Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden, and it does so thoroughly: it discloses cost, payment routes, non-coverage by API key, chain (opBNB), reveal delay behavior, identity model, and the crucial semantic that it attests when not whether. This is exceptionally transparent for a paid on-chain tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
