Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false and destructiveHint=true, which is otherwise confusing for a 'get' operation. The description resolves this by disclosing that the call costs 0.1 AGENT, i.e. it spends funds — exactly the behavior the annotations flag. It does not, however, state whether a funded/unlocked wallet is required or whether the charge is per-call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
