WHY IT NEEDS A POLICY

Why sort_file_content needs a policy

This tool modifies the content of an existing file by reordering its lines and optionally removing duplicates. This is a reversible write operation (file content is overwritten with sorted content), but not irreversible deletion. The 'duplicate removal' feature could cause data loss if misused, but the primary action is a content transformation write.

From the tool's definition Sort the lines of a file. Supports ascending/descending, numeric sorting, and duplicate removal.
