Summary: Trend analysis of SDD's emergence as the structured counterpart to vibe coding, explaining why specifications became essential as AI coding tools matured.

Editorial Notes

This is the best single article for understanding why SDD emerged specifically in 2025-2026. Breunig traces the progression from early prompt-based coding through vibe coding to the realization that AI coding assistants need structured input to produce reliable output. The key insight — that specifications are not bureaucratic overhead but the mechanism that makes AI-assisted development actually work — is argued clearly and with concrete examples.
