What the reviewer found
WhatsApp setup skill: the curl|bash is the official bun.sh installer, the wacli binary download is checksum-verified against a pinned SHA256 before use, rm -rf only clears a mktemp temp directory, and the settings.json edit adds an 'ask' rule (not a grant) so sends require explicit user approval. This installs two known third-party tools but does not exfiltrate anything or weaken permissions.

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.
