Osiris's first skill is damage + dizzy debuff to single enemy. Her second skill is granting invulnerability, or 100% miss, on self.
Neftis's second skill is a new effect implemented with her arrival. The "sneak attack" is a mis-translation on Google's part. The actual effect is more like "bonus amplication". In other words, if you use her in battle and cast her second skill, you will receive a buff that amplifies your damage ONLY WHEN faced against enemies from advantageous elements, for 3 turns. I'm not sure if the bonus is equal in facing against light vs 4 other elements though.

As a side note: when the first Miracle SSR gacha ticket was out, the top choice for all DMM players was Osiris.
