Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations available, the description carries the full burden of behavioral disclosure and does so well. It reveals the 200-line limit, chronological ordering, returned line contents, pagination mechanism, and the absence of any authentication requirement. This is substantial transparency for a simple read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
