# Replay one eval and grade it against the recorded answer

Runs the real generation path, then grades the reply against preferred\_output on substance rather than wording. `passed` is null — never false — when grading could not run, so an unavailable judge is not mistaken for a failing agent.

### Path parameters

<ParamField path="id" type="string (uuid)" required>
  The eval id.
</ParamField>

### Response

Returns `object`.
