I just packed my whole 3D workflow into one Claude skill.
i gave opus 5.5 one reference picture and said: build me a full teardown of this, every part in code.
the build:
> the picture set the look, every shell, gear and hose is three.js code
> opus matched its render to the picture side by side for 3 rounds before any video
> 260 tiny pistons, hoses, screws and wires sit under the big gears
> my first version just hovered, so now something comes apart every 2-3 seconds
> pull a leg and its servo bar flips to DETACHED
i built 7 of these in 2 days. the sims are live on my playground.
the skill, the playground and all 9 prompts 👇
