Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden. 'Get' implies a read operation, but it does not explicitly confirm safety, rate limits, or whether pagination is automatic or requires manual page iteration. The phrase 'pagination support' hints at behavior but leaves key details undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
