Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It discloses that the tool behaves exactly like list_my_ideas (by being an alias), which is a transparent statement of its behavior. It does not detail side effects, but for an alias none are expected beyond the target tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
