Unclear It is not clear which remote clients can use this tool or whether something switches it on.
What
Claude Code has a new tool, ListDirectoryForRemote, that a remote client can use to list the contents of a folder. It checks the path and the session's permission rules first. It gives back a capped list of entries, or a refusal with a reason:
read_rule, when a permission rule blocks reading the folder.workspace_moved, when the project folder has moved.unexpected_error, for anything else.
Why
A remote client can browse folders on your machine while still being bound by the same permission rules as the session.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
