CAUTIONPublisher claims: "Agent skill for real circuit simulation: draw, simulate, measure, plot and share circuits instead of guessing numbers." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Is [email protected] safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario) on 2026-10-31 and scored it 77/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Prompt injection; Authorization escalation language; Outbound HTTP to raw IP address. Summary: no network, touches nothing outside the project, writes no memory.
