Where can you find Swords Secret online?

I was reading the Lore Warden (PRG:AG) archetype (careful, there is another Lore Warden archetype for fighter) and one of its features is the swords secret, but I cant find any of them online.

Swords Secret

A lore warden learns specialized techniques that help her to quickly analyze and defeat her foes. At 3rd level, a lore warden gains one swords secret, and she gains an additional swords secret for every 4 fighter levels gained after 3rd. Except where noted, a lore warden cannot select the same swords secret more than once.

I wasnt able to find this listed on d20pfsrd, nythys, or with a google search.
