WHY IT NEEDS A POLICY

Why sync_backlog_labels needs a policy

The tool performs label synchronization which involves writing/modifying metadata on GitHub issues. While label changes are reversible (can be undone), the tool modifies issue state. This is categorized as Write rather than Execute because it's not triggering external operations or code execution—it's applying predefined label updates.

From the tool's definition Tool description states 'optionally fix issues missing required priority/type labels', indicating the tool can modify issue labels. The capability to add/update labels constitutes reversible data modification.
