What the reviewer found
Skill that builds a personal course-authoring skill from the user's own classroom/chat history via search/read/ask_user/create_skill tools, with explicit rules to treat history as untrusted evidence and never fabricate; no findings, benign.

What the static scan said
The 26-rule scan found nothing in this file; the review read it anyway.
How this review was made
Sonnet 5 read the files above on 6 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.
