What
Claude Code can run tools inside a sandbox, a restricted environment that limits what commands can access. Previously, if the setting controlling whether sandboxing is enabled changed while a session was running, the sandbox would not pick up that change. Now Claude Code watches for that setting to flip and automatically re-initializes the sandbox when it does. If the re-initialization fails, an error is logged.
Why
This keeps the sandbox in sync with the current setting instead of continuing to run under a stale configuration for the rest of the session.
