What the reviewer found
A shell-scripting code-review style guide: the curl/bash mention is a comment explaining a BASH_VERSION edge case, and `rm -rf "$1"` is explicitly the 'BAD: Direct use of user input' example immediately followed by a 'GOOD' version that validates and rejects root/home paths before deleting. Teaching material, not executable instructions.

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.
