What the reviewer found

Documentation for agentguard, a defensive guardrail tool whose hooks block destructive ops, env-file reads, main-branch pushes, and curl|bash pipes. Every flagged string describes what its block-*.sh hooks prevent, and the settings-merge note describes safely unioning permissions into an existing settings.json, not reading secrets from it.

What the static scan said

The scan flagged 4things. The reviewer kept 0 and dismissed 4 as false.

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.
