That's a nice UI on that board. It's advertising the ability to allow the agent to help manage tasks, where this approach uses the tasks to drive the agent.

The way I do it is with an agents.md prompt (though the extension provides a skill). Basically, if a Kanban item is created and referenced, ai uses that to log changes, decisions, and proposed commit messages etc. If there isn't a Kanban item, it creates one and does the same.
