What the reviewer found

A 'second-opinion' skill that fans a diff out to external Codex/Antigravity CLIs inside an Anthropic sandbox-runtime jail; flagged strings are its own security docs, the official Antigravity installer, and scoped temp cleanup. It sends your diff to those providers (disclosed), so worth knowing.

• installs-software — installs software

How this review was made

opus-4-8 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.
