Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the state change but does not disclose whether the operation is reversible, idempotent, or requires special permissions. It also does not mention side effects or error conditions, which is a gap for a mutating tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
