Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It states it gets data, which implies a read operation, but does not disclose any behavioral traits such as data freshness, auth requirements, or error handling. However, the tool is simple, and the description is 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.
