WHY IT NEEDS A POLICY

Why change_font_style needs a policy

This tool modifies document formatting in a reversible manner (italic/normal toggling), which is characteristic of Write category. The severity is low because font styling changes have minimal blast radius — they alter appearance only, not content structure or data integrity. Confidence is high due to explicit description of the modification action.

From the tool's definition Tool description states it can 'Change the font style (italic/normal) of text in a document' — a modification operation. Sibling tools like 'append_text', 'apply_font_formatting', and 'change_font_size' confirm this server performs document edits.
