Builder

The unique identifier of the evaluator to retrieve. Can be a built-in evaluator ID (e.g., Builtin.Helpfulness) or a custom evaluator ID.

Controls which data is returned in the response. ALL_DATA (default) returns the full evaluator including decrypted instructions and rating scale. For evaluators encrypted with a customer managed KMS key, this requires kms:Decrypt permission on the key. METADATA_ONLY returns evaluator metadata and model configuration without instructions or rating scale, and does not require any KMS permissions.
