Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full behavioral burden. It does name the output categories (allowlist and buy-sell flags), but it does not explain the flag values, return format, network handling, or failure behavior. This leaves key operational details implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
