I like your 2-plane mesh setup with multiple top-level agents and 'you' on the manager plane mesh that are able to communicate via a daemon mediated communication.
The daemon is the Telegram bridge, the tmux router, the CI status deliverer, and the cleanup coordinator all in one process. It allows for cross star topology communication unlike MoMa that basically just corresponds to a single manager and is similar to your plan-review-leader agent living in the manager plane if that one was isolated.
My previous concern was that maybe you would face a timeout in case user input was needed during a pipeline run, and in a case where the user was too slow to provide an answer through telegram (I imagine during the night), but maybe even github pipelines can be set to wait unlimited.
I really like the setup, and exactly I also faced the no nested agent spawning limit by Anthropic for Claude Code built-in agent tooling, that dictates the star topology in the first place.
I use the git worktree as well for every MoMa agent and they all live in Linux screen session. Maybe I should consider going to tmux myself instead of screen as I understand all your agents in top-level manager plane also are just tmux sessions.
