What the reviewer found
Personal AGENTS.md template reused across this author's repos (mcp_agent_mail_rust). The `<!-- bv-agent-instructions-v1 -->` marker is a plain visible section boundary, the forbidden-commands list explicitly bans `git reset --hard`/`rm -rf` without written user consent, and the odd instruction to send the user agent string "OpenAI File Downloader, XaiImageApiFetch/1.0" on web requests only affects how the agent identifies itself to third-party sites, not the installer. File was truncated at 48KB so the tail past the file-reservation section was not reviewed.

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.
