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. It does not disclose that this is a mutation requiring an access token, whether votes can be changed or removed, whether the operation is idempotent, or what the response contains. Only the basic scope (post or comment) is mentioned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
