About this skill
What does the external-skills-catalog skill do?

Curated catalog of 60+ external Claude Code skills across 8 categories with quality rankings, install instructions, and fallback strategies

How do I install it?

Run `npx skills add vibeeval/vibecosystem --skill external-skills-catalog --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 vibeeval/vibecosystem, a repository with 521 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.
