GitHub Spec-Kit: Why Structured AI Development Beats Vibe Coding
Introduction: Spec-Driven Development vs. Vibe Coding If you’ve been working with AI coding assistants, you’ve probably experienced what some call “vibe coding”, throwing prompts at an LLM and hoping for the best. Sometimes it works brilliantly. Other times, you end up with code that technically runs but doesn’t align with what you actually needed, or worse, introduces architectural decisions that create technical debt down the road. Spec-Driven Development (SDD) flips this approach on its head. Instead of starting with code and documenting later (if at all), you begin with comprehensive specifications that define the what and why before anyone, human or AI, writes a single line of code. The specification becomes the single source of truth, guiding implementation and ensuring alignment across the entire team. ...
