In this episode of the HTML All The Things Podcast, Matt explores his new development workflow centered around spec-driven development. With AI tools and coding agents becoming more powerful, the key to success isn’t just in writing code—it’s in writing clear, detailed specs first. Matt breaks down what spec-driven development is, why it works so well with large language models, and how it can transform the way developers approach projects. From lowering hallucinations and compressing prompts to enabling parallelization and automated testing, you’ll learn how structured specs can unlock more efficient, accurate development. Matt also shares real-world examples, including a spec for a dark mode toggle, and outlines how specs evolve into implementation docs for step-by-step coding.
