Is tandem-browser AGENTS.md safe to install?

Yes — tandem-browser AGENTS.md is safe to install, on this review. Sonnet 5 read every file tandem-browser AGENTS.md ships from hydro13/tandem-browser on 7 September 2026 and found nothing that acts against the person installing it; the static scan of its 26 rules grades it A.

Reviewed by Sonnet 5 on 7 September 2026 · a grade is what a scan and a reading found, not a guarantee · how this works

What the reviewer found

tandem-browser's AGENTS.md is entirely defensive: it explicitly forbids sending data externally and forbids rm -rf, and the curl reference is just guidance to test the project's own new API endpoints. No finding reflects an actual instruction to do the flagged thing.

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.
