Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint, so the agent knows it is safe. The description adds the specific scope (Wikiquote, title+fulltext) but does not elaborate on behavior like pagination, response format, or any constraints. It is adequate but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
