What the reviewer found

fly.io deployment skill. `curl -L https://fly.io/install.sh | sh` is fly.io's own official installer, and `rm -rf /var/lib/apt/lists/*` is the standard Docker apt-cache cleanup line inside a Dockerfile, not a destructive action on the host.

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.
