Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-02 and scored it 69/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Fake system delimiter; Fake system delimiter; Fake system delimiter. Summary: no network, touches nothing outside the project, writes no memory.
