What does the CTF•开源情报 skill do?
用于公开资料检索、社交媒体分析、地理定位、DNS、用户名枚举、反向图片搜索、历史快照、公开记录与坐标识别等 OSINT 类 CTF 题;触发名:ctf-osint
How do I install it?
Run `npx skills add asdfgh1445/ctf-super-hub --skill ctf-osint --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From asdfgh1445/ctf-super-hub, a repository with 718 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
