NOD: A Multi-Agent Architecture for Reliable LLM Service Agents
Researchers propose NOD (Navigator-Operator-Director), a heterogeneous multi-agent architecture to improve reliability of LLM-based service agents in long-horizon tasks. NOD externalizes a structured Global State for explicit task tracking and introduces selective external oversight via an independent Director agent that verifies critical actions. This mitigates error propagation, tool hallucinations, and policy violations. Experiments demonstrate effectiveness.
