MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs installing and then "Read the installed SKILL.md files" from the remote package installed via "npx -y skills add vercel-labs/agent-skills", so content fetched from vercel-labs/agent-skills (installed at runtime) would be read and applied to generation rules and thus can directly control agent instructions.
