Is it a good assassin/psi build?

I would use a knife (dex), Snooping/Nimble for the first feast. Skills: hacking, lockpicking (the usual, I think I got this part figured out, nicely. For the beginning high dodge since you're mostly dealing with rathounds etc.)

Also, I didn't put much into agility, since most gear seems to pop it up.

I've never played a psi assassin with dodge/evasion, melee and stuff. But I've played a stealthy PSI, or rather, a psi user with stealth, and it's definitely one of the most OP build out there. Add some lockpicking-hacking, and use the max Will to invest in persuasion and maybe intimidation, and then mercantile and crafting using your big brain/INT, and you'll get to experience the most of the content there is to experience in one playthrough.

Wow, this build works like a blast.

Very powerful, indeed. Nearly lvl5 atm. Would recommend it, along with crip-strike and opportunist, and the punch psi ability.
