 "summary": "Use the cortico-world-vtuber project to drive a Live2D avatar, speech and subtitles.",
 "who": "A streamer or creator who wants an AI VTuber that speaks and animates on stream.",
 "problem": "Connecting a Live2D model, voice output, subtitle timing and a stream overlay into one AI character takes many separate tools.",
 "outcome": "A Cortico World that drives a Live2D model through VTube Studio, speaks through streaming TTS, times subtitles with a forced aligner and pushes the overlay into OBS.",
 "steps": [
  "Clone the cortico-world-vtuber repository from https://github.com/Pal-AI-Lab/cortico-world-vtuber, since it is kept outside the Cortico main tree.",
  "Install its dependencies following the instructions in that repository. (inferred, check the README)",
  "Set up VTube Studio with your Live2D model.",
  "Configure the streaming TTS and forced aligner as that repository describes.",
  "Add the overlay to OBS and start the bot."
 ],
 "agent_prompt": "Clone https://github.com/Pal-AI-Lab/cortico-world-vtuber and set it up as a Cortico World for a Live2D model in VTube Studio. Expected output: a running World that shows subtitles in the OBS overlay. Verify that the subtitle timing lines up with the spoken audio.",
