Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of disclosure. It adds the breakdown categories and optional date filtering, but does not clarify that the tool returns all pools without pool-specific filtering (no pool parameter exists), nor does it specify the output shape. The verb 'Get' implies read-only, but there is no explicit statement about side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
