Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds nothing further: no indication of what the response includes (rates? room types? the referenced booking IDs?), no auth or rate-limit context. The 'bron ID'larini' phrase hints at extra behavior but is never explained.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
