Requiring a person's approval at specific points in an automated process, chosen so the irreversible steps are the ones a human sees.
The design question is not whether to include a human but where. Approving every step destroys the value of automation and trains people to click through without reading. Approving nothing means an agent's mistake ships.
The workable rule is to gate on reversibility: let the agent read, search, draft, and test freely, and require confirmation for anything that sends, publishes, deletes, spends, or touches production. Attention spent on those is attention that stays sharp.
