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 behavioral traits. 'Delete network maps' implies a destructive action, but it does not state whether deletion is permanent, whether it can be undone, or if it has cascading effects on related entities. This lack of detail leaves the agent under-informed about the impact of invoking the tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
