## Why create_sheet is rated Medium

This tool creates new sheets within a spreadsheet, which is a reversible write operation. It modifies data structure by adding new sheets but does not delete, execute code, or move financial resources. The severity is medium because misuse could create numerous sheets consuming quota or cluttering the workspace, but the action is reversible through deletion.

From the tool's own definition: "Tool name 'create_sheet' and description 'Create a new sheet within an existing spreadsheet' indicate data creation and modification within Google Sheets."

## Use case

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