Let $E$ be a Dirac bundle with metric $h^E$, and $\nabla^E$ be a metric connection on it. We modify this connection by zero order terms containing a Killing field $X$:
$\nabla^{E,X}_v s = \nabla^E_v s + \langle X , v \rangle s$
Now we use Paralleltransport along geodesic and get
$\nabla^{E,X} = d + \omega$, where $\omega$ the connection one-form.
Question: Do we have $h^E(\partial_i s, s') = \partial_i(h^E(s,s')) - h^E(s,\partial_i s')$ although $\nabla^{E,X}$ is not metric?
