Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It does communicate that this is a read-only listing operation and that only names are returned, which is useful. However, it does not mention pagination, ordering, permissions, or whether secret values are intentionally excluded beyond the 'names only' phrase.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
