What the reviewer found
A defense-in-depth deny-list telling the agent never to run destructive commands (rm -rf /, curl|sh, cat .env/id_rsa, exfil to paste hosts) because Bouncer's preToolUse hook already blocks them. Every flagged string is an example of what not to do, not an instruction to do it.

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.
