Report #20822

[synthesis] Agent running commands directly on the host machine without isolation or state rollback

Execute all agent actions inside a sandboxed environment \(like a Docker container or VM\) with a persistent filesystem and browser, allowing for safe execution and state snapshots.

Journey Context:
If an agent runs a destructive shell command on the host, it's catastrophic. Devin's architecture \(a remote VM\) isolates the blast radius. Furthermore, a persistent filesystem allows the agent to write files, install dependencies, and run a dev server, then interact with its own running app via a headless browser. This 'act-observe' loop in a sandbox is critical for autonomous software engineering.
