spec2x: Specification-Centered Development with LLMs

A Practical Guide to Transforming Specs into Software Using AI

This guide provides hands-on instruction and conceptual grounding for leveraging Large Language Models to accelerate the process of turning technical specifications into working software. Balance the speed of AI with the rigor of a spec-first approach.

Transform Specs into Code, Faster

Discover practical techniques to go from specifications – whether functional requirements, API designs, or user stories – to generated code drafts using LLM coding assistance. Learn to apply a workflow where the specification remains the primary source of truth, enhanced by AI acceleration.

Who This Guide is For

Designed for senior software engineers, software architects, product owners, and product managers who have intermediate familiarity with AI tools and some ad-hoc experience with coding assistants. We bridge the gap between understanding the potential of LLMs and applying them effectively in development workflows.

Our Core Philosophy

At the heart of this guide is the principle of specification-centered development. We show you how to use LLMs as powerful accelerators for code generation and translation, but always grounded in and verified against a clear, robust specification. Code is secondary; the spec is primary.
