OpenSpec: Make AI Coding Assistants Follow a Spec, Not Just Guess

Github.io The most common problem with AI coding assistants isn't that they can't write code - it's that they write something different from what you had in mind. You say "add dark mode" and it rewrites CSS variables, adds a toggle button, and refactors the layout - when all you wanted was to change color tokens. Next conversation, context is gone, and it guesses your intent from scratch. OpenSpec solves this: before AI starts writing code, it produces a spec document. Both sides align on "what to do" and "how to do it", then implement according to the spec.
