A street-lighting bureau wants two results from each cabinet photo: a flag when the panel is overheating, and a first-draft work order for the night crew. A vendor says one generative writer should detect the fault and write the order. What should the leader require?

Flagging an overheating panel is a detection job; drafting the work order is generation. Pairing a detector with a writer gives each family the job it can do. Forcing one generative model to invent both the fault and the order hides a miss and a bad draft in the same step. Leaders should keep the two jobs explicit.
