Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries full burden. It mentions the data source (Census Bureau) and default behaviors for optional parameters. However, it does not discuss error conditions, data freshness, or any limitations beyond year range. For a read-only data retrieval tool, this is adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
