Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, so the safety profile is covered. The description adds that the plan includes species, plants, products, warnings, motivations, and guides, which gives useful behavioral context about the scope of the result. This is helpful, though not rich enough to exceed a baseline given the strong annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
