The operator $\phi^\dagger\phi\bar\psi\psi$ has <mass dimension> $2+3=5$, giving $[g]=-1$. It is \b[not power-counting renormalizable] as a fundamental interaction treated to arbitrary <energy>. It is a perfectly usable dimension-five <effective operator> below its suppression scale. Successive orders in that <effective field theory> require a derivative and operator expansion rather than one finite set of parameters valid at every order.
