Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so safety is covered. The description adds genuine behavioral context by naming the four analysis dimensions used, but says nothing about cost, rate limits, or what happens when a market ID is unknown or illiquid.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
