This article discusses the importance of writing regression tests for LLM extraction prompts before making modifications. It highlights how seemingly small changes to a prompt, like adding a clarifying sentence, can inadvertently degrade the accuracy of other extracted fields, leading to issues like billing complaints. The author proposes creating a 'golden set' of documents, carefully curated and labeled by hand, to serve as a fixed benchmark for testing prompt accuracy. This rigorous testing process aims to catch regressions at the per-field level, ensuring overall system reliability. AI
