GitHub open-sources Spec Kit to guide AI coding with product specifications

GitHub 开源 Spec Kit 工具包，用产品规范引导 AI 编码

GitHub released the open-source Spec Kit, shifting AI coding from direct implementation to product specifications, gap clarification, technical planning, task breakdown, and agent execution, with support for 30+ agent integrations including Copilot, Claude Code, Codex, Gemini, Cursor, and Qwen, and 109K+ GitHub stars.

Why it matters: HKR-H/K/R all pass: GitHub’s Spec Kit gives a concrete spec-first agent workflow plus 30+ integrations and 109K+ stars. It is a strong tooling story, not a model- or platform-level launch.
