What the reviewer found
AGENTS.md for a dev project: `<!-- bv-agent-instructions-v1 -->` is a plain section-version marker inserted by the beads_rust tooling, not a hidden instruction; the rm -rf reference is a defensive 'absolutely forbidden without explicit user reason' rule; the curl -sI call just checks the team's own Cloudflare Pages deployment.

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.
