Can you share technical details please? How is this implemented? Is it pure prompt-based, plugins, or do you have like script that repeatedly calls the agents? Where does the kanban live?

Not the OP, but this is how I manage my coding agent loops:

I built a drag and drop UI tool that sets up a sequence of agent steps (Claude code or codex) and have created different workflows based on the task. I'll kick them off and monitor.

Here's the tool I built for myself for this: https://github.com/smogili1/circuit
