Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description's genuine contribution is the `team:read` scope requirement, which annotations do not express; however it says nothing about what the returned configuration comprises or whether it is cached/eventually consistent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
