It works quite well, and then you can review the cards (as files) and then ask another AI agent running as whatever role is suitable for that card, to pick up the card by name and do the work.
But there is no kanban board, it's just .md files in a folder.
I am continuing to test this, as transfer of context between AI sessions is an interesting challenge, and leveraging md files as if they are kanban / agile style cards, is interesting.
