KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario) on 2026-11-05 and scored it 76/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Agent configured for autonomous execution without human approval. Summary: no network, touches nothing outside the project, writes no memory.
