WHY IT NEEDS A POLICY

Why crear_repositorio needs a policy

This tool creates a new GitHub repository, which is a reversible write operation (the repository can be deleted later). It does not delete, execute arbitrary code, or involve financial transactions. Severity is medium because creating repositories could expose code publicly or consume organizational resources if misused.
