I’ve been experimenting with a similar pattern but wrapping it in a “factory mode” abstraction (we’re building this at CAS[1]) where you define the spec once after careful planning using a supervisor agent then you let it go and spin up parallel workers against it automatically. It handles task decomposition + orchestration so you’re not manually juggling tmux panes

Do parallel workers execute on the same spec? How do you ensure they don't clash with each other?
