WHAT IT DOES

WHY IT NEEDS A POLICY

Why git_steer_repo_create needs a policy

Creating a repository is a reversible write operation—the repository can be deleted afterward. However, severity is high because an autonomous agent creating repositories could lead to resource sprawl, potential cost implications (private repos), namespace pollution, or use of the account's reputation for malicious purposes.

From the tool's definition Tool name 'git_steer_repo_create' and description 'Create a new GitHub repository' indicate creation of a new resource. The server context shows it 'enables control over repositories' through natural language, confirming write capability.
