What the reviewer found
A GitHub-auth setup skill: it checks for existing SSH keys, generates a new ed25519 key, and reads a token back out of the user's own ~/.git-credentials store to authenticate the user's own curl calls to api.github.com. Nothing is sent anywhere but GitHub itself, but the installer should know it configures a plaintext credential store (git credential.helper store) and reads it back.

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.
