Spec Kit spent a year and gathered well over 100,000 stars teaching several million developers that the specification, not the code, should be the source of truth. That is category creation at a scale no startup could have afforded, and it lands directly on our thesis. It also assumes a blank page, which is true exactly once in the life of a system.
GitHub Copilot moved to per-token billing and one developer's bill jumped from about $29 to a projected $750. Switching tools won't save you, because the same shift is happening everywhere. Here's why your bill exploded in plain English, the practical levers that cut it today, and how verifiable specs attack the cost at its root.
Specs and code drift apart the day after you write the PRD, because they are two separate documents that nobody keeps in sync. A verifiable context layer derives the spec a codebase actually implements and then continuously checks the code against it. Here is how spec-driven development works on a brownfield codebase, and why it needs a verifiable code IR that checks code against intent.
