Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-10-26 and scored it 67/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: npx invocation of non-well-known package; npx invocation of non-well-known package; Python subprocess execution detected. Summary: no network, touches nothing outside the project, writes no memory.
