RISK

Why GOOGLESUPER_CREATE_EVENT is rated Medium

This tool creates new calendar events, which is a reversible write operation. An AI agent could misuse it by scheduling unwanted meetings, flooding a calendar with spam events, or creating fake meeting invitations, causing disruption to the user's schedule and potentially affecting business operations. However, events can be deleted or modified, so it is not destructive.

From the tool's definition Tool description states it creates a Google Calendar event and requires 'calendar write access.' The verb 'create' combined with 'write access' confirms this modifies data.
