Security Vetted
Skills that earned the Shield
The Shield is granted to popular, high-quality skills that pass our deep security scan: static analysis of the actual code for dangerous patterns, a check of every dependency against the OSV vulnerability database, and an LLM safety review. It is earned, never bought, and re-checked on a schedule. How vetting works.
