Organize LLM prompt regression tests by failure mode, not features

This article proposes a new method for structuring prompt regression suites by organizing them around failure modes rather than application features. This approach aims to solve issues of duplication and lack of information in feature-based suites. By grouping tests by failure type, such as format errors, instruction drops, or fabrications, developers can more efficiently identify and address prompt-related issues. AI

IMPACT This approach could improve the maintainability and efficiency of LLM development by providing a more structured way to test and debug prompts.

    Structuring a Prompt Regression Suite by Failure Mode

    <p>Most prompt suites are laid out the way the application is laid out: one directory per feature, one file per prompt. That mirrors the code and it is exactly wrong, because a prompt change does not respect feature boundaries and a failure organised by feature tells you nothing …
