Stop Vibe Coding: Spec-Driven Development with The BMad Method

About this episode

Brian Madison discusses the BMad Method and the importance of spec-driven development in software engineering with AI agents.

What if vibe coding is the worst thing you could do with AI agents? The developers seeing the biggest gains aren’t prompting harder. They’re planning smarter, spec-first, and treating AI as a facilitator rather than a code generation engine. In this episode, Brian Madison, creator of the BMad Method, shares how a year of late-night AI experiments led him to a structured, Agile-inspired approach to building software with AI agents. Brian explains why jumping straight into agent mode without upfront planning (what most people call vibe coding) reliably hits a wall, and how a disciplined spec-first workflow breaks through that ceiling. He walks through the BMad Method’s core workflow: brainstorming, PRD, architecture, UX design, and context-rich user stories, each feeding into the next so the agent always has exactly what it needs. Brian also recounts a transformative two-week sprint he ran with his team where engineers were given permission to fail, and how that single experiment changed the way his entire organisation works with AI. Finally, he reflects on what this shift means for the future of software engineering — where the unit of work is moving from tasks and stories to full…
