Using Spec-Driven Development for Production Workflows - Erik Hanchett, AWS

Spec-driven development is a structured approach where developers create detailed specifications and design documents (in markdown format) before writing any code, which guides AI coding assistants to produce higher-quality code by providing clear context and requirements; this method works well with large language models by establishing a 'Goldilocks zone' of information, using skills for specific instructions, and maintaining human oversight as the code reviewer, with tools like Kiro's spec mode helping break down complex tasks into requirements, design documents, and implementation tasks including property-based tests.
