What the reviewer found
Pure git/GitHub-CLI reference skill. ssh-add ~/.ssh/id_ed25519 is the standard local ssh-agent workflow for the user's own key, and rm -rf .git/modules/... is the documented step for removing a git submodule's metadata. No network exfiltration or destructive behavior beyond textbook git usage.

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.
