AWS AgentCore Runtime adds persistent interactive shell sessions for agents

Full analysis

AWS Bedrock AgentCore Runtime now supports interactive shell sessions, giving agents stateful terminal access within their sandboxed execution environments. Unlike single-shot command execution (where each command runs in isolation), these sessions preserve environment variables, working directories, and running processes for the lifetime of the session — enabling agents to perform multi-step, stateful shell-based workflows. Each runtime session can run up to 10 concurrent shell sessions simultaneously.
