Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, so the safety profile is covered structurally. The description adds nothing beyond that — it does not say whether deletion is permanent, whether it cascades to ingredients/meal plans, or whether a confirmation is required. For an irreversible mutation the extra context would be valuable and is absent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
