I have no idea on finding out how to get Mafia to tell me what the skill stuff is; however, they're up on the wiki:
Silent Slam (from Infuriating), listed as skill #0084;
Silent Squirt (from Tranquil), listed as skill #0085; and
Silent Slice (from Menacing), listed as skill #86
Hopefully this helps with getting the skill info added.
Edit: Clicking on each skill in my charpane gives me
http://127.0.0.1:60080/desc_skill.php?whichskill=84&self=true (and 85, and 86, for the other two skills), so it looks like skill numbers are be correct.
