Built-in evaluators

Built-in evaluators in AgentCore AgentCore Evaluations provide pre-configured evaluator for assessing your agents. These evaluators use predefined evaluator models and prompt templates that have been optimized for common evaluation scenarios.

You can use built-in evaluators with both online and on-demand evaluations. To specify a built-in evaluator, use its ID in the following format: Builtin.EvaluatorName, such as Builtin.Helpfulness.

Note

Built-in evaluator configurations, including their evaluator models and prompt templates, cannot be modified.
