🧠Researchers demonstrate that MMA2A, a multimodal routing protocol for agent-to-agent networks, achieves 52% task accuracy versus 32% for text-only baselines by preserving native modalities (voice, image, text) across agent boundaries. The 20-percentage-point improvement requires both protocol-level native routing and capable downstream reasoning agents, establishing routing as a critical design variable in multi-agent systems.
