The work notes that historical responses provide useful structure, yet tasks with identical source responses can produce different outcomes for a new target agent.", "body_md": "Evaluating software agents on a full benchmark is expensive. A small task subset can preserve agent rankings while yielding inaccurate scores. Historical responses provide useful structure, but tasks with identical source responses can have different outcomes for a new target agent.
