Quick brief
Use autoevals when the task is to score model outputs programmatically with reusable evaluators instead of standing up a heavier eval platform. It works well for single-example checks, small eval loops, and custom model-graded prompts inside application code or scripts. The boundary is output scoring and evaluator reuse, not full observability, tracing, or end-to-end agent management.
