Optical skyrmions exhibit structured polarization textures, but extended side lobes hinder spatial isolation. We design a compact silicon metasurface generating a spatially confined skyrmion using a truncated Bessel target and full-wave adjoint optimization. The device achieves field overlap above >88% and a skyrmion number Nsk ≈ 0.97 at λ = 1550 nm.
