Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations include 'destructiveHint: true', but the description does not explain why it is potentially destructive (e.g., cost implications or state changes). The only behavioral note is 'Cost: $0.01 USDC via x402.', which addresses some external consequence but not destruction. No contradiction, but significant gap given the annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
