There's also Beans, doing MD-based ticketing in your project. It's really good. (Disclaimer: I've contributed a few of the agent rules.)

> Beans is an issue tracker for you, your team, and your coding agents. Instead of tracking tasks in a separate application, Beans stores them right alongside your code. You can use the beans CLI to interact with your tasks, but more importantly, so can your favorite coding agent! > > This gives your robot friends a juicy upgrade: now they get a complete view of your project, make suggestions for what to work on next, track their progress, create bug issues for problems they find, and more.

Much, MUCH less invasive than beads (basically just a CLI tool and a `.beans.yml` & `.beans/` in your project, and a joy to work with. CLI, TUI, labels, status, types (epic, feature, task etc.), GraphQL query interface (agents love that).

It's good.
