Internet access is required to install third party packages, so given the choice almost no one would disable it for a coding agent sandbox.
In practice, it seems to me that the sandbox is only good enough to limit file system access to a certain project, everything else (code or secret exfiltration, installing vulnerable packages, adding prompt injection attacks for others to run) is game if you’re in YOLO mode like pi here.

Maybe a finer grained approach based on capabilities would help: https://simonwillison.net/2025/Apr/11/camel/
