At ***plain dev day 26, we had the honor of hosting Johan Rosenkilde, member of the original team behind GitHub Copilot and a pioneer of spec-driven development. In his keynote, Johan contrasted agentic coding with spec-driven development.
Spec-driven development enables developers to:
• Care about specs at 1/10 the cognitive complexity
• Control and predict code changes through spec changes alone
• Collaborate effectively at the level of specs
LLMs are amazing at writing code. But writing code is not the same as developing software. If developers need to review generated code, 10x productivity remains out of reach.
The real leverage isn’t faster typing, but it’s raising the level of abstraction.
