Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. 'Logical AND.' does not explain what the tool does beyond the basic operation, such as how it handles input expressions, what the output entails, or any constraints like error handling or performance. It lacks details on return values, side effects, or any behavioral context, making it insufficient for informed use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
