Codex Cloud not able to create automatic PRs

I would use that technique when you give each subagent an own Sprint. I rather let them work together on one Sprint and I let them work in own worktrees (you need to tell codex to delete unused worktrees or else you will end up with hundrets of them) with smaller tasks. The orchestrator automatically gives them small tasks that fit.. e.g. one works on translation files, one creates images, one builds templates, etc..
