X_EVAL_MISSING
Means
a prompt has no eval
Typical cause
a definePrompt with no defineEval naming it
Fix
defineEval({ name, prompt, cases, scorers, tolerance, baseline }) beside the prompt — for a prompt an agent() runs, defineEval({ name, agent, cases, tools, scorers, tolerance, baseline }) — then ULTIMATE_EVAL_RECORD=1 x test eval
