Evaluating AI Agents via Step-Level and End-to-End Scoring
September 23, 2026
Robust agent evaluation requires combining step-level scoring to pinpoint specific failures with end-to-end environment state verification. Developers should also track reporting consistency and total cost alongside standard success rates.
HOW THIS AFFECTS YOU
