Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, and the description is consistent with a safe read-only recomputation. It adds useful behavioral context beyond the annotations: it returns each check result plus the raw data needed to re-verify independently on-chain, which tells the agent what the operation actually produces.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
