Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral disclosure. It does mention the new subscription link being generated, which is useful, but it does not disclose whether the action is reversible, what happens to the old link, impact on active connections, or any permission requirements. For a mutating 'revoke' action, this is a significant transparency gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
