Plans and git worktrees. If you (or anyone else here) want more info than that, give me a way to reach out and I'm happy to help. I regularly run 40+ subagents sustained in parallel (productively) without toe-stepping or any significant rework.

Stepping on each other how? I find each agent needs to spin up N worktrees for each task, and I use hooks to prevent them working on the same substrait.

You’re not running tests in CI? The agent should only run the minimum tests necessary and then idle and wait for feedback from a CI run.

Better planning, specs, and defined agent tasks with skills and logical and technical separation.

We build modular systems with plans. One developer (not agent) with Claude Code executes their portion of the plan and everything else is normal monorepo business.

You obviously need another agent that is the only one that can run perf tests.

Turtles all the way down.

Because agents != coders
