What
Claude Code's instructions to the model already say that tool results show where each command ran. They now add a rule: if a machine's notes say its commands run in a VM (a virtual machine, a separate computer simulated inside your own), Claude should tell you the command ran in that VM on your computer.
Why
It changes how Claude describes where a command ran, so you are not left thinking a command touched your own system directly when it ran inside a VM.
