Both plugins this enables no longer exist in that marketplace, so a session in a new service would get two plugin-not-found warnings and no plugins.

• datum-claude-code-plugins dropped datum-platform and datum-gtm on 29 Oct (claude-code-plugins ab2571c, "refocus the marketplace on Datum Cloud users"). It now lists datum-cloud, datum-compute, datum-dns, datum-networking, milo-activity and milo-observe.
• Enable datum-cloud@datum-claude-code-plugins instead, or close this if the template should not pick plugins.
• The red validate-kustomize check is from a workflow the template no longer has; its log has expired, and it is not caused by this change.
