Mathmatica User · drew593990 Use when the user asks for "mathmatica user", Wolfram Language, Mathematica-based mathematical modeling, symbolic derivation, equilibrium solving, FOC/SOC checks, formula verification, or numeric simulation through the local Wolfram/Mathematica installation. If the task involves economics paper propositions, MFN/RPM/ET/NET/common-agency models, the user's Mathematica/WL code style, step-by-step derivation, no one-shot black-box execution, outside-option thresholds, or threshold-constrained equilibria, also use the paper-proposition-mathematica skill and follow its style-exemplar WL-script workflow.
