About this skill
What does the x-cmd-knowledge skill do?

This skill provides access to various knowledge search tools through x-cmd CLI, including Hacker News, Wikipedia, DuckDuckGo search, RFC documents, Project Gutenberg books, and Stack Exchange. This skill should be used when users need to search for technical information, browse online knowledge bases, or access documentation from command line interfaces.

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill x-cmd-knowledge-x-cmd-skill-2 --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 majiayu000/claude-skill-registry, a repository with 534 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.
