GitHub Releases spec-kit: AI Writes the Spec First, Then Builds — 'Vibe Coding Is Dead'

X (GitHub)·medium signal

GitHub released spec-kit, an open-source tool that inverts the vibe coding workflow: describe an idea, AI writes a formal spec, generates a plan, then builds — working with all major AI agents. The announcement tweet framing 'vibe coding is dead' has 940 likes and 65K+ views, positioning spec-first development as the responsible evolution beyond prompt-and-pray. If accurate, this represents a significant product move by GitHub into structured AI-assisted SDLC alongside Copilot.
