I'd very much think it's not a typo. Look at gang up, it's not a teamwork feat but it's definitely something you need teamwork to use
Hey, a player of mine got the Inquisitor's Edge guide and I had a questionI could not find the answer to. The feat Hammer and Anvil is not listed as "teamwork" but reads "Benefit: When you and an ally with this feat are flanking an opponent and you are using power attack, you gain an additional +2 bonus to damage against the flanked opponent. The bonus changes to +3 with a two handed weapon and to +1 with an offhand weapon. Commentary – While precise strike does offer a damage bonus for flanking, I found there just weren’t enough offensive options among teamwork feats to support a strength based inquisitor. I designed this feat to help fill that gap."
The commentary and way it works makes me believe it was meant as a teamwork feat. Was it a typo that this was not labeled as such?
Pretty sure, it is normally a teamwork feat if both of you need it to function. As this one doesn't require the other person to have the feat it isn't.

Yep, according to the rules, Teamwork feats are only those that require you both to have it.
This is better than a Teamwork feat since it only requires one of you (you) to have it.
a) Kobold Press book so flagged to be moved. 3rd party forums may have a better idea.
b) If it is quoted accurately then "When you and an ally with this feat" It fits the criteria for a teamwork feat, but that does not mean that it is intended to be one.
