What
Claude Code can run in a cloud container with your own computer attached, so commands can run on either. New instructions in Claude's system prompt (the standing guidance Claude reads before your messages) cover:
- Machines listed as "Not reachable right now": carry on with the rest of the task, do not keep checking, and retry only once and only if you ask.
- Things that exist only on your computer, such as Xcode, Android, Windows or GPU tools, the Docker daemon,
/Userspaths and hosts behind a VPN: send that work straight to your machine. - No machine attached: commands run in the container, and Claude should ask for a machine to be attached when it needs one.
Why
This shapes where Claude decides to run commands in a cloud session, and what it does when your computer is not available.
