The analysis provides analytical expressions for inflationary observables such as the spectral index ($n_s$), the tensor-to-scalar ratio ($r$), and the local-type nonlinearity parameter ($f_{\\rm NL}^{(\\rm local)}$). The presence of the assistant field leads to a lowering of $n_s$ and $r$ in most of the parameter space, compared to the original predictions. In some cases, $n_s$ may increase due to the assistant field.
