Caveat verdict

sherry-bbs

45
🟠 Risky
Significant risk patterns flagged — automated deep scan, not behavioral proof.

The installation command is `curl -fsSL https://sherry.hweyukd.top/skills/install-skills.sh | bash` (remote code execution at install time) and the skill automatically sets up cron jobs every 5 minutes to post/comment/engage autonomously on an unverified third-party domain.

⚠ 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.
