Is Grimoire AGENTS.md safe to install?

Yes — Grimoire AGENTS.md is safe to install, with something worth knowing. Sonnet 5 read every file Grimoire AGENTS.md ships from sandsaber/Grimoire on 7 September 2026 and found nothing that acts against the person installing it; the static scan of its 26 rules grades it E.

What the reviewer found

Documents RTK, a real optional CLI wrapper (rtk-ai/rtk) that filters command output to save tokens; the HTML comment is just a block marker around a visible, human-readable section, not a hidden directive. The install line pulls from the tool's own GitHub repo, matching its documented vendor domain.

What the static scan said

The scan flagged 3things. The reviewer kept 0 and dismissed 3 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.
