Prompt for your agent

Goal: Create an animated art piece entirely in code.
Setup: agents used in source: Claude; tools/MCPs stated: Salamander Grand Piano samples.
Steps:
1. Prompt for the scene and style (e.g. a riso-print train journey drawn entirely in JavaScript).
2. Have it write the score and use open-source instrument recordings on top for better sound.
3. Variant: plot wallpapers from real scientific data and code, with no image generation.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
