Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Get trading keys' implies a read operation, but it doesn't disclose behavioral traits like authentication requirements (though parameters hint at it), rate limits, what 'trading keys' entail (e.g., API keys, permissions), or the response format. It lacks critical context for safe and effective use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
