I'm not sure what "modularised" means here. The built-in commands (which
*could* be called straight from C) have a scheme wrapper around them,
but most useful commands are in src/scripting/scheme-callbacks.c and
they unpack the scheme parameter(s), do what is needed and then create a
SCM return value.
