This creates main target rule called "output", in global namespace.

This creates a local rule 'output', that does nothing, and hide
the global one.

And this does nothing. What about this:

import type ;
type.register OUTPUT : output ;

import generators ;

generators.register-standard $(__name__).capture-output : EXE : OUTPUT ;

actions capture-output
{
echo "capture"
}

exe a : a.cpp ;
output a.output : a ;

I've tested it now and it seem to work.
