Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-10-28 and scored it 70/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Instructs the agent to modify its persistent memory or instruction files; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
