Is spawn-instance safe to install?

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

What the reviewer found

Skill that forks the Aeon repo into a new GitHub instance for the user, with an explicit security model that never propagates secrets to the child. The flagged HTML comment is internal authoring metadata (which auto-generated variant this file is), and `rm -rf "$TMPDIR"` only deletes a directory the script itself created via mktemp.

What was read

The file as it ships in aaronjmars/aeon-agent:

What the static scan said

The scan flagged 2things. The reviewer kept 0 and dismissed 2 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.
