Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=false, so the description is consistent with a write operation. It adds the HTTP method and endpoint, which gives a bit more context, but does not disclose any side effects, permission requirements, or error behavior beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
