arXiv:2607.04419v1 Announce Type: new Abstract: Most agent evaluations collapse a multi-step trace into a final answer, a success flag, or a trajectory-level score. These aggregates obscure the diagnostic question developers need most: which action changed the state in a useful direction? We introduce Agent Step Value (ASV), a state-transition measurement framework that scores each observed action by the change it induces in a state-grounded evaluator's distribution over fixed candidate outcomes. ASV renders redacted before/after state projections, uses a stateless LLM evaluator to assign cand
The rapid advancement of large language models and agentic systems necessitates more granular evaluation methods to improve development and deployment efficiency.
This development allows for a more precise understanding of agent behavior, enabling faster iterative improvement and more robust autonomous systems which are critical for broader AI adoption.
AI agent evaluation shifts from aggregate metrics to a state-transition measurement, highlighting the value contribution of individual actions and enabling more effective debugging and optimization.
