Tracing Agent Harness Behavior with NVIDIA NeMo Relay

NVIDIA Developer Blog · Sep 30, 2026 · Engineering Insights

NVIDIA NeMo Relay traces agent harness behavior to expose hidden inefficiencies even when tasks succeed.

“An agent can finish a task and still take an inefficient path.”

NVIDIA's NeMo Relay provides tracing for agent harness execution, surfacing redundant steps like duplicate searches and repeated file reads that are invisible when the final answer is correct. This matters because task success metrics alone mask latency and token overhead from suboptimal execution paths. The tooling addresses a real gap in agent evaluation as production agentic workloads scale.
