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. It discloses that the tool returns APY, min stake, and active flag for pools. However, it does not mention data freshness, caching behavior, or whether the list is filtered (e.g., only active pools). For a simple read-only tool with no parameters, this is adequate but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
