EB-MAS proposed to constrain multi-agent belief updates with a cognitive firewall
Start here
An arXiv paper proposes the EB-MAS framework, which externalizes the belief states of agents in LLM-driven multi-agent systems into structured carriers, adding an auditable safety layer for belief updates: a belief operator proposes candidate updates, and a cognitive firewall limits or rejects updates that are weakly evidenced and driven mainly by vulnerability cues. The authors also discuss group belief risks such as manufactured consensus, collusion, and misinformation cascades, and argue for tracking, calibrating, and constraining belief revision at runtime.

- arXivAuditable Belief Updates: The Missing Safety Layer in LLM-Driven Multi-Agent Systems
The paper proposes the EB-MAS framework, which externalizes agent belief states into structured carriers, adding an auditable belief-update safety layer to LLM-driven multi-agent systems. The framework uses belief operators to propose candidate updates, and a Cognitive Firewall to restrict or reject updates that are weakly evidenced and driven mainly by vulnerability cues. The authors also discuss group belief risks such as manufactured consensus, collusion, and misinformation cascades, arguing that scalable agent safety requires explicit interfaces for tracking, calibrating, and constraining belief revision at runtime.
