Stop Vibe Coding. Use Spec-Driven Development Instead.

Vibe coding is how juniors ship bugs fast. You describe a feature in natural language, the AI generates code, you tweak until it works. Fast? Yes. Scalable? No. At scale, vibe coding gives you: 500 lines of unreviewable code Features you didn't ask for An agent that rewrites half your codebase The fix: Spec-Driven Development Senior engineers don't prompt AI directly. They write specs first. Three documents you need: 1. PRD (Product Requirements Doc) - what you're building and why 2. Technical Design Doc - architecture, data models, API contracts 3.
