## Why list_inboxes is rated Low

This tool retrieves or enumerates existing inboxes without creating, modifying, or deleting data. It is purely informational. Severity is low because listing inboxes reveals metadata about email account structure but does not expose message content or enable harmful actions on its own.

From the tool's own definition: "Tool name 'list_inboxes' and description 'List all inboxes in the account' indicate a query/retrieval operation with no side effects."

## Use case

AI agents call list_inboxes to retrieve information from AgenticEmail without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
