A unique, case-sensitive identifier to ensure that the API request completes no more than one time. If you don't specify this field, a value is randomly generated for you. If this token matches a previous request, the service ignores the request, but doesn't return an error. For more information, see Ensuring idempotency.

The updated description of the evaluator.

The updated configuration for the evaluator. Specify either LLM-as-a-Judge settings with instructions, rating scale, and model configuration, or code-based settings with a customer-managed Lambda function.

The unique identifier of the evaluator to update.

The Amazon Resource Name (ARN) of a customer managed KMS key to use for encrypting sensitive evaluator data. Specify a new key ARN to rotate the encryption key, or specify a key ARN to add encryption to an evaluator that was previously created without one. When you rotate to a new key, the service decrypts the existing data with the old key and re-encrypts it with the new key. Only symmetric encryption KMS keys are supported. For more information, see Encryption at rest for AgentCore Evaluations.

The updated evaluation level (TOOL_CALL, TRACE, or SESSION) that determines the scope of evaluation.
