    "body_text": "The Mental-Models framework asks multi-agent systems to represent what other agents know, intend and may do, instead of relying only on the latest message. That explicit state gives coordination a place to record disagreement, uncertainty and changed assumptions. The paper positions mental models as an organizing layer for agent teams, where the quality of collaboration depends on whether those models are updated when behavior contradicts expectations. This is a research proposal and evaluation framework, not evidence that software agents possess human social understanding. Its useful test is operational: can an agent explain which teammate assumption drove a plan and revise it after contrary evidence?",
