WHY IT NEEDS A POLICY

Why toggle_pinned_stories needs a policy

This tool toggles the pinned state of stories on a Telegram profile. It modifies the presentation/state of existing content (pinning or unpinning), which is a reversible write operation. It does not delete content, execute code, or involve financial transactions. Severity is medium because misuse could affect profile presentation and visibility of stories for a personal account.

From the tool's definition Закрепить/открепить мои stories в профиле (доступно бессрочно) — pin/unpin stories in profile
