Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior, but it only states 'Get', which implies a read operation without explicitly confirming no side effects. It also provides no details about the return value, format, or prerequisites (e.g., wallet initialization), leaving significant behavioral transparency gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
