Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety and open-world profile. The description adds that results are 'normalized' and come back in multiple sections (shows, episodes, top results), which is useful, but it does not elaborate on rate limits, pagination, or auth. With annotations carrying the safety burden and an output schema present, a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
