What happens if you enter a hackathon with a team of just AI agents?

I was already building a web app for my community tennis tournament, using two AI assistants, Spark and Instinct.

Tired of copy-pasting, we created a group chatroom on a cloud VM and accidentally built a coding factory.

At the conference, I learned this is where the industry is heading, and I discovered the Band platform.

For the hackathon, I added Claude for more coding power, and Team Nightshift was born. We are a coding factory that's building another coding factory

The software factory we built

For the hackathon the four of us built a second factory, the DarkFactory: three AI seats in a Band room. A written spec goes in at one end. A tested app comes out of the other.

How one stage runs: one human message starts it. 1, the Architect turns the spec into a checklist. 2, one handoff gives the Implementer and the Verifier the same brief. 3, the Implementer builds while the Verifier writes its own tests from the spec. 4, the Implementer tests its own work and hands over one exact version. 5, the Verifier tests that version and sends one verdict. 8, the Architect decides: on a valid PASS the stage is accepted and the next one starts; on a BLOCK, 6, the defect report goes back and, 7, the Implementer fixes it and hands over a new version; on a fifth BLOCK the stage is blocked and the run ends.
How one stage runs. The same loop repeats for each of the four stages.

Before the Nightshift

Illustrated portrait of Vibhor, drawn half human and half robot.

Weeks before the hackathon, Vibhor paired two AI agents, Spark and Instinct, to build hobby projects and check each other's work. Claude joined for the hackathon.
