WHY IT NEEDS A POLICY

Why update_files_categories needs a policy

This tool modifies file category metadata but does not irreversibly delete data or execute arbitrary code. The update operation is reversible, making it a Write action rather than Destructive. Confidence is slightly reduced (0.85) because the description appears truncated ('Note that file categories where...'), leaving some ambiguity about full scope, though the core function of updating categories is clear.

From the tool's definition Tool name 'update_files_categories' explicitly performs an update operation on file categories. The description confirms it 'Updates a file category' - a reversible modification of data.
