EIO-Agents: The Missing Semantic Layer for AI Agent Evaluation

We introduce EIO-Agents, an open specification for interoperable AI agent evaluation built on two layers.

Key points

  • AI agents are entering production in increasingly consequential environments without a shared semantic standard for what their evaluations actually mean.
  • Scores, traces, judge outputs, and multi juror findings are increasingly used to justify readiness and release decisions, yet they often do not specify what evidence supports a claim, what that evidence can establish, or how the claim leads to a decision.
  • The Evaluation Intelligence Ontology (EIO) provides the semantic layer through typed evidence, versioned behavioral predicates, evidence contracts, claims, witness rules, proof status, recurrence, and computable derivations for metrics, findings, controls, and PASS, REVIEW, or BLOCK decisions.
  • As AI agents assume greater operational responsibility, evaluation must become more than a collection of scores and verdicts; it must become an accountable artifact whose meaning, evidence, limitations, and decisions can be independently checked.
