Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
While the description doesn't contradict the annotations (readOnlyHint=true aligns with 'Get'), it adds no behavioral context beyond what annotations already provide. It fails to disclose error handling (e.g., invalid ID), return value structure, or cache behavior, despite the absence of an output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
