Hey there!
An Anti-Federalist would limit the Federal government strictly to "managing of foreign affairs".
This is because it was one of the only powers that the Federal government had under the Articles of Confederation, which the Anti-Federalists were not interested in changing. So, they limited the federal government to only managing foreign affairs.
Hope this helps!
