Automating with GitHub Actions

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

• Potentially malicious external URL detected (high risk: 1.00). The workflow uses external GitHub Action repositories (e.g., actions/checkout@v4 -> https://github.com/actions/checkout and docker/setup-buildx-action@v3 -> https://github.com/docker/setup-buildx-action) which are fetched and executed at workflow runtime, so they are runtime external dependencies that execute remote code required by the skill.
