Siftei Chachamim (שפתי חכמים) is a super-commentary on Rashi's commentary on the Torah, written by the 17th-Century CE Polish scholar Shabbethai Bass. It tends to be included in Mikraot Gedolot editions of the Torah.
Ikar Siftei Chachamim (עיקר שפתי חכמים) is a more concise super-commentary on Rashi that tends to appear in smaller, often one-volume, synagogue and school editions of the Torah. In general, it reads like an abridged version of Siftei Chachamim, but it sometimes includes non-trivial ideas that don't appear in the larger work (e.g. the one discussed here).
Even without the additional ideas, the editorial decisions involved in abridgement would have required a careful editor. The additional ideas make the identity of the editor/author even more interesting. However, I haven't yet found an attribution. Who wrote this commentary?
