All known higher-spin theories are uniformized by a simple system of equations. The equations and their gauge invariance are encoded in two superalgebras and have a natural algebraic meaning. For a given theory these algebras can be inferred from the algebra of vacuum symmetries (higher-spin algebra) and its subalgebra surviving at the interaction level. We demonstrate that the proposed system of equations admits a concise and algebraically transparent AKSZ formulation. Furthermore, based on this formulation it can be related to a constrained Hamiltonian system describing a boundary singleton.
