WHAT IT DOES

What insert_page_break does on Google

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

WHY IT NEEDS A POLICY

Why insert_page_break needs a policy

This tool modifies document structure (page breaks are formatting/structural elements) but does not delete data, execute arbitrary code, or perform financial transactions. The modification is reversible (page breaks can be removed), making it a Write action rather than Destructive.

From the tool's definition insert_page_break inserts a page break at a position in a Google Doc — a structural modification that alters document layout and formatting.
