Unclear It is not clear whether or where these warnings are shown to you.
What
The sandbox is the walled-off space Claude Code can run commands in to limit what they can touch. Claude Code's sandbox code now has functions for producing warnings:
- that the sandbox needs setting up again
- that a restart is needed, including for local connections
- about profile files being readable
It also has a check for whether the sandbox was set up by administrators.
Why
These point toward the sandbox telling you when it needs a restart or when profiles can be read.
