Open-source AI coding agent Forall generates provable code
Hacker NewsJul 16, 2026 · 8h ago
Forall is an coding agent that produces machine-checkable proofs alongside the code it writes. Instead of just generating code that a person then has to test, Forall uses tools like Lean and Dafny to mathematically prove that the generated code actually behaves as specified.
The project is early-stage, currently supporting proof verification for only three s. The creators are seeking feedback specifically from people interested in , Lean, Dafny, or in general.
