Unclear What makes a session's interface fit or not fit is not stated.

What

When Claude Code serves a tool call, an action Claude takes such as running a command, to a remote session, it now checks whether the session's interface fits first. If it does not, the call is refused with the code unsupported_protocol before any pending approval request is replaced or any allow is used.

Why

It changes how approvals work for tools used through a remote session: some calls are now turned down early instead of going through approval.
