Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, openWorldHint=true, so the safety profile is covered and there is no contradiction. The description itself adds zero behavioral context — no mention of what fields get replaced, permissions, or side effects of a full update.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
