## Why circles_delete is rated Critical

This tool permanently removes a circle/team entity and cannot be undone. Deletion is irreversible and destroys data, placing it in the Destructive category. Severity is high because deleting a team affects multiple users and shared resources, though it requires owner privileges which limits blast radius somewhat. Not critical because the privilege requirement provides some guardrail against casual misuse.

From the tool's own definition: "Tool name 'circles_delete' and description 'Delete a circle/team' explicitly perform irreversible deletion of a data structure (circle/team). The requirement for 'owner privileges' indicates administrative scope."

## Use case
