What the reviewer found
devenv.sh skill documentation: curl|sh is the official Nix installer from nixos.org (the project's own domain), and rm -rf .devenv/state/postgres is a project-local service-state directory cleanup step in troubleshooting docs. Purely a reference guide for a standard dev-environment tool.

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.
