Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already disclose that this is a non-read-only, non-idempotent, open-world, non-destructive create operation, which is most of the behavioral signal available here. The description adds nothing beyond that – no indication of what gets created or mutated, whether the source preset is changed, or what side effects 'apply' triggers.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
