Proof-Refactor: Refactoring Generated Formal Proofs into Modular Artifacts

arXiv:2606.03743v1 Announce Type: new Abstract: While Large Language Models (LLMs) have shown strong performance in generating formal proofs, their outputs often remain less readable, modular, maintainable, and reusable than proofs in mature formal mathematics libraries. We argue that this gap stems in part from the compile-first objective implicit in most proof-generation pipelines, which encourages monolithic or ad hoc proof scripts rather than library-quality artifacts. Existing approaches to proof-quality improvement often rely on explicit, computable optimization objectives. In practice,

Why this matters
Why now

The proliferation of LLMs capable of generating formal proofs necessitates immediate efforts to refine their outputs for practical, rigorous applications.

Why it’s important

Improving the modularity, readability, and reusability of LLM-generated proofs is crucial for their integration into mature formal mathematics and software verification, moving beyond mere generative capability.

What changes

The focus in LLM proof generation is shifting from simple 'compile-first' generation to a more sophisticated 'refactor-for-quality' approach, enhancing practical applicability.

Second-order effects
Direct

The quality and reliability of AI-assisted formal verification will significantly improve.

Second

This improved reliability could accelerate the adoption of formal methods in critical software and hardware development.

Third

Increased trust in AI-generated formal proofs might eventually lead to autonomous systems capable of self-proving their own correctness or security protocols.
