Linguistic Firewall: Geometry as Defense in Multi-Agent Systems Routing

arXiv:2606.30555v1 Announce Type: new Abstract: The rapid integration of Large Language Models (LLMs) has driven the evolution of Multi-Agent Systems (MAS), where specialized agents collaborate to execute complex workflows. Effective orchestration in these environments requires robust routing mechanisms to efficiently allocate tasks to the most suitable agent. However, existing routers fundamentally rely on unverified proxies, ranging from textual self-descriptions to static surrogate representations, to gauge an agent's competence. This reliance on non-empirical data creates a critical gap be

Why this matters
Why now

The rapid deployment of Large Language Models has necessitated more robust and verifiable routing mechanisms in multi-agent systems, moving beyond unverified proxies.

Why it’s important

This development addresses a critical vulnerability in the efficiency and reliability of AI agent coordination, which is central to the future scalability and trust in autonomous systems.

What changes

The proposed 'Linguistic Firewall' introduces a geometric defense for multi-agent system routing, fundamentally altering how agent competence is assessed and tasks are allocated.
