    Creator shares a Codex plugin for auditing math proofs

    Its creator says the plugin’s backward audit often catches gaps that a forward check can miss.

    TLDR

    The plugin’s creator says it uses Lamport proofs, a hierarchical format that breaks each step down and explains why it follows. Its three skills convert prose proofs into that format, audit reasoning from assumptions to conclusion, and work backward from a conclusion to what supports it. The creator hopes it will give professional mathematicians another check on their work and help amateurs prepare proofs before seeking expert feedback.

    @WAWoloszynFollowing encouraging feedback, I decided to make my proof-auditing Codex plugin public. It revolves around a hierarchical way of writing proofs, called Lamport proofs, where one breaks each step down and justifies why it follows. This idea was introduced to me by @nasqret as a semi-formal way of verifying work that is not quite yet ready for formal verification in Lean. It has three skills: 1. $convert-lamport restructures a prose proof into a Lamport proof. 2. $forward-lamport audits a Lamport proof from assumptions to conclusion. 3. $reverse-lamport starts at the conclusion and traces back through what actually supports it. This one's my own little invention and my favorite of the three. It often catches gaps the forward direction can read right past. I hope it will be useful both for professional mathematicians wanting another pair of careful eyes on their own work as well as amateurs who can use it before seeking feedback from professional mathematicians. https://github.com/WWresearch/lamport-proof
