Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already indicate that this is a mutating but non-destructive operation (readOnlyHint=false, destructiveHint=false). The description adds no behavioral context beyond the word 'create', such as side effects, defaults, duplicate handling, or whether the client is immediately available.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
