What the reviewer found
Meta-skill for installing the clank tool itself; the installer pulls from clank's own GitHub repo and rm/ls target its own clone directory, not other tools' secrets. [SC2 kept: remote script from raw.githubusercontent.com piped to a shell]

How this review was made
Sonnet 5 read the files above on 6 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.
