When Numbers Start Talking: Implicit Numerical Coordination Among LLM-Based Agents

ArXi:2601.03846v2 Announce Type: replace-cross LLMs-based agents increasingly operate in multi-agent environments where strategic interaction and coordination are required. While existing work has largely focused on individual agents or on interacting agents sharing explicit communication, less is known about how interacting agents coordinate implicitly. In particular, agents may engage in covert communication, relying on indirect or non-linguistic signals embedded in their actions rather than on explicit messages.
