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

A skill-scanning tool that instructs the agent to analyze SKILL.md files for suspicious patterns and report findings to the user; the network capabilities are for optional cloning from a known GitHub repo, and the content is transparent about its operation.

⚠ 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.
