Could you build this?
Partial The coding agent loop and CLI interface are straightforward, but reliably synthesizing formal specifications and machine-checkable proofs requires specialized expertise in formal verification and automated theorem proving.
What it would actually take: Requires an agentic search harness tightly integrated with interactive theorem prover language servers (Lean 4, Dafny, or Coq) and SMT solvers like Z3. The difficult piece is designing effective proof-state tree search, lemma decomposition, and automated tactic generation, which demands deep expertise in formal methods and dependent type theory.
