Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. 'Replace' implies overwriting the existing lineup, but it does not explicitly state that existing cases not in the new list will be removed, nor does it disclose any other behavioral traits such as atomicity, permission requirements, or validation failures. The description is too sparse for a destructive mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
