Beyond pass/fail: devs debate how to evaluate agent decisions with real costs

A developer building an agent that makes real decisions (pay a supplier / verify / escalate) asked Reddit: most agent eval tooling (DeepEval, faithfulness scoring) only checks output quality with pass/fail, which is far too blunt.

He asks whether practitioners attach cost weights to failure types, calibrate agent confidence, or mostly still ship if the demo looks right.
