Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the safety profile is available structurally. The description adds nothing beyond that — no mention of what payload shape is accepted, duplicate handling given non-idempotency, permission requirements, or side effects on the asset class tree. It does not contradict the annotations, but it contributes zero behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
