Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It adds a useful note about forwarding Wallet+ Bearer or x402 payment headers, indicating authentication/payment behavior. However, it does not mention read-only behavior, rate limits, or pagination traits, leaving gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
