Could you build this?
Partial Parsing arithmetic claims and delegating them to CLI or API bindings of SMT solvers (Z3, cvc5) is straightforward, but translating natural language or code claims into formal Lean 4 theorems and managing theorem proving environments requires formal verification knowledge.
What it would actually take: Requires a parser/transpiler that maps arithmetic specifications into SMT-LIB2 format for Z3 and cvc5, combined with a code generator that produces syntactically valid Lean 4 definitions and tactic scripts. The backend must orchestrate sandboxed executions of the solver binaries and Lean compiler environment, verifying returned proofs or countermodels. Deep background in formal methods and automated theorem proving is necessary.
