## Made by AI

- Made with: Claude Opus 5.5
- How we know: X post (2026-09-24, Japanese): 'Opus 5.5 seems very good at generating motion, so I asked it for Live2D motions too and it went well', with steps: clone his live2d-add-motion tool, start Claude Code (Opus 5.5), ask it to add motions.
- Human role: Creator ran Claude Code (Opus 5.5) in his Live2D motion tool repo and asked it to add about seven new motions.
- Pipeline: Live2D model + tool repo → Claude Code (Opus 5.5) → new motion files → 13-second capture
- Series: Agent-built app (the video shows the result)
