Give yourself more credit. Bobby Fischer didn't wake up one morning the chess wiz that he is now, it took years of practice and failing. And we're not talking about chess either. Start prompting one agent on one task in one worktree. Spin up a second agent on a second task in a second work tree. Repeat until you hit flow state for you. It might be at three agents or thirteen. Who cares how many other people are on, get to however many is just under too many for you to manage.
