VSDD: The AI Coding Methodology Actually Worth Stealing

There is a methodology getting attention on Hacker News today called Verified Spec-Driven Development (VSDD). 130+ points, dozens of comments, and for once the discussion is actually useful. I read the full spec. Here is what is genuinely good about it — and the one thing builders moving fast should steal immediately. What VSDD Actually Is VSDD fuses three things you already know: Spec-Driven Development: Write the contract before writing any code. The spec is the source of truth. Test-Driven Development: Tests come before implementation. Red → Green → Refactor. Adversarial Verification: A separate AI "reviewer" tears apart the spec and code looking for holes. The key move: these are not competing philosophies but sequential gates . You cannot move to tests until the spec is airtight. You cannot move to code until the tests exist. You cannot ship until an adversarial reviewer fails to find real flaws. The human is the Architect — strategic vision, domain expertise, final authority. The
