What we learn building Maxxwell — supervising many coding agents at once, and what actually breaks when you do.
Past two or three coding agents, you stop being limited by model quality and start being limited by your own attention. You have more terminals than you can.
Most teams now have more AI output than attention. The real problem is how to run and coordinate multiple AI coding agents without breaking prod or wasting.
Past one or two coding agents, the problem stops being model quality and becomes orchestration. You’re suddenly a traffic controller for parallel work that can.
Developers are now the bottleneck, not the models. Once you’re running five or ten coding agents, the hard part is keeping them aimed, not getting more code.
Most people who run Claude Code or Codex seriously hit the same wall: the agents scale, your attention doesn’t.
Why the first thing that breaks when you run several coding agents on one repo is the working directory, and what git worktrees fix about it.
Past one or two coding agents, the problem stops being code generation and starts being you babysitting terminals.
Most teams already run AI coding tools. Stack Overflow’s 2025 survey says 51% of professional developers use AI daily, and JetBrains reports 85% regularly use.
