Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description is consistent with readOnlyHint=false, but adds nothing beyond it: no statement of whether the withdrawal is reversible, what happens to the node's other associations, whether permissions are required, or what an error looks like. For a mutation exposed with a single annotation hint, this is a substantial gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
