The underground base
One room per stage of a video pipeline, built from one prompt.
01 / What it was
On a live stream, the builder laid out a video pipeline as a chain of rooms dug into a mountain: branding, reference videos, requirements, editing, publishing. Then a frontier model was asked, from a terminal inside the game, to turn it into a proper underground base.
About 35 minutes later it was there, with rooms, monitors and desks. Each room then got its own Hermes profile, so its memory and skills stay apart from the others.
02 / How it worked
- Room = stage = agent: one Hermes profile per room.
- The model wrote the build as a data pack, loaded with /reload.
- Each room has its own monitor walls for its part of the work, for example a board of reference videos or a review page for a cut.
- Work moves by walking: you finish in one room and take it to the next.
03 / What we saw
It was fast to make, but not smooth: the rooms first came out in the wrong order, one cave was duplicated, the game crashed several times, and one agent's research came back poor. The sessions kept running through each crash.
04 / Where it led
It became the main example in our paper Rooms, Not Windows, and the same one-prompt idea built a robot lab two days later.

We just go to that room and just start building / And when we're done, then we just leave that room

Which is a hermes profile that has its own memory

So the order is wrong with the agents are fixing that
