What the reviewer found
Bun runtime skill doc: the curl is bun.sh's own official installer and the rm -rf only removes node_modules/package-lock.json during a Node-to-Bun migration walkthrough. Nothing reaches outside the machine or deletes outside the project.

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.
