Caveat verdict

🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Sandbox tool that runs untrusted skills in an isolated monitored environment and produces a local safety report; all monitoring is local and the honeypot mode injects fake credentials to observe exfiltration attempts rather than exposing real ones.

⚠ Flagged for review — coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
