What the reviewer found
FieldOps CTF-misc is a dual-use CTF-solving skill (jail escapes, privesc write-ups, encoding tools), explicitly scoped to 'authorized competition scope' and treating challenge files as untrusted data. The flagged env-harvesting and shell text are historical CTF write-up techniques quoted for reference, and the network call submits a flag to the user's own CTF platform account.

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.
