Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses key behavioral traits: it returns details (not just summaries), is paginated, and has a fixed page limit of 100. However, it doesn't mention other important behaviors like rate limits, authentication requirements, error handling, or what 'detail' includes (e.g., fields returned).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
