Verification and repair
Artifacts as receipts
Artifacts as receipts is the practice of having an agent produce reviewable deliverables as it works, such as the plan it followed, a screenshot, the sources it opened and a note on what it could not verify, so a person can check the work in place of reading a log.
Control sits with the agent
When to use it
Any task where the output is long enough or technical enough that a person would otherwise accept it unchecked.
What it prevents
Blind acceptance, and the opposite failure of manually redoing work to confirm it.
