  Recent works argue that the pattern of chiral symmetry breaking in QCD-like
theories can be derived from supersymmetric (SUSY) QCD with perturbation of
anomaly-mediated SUSY breaking (AMSB). Nevertheless, despite the fact that AMSB
needs to be a small (but still exact) perturbation, there are two other major
problems remaining unsolved: first, in order to derive the chiral symmetry
breaking pattern, one needs to minimize the potential along a certain specific
direction, identifying this direction fully as an outcome is nontrivial given
the moduli space of degenerate vacua in the SUSY limit; second, when SUSY is
broken, non-holomorphic states might emerge and be relevant for determining the
vacuum structure. In this work, we focus on SUSY QCD with $N_f\leq N_c+1$ and
perturb the theories using AMSB. Without minimizing the potential along a
certain specific direction in the moduli space, we successfully derive the
expected chiral symmetry breaking pattern when $N_f<N_c$. However, when
$N_f=N_c$ and $N_f=N_c+1$, we show that tree-level AMSB would induce runaway
directions, along which baryon number is spontaneously broken, and the vacua
with broken baryon number can be deeper while the field values are not far from
the origin. This implies that phase transitions and/or non-holomorphic physics
are necessary. Moreover, we perform explicit consistency checks on ultraviolet
insensitivity for different $N_f$ by adding the holomorphic mass term for the
last flavor, we find that the jump of AMSB potential indeed matches the
contribution from the holomorphic mass term. We also show in general that, when
tree-level AMSB is not vanishing, the origin of the moduli space in s-confining
theories does not persist as a minimum.
