Don't Ship Agent Skills Naked: Eval First

AI Engineer · youtube · 2026-07-14

Philipp Schmid from Google DeepMind addresses a frequently overlooked issue in agent development: skills shouldn't be shipped after just a couple of manual tests—they require rigorous evaluation.

He points out that while agents may boast numerous skills, they are rarely tested. From an engineering standpoint, developers should establish lightweight eval harnesses for skills—just like deploying code—to proactively catch trigger failures, behavioral anomalies, and regressions.

The talk also covers skill definitions, how to write skills that trigger reliably, and a comprehensive reliability pipeline spanning construction, evaluation, and pre-deployment validation.
