WHY IT NEEDS A POLICY

Why generate_ui5_controller needs a policy

This tool creates new source code files/content (a controller skeleton with lifecycle hooks and JSDoc comments). This is a reversible write operation—generated code can be modified, replaced, or deleted. It does not execute code, delete existing content irreversibly, or move data/funds.

From the tool's definition Tool description states it will 'Generate a SAPUI5 controller skeleton', which creates new code artifacts. The word 'generate' indicates code creation rather than retrieval or execution of arbitrary operations.
