Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds a meaningful non-obvious behavior: unauthorized related fields are masked. However, it does not clarify what masking means in practice or what happens if the caller lacks access, so the added context is useful but partial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
