AI coding assistants have made developers incredibly fast since the start of the AI boom, but this new speed often comes at a hidden cost. The IT industry is realizing that generating code is the easy part. The real challenge is building systems that are coherent, maintainable, and actually do what they were supposed to do.
This is where Spec-Driven Development (SDD) comes in. This methodology shifts the focus from vibe coding to following the general intent, using specifications as the new source of truth for AI-assisted engineering.
