WHY IT NEEDS A POLICY

Why create-pull-request-review needs a policy

Creating a PR review adds metadata and comments to a pull request but does not delete data, execute code, or move money. It is reversible (reviews can be edited or dismissed). While it affects code review workflow and could delay/influence merge decisions if abused, it does not have destructive or execution side-effects.

From the tool's definition Tool name 'create-pull-request-review' and description 'Create a review on a pull request' indicate creation of new data (review records) on an existing PR. This is a write operation that modifies PR state reversibly.
