cost control

Every eval question in the prep canon is about answer quality. This agent does not produce answers, it moves freight. You cannot score a reroute for faithfulness, and the candidate who tries has not understood what they built.

The provider bill tells you the total and nothing else. This is a forensics question, and the answer is almost never a pricey model. It is that the transcript grows every turn, so a forty step run costs six times what everyone estimated.
