WHY IT NEEDS A POLICY

Why create_page needs a policy

This tool creates new pages and routes in a web application. Creation of application pages is a Write operation—it modifies the codebase by adding new routes and pages, but these changes are reversible (pages can be deleted or modified). It does not execute arbitrary code (Execute), delete data (Destructive), or move money (Financial).

From the tool's definition Tool name 'create_page' and description 'Create page/route with routing setup' indicate creation of application routes and pages, which are reversible modifications to frontend/backend code structure.
