WHY IT NEEDS A POLICY

Why schema_generate_tab needs a policy

This tool creates new metadata files (custom tab definitions) in a Salesforce DX project, which is a reversible modification to the project structure. While it does not directly modify org data, it generates source files that would typically be deployed to an org. This falls under Write (creates reversible artifacts).
