Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of disclosure. The verb 'Explain' implies a read-only, informational operation, but the description does not explicitly state that it has no side effects or require any permissions. Since the tool is purely explanatory, this is a minor gap, but more explicit transparency would improve the score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
