WHY IT NEEDS A POLICY

Why wiki_asset_rename needs a policy

Renaming a file is a Write operation: it modifies data (the asset's name) but is reversible (can be renamed back). It does not delete, execute code, move money, or trigger external logic. Severity is medium because widespread renaming could disrupt wiki navigation and references if done maliciously, but the operation itself is not destructive or irreversible.

From the tool's definition Tool name and description indicate 'Rename an asset (file)' – a modification operation that changes file metadata reversibly.
