Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the description's 'Get details' is consistent and adds little. It does mention 'including test count,' which is a useful detail about the response content, but doesn't disclose other behavioral traits or potential limitations. No contradiction found.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
