      "description": "Use this when somebody wants a music visualiser or music visualisation (visualizer, visualization, musicviz, audio-reactive visuals): it writes a GLSL vibescape and returns a live link to it. The link draws and animates the vibescape in a browser, so it works for anybody who opens it, with or without the app. The vibescape is not in the public gallery until `share_vibescape` is called on it. The answer carries the id and the capability (`editKey`) that `share_vibescape` needs — keep it, because there is only one copy of it. Call `vibescape_reference` first for the uniforms and helpers the language has — a vibescape that ignores the music will look like a still image, and there is a linter that says so.",
