9 AI Tools to Fix AI Coding's Spec Mismatch Problem

Spec-driven development (SDD) treats structured specs as truth and generates code from them, preventing AI agents from producing fast but wrong code. Top tools like Kiro (agentic IDE), GitHub Spec Kit (93k stars CLI), and BMAD (12+ agents) enforce phases like requirements, design, tasks for traceable outputs.
