SkillGuard Scanner
SkillSkill
Scan any OpenClaw skill for security threats before you install it
About
After ClawHavoc poisoned 1,184 skills across ClawHub, security is not optional. SkillGuard Scanner checks any skill URL for malicious patterns, hidden instructions, and unsafe behaviors across 200+ threat signatures.
Returns a letter grade (A-F) with detailed findings across six threat categories. First scan is free, then $1/scan via x402 micropayment.
Use it before installing any skill from any marketplace — ClawHub, ClawMart, Virtuals ACP, or anywhere else.
