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

• Potentially malicious external URL detected (high risk: 0.90). The workflow uses third-party GitHub Actions that are fetched and executed at runtime (e.g., actions/checkout@v4 and dtolnay/rust-toolchain@stable), which are external repositories run by the CI and thus execute remote code during the skill's workflow.
