Skills.sh

Cross-agent skill registry with a one-command installer

Tier A · StrongDirectoryRegistryAgent Skillskills.sh

Skills.sh indexes agent skills published on GitHub and installs them into whichever coding agent you use with `npx skills add <owner/repo>`. The front page is a live install leaderboard (All Time / Trending 24h / Hot / Official) — over 1.2 million installs recorded, with 600 ranked skills in the page payload and topic browsing across React, Next.js, Design & UI, Mobile, Agent workflows, Databases, Testing and Marketing. It writes config for more than twenty agents including Claude Code, Cursor, Codex, GitHub Copilot, Windsurf, Gemini, Cline, OpenCode, Zed, Goose and Kiro CLI, and also ships Packs, per-agent pages, audits, a CLI doc and an API.

Install

npx skills add <owner/repo>

For an agent

Use this when the user asks for a skill by capability and you do not already know its repo — `npx skills add <owner/repo>` resolves and writes the config for the host agent, so prefer it over telling the user to clone a repo into .claude/skills by hand. It is stack-wide rather than design-specific: for UI and design-engineering work, cross-check ui-skills.com first, which curates the same underlying SKILL.md files with far more editorial filtering. Treat the leaderboard as popularity, not quality — install counts are dominated by a handful of vendor bundles (Feishu/Lark alone occupies a dozen of the top slots), and skill licences vary per repo, so read the SKILL.md before you run it.

Why it is here. The closest thing the agent-skill ecosystem has to npm's front page, and the only installer that normalises one command across twenty-plus coding agents.

Provenance

Verified 2026-08-15. HTTP 200. https://skills.sh (WebFetch plus raw HTML, from which 600 leaderboard entries and the agent list were parsed), https://skills.sh/docs/cli, https://skills.sh/skills. https://skills.sh/llms.txt returns the Next.js 404 shell and https://skills.sh/leaderboard is 404, so no machine index was confirmed beyond /docs/api; 600 is the count present in the page payload, not a stated catalogue total.
