Verifiable Semantics for Agent-to-Agent Communication
arXiv:2602.16424v1 Announce Type: new Abstract: Multiagent AI systems require consistent communication, but we lack methods to verify that agents share the same understanding of the terms used. Natural language is interpretable but vulnerable to semantic drift, while learned protocols are efficient but opaque. We propose a certification protocol based on the stimulus-meaning model, where agents are tested on shared observable events and terms are certified if empirical disagreement falls below a statistical threshold. In this protocol, agents restricting their reasoning to certified terms ("core-guarded reasoning") achieve provably bounded disagreement. We also outline mechanisms for detecting drift (recertification) and recovering shared vocabulary (renegotiation). In simulations with varying degrees of semantic divergence, core-guarding reduces disagreement by 72-96%. In a validation with fine-tuned language models, disagreement is reduced by 51%. Our framework provides a first step

Executive Summary
This article proposes a novel certification protocol for multiagent AI systems to ensure consistent communication. Agents are tested on shared observable events, and terms are certified if empirical disagreement falls below a statistical threshold. The protocol, dubbed 'core-guarded reasoning,' achieves provably bounded disagreement. The authors also outline mechanisms for detecting semantic drift and recovering shared vocabulary. Simulations and validation with fine-tuned language models demonstrate the effectiveness of the protocol in reducing disagreement. The framework provides a crucial step towards verifiable agent-to-agent communication, with potential applications in areas like autonomous systems, negotiation, and decision-making. However, the protocol's scalability and applicability to real-world scenarios are areas that require further investigation.
