Look up a skill
Paste a GitHub link to an agent skill and see whether the skill index has a page for it. The lookup runs in your browser.
It takes a github.com link to a repository, a skill's folder or its SKILL.md, or a raw.githubusercontent.com link to a SKILL.md.
The lookup needs JavaScript. Without it, every skill the index lists is on the list page.
What it reads and sends
This page sends the link you paste nowhere. The lookup reads one file from this site, the list at /skills/. Your browser's own features, such as spell check, autofill and page translation, are outside what this page controls.
No model is called, so the lookup spends no tokens.
A match shows that skill's entry as the list shows it, and nothing more. A link the list has no page for gets a line that says so. Each result names the folder the link was read as: a branch name that holds / is read as its first part.
Like every page on this site, this one counts a visit with Cloudflare Web Analytics. The lookup does not write the link into the page's address, title, cookies or storage.
