Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, adequately covering safety and side-effect profiles. The description adds no additional behavioral traits (e.g., rate limits, permission requirements, or what happens on invalid ID). It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
