Prompting a Coding Agent to Build a Music Video Overnight
neoneye2 · reddit · 2026-09-29
The author shares the full prompt and workflow used to have a coding agent produce a music video:
- Assets (audio, isolated vocals, lyrics) live in assets/; the agent must draw artistic style from the author's triangle drawings and build an isometric triangle grid.
- The agent is told to study the structure of a previous music-video repo and to ask clarifying questions before starting.
- Mid-run the song was swapped for a better one, and the grid can be rotated, zoomed, and have its points shown/hidden.
- A final /goal instruction lets the agent finish the video while the author sleeps, committing files as it goes.
The takeaway is combining goal, assets, style reference and autonomous commits into one unattended generation task.
