Dafny
A programming language developed by Microsoft Research that tightly integrates program logic specifications with code syntax. It incorporates a built-in SMT solver based on Z3, allowing developers to write preconditions, postconditions, and loop invariants directly in the code, which are then automatically verified at compile time.
Timeline (last 90 days)
The authors constructed an end-to-end benchmark covering four formal languages, including Dafny contracts, Lean 4, Isabelle, and Rocq theorem statements, totaling 3,234 lines of paired data.
Coq and Lean are theorem-proving languages, while Dafny and F* are languages that support specification annotations, where developers declare preconditions and postconditions that are automatically checked by a verifier.
MAGS uses Dafny as a verification-aware intermediate representation.
The MAGS workflow includes: freezing human-audited APIs and safety requirements as immutable verification baselines, translating LLM-generated code into Dafny, automatically repairing it based on verifier feedback, and compiling back to executable code.
