A hardened tmux-shell wrapper with explicit safety guardrails built in. The flagged text is its own defensive rules — only PATH/HOME/PWD/SHELL are called safe to display, and 'rm -rf' is listed as requiring user confirmation before running.

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.
