IssueBench is an internal benchmark created by LangSmith to assess the performance of Engine, a continual‑learning agent that scans other agents’ traces to identify, cluster, and fix issues. In the blog, Nick Bray explains why the benchmark was needed, outlines the types of issues it evaluates, and describes the design and implementation of IssueBench. The result is a systematic method for measuring Engine’s effectiveness in real‑time agent maintenance.
