Dev generates full animated short with a single prompt using Opus 5.5 Dynamic Workflows

Daniel Mcateer demoed Claude Opus 5.5 combined with Claude Code's Dynamic Workflows: a single core prompt let the model autonomously produce a complete animated short on the theme of using "Ultracode" and "Dynamic Workflows" in Claude Code without burning through usage quota. The run took about 6.5 hours and 121 agent runs, consuming nearly 30% of his weekly allowance. Mcateer also shared the full reusable prompt.

Confirmed

The author posted the same demo multiple times with consistent content: an animated short generated via Opus 5.5 + Claude Code Dynamic Workflows
The core prompt is a single sentence asking Claude to make an animation about Opus 5.5's efficiency in Claude Code, in a film-production style
Per the author, every pixel of the video was generated by the model via Dynamic Workflows
Actual cost: 6.5 hours, 121 agent runs, nearly 30% of weekly quota consumed
The full prompt is public for reuse; workflow highlights include enabling ultracode reasoning mode

Why it matters

The demo showcases Dynamic Workflows' capability on long-horizon, multi-agent autonomous creation: from one prompt to a finished film with no human intervention
It also reveals the resource cost of such heavy tasks (nearly a third of weekly quota), a useful cost reference for anyone attempting reproduction
Sharing the full prompt lowers the barrier for community reproduction and derivative work
