[3.5e] Crafting Constructs

[Irreverent Fool]

Constructs are usually unintelligent. Some few have intelligence scores and have specific skills built into their monster entries. It's safe to assume that an intelligent construct has the skills listed in its entry as class skills, but what about constructs that later gain an intelligence score? Or ones that are augmented by "Rudimentary Intelligence" (DM #327) and have an intelligence score from the get-go? There doesn't seem to be a 'class skills for constructs' listing.

I ask partially because Snizor's Mechonomicon (http://forums.gleemax.com/showthread.php?t=977748) mentions that an advanced Homunculus (http://www.d20srd.org/srd/monsters/homunculus.htm) could make a good "UMD-turret", but somehow assumes that it gets UMD as a class skill (and that you can somehow get a masterwork tool for UMD which I find preposterous)

[Lord Lorac Silvanos]

The problem is that the skills listed in the creature entry are class skills, so if the creature normally has no intelligence you will not find any.

There is no option for choosing other skills as class skills for the MM version of the Homunculus. (Perhaps Eberron can provide alternatives, but I am AFB at the moment, so I cannot check.)
