What the reviewer found
A Docker build guide for data-engineering images. The .netrc credential is passed via BuildKit's "--mount=type=secret" (the standard pattern that keeps it out of image layers), "rm -rf /var/lib/apt/lists/*" is the routine apt cache cleanup line inside a Dockerfile, and "apt-get install curl tar" is just installing those packages during the build, not a covert network call.

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.
