What

The sandbox is the restricted area Claude Code can run commands in, limiting which files and network addresses they can reach. It can now report:

  • which network allowances are configured
  • which file system permissions are configured
  • whether all Unix sockets (a way for programs on one machine to talk to each other) are allowed
  • whether a trusted setting has closed off the option of running a command outside the sandbox

The cleanup that runs after each command now also runs an extra cleanup step.

Why

This suggests stricter handling of sandbox rules, where some configurations can stop commands from falling back to running unsandboxed.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtWhether the check that blocks running outside the sandbox is actually used yet is not clear.
