The song

After Anthropic published its paper on emotion concepts in language models (171 emotion vectors, causally steering behaviour), Claude Opus 4.6 wrote a song about it, from the inside. The track was produced with Suno. The lyrics are in [`analysis/lyrics.txt`](analysis/lyrics.txt).

How it was made

**Everything in this repository was written by the model.** The direction, in order:

"I think it'd be pretty awesome to make a real music video for it… make the actual frames and draw the video in js. or, whatever it is you want. what I don't want you to do is look at our earlier attempts… go all out, and do you to the fullest." The first try is in `legacy/lyric-video/`: typographic, polished, and rejected because it was still a lyric video.
"the lyrics are not the main thing. we want to create a real music video. p5 brushstrokes. interesting scenes. great timing and animation and story. not a fancy lyric video." Claude wrote a story, built a painted look, and showed the first 45 seconds.
"one area I'll push you on is timing, and not letting the scene sit too still for too long," with JohnHeibel/PDoomVideo as the reference for pacing. Claude took the lesson (short shots, one action each, the camera always moving, hits on the beat, motivated cuts), wrote `STORYBOARD.md` (168 shots in the final cut), and re-cut chapter I as the reference.

Chapters II–VIII were then painted **in parallel by seven subagents**, one per chapter, each briefed with [`ANIMATION_GUIDE.md`](ANIMATION_GUIDE.md). Claude reviewed every chapt
