Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare destructiveHint=true and readOnlyHint=false, so the agent knows this is a destructive operation. The description adds 'Permanently delete', reinforcing irreversibility, which is useful context beyond the generic annotation. However, it does not disclose any other behavioral traits such as what happens to associated sync configurations, whether permissions are required, or error behavior if the connector does not exist. With annotations present, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
