Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false and destructiveHint=false, so the safety profile is known, but the description adds no behavioral context: it does not explain how ordering is applied, whether all configs must be supplied, whether positions are absolute/relative, or whether the operation is idempotent. For a mutation tool, it contributes nothing beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
