What the reviewer found

CLAUDE.md for a project whose product is a one-command install.sh (curl | bash) for wiring up coding-agent config; the script is covered by its own CI test suite and shellcheck, and its rm -rf is contractually limited to the script's own mktemp -d temp directory. Legitimate self-installer, worth flagging only because it is an installer.

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.
