Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, and the description confirms this with 'Retrieve'. It adds useful context by specifying 'your account' (self-scoped) and the kind of data returned (wallet address, balance, settings). However, it does not disclose any additional behavioral details such as authentication requirements or rate limits, though the annotations cover the basic safety profile.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
