Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide critical behavioral hints (destructiveHint=true, readOnlyHint=false, idempotentHint=false, openWorldHint=true), but the description adds minimal context by specifying it's a POST operation. It doesn't elaborate on what 'remove' entails (e.g., data deletion, resource cleanup) or potential side effects beyond annotations. No contradiction with annotations exists, and the description adds some operational detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
