What the reviewer found
Guidance for matching a Python environment to an NLP research repo before installing its dependencies: the flagged curl line is the official uv installer from astral.sh pinned to 0.9.7, and the rm -rf clears /var/lib/apt/lists after apt-get, the standard Docker cleanup. Nothing reaches outside the machine, but following it runs apt-get and installs uv and a Python toolchain.

How this review was made
Fable 5.1 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.
