Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It indicates a read-only listing operation ('List all available SQL dialects'), which implies no destructive actions, but does not disclose details like rate limits, authentication needs, or output format. The description adds basic behavioral context but lacks depth for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
