GitHub's open-source Spec Kit, an MIT-licensed toolkit for spec-driven development, has surpassed 72,000 stars with strong community momentum. The four-phase gated process (Specify → Plan → Tasks → Implement) works with 22+ AI agent platforms including Claude Code, Copilot, Amazon Q, and Gemini CLI. It formalizes the emerging pattern of writing specs as the source of truth before letting AI agents generate, test, and validate code.
