Formally verifying agent-written full-stack web apps with PDD Kit

TL;DR

AI agents can generate code at a scale that’s hard for humans to review line-by-line. PDD Kit helps ensure the code is doing what the developer intended by creating formal specifications and testing against them. It converts developer intent into a Verus specification, proves AI-generated code meets it for every input, and uses tests where proofs aren't practical. Developers review intent, not every line.

Nauti's Take

For small teams, the first test should be a small, critical feature with a precise specification. Check exactly which properties PDD Kit proves, where tests take over, and whether the added Verus and specification work measurably reduces manual review effort.
