CodeBasedOptions

class aws_cdk.aws_bedrockagentcore.CodeBasedOptions(*, lambda_function, timeout=None)

Bases: object

Options for configuring a code-based custom evaluator using a Lambda function.

Uses a Lambda function to implement custom evaluation logic.

Parameters:

lambda_function (IFunction) – The Lambda function used for evaluation. The function will be granted invoke permissions for the bedrock-agentcore.amazonaws.com service principal, scoped to this specific evaluator resource.
timeout (Optional[Duration]) – The timeout for the Lambda function invocation during evaluation. When not specified, the AgentCore evaluation service uses its default timeout for Lambda-based evaluators. Default: - The AgentCore evaluation service’s default Lambda timeout is used

ExampleMetadata:

fixture=default infused

Example:

# eval_function: lambda.IFunction


code_evaluator = agentcore.Evaluator(self, "CodeEvaluator",
    evaluator_name="custom_code_evaluator",
    level=agentcore.EvaluationLevel.TOOL_CALL,
    description="Evaluates tool call accuracy using custom logic",
    evaluator_config=agentcore.EvaluatorConfig.code_based(
        lambda_function=eval_function,
        timeout=cdk.Duration.seconds(30)
    )
)
