If you have used an AI coding agent — Copilot, Claude Code, Gemini CLI — you have probably lived this moment: you describe a feature, the agent produces code that compiles and looks right, and then it quietly does the wrong thing. The agent is not weak; the input was ambiguous. We have been treating coding agents like search engines when they behave more like very literal pair programmers.
Spec-Driven Development (SDD) is the answer to that problem: instead of jumping straight to code, you write down what you want and why, refine it, and only then let the implementation follow. The specification — not the code — becomes the center of the project.
