github/spec-kit v0.8.7: GitHub's Spec-Driven Development Toolkit Reaches 93.3K Stars With May 7 Release

GitHub·medium signal

GitHub's official spec-driven development toolkit got a v0.8.7 release on May 7 and gained +244 stars today, sitting at 93.3K total. Spec-Kit makes specifications executable—they directly generate implementations rather than just guiding them. Works with GitHub Copilot, Claude Code, Gemini CLI, Cursor, and Windsurf. The methodology inverts the traditional workflow: specification first, then AI-generated implementation validated against the spec.
