  In this talk, I present the minimal classically scale-invariant and
$CP$-symmetric extension of the standard model, containing one additional
complex gauge singlet and three flavors of right-handed Majorana neutrinos,
incorporated within a renormalizable framework of gravity, consistent with
these symmetries; the Agravity. I particularly focus on the slow-roll
inflationary paradigm within this framework, by identifying the
pseudo-Nambu-Goldstone boson of the (approximate) scale symmetry with the
inflaton field, constructing its one-loop effective potential, computing the
slow-roll parameters and the inflationary observables, and demonstrating the
compatibility of the small field inflation scenario with the latest Planck
collaboration data sets.
