How does one typically consider incentives and buyers agent’s commission?

My case: I’m looking to buy a home, in a mild buyers market. A New build home is selling for $290k while the seller (builder) is also offering $15k in “anyway money” as an incentive.

My questions:

1. What about my RE agent’s fee (as a buyer’s agent, which is 3% of the purchase price or $7800), do I ask for the seller to cover it as well (considering that there is already a $15k incentive)?

2. Is the buying agents fee a totally separate line which is expected to be covered to a large extent by the seller?

Thanks!!!
