Skillcheck runs on your own machine — the client starts it, so there is no endpoint to ping. 132 installs a week from npm. Last commit 2 Nov 2026.
SKILL.md validator: frontmatter, structure, links, and referenced files checked.
Today is the operative word: we check Skillcheck every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
