Just those.

https://github.com/oscscull/quarterdeck built my own harness. I had trouble with both claude and codex. In particular, managing multiple tasks in a kanban, syncing between my machines, making sure work is done on the right machine and can be triggered from either. Making sure I ping reviewers, meeting reminders, todos. Parking tickets til conditions are met or time elapses. Automated notifications when I have meetings. I have just kept adding features as I want them. This kind of software is so easy to make nowadays, I don't really think there's any sense in "launching" it for others, but I'm using it all the time. I highly recommend doing so (building your own personal work management software in 2026).

I guess this is also in some sense an agent orchestration tool, I don't use any of those.

Don't use.
