Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this as readOnly, idempotent, and non-destructive, so the safety profile is covered. The description adds the 'connected' scope, which is a small behavioral constraint, but it doesn't disclose what happens if no account is connected or what the returned profile contains. Given the strong annotation coverage, 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.
