Scott Ernst

Always learning.Always building.Never bored.

I'm Scott Ernst, an AI executive who can't stop building things. In a former life I was a scientist: a PhD in physics, then a stint as a paleontologist. This is where I keep short notes, longer writing, and the things I build to see if they work.

    What 72 agents building software actually looks like

    My software factory runs on loops nested inside loops. I wanted to see what one big, successful task actually looks like from the inside, so I charted every loop.

    One orchestrator agent directed 71 subagents through about 15 active hours of work and shipped 22 pull requests of significant new functionality. That’s 72 agents on one task.

    The clock draws every loop in it: me steering the orchestrator, the orchestrator’s work episodes, each workstream’s execute, judge, fix and re-judge cycle, and each agent’s own loop of tool calls.

    That task was a big effort, and it wouldn’t have been possible without engineering the loops.

    Open the clock and find the red curls. Each one is a judge rejecting work and sending it back. Tell me what you see.

    Maestro Loop Clock

    What one big, successful software task looks like from the inside when 72 agents do the building, charted as a clock of loops nested inside loops.
