Audio visualizer — how to make it with code and an AI agent

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.

The track made visible: spectrum, waveform or a shader that breathes with the bass.

Output: 16:9 · 1:1 · any length · Input: An audio file
