Evaluators

Agent skill
1 skill

Author or refine a Phoenix evaluator — code or LLM-as-a-judge — that scores a run's output. Trigger when the user wants to create a new evaluator, improve an existing one's logic or rubric, choose labels, or decide what to measure on a dataset or experiment. Do NOT trigger on: (1) manual prompt drafting (use playground), (2) running or comparing experiments themselves (use experiments), (3) cross-trace failure diagnosis with no evaluator in scope (use debug-trace).
