+## Authentication
+
+If a plugin command fails due to authentication or authorization errors (e.g., 401, 403, "not authenticated", "token expired"), run:
+
+```bash
+clime auth login
+```
+
+This will authenticate the user and store credentials for subsequent commands. Always attempt `clime auth login` before retrying the failed command.
