(Probably not a bug) Need console help with assigning Sleight of Hand score

I've recently discovered how much respeccing pain I can save myself through console commands. Right now though, I find myself stuck. I have adjusted the Mechanics and Athletics scores of one character just fine, and then I went to work on a second one, reducing her Arcana and Alchemy with the intent of putting those points in Sleight of Hand. The final part is what I can't seem to pull off.

FindGameData for "sleight" returns (among other things), what seems to be the relevant string: Sleight Of Hand (SkillGameData)

But, if I use Skill Companion_P_Echo Sleight Of Hand 6 it complains it doesn't accept 5 parameters. Now, the FindGameData search did not have underscores in that particular result, but I tried Skill Companion_P_Echo Sleight_Of_Hand 6 too, and then it complained it couldn't find a GameData object of type SkillGameData with that name. I also tried just Sleight with the same result.

To be super clear here, I was able to adjust Echo's Arcane and Alchemy scores just fine. She is not my Watcher, so that part should not be the problem.

Is there perhaps a nerdier version of a space I need to use, one that makes it consider Sleight Of Hand a single parameter? Or what can I do, other than give myself extra points elsewhere and just respec at an inn to put them in SoH?
