Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals that data is sent to OpenAI (an external service), but it does not disclose authentication requirements, rate limits, latency, costs, privacy implications, error behavior, or whether the operation is asynchronous. This lack of detail for an external API call is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
