I believe there was a feat in either Oriental Adventures or Kingdoms of Kalamar called Skill Prodigy- I believe it had a prerequisite of Intelligence 13+. You choose one skill per point of intelligence bonus (so a character with an 18 could choose 4) and those skills are forever treated as Class Skills for you.
I think Skill Prodigy is a Kalamar feat, and I believe the AEG Rokugon book has the Versatile feat, which allows you to pick any two skills, which are then always class skills.
These two feats are both from books using the D&D logo, licensed by third parties from Wizards of the Coast. I think WotC designers have to vet all of the game content in these licensed books. (Several third party d20 publishers have come up with similar feats.)
Skill Prodigy is clearly better than Versatile, which in turn is clearly better than Skill Knowledge. On one hand, Skill Knowledge is the only feat to come straight from WotC, so it carries a certain amount of weight in that respect. But on the other hand, Skill Knowledge is presented as part of a variant, simplified skill system that places less value on the number of skill ranks spent and more value on whether a skill is class or cross-class.
Within this UA variant skill system, Skill Knowledge seems reasonably powered.
But is Skill Knowledge too weak to be used in with the standard skill system -- especially in light of the Versatile and Skill Prodigy feats?
