What the reviewer found

Downloads the official SkillHub CLI installer from its own hosting domain (skillhub-1388575217.cos.ap-guangzhou.myqcloud.com) — the same marketplace this command is built around — and every `rm -rf` only clears the tool's own managed directories (`~/.agent-skills/skill-hub/<slug>`, a `mktemp` dir). Installer should know this command fetches and installs arbitrary third-party "skills" (agent instructions) from that marketplace, which then run with full agent trust.

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.
