Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds minimal behavioral context beyond the annotations. It states what the tool does but does not disclose any side effects, prerequisites, or whether the operation is idempotent. With readOnlyHint=false and destructiveHint=false, the annotations already convey that it is a non-destructive write, but the description does not enrich this further.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
