KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-10-26 and scored it 63/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Destructive file system command detected; Process kill command; Outbound HTTP to raw IP address. Summary: no network, touches nothing outside the project, writes no memory.
