There are thousands of agent skills on GitHub, and most agents never use the right one. Alyn fixes that. Connect it once to Claude Code, Cursor, Codex or any MCP client. For every task, your agent asks Alyn which skill fits, loads it and follows it. No browsing, no copying folders around.
Alyn knows 6,134 open source skills by 445 creators and ranks them by GitHub stars, real installs and the quality of each SKILL.md. The data refreshes every night, and this README every Monday.
Why skills matter
A small model with the right skill beats a big model without one.
On SkillsBench, Claude Haiku 4.5 with skills solved 27.7% of tasks. Claude Opus 4.5 without skills solved 22.0%. Given skills, Opus itself jumped to 45.3%. Curated skills added 16.2 points on average.
So the skill matters as much as the model. Alyn makes sure your agent has the best one for the job, and lets you run cheaper models for more of your work.

The agent calls find_skills, picks the best match and loads it for the current session. To keep a skill for good, it calls install_skill. All tools →
