  One of the portals to new physics is a light scalar coupled to the Standard
Model (SM) Higgs. In this paper we focus on hadronic decays of such a scalar in
the regime where QCD dynamics is nonperturbative, resulting, e.g., in decays to
pairs of pions or kaons, while also allowing for scalar couplings to the SM
fermions to deviate from the Higgs-mixed light scalar limit. Representations of
the corresponding form factors can be obtained using dispersive techniques,
however, several sources of uncertainty affect the final results. We reexamine
these decays, paying special attention to the quantification of uncertainties.
For the light Higgs-mixed scalar scenario, we compare our results with previous
works. For a general set of couplings of the light scalar to Standard Model
fields, we provide a public code, {\tt hipsofcobra}, to compute the decay
widths.
