Agent evals score runs against desired behaviors, but exact-output tests often fail because agent outputs and paths vary. The guide recommends starting with 10 to 20 examples drawn from traces, combining code evaluators with LLM judges and human review, and using offline and online evals at different stages.

Browsers fetch lazy-loaded media at different distances, with Chrome adjusting its margin based on connection speed, Firefox using a fixed 600-pixel threshold, and Safari applying a viewport-based threshold to images.
