reliable_rubric

Return whether a message should be omitted from derived transcripts.

Nested-grader state used to scope verification-tool budgets.

Run a context-aware nested grader and retry transient transport failures.

The nested grader receives Deep Agents Code's verification middleware and runtime context without requiring those application-specific capabilities in the SDK's RubricMiddleware. A transport retry re-invokes only the grader, never the task agent, so grader tools must be read-only or idempotent.
