Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, covering the basic safety profile. The description adds that it uses POST and is 'legacy', offering some context, but does not disclose side effects, rate limits, or operational nuances beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
