Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotation Contradiction: readOnlyHint is false, yet the description says 'List drops' and 'Returns ...', which describes a non-mutating read operation. Even though the description is behaviorally honest about auth and output details, it directly conflicts with the structured readOnlyHint annotation, so it must score 1.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
