Key Points

To establish how chemical bonding and electronic instabilities enable the development of centrosymmetric skyrmion materials.
Analyzed chemical bonding features, focusing on antibonding states, across the GdRu2X2 (X = Si, Ge, and Sn) material family.
Evaluated the electronic instabilities that drive the stabilization of magnetic skyrmion states.
Demonstrated that electronic instabilities linked to specific chemical bonding motifs create a pathway to stabilize skyrmions.
Established a framework for engineering centrosymmetric skyrmion materials under conditions previously thought unattainable.
