Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds that scoring is 'weighted' and returns 'detailed breakdown', but offers no insight into scoring methodology, parameter influence, or edge cases. This meets the minimum bar given annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
