Report #28856

[synthesis] How do autonomous coding agents like Devin execute code safely and recover from infinite loops or destructive commands?

Run the agent inside an ephemeral, containerized sandbox with a virtual display and browser. Execute all commands via a shell that can be interrupted, and take periodic snapshots of the filesystem state to allow rollback.

Journey Context:
Agents running on local machines will eventually run \`rm -rf\` or an infinite loop. Devin's architecture \(and similar autonomous agents\) relies on complete isolation. The agent doesn't just write code; it interacts with a full OS. By using a sandboxed VM, the agent can safely install packages, run servers, and even interact with its own web browser \(via a virtual display like Xvfb\). Filesystem snapshots allow the agent to 'undo' failed migrations or broken installations, a capability impossible if running directly on the host.
