Description of Changes

This PR adds some of the AgentCore features.

Design Considerations

  • AgentCore is in preview and GenU implementation is experimental and subject to change. There may be breaking changes in the future.

  • The implementation is based on CDK Custom Resource while CloudFormation and CDK is supported for AgentCore. Breaking changes may occur when migrating.

Feature Implemented

  • AgentCore Runtime:

    • Default Generic Agent: Implemented with default generic Strands AgentCore Runtime execution environment.

    • External Agent: Capability to register external AgentCore Runtime. You may bring your own agents / sample agents from the repository. Input and Output format is expected to be compatible with Strands SDK. (See type definition: packages/types/src/agent-core.d.ts)

    • Current limitation: Only text input is supported. File support is planned.

  • AgentCore Identity: IAM Authentication (Cognito ID Pool)

  • AgentCore Observability: Implemented. (CloudWatch Transactional Search should be enabled separately. See doc)

  • AgentCore Tools Code Interpreter: Implemented with Strands tools.

Future Work

  • AgentCore Gateway: Not implemented. Gateway may be implemented in future.

  • AgentCore Memory: Not implemented. Traditional DynamoDB based persistent memory is used. Long Term memory may be implemented in future.

  • AgentCore Tools: Partially implemented. Code Interpreter is implemented. Planned to integrate with Browser Use.

Checklist

  • Modified relevant documentation
  • Verified operation in local environment
  • Executed npm run cdk:test and if there are snapshot differences, execute npm run cdk:test:update-snapshot to update snapshots
