Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the read-only nature is covered. The description adds the concept of Martingale score scoring and optional filtering, but does not disclose ordering, return format, or other behavioral details. It meets the baseline with annotations but adds limited extra context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
