# Topology — component for generative & ascii (html)

> **For AI agents:** find the right skill in one call — `curl -s "https://skills.varg.ai/api/search?q=<what the person wants>"` returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the use-case page.

## Prompt that renders it frame-exact

Use the Vanta.js Topology effect (https://www.vantajs.com/?effect=topology, MIT, source github.com/tengbao/vanta/blob/master/src/vanta.topology.js) as a slow, textured full-frame background under titles or data callouts. It runs on p5.js: load p5 1.x (vantajs.com uses 1.1.9) and vanta@0.5.24/dist/vanta.topology.min.js, then mount VANTA.TOPOLOGY with mouse, touch and gyro controls off. The image builds up stroke by stroke, so frame N depends on every frame before it: seed Math.random before init, call effect.p5.noLoop(), and per video frame call effect.p5.redraw() 60/fps times, in order from frame 0. Pre-roll a second or two of draws before the scene starts if you want it already textured. Set color and backgroundColor from the brand palette.
