In a unitary frame the metric matrix is $I$. If $A$ is the <connection one-form>, <metric compatibility> gives $0=dI=A^*+A$, so
$$
\boxed{A^*=-A;}
$$
the matrix is <Skew-Hermitian>. In a <holomorphic local frame>, every frame vector is annihilated by $\bar\partial_E$, and compatibility with the holomorphic structure gives
$$
\boxed{A^{0,1}=0.}
