Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of behavioral disclosure. It states that detailed information is returned, but it does not describe what fields the 'detailed information' contains, whether the response includes nested objects, or how errors are handled. For a read tool, some indication of return shape would add value beyond the one-line purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
