Hey there, I'm another member of the superset team! I think it's definitely something you have to get used to, and it is somewhat task dependent.

For bug fixes and quick changes I can definitely get to 5-7 in parallel, but for real work I can only do 2-3 agents in parallel.

Human review still remains the /eventual/ bottleneck, but I find even when I'm in the "review phase" of a PR, I have enough downtime to get another agent the context it needs between agent turns.

We're looking into ways to reduce the amount of human interaction next, I think there's a lot of cool ideas in that space but the goal is over time tools improve to require less and less human intervention.
