We aren't some European country that has to put every clerk and dogcatcher in our constitution, and we would not want it that way.
Congress has the authority to add departments to the Executive Branch primarily through its Article I powers, especially the Necessary and Proper Clause, allowing it to create federal offices, define their functions, and fund them via legislation, although the President appoints heads with Senate approval under the Appointments Clause. This power stems from Congress's broad constitutional role in legislating, organizing government, and ensuring laws are executed, making it the primary creator of the federal bureaucracy.
