WHAT IT DOES

What apply_style_to_range does on Docx

AI agents use apply_style_to_range to create or update resources in Docx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment.

RISK

Why apply_style_to_range is rated Medium

The tool modifies document content (paragraph styles) reversibly through OOXML-level manipulation. This is a Write operation as it changes document state but does not delete data or execute arbitrary code. Severity is medium because bulk style application could affect document appearance and usability, but the change is reversible and does not compromise data integrity or have destructive side effects.

From the tool's definition Tool name 'apply_style_to_range' and description 'Apply a style to a list of paragraphs by their paraIds' indicate modification of document formatting properties.
