Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses nothing about side effects, persistence, permissions, or follow-up behavior. Annotations only provide negative flags (readOnlyHint=false, idempotentHint=false, destructiveHint=false), so an agent cannot infer whether the request creates a ticket, updates a backlog, or sends a notification.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
