Use This Skill
See what a skill does, and scan it, before you install it
A directory of 1,409 agent skills for Claude Code, Codex and Cursor. Every skill is scanned for the nine patterns a skill should never need, with the file and line shown. Seventeen are proven: the same brief run with and without the skill, three times each, all results open. Run the same scan on your own repo in one command or on every pull request, free for public repos. Teams scan private repos for $29 a month. A free MCP connector lets your agent search, check and install from the chat.
Hi everyone, I'm Tineessa. I built Use This Skill because star counts told me which skills were popular but never what they actually changed.
Each proof runs one brief through Claude twice on the same model, once without the skill and once with it, and publishes both results as live pages with the skill's exact commit recorded, so you can judge the difference yourself or repeat the run.
The directory and install commands are free, and the first proof is free to try. I would like to know which skills you want proven next.
