Evidence

Auth command group (search for "Manage authentication", "Sign in to your Anthropic account")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

cli--json
Plugin eval JSON output is validated before printing, and suppressed with a stderr warning if invalid.
cli--text
Option of claude auth status. Prints the authentication status as human-readable label: value lines instead of the default JSON object, with a Not logged in line when signed out that says to run claude auth login (or, in a Cloud gateway session, to start claude and sign in with /login). The exit code is 0 when logged in and 1 otherwise in both formats.

Is this right?
