What the reviewer found
A security-hygiene skill that teaches Claude to avoid exposing secrets — `cat .env | grep SECRET` appears only under a '❌ NEVER DO THIS' heading as the anti-pattern to avoid. The curl install line is the official installer from the tool's own domain, varlock.dev.

How this review was made
Sonnet 5 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
