That's the problem in a nutshell.

In common programming terminology, the word "type" refers to a single variable or symbol.  A strongly-typed language will flag a compilation error if incompatible types are used, for example 'i=x' where 'i' is declared to be an integer type and 'x' is declared floating-point.  Extending this concept of "type" to a complex structure like a UNOIDL interface, which may include many different atomic types, makes sense.  But I can't see how it can possibly refer to a "service".

An IDL interface and an IDL service are different things entirely, conventionally distinguished by prefixing 'X' to interface names.

And in the case of the uno-skeletonmaker 'calc-add-in command', specifying a service works but specifying an interface fails.  So I argue that the documentation and HELP text are plainly wrong and should be corrected.  After all, skeletonmaker is only at version 0.4!

Perhaps it would be worthwhile checking that this inconsistency doesn't hide some deeper problem.  It feels to me like the result of a misunderstanding or a sudden change of design which may have further ramifications.
