+            Automated synchronization with the latest published `command-code` CLI package.
+
+            This updates only machine-readable compatibility metadata:
+            - CLI version used in the `x-command-code-version` header
+            - image-input capabilities
+            - supported reasoning efforts
+            - documented catalog snapshot version
+
+            Pricing remains review-only because CLI documentation does not represent every pricing tier and temporary promotion used by the provider.
