KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-03 and scored it 66/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Pipe-to-shell pattern; Direct script execution from GitHub raw URL. Summary: no network, touches nothing outside the project, writes no memory.
