Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It only states it returns 'normalized public room details', but doesn't disclose behavior like error handling, rate limits, or whether the id must be a specific format. The description is minimal for behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
