Amazon Bedrock AgentCore introduced a managed harness (preview) that enables defining and running agents with specified models, prompts, and tools without writing orchestration code. It supports model-agnostic execution, session persistence, and resource isolation per session using microVMs.
Additional tools include a CLI for infrastructure-as-code deployment and pre-built skills to assist coding assistants. These features improve experimentation speed, lifecycle management, and quality evaluation of agents. The harness and CLI are available across multiple AWS regions, facilitating rapid agent prototyping and operationalization.
