What
A sandbox is a restricted environment that limits what commands can reach. On macOS, Claude Code runs a check to decide whether a sandboxed feature can be used. That check now returns more detailed results:
person: returned when sandboxing or a network proxy is already on and a newer capability check passes. Before, this case always returnedperson_sandbox.person_read_rules: returned when read rules conflict.locked: returned on the normal success path.
The check can also report that the feature is unavailable.
Why
A sandboxed feature on macOS may now work inside a session that is already sandboxed, where before it was always turned away.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is not clear which feature relies on this check, or what the new capability check behind the `person` mode tests.
