又一家大厂，建起了自己的代码防火墙。 文 | 超聚焦 近日，据鞭牛士报道，相关人士爆料称，快手的研发线发布通知，对几款第三方编程软件收紧了使用权 限。不少同学发现，只要在自己办公电脑上点开Cursor，它就直接闪退，根本用不了。 这导致一些早已将AI编程工具深度融入日常开发流程的工程师措手不及。主力辅助工具的突然失效， 不仅打断了高度自动化的编码节奏，也让许多原本由AI即时补全或生成的环节被迫回归手动操作，整 体开发效率明显下滑。 原本几分钟就能自动生成的模板代码，现在又得手动敲；原本靠自然语言描述就能完成的函数逻辑，如 今不得不重新翻文档、查API。效率断崖式下跌，工作流被打断，甚至员工调侃："没Cursor的日子，我 连Hello World都写不顺了。" 而这其实并非孤例。在过去两年中AI工具从"新奇玩具"迅速演变为"开发标配"的过程中，越来越多技术 团队开始面临一个两难命题：一边是肉眼可见的效率跃升，一边是难以量化的安全隐忧。 当一行由远程模型生成的代码可能携带着未知的数据回传、训练偏见甚至知识产权瑕疵，企业不得不重 新评估——所谓"智能辅助"，边界究竟该划在哪里？ 那么，类似的情况在其他大厂是否也已 ...
