What
In a cloud session, meaning a Claude Code session running on a remote machine instead of your own computer, Claude Code now looks through your prompt for full file paths. These are paths starting with ~/, with /, or with a drive letter such as C:.
If a path is not inside one of the folders synced to the cloud session, Claude Code shows a notice that begins "The cloud session can't open ... on your computer:", lists the paths, and says "Paste what you need from it into a new message."
Why
A cloud session cannot see files that only exist on your computer. The notice tells you straight away, so you can paste the contents in instead of waiting for Claude to fail to find the file.
