中文介绍

以下内容整理自卡兹克的介绍文章：《开源项目简介：last30days》

这是什么？

给 last30days 一个话题，它让 AI agent 帮你扒一遍最近 30 天国外各大社交媒体上的真实讨论，然后综合成一份带引用的报告。

开源地址：https://github.com/mvanhorn/last30days-skill

和普通搜索的核心差异

第一，深度爬取，不只是看帖子标题。

Reddit 上一个帖子，它把评论带点赞数一起扒下来。X 上的推文，高赞回复也会纳入进去。就像你看小红书不会只看正文肯定要翻评论区一样，这个 Skill 把类似的考虑了进去，而且跨十几个平台一起翻。优质信息经常就埋在评论里，有时候评论比正文还值钱。

第二，按真实热度排序，不按 SEO。

Reddit 几千 upvote 的讨论，权重高于一篇没人看的博客。一个 3.6M 播放的 TikTok，权重高于一篇新闻稿。看到的排名是真人投出来的，不是哪篇博客做了 SEO 排上来的。

覆盖源

Reddit、X、YouTube、TikTok、Hacker News、GitHub、Polymarket 等十几个国外平台。

免费 vs 付费

  • 零配置免费可用：Reddit、Hacker News、Polymarket、GitHub
  • 简单配置后可用：X（登录浏览器账号或用 API key）、YouTube（装 yt-dlp）
  • 免费源对日常学习新概念来说已经够用

适用场景

学习 AI 新概念新知识特别好用——国内很多信息是对海外资讯的搬运和二次咀嚼，直接用这个 Skill 从源头获取，信息更一手、更及时。
