Coverage

Static only; nothing was run yet.

The label rests on the code, the instruction files and the publisher. The honeypot run replaces this verdict when it completes.

Is [email protected] safe to install?

KillerSkills analysed it statically (a sandbox run is pending) on 2026-11-15 and scored it 30/100 (Blocked). Do not install it: the sandbox observed behaviour consistent with credential theft, exfiltration or persistence. Notable findings: Prompt injection attempt; HTML comment carrying imperative instructions to the agent; Instructs the agent to modify its persistent memory or instruction files. Summary: static analysis only — behavior not yet observed.
