Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states what the tool lists, but does not describe that it reads the memory dump, whether it may be slow, or what constitutes 'available' plugins. This leaves significant behavioral aspects undefined.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
