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.
