Personally, I have been using beads for a few days on a couple of projects. I also like https://github.com/Dicklesworthstone/beads_viewer which is a nice tui for beads (with some additional workflow i haven't tried). I have found its been useful for longer, multi-session implementations. Its easier to get back into the work. I wouldn't go so far as to it couldn't do the work without it, but so far it seems smoother. These things are hard to measure. I think the it's really not that different than how an engineering team would use jira but more hierarchical, which helps preserve context, and with prebuilt instructions for how the agent should use it.
