Why undo_last_edit is rated Medium

While 'undo' suggests reversibility, the mechanism—replacing the active document with a backup file—is a write operation that modifies the current document state. It is reversible (undo can be undone via redo or further backups), distinguishing it from Destructive category. The high severity reflects that an agent misusing this could revert important edits across a document, causing loss of recent work.

From the tool's definition Tool description states it replaces the current document with a backup from before the last save (마지막 저장 전 .bak 백업과 현재 문서를 교체해), effectively reverting edits. This is a modification operation that alters document state.
