SummaryLangChain describes treating agent improvement as a data mining problem: mining execution traces to find failures, fine-tuning smaller open models as judges to process trace data at scale, and using evals to hill-climb agent performance through continual learning loops.
Why it mattersFrames agent improvement as an iterative data pipeline rather than prompt tweaking, with concrete hooks for teams already running agents in production.
