Why TrustSkills for OpenClaw users

TrustSkills is purpose-built for users evaluating ClawHub skills before installation. It requires no account, stores no data, and returns findings in plain English — not CVE IDs or security jargon that requires a security engineer to interpret.

Where Snyk and Mondoo are enterprise products with free tiers, TrustSkills is free first. Where SkillRisk is entirely client-side, TrustSkills runs checks server-side with a detection engine that can be updated independently of the client.

The roadmap includes hash drift monitoring, weekly digest emails, Slack alerts, and EU AI Act compliance reports — the features enterprise teams need as they move from evaluation to production.
