Designing Agents (The Floor Is the Frontier) — Ben Hylak, Raindrop
Ben Hylak from Raindrop argues that current advice on testing AI agents is designed for an older era of chatbots where user queries were predictable.
Instead, focus should be on the "floor"—the worst mistakes that destroy trust, such as when an agent recommends a competitor or deletes data—rather than on all possible problems. The key is to track two metrics for each error: when it started and how many users it affects. Hylak shares three lessons from Raindrop: classifying agent traces is not the same as error detection, automated code-based testing scales well, and agents are better at investigating anomalies than finding them on their own.
