Persist session state with filesystem configuration and execute shell commands

This article announces two new capabilities for Amazon Bedrock AgentCore Runtime: managed session storage for persistent filesystem state and execute command for running shell commands directly in agent sessions.

• Managed session storage persists agent filesystem state across stop/resume cycles
• Configure persistent storage by adding sessionStorage to filesystemConfiguration at mount path /mnt
• Session data retained for 14 days of idle time before cleanup
• Execute command runs deterministic operations like npm test or git push directly in agent environment
• Commands execute in same container and filesystem as agent with streaming output
• Each command spawns new bash process; no persistent shell session between commands
• Shared filesystem enables workflows combining agent reasoning with deterministic operations
• Use cases include test automation, git workflows, environment bootstrapping, and validation gates

Together, managed session storage and execute command enable multi-day development workflows where agents can persist work across sessions and run deterministic operations without LLM routing.
