Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds pagination-stability guidance ('Keep ordering unchanged across cursor pages'), but that constraint is already repeated in the schema's cursor and order descriptions, so the added value is marginal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
