The article explains Spec‑Driven Development (SDD), a methodology that defines requirements, system behavior, constraints, and tasks in a specification document before AI generates code, compares it with Test‑Driven Development, lists common SDD frameworks, and outlines suitable and unsuitable scenarios.
This article walks through a six‑step, AI‑augmented review‑driven development workflow—using Spec‑Kit commands, devil‑style iterative reviews, and TDD—to turn a simple "user login failure lock" requirement into a robust, well‑tested implementation while catching design flaws early.
Amid growing AI‑coding hype, this article examines why Specification‑Driven Development (SDD) remains essential and provides a detailed analysis of five popular open‑source SDD frameworks—SpecKit, BMAD, OpenSpec, Superpowers, and GSD—covering their core concepts, installation steps, typical workflows, strengths, weaknesses, and recommendations for teams of different sizes.
Superpowers introduces subagent‑driven development (SDD) to split execution into isolated tasks, each handled by a fresh sub‑agent with a mandatory spec‑compliance review followed by a code‑quality review, preventing error amplification, bias, and unchecked assumptions in AI‑assisted coding.
