Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-03 and scored it 60/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Reads credential paths from the home directory; Destructive command against a filesystem root or device; Destructive command against a filesystem root or device. Summary: no network, touches nothing outside the project, writes no memory.
