Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It describes what data is returned but doesn't disclose behavioral traits like read-only nature, authentication needs, or rate limits. For a stateless query tool with no parameters, the description is adequate but could be more explicit about being non-destructive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
