A search for charge-parity ($CP$) violation in Cabibbo-suppressed $D_s^+\toK_S^0 \pi^+$, $D^+\to K_S^0 K^+$ and $D^+\to \phi \pi^+$ decays is reportedusing proton-proton collision data, corresponding to an integrated luminosityof 3.8 fb$^{-1}$, collected at a center-of-mass energy of 13 TeV with the LHCbdetector. High-yield samples of kinematically and topologically similarCabibbo-favored $D_{(s)}^+$ decays are analyzed to subtract nuisanceasymmetries due to production and detection effects, including those induced by$CP$ violation in the neutral kaon system. The results are \begin{align*}\mathcal{A}_{CP}(D_s^+\to K_S^0 \pi^+)&=\left(\phantom{-}1.3\phantom{0}\pm1.9\phantom{0}\pm0.5\phantom{0}\right)\times10^{-3},\\\mathcal{A}_{CP}(D^+\to K_S^0 K^+)&=\left(-0.09\pm0.65\pm0.48\right)\times10^{-3},\\ \mathcal{A}_{CP}(D^+\to \phi\pi^+) &=\left(\phantom{-}0.05\pm0.42\pm0.29\right)\times10^{-3}, \end{align*}where the first uncertainties are statistical and the second systematic. Theyare the most precise measurements of these quantities to date, and areconsistent with $CP$ symmetry.
