Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already communicate read-only, idempotent, and non-destructive behavior, and the description aligns with these. It adds useful context about the 'live gateway' origin and return content, but does not mention auth requirements or other behavioral nuances. No contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
