I havent quite dealt with "teams of agents" yet outside of Claude Code itself spawning subagents, but I have some ideas as to how to achieve it in a meaningful way without giving a developer 10 claude code licenses, I think the real approach that makes more sense to me is to still have humans in the loop, but have their respective agents sync together and divide work towards one goal, but being able to determine which tasks are left to be worked one and tested. I do think for the foreseeable future you will need human validation for AI.
