What
When reading a peer's inbox message fails because the session needs to log in again, or when launching a remote/cloud subagent (a delegated Claude Code task running elsewhere) fails because of a missing access token or an authentication rejection, the response now includes a remedy describing what's wrong (for example, auth_expired or auth_overridden), built from the current login and credentials state, instead of just a plain error string.
Why
This gives a more specific reason when a login-related failure happens, making it easier to understand what needs to be fixed, such as logging in again.
