What
The sandbox is a protective boundary that runs some work inside a separate virtual machine. When data is copied between that virtual machine and Claude Code, Claude Code now stops with an error if the data is nested deeper than a set number of levels. The error says that nesting deeper than that many levels is not supported across the VM boundary.
Why
Tool or script data that is nested very deeply will now fail with a clear message.
