Build Your Eval Harness: A Practical Guide to Testing Every AI App Change
ArtificialOther · x · 2026-10-29
Tony Cueva published part 2 of his evals-and-tracing guide, 'Build Your Eval Harness,' aimed at engineers, QAs, and PMs testing every change to their AI app. Core thesis: teams constantly ship changes—new models, tools, prompt edits—each fixing one bug while quietly breaking another. The agent harness makes your model useful; the eval harness tells you what broke before a customer does. Retweeters call it the best eval guide they've seen in a while, especially for PMs.
