TrinityGuard: First OWASP-Grounded Safety Framework for Multi-Agent LLM Systems

arXiv 2603.15408·high signal

TrinityGuard presents a comprehensive safety evaluation and monitoring framework for LLM-based multi-agent systems (MAS), explicitly grounded in OWASP standards and designed to address risks that emerge specifically in multi-agent coordination — not just single-agent or single-LLM risks. The framework covers cross-agent privilege escalation, cascading failures, and memory contamination as distinct MAS-level threats. Released as a practitioner-deployable framework, it fills a gap no prior MAS safety system has addressed cohesively.
