Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing side effects了好久. However, the description only states the action with no mention of mutability, permission requirements, reversibility, or effect on player state. It does not clarify whether the item appears in inventory, whether it replaces existing items, or if any feedback is returned. This is a meaningful gap for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
