A machine for each agent
Brockman authored E2B’s announcement of sandbox support in the OpenAI Agents SDK. The integration supplies an isolated environment in which an agent can edit files, run shell commands and keep workspace state between steps. His demonstration builds landing pages, applies patches, exposes preview URLs and runs separate variants concurrently, making generated artifacts inspectable before publication.[2]
Debugging the runtime
His sandbox workshop gives participants broken environments. They investigate runaway CPU processes, memory pressure and a full disk. The exercises make a practical distinction: an application can appear broken because its machine is exhausted, even when the code itself has not changed. Each challenge runs separately so a participant can reset a failed attempt.[1]
Ideas
The workshop then examines what happens as one workspace becomes thousands. Snapshots preserve memory, files and running processes, including processes someone forgot to stop. Mapping a user to a stable sandbox ID preserves their workspace; idle timeouts control how long unused machines remain active. Brockman also separates read-only template files from writable runtime caches. [1]

A practical workshop debugging isolated runtimes and managing persistent, per-user workspaces.
Start with the workshop if you can use a terminal. Its broken environments make CPU, disk and lifecycle problems concrete before you attempt a large agent deployment.
Instructor[1]An E2B workshop uses deliberately broken sandboxes to teach operations: finding runaway processes and disk hogs, snapshotting memory and filesystem state, lifecycle timeouts, per-user sandbox mapping, and the tradeoffs of restoring state.
