Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It mentions 'Pro tier', indicating access restrictions, but does not disclose other behavioral traits such as side effects, authentication requirements, rate limits, or what happens if the entity_slug is invalid.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
