# OSS Vulnerabilities — Skill Entry

This `SKILL.md` is the **entrypoint** for the OSS Vulnerabilities skill.

The skill encodes the **OWASP Open Source Software Top 10** as structured, machine-readable references
that an agent can query to identify, assess, and remediate risks associated with open source software dependencies.
