This skill provides a robust framework for measuring and improving the quality of AI applications by bridging the gap between raw model outputs and production-ready performance. It equips developers with implementation patterns for automated metrics like BLEU and BERTScore, advanced LLM-as-judge patterns for qualitative assessment, and statistical A/B testing logic to validate improvements. Whether you are debugging unexpected behaviors, detecting performance regressions before deployment, or comparing different model architectures, this skill provides the structured methodology needed to build confidence in LLM-powered systems.
