Temporal Workflows can now integrate with various sandbox providers (e.g., Modal, E2B, Daytona) to securely execute untrusted, agent-generated code. This "Sandbox Orchestration Harness" provides reference materials, patterns, and best practices for provisioning, managing the lifecycle, persisting state, and cleaning up these temporary compute environments, ensuring they align with the durable execution of AI agents.

Temporal Sandbox Orchestration Harness: The missing layer for running agents

5/7/2026

Introduces the concept of a "Sandbox Orchestration Harness" as a missing layer for agent infrastructure. Provides reference materials and community code samples for integrating sandbox providers (like Modal, E2B, Daytona) with Temporal Workflows. Details patterns for on-demand provisioning, driving execution from agent intent, persisting state across long runs, recovering from sandbox failures, and cleaning up temporary environments. Includes a Go example for provisioning a Modal sandbox with idle timeout.
