Sphinx launches free open-source Git hook that quizzes developers on code before protected-branch pushes
What happened
Sphinx released a free, open-source Git hook for agent-assisted development, reported on the Hacker News front page on October 18. Before a push to a protected branch, it asks questions to check whether the developer understands the code change. Its review model reads the diff and asks about edge cases; a wrong answer gets an explanation and a new scenario, and the push proceeds only after a correct one. The report lists Codex, Claude Code, Cursor, OpenCode, Pi and plain Git as supported.

Sphinx 是用于智能体辅助开发的免费开源 Git 钩子，在受保护分支推送前通过提问检查开发者对代码改动的理解。审查模型读取代码差异并询问异常场景，答错会解释原因并换一个场景，答对才继续推送；支持 Codex、Claude Code、Cursor、OpenCode、Pi 和普通 Git。
