WHY IT NEEDS A POLICY

Why create_github_workflow needs a policy

This tool creates/generates a GitHub Actions workflow file. It is a Write operation — producing a new file that defines CI/CD automation. While the resulting workflow could trigger powerful automated processes, the tool itself only generates/writes the file. Misuse could introduce malicious CI/CD pipelines, giving it a medium severity rating.
