Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, indicating a read operation. The description adds that it resolves a single item, which is consistent and slightly extends behavioral understanding. However, it omits any mention of error behavior (e.g., unresolved identifier), return format, or side effects beyond the read-only nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
