What
When Artifacts (Claude's rendered code/content outputs) need you to be signed in to claude.ai and you're not, Claude Code now shows a more precise error depending on your situation:
A remote-session message explaining that the host machine (the one actually running the session) needs to be signed in
A message for sessions where credentials are injected by the host environment, noting this can't be changed locally

Previously the login error was likely one generic message regardless of setup. Now, if you're in a remote session or one where your login comes from the environment rather than a local /login, the error tells you where the actual problem is instead of pointing you at a command that won't fix it.
