Evaluating AI agents has evolved beyond simply checking the final outcome. New frameworks, as of July 2026, allow for step-level analysis, distinguishing between different types of failures. These tools can now assess specific aspects like correct tool selection, argument accuracy, and path quality, rather than just overall task completion. The key distinction among these frameworks lies in whether they rely on LLM judges for these granular evaluations or employ deterministic, code-based checks. AI
