a WebGL; interactive canvas; real-time visual experience.

How do I install Webgl Experience in Claude Code?

Run `npx skills add nexu-io/open-design --skill webgl-experience -a claude-code`. Or copy the skill folder (design-templates/webgl-experience in nexu-io/open-design) into .claude/skills/webgl-experience in your project. Claude Code loads it when a task matches its description.

How do I install Webgl Experience in Codex?

Run `npx skills add nexu-io/open-design --skill webgl-experience -a codex`. Or copy the skill folder (design-templates/webgl-experience in nexu-io/open-design) into .agents/skills/webgl-experience in your project. Codex loads it when a task matches its description.

Can I use Webgl Experience in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add nexu-io/open-design --skill webgl-experience -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/webgl-experience, .gemini/skills/webgl-experience, .github/skills/webgl-experience and .opencode/skills/webgl-experience in your project.

What does Webgl Experience need to run?

SKILL.md names no scripts, command-line tools or credentials: Webgl Experience is instructions for the agent only.

Does Webgl Experience access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Webgl Experience safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Webgl Experience use?

Webgl Experience is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Webgl Experience use?

About 903 tokens (SKILL.md is roughly 3.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Webgl Experience?

Skills that share tags, products or a category with Webgl Experience: Pixijs (RSamaium/CanvasEngine, 401 stars), New Experiment (Tresjs/tres, 3.8k stars), Shader Extract (cth9191/site-clone, 133 stars) and Typegpu (software-mansion-labs/skills, 291 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Webgl Experience?

nexu-io (a GitHub organization) maintains it in nexu-io/open-design, which has 100,100 GitHub stars. The repository holds 245 skills in this directory. The repository was last updated on October 9, 2026.
