NVIDIA NeMo tutorial shows agent failures turned into tests and harness fixes

According to a post on X by @Picomoorhead, an NVIDIA NeMo tutorial featuring Patrick Moorhead, Sean Lopp and Moon Chung shows NeMo Compass finding, in recorded traces, a Hermes assistant that sent messages without user confirmation. NeMo Eval Author then built tests for that failure. The post says a one-paragraph system-prompt change raised held-out passes from 4 of 6 to 6 of 6. In a Dassault Systèmes engineering example, malformed tool calls fell from 142 to zero.

Teams building AI agents can use recorded traces to turn observed failures into repeatable tests, then adjust prompts or harnesses and re-check the results. The figures come from a tutorial and a single example, and the snippet is cut off, so the full method is not visible here. Watch whether similar gains appear on other agents and tasks.

Hardware and robotics watchers may want to track whether this becomes a product, benchmark, or deployment signal.
