You could attach an additional req.args['narrow'] to formatter.req on macro execution time, that should be available later on in req object passed in filter_stream method. But I see, that using Request object is or at least is planned to be depreciated according to the wiki docs [1]. So a more sustainable way leaving the req alone would be to add a minimal, unique HTML snipped like <div id="narrow_marker"></div> and create a matching XPATH filter like xpath_match = "//div[@id='narrow_marker']" to * find it (and possibly remove it) * finally add the 'narrow' class to div#content as you already know how to do by a secondary filter expression, that should be triggered by the first one.
