Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-04 and scored it 57/100 (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; HTML comment carrying imperative instructions to the agent; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
