I thought the Opus 5.5 design posts were all jokes. They're not. It's GOATed at design. I asked it to make a product showreel for Reactive Resume. It built this entire video in Remotion, in ONE prompt. The setup: → Opus 5.5, max effort → Claude desktop app → No skills, no templates, no design brief → Just my project repo It read the codebase, figured out what the product does, and decided what was worth showing. A launch video like this used to mean days in After Effects or paying a motion designer. Now a solo open-source maintainer can do it in an afternoon. Full prompt in the replies ⬇️
