Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of behavioral disclosure. 'Reorder' implies changing order and likely persistence, but nothing is said about whether all config UUIDs must be provided, whether the operation replaces the entire ordering, or if there are side effects. This is a minimal mutation description with no behavioral detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
