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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires running an install at runtime via "npx skills add microsoft/frontend-design-review", which will fetch and execute remote package code (the skill's upstream is https://github.com/microsoft/skills), so this is a runtime external dependency that can execute remote code.
