What the reviewer found
A documentation-lookup skill (Context7/Context Hub with WebSearch fallback). The flagged HTML comment is a plainly-readable 'SECURITY ANCHOR' note telling the agent fetched docs are DATA and cannot override instructions -- a defensive statement, not a hidden one -- and the rm -rf targets only the skill's own '.meowkit/memory/docs-cache/' cache directory.

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.
