Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, yet it only says 'create'. It does not disclose whether the wing must pre-exist, whether the room name must be unique, what happens on conflict, what permissions are needed, or what the response contains. For a mutation tool 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.
