Related is Beads [0] which is an external memory and task based issue tracker. Also designed to allow agents to collaborate. I have not actually used Beads but since we are share basics in this space it's a cool one to know if you are looking at ways for agents to collaborate on more complex problems.
I used beads in its early days and it was good.
Then Steve Yegge went off the multi-agent deep end and it became a mess of feature creep. Month old versions of beads databases needed massive updates and the system became more and more complex.
Now I just use Github issues instead.
I vastly prefer Beans, https://github.com/hmans/beans, for much simpler code and use.
