Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It states the tool returns details of one record, which suggests a read operation. However, it does not disclose any behavioral traits such as authentication requirements, rate limits, or error conditions. The description is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
