Agents at work
What we learned running a company with AI coding agents.
2026
Every guard on our agents started as an incident
Deep diveOur AI coding agents run behind five small scripts that can refuse a shell command before it runs. None of them was designed up front. Each one is the scar from something that went wrong, and each says so in its first lines.
20.5 hours of agent time spent watching CI
By the numbersWe read two weeks of our AI coding-agent sessions by hand: 129 sessions, 496 prompts. The agents were rarely slow at the work. They were slow at finishing it: they kept stopping to ask, and 20.5 hours went on watching CI.
