Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate it is not read-only (readOnlyHint=false) and not destructive (destructiveHint=false). The description does not add any behavioral detail beyond that, such as idempotency, side effects, or error conditions. For a mutation tool, more transparency is expected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
