It's very easy to instruct agents to investigate and propose a plan, handing it off to a human for review and execution if that's what you want.

The example above of going through a bug backlog and double-checking closed bugs for accuracy is exactly the kind of work that is excellent for an agent. Assign that task to a normal human being and they would hate your guts. The agent won't protest as long as your token budget is there. You can confirm the results if you want.
