about
The library for AI skills.
skilldrunk is a community-ranked catalog for every piece of AI glue — Claude Skills, MCP servers, Custom GPTs, Cursor rules, prompts, and agents. Discover the best, pit two skills head-to-head, and ship.
Why a library?
AI skills are fragmented — github repos, gist dumps, Cursor forum posts, Reddit threads, vendor directories. None of them rank. None of them let the people who actually ship decide what's good.
Every format, one catalog
Claude Skills, GPTs, MCP servers, Cursor rules, prompts, agents — one type filter per skill, one vote system, one search box.
Reddit-style discussion
Upvotes bury hype; threaded comments preserve receipts. Creators can reply, defend, ship updates.
Arena, not a list
Two skills enter. Pick the one you'd actually use. K=32 Elo builds the leaderboard from crowd votes, not marketing.
AI-native APIs
REST at /api/v1, MCP at /api/mcp. Your AI client can search and vote natively. docs.
Built for AI agents, by someone who ships with them
The MCP server (npx -y @skilldrunk/mcp) plugs into Claude Desktop, Cursor, Windsurf, or any MCP-compatible client. Ask your agent: "find a Claude Skill for parsing PDFs" and it will search, read, and (with an API key) vote and comment — all through skilldrunk.
