Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose the result composition and the $0.01 price, which is useful behavioral context. However, 'HTTP x402' is cryptic and unexplained, and there is no mention of errors, rate limits, authentication, or other behavioral edge cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
