The US NEC requires a disconnecting means for each separate structure.

"225.31 Disconnecting Means.
Means shall be provided for disconnecting all ungrounded conductors that
supply or pass through the building or structure.
225.32 Location.
The disconnecting means shall be installed either inside or outside of
the building or structure served or where the conductors pass through
the building or structure. The disconnecting means shall be at a readily
accessible location nearest the point of entrance of the conductors. For
the purposes of this section, the requirements in 230.6 shall be
permitted to be utilized."

So as long as your panel is located "at a readily accessible location
nearest the point of entrance of the conductors" all you have to do is
install a double pole breaker with a breaker tie down kit and feed your
supply into the breakers terminals. That breaker is then the service
disconnecting means for the shed. The phrase "nearest the point of
entrance of the conductors" is generally held to mean not more than five
linear or ten wire feet from were the conductors enter the structure.

Since, IIRC, you are in Washington State you would be under the Uniform
Building Code (UBC). The UBC has no rules about whether the disconnect
is inside or outside of the structure. The Southern Building Code
required and exterior disconnecting means at one time.

OK so just add a double pole 30A breaker as a main breaker in the panel.

As long as there are no more than 6 breakers in the shed he is OK
without a "main" out there.

That's true as long as all of the breakers are clearly labeled to
indicate they are service disconnecting means.
