Starting with manual log inspection, they scaled their workflow using LangSmith for production monitoring, failure mode detection, and automated eval dataset collection. The EDD process involves creating evals before launching features, monitoring production for failures, adding failure examples to eval datasets, and iterating — mirroring test-driven development but for probabilistic LLM systems. LangSmith's SDK, @traceable decorator, and advanced search capabilities enabled Dosu to identify issues like slow responses on large inputs and unexpected model hallucinations at scale. ## Full article daily.dev links to this article rather than hosting it.
