Understand

We present the action and transformation rules of Poincare supergravity coupled to chiral multiplets $(z^\alpha, \chi^\alpha, h^\alpha)$ with off-shell auxiliary fields.

Starting from the geometric formulation of the superconformal theory with auxiliary fields, we derive the Poincare counterpart by gauge-fixing the Weyl and chiral symmetry and S-supersymmetry.
We show how this transition is facilitated by retaining explicit target-space covariance.
Our results form a convenient starting point to study models with constrained superfields, including general matter-coupled de Sitter supergravity.
