Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, and the description does not contradict that. It adds context about the output structure (structuredContent.body vs metadata) and a semantic nuance (confirmation vs evaluation), but does not disclose potential side effects, authentication, or rate limits. Since annotations cover the read-only nature, the added context is modest.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
