Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure but only implies read-only safety through the word 'Get'. It fails to specify which DEX(s) are queried (IRIS, SteelSwap, or both), whether data is real-time or cached, what 'yields' specifically represents (APR, APY, claimable tokens), or any rate limiting concerns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
