Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the qualifier 'summary', indicating the tool returns a condensed version rather than full standards, which is mildly useful. However, it does not disclose additional behavioral traits such as caching, response format, or any special handling beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
