What it does

When you ask for an animated, interactive hero visual or 3D-style background, this skill tells the agent to produce a single self-contained web page that draws live graphics on your graphics card using WebGL, with a headline and short line of text layered on top. It gives the agent a working reference file to copy the structure from, a menu of visual techniques to choose from, and a checklist to verify the result runs smoothly and resizes correctly. The output is a page you can open in a browser, not a static image.

Great for

  • Designers who want an animated hero section or landing-page background without writing shader code by hand
  • Front-end developers prototyping a real-time visual effect that they will later refine or port
  • Creators making generative art pieces that run in the browser

Skip it if

  • Users on older or low-power devices, since full-screen GPU animation can drain battery and run slowly (performance risk)
  • Projects that need a static, accessible, or print-ready layout, because the visual is the focus and motion-heavy pages can be hard for some people to read
  • Anyone expecting the skill to work outside a web browser, since its output is only a browser-based HTML page

Try asking

  • “Make a full-screen aurora-style animated hero with the headline 'Quiet Signal' over it”
  • “Create a raymarched 3D sphere scene as the background for my product launch page”
  • “Build a generative particle field in WebGL2 with a short tagline and a lime accent color”
  • “Turn this brand palette into an interactive shader background for our landing page”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Name the visual technique you want (shader field, 3D scene, particles) and the mood, so the agent skips the default guesses
  • Ask for a fallback message and check it on a device without WebGL2, since the skill requires graceful degradation
  • Keep the headline short (the skill caps it at about 14 characters per line) and review the animation frame rate on your own machine
