Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=true and idempotentHint=false, so the description adds nothing on safety or side effects. There is no mention of required permissions, what happens on duplicate CWE ids, or what the request body should contain for a write endpoint with zero documentation elsewhere.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
