AgentCore Runtime Gets Interactive Shells and Persistent File Systems

Full analysis

AWS AgentCore Runtime now supports interactive shell sessions, giving agents persistent terminal access — including environment variables, working directories, and running processes — that survive across commands for the lifetime of a session (up to 10 concurrent shells). In the same release cycle, agents can mount Amazon S3 Files and Amazon EFS (Elastic File System) access points directly into runtimes, enabling agents to share datasets and prompt templates across sessions and collaborate on the same data across multiple agents. Both capabilities are available across all 15 AWS Regions where AgentCore Runtime is supported.
