The GIRAFFE pipeline carries out the usual steps which are described in the page:

[http://www.eso.org/observing/dfo/quality/GIRAFFE/pipeline/recipe_science.html]

Sky fibres are extracted. But the sky subtraction needs to be carried out by the user. It is not carried out automatically because you might want to combine all sky fibres in order to get a median sky and then subtract it from the other fibre; you might want to shift a bit the skylines in order to correct to spectrograph shifts; you may want to try out to scale a bit the sky spectrum before subtraction, etc.
Thus the pipeline delivers individual sky fibres corrected for the fibre-to-fibre response.
