On Paizo's website, as well as D20PFSRD, it lists one of the skills for the Arcane Trickster as Disable Device (INT).
Disable Device is normally a dexterity based skill. Is this a typo on both websites, or is there something I'm missing?
It appears to be a copy-paste from the D&D 3.5e arcane trickster, which also had Disable Device as a class skill, except that Disable Device was an Intelligence-based skill in 3.5e (and Open Lock was a separate, Dexterity-based skill, that Pathfinder merged with Disable Device).
Ultimately, the little parenthetical note in class skill lists is there purely to be a reminder, so this error has no actual effect on the game rules; the primary source on this subject is the Disable Device skill description itself, and that says Dexterity.
