I don't think you need an overseer for this, you can just have the agent self-assess at each step whether it's making material progress or if it's caught in a loop, and if it's caught in a loop to pause and emit a prompt for help from a human. This would probably require a bit of tuning, and the agents need to be setup with a blocking "ask for help" function, but it's totally doable.
